Pros

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

    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!

    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!

    Sounds very nice...until it doesn't

    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

    Posted
    jlowest1980

    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.

    Fake Specs

    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.
