Cons

  • This has excellent strong tight clean bass as far as hard hitting punch goes, but as far a low end subbing,it needs more power, it can create the sound very well but can't force it out strong enough for my tast.klips 600 watt can shake the walls ,floors and be heard two houses away, but it lack tight punchy bass like high pitch bass.JustWantTheBest

    These subs would definitely give you the best bang for your buck!! You’d never guess such a small box could kick out that much bass!! Definitely loved these subs...when they were working. I bought 2 Supercube 4000’s so I could put a sub in corners adjacent from one another to have the bass really fill up the room. They didn’t have them in stock at the store so we ordered online and when we brought them home, one of them sounded like the speaker was already blown, and the other kept turning on by itself so we had to keep it unplugged when we weren’t using it. We decided to exchange them, and with the second set we ordered one of them worked at first, but the next time we tried to use it to watch a movie, the display read “ON”, but there was no sound coming from it nor could I control it with the remote. The other of the second pair had the same issue with turning on by itself and we’d have to keep it unplugged when we weren’t using it. We were really bummed because these HIT HARD and even the low-end bass sounds awesome for the price!! Unfortunately, we decided to return them because every single one of the four we bought were defective. I’m not sure if it’s just the 4000 that has had problems, but it’s on sale again for cheaper than what we had initially paid for them. We’re thinking of possibly investing in a pair of the 6000, or downgrading to a pair of the 2000. One thing is for sure, the neighbors were complaining about the pair of 4000 shaking the walls, and that’s the only complaint I’d ever consider a compliment LOL!! When you’re spending $700/sub, you definitely want to be confident that they’re not going to give you issues down the line. We just didn’t feel confident enough in them to keep them.

    Huge Bass, Little Box!

    I'm a home theatre geek and audiophile. Excellent audio is a must, whether it's for home theatre or 2-channel audio. Recently we remodeled our living room and did the whole TV above the fireplace thing. Since I've already got a dedicated home theatre, one of the prerequisites for the living room was space saving for everything! My wife wasn't about to let me install a 5.1 system, and I'm not about to rely on our flat screen tv's audio either. So, we met in the middle with the agreement that we'd have a sound bar with a seperate sub as long as it wasn't a ridiculously massive sub like my two Power Sound Audio XV-30se' in my theatre. I've never been a big fan of the little box sub concept either. The audio gurus will tell you it's simple physics (if there is such a thing) that in order to get truly deep bass down to 20hz or below, you need the appropriate "box space" to move that much air and to reach subsonic frequencies. With all that being said, I had quite the challenge ahead of me! I don't like sound bars and until recently I didn't like small box subs. I want a true surround sound experience that can hit the audible sound spectrum from 20hz-20Klhz. So, I bought the B&K Panorama 2 and the Def Tech 4000. I was simply astounded that the Def Tech could hit such low frequencies with authority! I haven't actually measured just how low this little guy can go just yet, but based off first impressions and being able to tweak this sub with its handy little remote control, I was simply blown away. My room size is 3400 cubic feet, and this Def Tech 4000 can pressurize it with little to no effort. It's beyond me how it can do this. The build quality is fantastic as well. It's not for those that have pets, as I can imagine how inviting it would be to a cat, with its all sides material wrapped box. But that's the only draw back I can think of. This is the best sub you're going to find for $1000 or under. I'm very satisfied on all fronts with the performance of this subwoofer!

    So after much reviewing I narrowed it down to this- Here's why with pros & cons. First off I love the sub and only keep it around 25% for my small room of 9.5x13. Ive had it for a month now, & since it is a small room I wanted a small subwoofer, still I looked at some larger sets such as the Martin Logan's and popular SVS in which I considered them but even with their smallest sub, it is still quite big. Now the thing is, for the price svs is great bang for the buck, but if you need the smaller size and don't mind the extra $$ then this truly is the best small subwoofer. Other subs I noticed sounded louder but super muddy and lack of detail that I did not know a subwoofer had so much of until I did the side by side tests. Many other subs I tested such as the klipsch 12" and Dynamo 700 had more output, but just wasn't as good in my opinion. Then in the future I plan on getting 2, which is always better then 1, I will then have the output power and all the awesome small size detail this guy has. Bravo & thank you DefTech! *NOTE: Friggin amazing to actually have a remote for you sub which this comes with that i don't know other subs that do that, comes so much in handy!!! Also every 30 mins to an hour or so when the sub is not on, it displays "OFF" , that gets a little bit annoying, there should hopefully be a way to get rid of it but never took the time to try to figure it out 1st picture is the day I got to hear comparisons with the klipsch, logan, b&w & super cube. other is it in my set up (in future when I move ill give it more breathing room) and shows how nicely hidden and how well this sub fit into small spaces. Regardless of the size of the room, at least one sub is always necessary- hope I helped!

    Purchased at the end of January 2017, the Super Cube 4000 has completed its break-in period and the bass sounds very tight and deep. I have the unit set at about half volume with the equalizer set to OFF, which sounds the most natural for my tastes. I mostly watch HD movies and TV shows on my Sony 55” KDLHX800 flat screen. I also listen to digital music streamed from my computer and off the internet. Occasionally I watch movies on DVD. This new unit replaced a ten-year-old ACI Force subwoofer with a 10” driver and a 250Wrms analogue amplifier. The Super Cube 4000, with its 8” active driver, 2x 8” passive resonators and 1200-watt digital amplifier provides more than sufficient controlled bass output for my home theater system. My living room with connected dining area is approximately 15’ x 25’ x 8”. I use a Yamaha RX-A2040 home theater receiver to deliver the LFE signal to the subwoofer and the incorporated YPAO automatic speaker setup program to integrate the subwoofer with my main Magnepan MG-12 planar speakers. The Super Cube 4000 more than meets my needs, seamlessly blends with my other speakers. It may not provide the thunder clap of a 12” or larger unit, but it does provide very realistic and extended bass at normal listening levels and for those elevated movie soundtracks. Its small footprint also allows it to be placed in the best location without being intrusive. Highly recommended!

    I am using this with a 5.1 set up including two floorstanding 9060's up front which also have subwoofers built into them. When everything is working properly and tuned this subwoofer sounds fantastic and really gets nice lows that are missing from the two front towers (those really act more like heavy mids anyway) The reason I have given it 4 stars instead of 5 is because after about a month or less of use, there is a really annoying vibrating noise coming from the cabinet. It does not sound like it is a blown speaker and when investigating it sounds more like there is something inside that the woofer may be vibrating against or maybe loosened up. It drove me crazy because it sounded like something vibrating in my living room and I tried to track it down just in case it was not from the sub. After not having luck tracking it down I determined it had to be this speaker, so I took it down to best buy so they could hook it up to their audio room and confirm what I thought. Sure enough it was a bad unit and they happily ordered me a new one to replace this one. I haven't gotten that replacement yet, but I feel pretty confident that it will sound much better. Aside from audio quality I really like the size of this thing. I have it sitting behind our sofa (I ran a subwoofer line in the wall to the receiver media panel up front) and it barely takes up any space at all. Overall I am very happy with this subwoofer and will likely change the rating to 5 stars once the new one arrives and gets some decent use.

    I initially purchased a Klipsch R-12SW, but ended up returning it due to its very large dimensions. The SC4000 is very small and came in a nicely secured package (heavier than I expected). The overall exterior build quality is 10/10 and you are paying for that piano finish, gold plated terminals, rubber covers for those gold terminals, little remote, etc. It's a fancy little sub, but it can output nice clean bass for either music or home theatre. A single SC4000 is sufficient, but I ended up purchasing 2 of them (to avoid flat spots) and have them placed on each side of the TV. Since I have 2 of them, I generally keep the volume between 15 and 20 (40 is max) and it's more than sufficient for my needs. I had the opportunity to compare it to the Klipsch R-12SW side by side (which is a 12" 400W ported sub) and I can tell you that you'd be kidding yourself if you think that SC4000 can output the same bass as a decent 12" sub. At 30% gain, the Klipsch was as loud as the SC4000 at volume 25/40, while producing deeper and tighter bass than the SC4000. The Klipsch got even stronger at 40% gain without any strain, while the SC4000 seems to be electronically limited to prevent it from killing itself as you increase the volume. I am not knocking the SC4000 at all, and at the end of the day I ended up keeping it, but I just want people to have real expectations.

    EARTHQUAKE!!!

    I've had this sub for a year and I am overall pleased. The remote, along with the digital display, is super handy. Being able to tune the phase to your seating position makes a HUGE difference in sound. I like the different EQ settings as well. It does make a difference when watching a movie or listening to music. I don't turn this sub up too loud so I can use the EQ1 setting witch gives you lower lows. When I do turn it up loud, I just leave the EQ off. I usually have the volume up to 10 and up to 16 when I really want to shake the house. It goes up to 40 but there really is no need to go that high. This is the first sub that I've paid over $150 for and there is no comparison in sound, volume and quality. However, there does seem to be some lacking in the upper hz range. I have a car with a factory sound system and I can feel the bass in this upper range, but with this sub it seems to be a little weak, but this is noticeable when playing music. For movies, this sub makes the earth shake and shatters molecules. No complaints there. There were a few times, when I first got this, that I got some distortion when watching a movie but this sub is so tuneable that I've never had that problem again. I realize that this is not a high end sub so this will not have the sound or impact of a high end sub. However, it doesn't have the huge price of one nor take up a giant amount of space either. All in all, this is a fantastic sub for the money. I thoroughly enjoy it and love its features. I was going to get the sc2000 but I am glad I went for the extra features with the sc4000.

    Tough little sub

    Bought from BB Magnolia. Auditioned the Supercube 2000 for about a week then blindly ordered the 4000. Initial impression : goes very low and is very loud, especially given the 8" driver. I currently have the sub paired with some powerful Polk towers (with built in subs) and the sc 4000 could easily over take the towers. My set up is in a tiny bedroom currently and I have to keep the sc turned down most of the way. Turned up it will pressurize this little room. I cannot wait to set this up in a bigger area my expectation is that it will fill up nicely. My recommendation is buy this speaker and keep it in the open to show off. It sounds great a looks prettier than any sub I have ever seen. A side note : This is not a bedroom sub. On the contrary it needs room to breath. I'm certain the sc 4000 will fill most living rooms and satisfy most audio enthusiasts. Maybe a select few will wanna consider the sc 6000 and up but I really dont know many homes, vaulted ceilings being the exception, that would need it.

    I purchased this on the recommendation of a Magnolia associate after finding out that the sub woofer I was looking for was not carried by any of the stores in my area. I had the magnolia person give me a demo of the unit, which they didn't know how to operate I realized after I read through the manual. Putting it in place, it has really low range into the lower frequencies which is what I was looking to get a sub for as my speakers were good down to 70hz. The power is no where near 1200w as the associate and specs mentioned, more like 100 or 200w. The associate and sub information both said that 1200w was the RMS power, this is an outright lie. I will never buy any speakers from this brand again, their completely made up specs show when you go to actually use the equipment. When I asked about the performance of the equipment not being up to spec, I was told to upgrade to their next model or to add another sub. You should have seen the looks when I returned it too, like I was a criminal of some kind for wanting it to live up to what was promised. If you don't want returns then don't sell products that blatantly lie about their performance.

    If your looking for Goliath, this is not your subwoofer. BUT if you want bang for the buck and the especially the space...now we're talking. At full price some might think this a little pricey because of the size. What was important to me was to have an amazing movie experience without having the speakers overwhelm the room or my wallet. This was the perfect answer for me. These subs shake the floor by themselves, even with out help from my other sub. What makes them worth the upgrade over the SC 2000? Beside more power and accuracy, it come with a remote and EQ settings that can be adjusted from the listening position. This makes it simple and fast to optimize for both movies and music. I like a deal, so I waited until the SC4000 went on sale just above normal SC200 price. In any case, worth the upgrade for sure!

    I have had this subwoofer for 8 months and I love it. It replaced a Polk Audio 100Watt sub. I can't believe the bass and power this thing puts out. We were recently watching Oz and there was a scene where one of the winged monkeys landed with a loud thud. Everyone jumped and it shook the room!! We all felt the bass in our chests and the sub was set to 40%. The wireless remote and the disappearing display are icing on the cake. I compared this to the $1500 Bowers and Wilkins CM Sub. The SC 4000 had more punch and the same quality sound for $700 less. OK, the B&W won the sound quality by a nose but cost a lot more! BTW, the sub is in my great room with 20 ft ceilings. If you have the funds buy this sub.

    Got this sub hoping to get more power than my 12 inch 600 watt klips but was a little disappointed. This has excellent strong tight clean bass as far as hard hitting punch goes, but as far a low end subbing,it needs more power, it can create the sound very well but can't force it out strong enough for my tast.klips 600 watt can shake the walls ,floors and be heard two houses away, but it lack tight punchy bass like high pitch bass. Low end bass klips blows it out the water and into space, high pitch bass sc4000 kick klips's azz, If you want strong power that shakes walls and chest get klips.if you don't need too much power than sc4000 is better,it's more well rounded just lacks power. I hope this help. Ps together there a match made in heaven .

    I recently completed a new home theatre and opted for the supercube 4000 based on multiple expert reviews, it's compact design and reputation of the brand. I must admit I was really nervous dropping almost a grand without having heard the sub however best buy assured me my satisfaction was guaranteed. From first listen six months ago to today I have been blown away. From movies where you really are looking for enveloping lows with plenty of power to all types of music this sub has no doubt aced the challenge. I would highly recommend this product to any audiophile looking for a sub.

    Ordered the Super Cube 4000 without hearing it first, which for me is a first when it comes to audio. Is replacing a Cambridge Soundworks p200 which died and had been without bass for like 9 mos. All I can say is WOW this thing puts out impressive bass. It is tight, clean and full. It sounds great for movies as well as music across all generas. It shakes my living room (18x22 10'ceilings) and literally makes me giggle when I crank it up when the boss is gone... I did by by the way listen to a bunch off subs in store like the B&W, Klipsch, Sonos? and few other Def Tech and to me, this thing outperforms. Enjoy!

    Very impressive loudness for a box this size. I have a difficult room acoustically - 14 ft cathedral ceilings and an open floor plan, also don't want a speaker system to be the focal point, so the small size of this sub attracted me, as did the sub-sonic performance (not many subs go below 20 hz). The loud pounding during loud special effects was impressive, but during quiet periods, just dialogue, there was an underlying low bass presence that was excessive and unnatural. I returned it, accepted the laws of physics, and am now using 2 subwoofers, 10" drivers, 300 watt amps, ported, and am getting beautiful, precise low bass performance.

    Definitive Technology is one of the high value manufacturers. They may not be the best products of their respective classes but they certainly perform well and are of high value. In theatre applications, unlike its 2-channel counterpart, sound image (and arguably critical sound quality) is not as crucial as 2-channel audio. It is mostly due to the actual sound recording on movies that rely on surround sound technology. The super cube is an excellent product for home theatre application - small, powerful, and flexible. Highly recommended.

    The SuperCube 4000 by itself is a good subwoofer and is definitely one that should be considered if space is a consideration. In my case, I should have gone with the 6000 or even 8000 model to get the volume I was looking for. However, I can and likely will get another 4000 which because of their size and performance, should make an excellent combination that I will ultimately be happier with than I would have been with a single SuperCube 6000. With the above stated, it gets 4 stars and not 5 because I found it to be harder than the previous 2 subwoofers to properly place in our living room and by itself doesn't meet my needs.

    I have used other subs in the past Velodyne, Polk etc... I have the Super Cube hooked up to an HK 3700 A/V receiver in an open floor plan living room. (40 x 37) area. Visually the sub looks so tiny in such a large space and the hi gloss finish is beautiful (girl friend approved). The sound quality is great. It is smooth and deep. It can rattle the furniture with the correct incentive (movie), but it is also very detailed and gives the sound of the other speakers a "full bodied" or fleshed out quality that was missing with out the SuperCube.

    I purchased the SC4000 after I tried the SC2000 with the def tech 8060 front speakers. This speaker is better matched with the 8060 speakers. I need to try more movies and music to tune it a bit more but at initial setup with the Yamaha YPAO auto setup it is musically seamless integration with the 8060. Can't wait to really turn it up to see how much I can feel the bass when watching a movie. For the price this is a great middle ground of the def tech subs and the size is perfect. All their subs are great for their size.

    I bought this as a 2nd sub because of its size (and listed capabilities) to place in a corner to balance the bass in my room. To a casual listener it sounds great and digs pretty deep— especially in the corner, but with more critical listening you realize how boomy it is. I’m not a fan of boomy subs, so I returned this and got an SB-2000 instead. It’s bigger but so much better. Still like the sub over all though, it just wasn’t right for my specific use case
