    MUCH better quality than the price implies

    I have read quite a few reviews on here where people said that the sub blew or wasn't loud enough so they took it right back, etc. I recently purchased the DXi 12 DVC from Best buy and paired it with a Polk Audio PA 880 amp. The sub is wired to 2 ohms. The power wire is 4 gauge and the speaker wire is 12 gauge. I custom built a ported box to Polk's exact dimensions. I have played it at a moderate level for almost 35 hours and am just starting to crank it up. The quality of the sound is amazing! It is an extremely clean sounding and hard hitting sub. It is also insanely loud for a budget 12. Just remember..... Instructions are your friend!!! Too many people either 1) have the wrong size box, 2) have the wrong size speaker and/or power and ground wire, 3) crank it to 100% right off the bat without allowing a break-in period, 4) grossly under power it or a combination of the four. My system sounds better than my buddy who just had his setup installed consisting of a JL Audio 500.1 with 2) 10w3 in a sealed box. When it is all said and done, read reviews from many different sources and take all of the information into consideration. Basically, consider the source. You really can't go wrong for the money.

    Perfect Sub For The Price

    Posted

    Got a package deal discount when I bought this sub with a vented enclosure. For the price I paid, it's perfect. Even with a very underpowered amp I bought elsewhere, it hits hard and delivers deep rumbles. Dual voice coil is a nice bonus. For the price, it has a high RMS power rating (about 350 watts at 4 ohms). Make sure to get a nice box to accommodate the sub, or else you lose out on the sub's overall potential. I looked at Kicker, almost bought a Kicker but at the same price the Kicker was half the RMS power. Price/Performance ratio is excellent.

    I bought this unheard based on good reviews and a blow-out price from Best Buy that made it irresistible. I'm not disappointed at all. Mounting was difficult because the included screw heads fit flush into the counterbored holes of the speaker rim and no misalignment is tolerable - gotta be straight and centered. It makes swapping this woofer for an older one tough if your old holes are slightly crooked or off-center. The end result looks very nice though. I replaced a 10y/o RF Solobaric SVC and the Polk sounds every bit as good and loud given same power. Although the power rating is relatively low, the smaller-than-expected magnet reflects that. An unadvertised bonus - this woofer is marine rated per the box. Overall, I'm very happy with it.

    For $27 total this sub could not be beat i had another sub that was a DVC which i bought used and i had found out that one of the Voice Coils were bad in it so i had to get a new sub, and since the this store did not have any Bass Lines in stock this was my 2nd choice. I tested this sub out at the store and it was in the box i use all the time a bandpass box so i got to test it in my favorite box, and the amp they had hooked up to it was about the same amount of power i was using and the sub sounded great! One thing i did not like was the speaker terminals, normally you would find a dual set on each side but this sub only comes with 1 pair on each side making it so you half to do a lil different wiring!

    I picked this sub up for $39.99 it was on sale, infact I wish it still was I would gladly buy another. This sub BOOMS, It sounds better then some rockford fosgate Punch subs I had previously. The bass is clean and loud, no distortion at all. You can run this sub at 2ohms by hooking up the voice coils in parallel which I liked. Polk has great customer support as well, they will walk you through how to build a box if thats what you choose to do. Again, if it were still on sale I would gladly buy another, infact if I had the money I'd buy it not on sale because I like it that much.

    Great Sub For Money If Set Up Correctly

    So many people are saying and have told me this sub sucks and is constantly blowing. This sub is one that NEEDS to be warmed up and not immediately put on full blast. I have 2 Polk Audio DXI 124 DVC hooked up to a Hifonics BRX1100.1D which cost me about $200 after the warranty was added. It gives each sub the proper amount of power and doesnt over-work them. Last year i had a single Polk Audio DXI 124 DVC and blew it in a few months because i had it hooked to a random amp and didn't break it in. This is an amazing sub when broken in and properly equipped so for only $100 you're getting an amazing sub.

    Bought htis as a Deal of the Day for $29, when the actual retail was $99 and I was impressed with the quality of this speaker regardless of price. at 360 RMS, I dont even have enough power to push this 12" sub.....yet :-) but it worked well with 100 watts from a kicker amp. Takes a bit of knowledge and trail and error to get the correct box size and port but as for the speaker itself, I would highly recomend this Polk Audio sub. The chrome emblem on the cone looks great, and the deep powerfull bass you get from this speaker will not dissappoint at $29 or $99 !!

    I always build the biggest box I can fit in my application, for my subwoofers and I always go with a sealed box. This is the first woofer I've bought were that didn't work out. So I ported the box with piece of 3" pipe. Wow what a difference! Sounds so much better. The paperwork recommends 0.88 cu ft Of air space, I guess if your going to go with a sealed box you should stick to the manufacturer's specs. Overall this sub sounds great for the price I paid, got it on sale. It hits just as hard or harder than the two Sony 10's I had before.

    I had one in a pre fab sealed box and it was pretty good. Pleased but still felt it was missing. I talked with a Geek Squad auto tech and he recommended a custom enclosure. He provided me all the info I would need for me to build it myself since his store is not equipped to build custom enclosures. I went home to build the box with the info I was provided and it came alive. For only having a 300 watt RMS sub on 350 watts it sounds great. It cover all frequencies needed.

    Custom built a center console sealed box (1.1 Cu. ft.) for this sub and powered with a 1000 W. Kenwood monoblock. Sounds great and plenty loud for my taste, as i only put in vehicle because bass response in my pickup was weak. I dont listen loud and like to try to blow windows out, only loud enough to hear full range. This sub more than adequately fills the gap, especially for the price (49.99). Currently running it at 2 ohms as it is dual voice coil. Works great!

    I purchased a single 12" dual voice coil and matched it with the Polk 400 amp. I built a custom sub enclosure(MDF) based on the spec's from polk and encapsulated the enclosure with fiberglass resin to waterproof it for use in an old jeep. All I can say is it blows me away!! Clean tight and powerful. $250 sent for amp and sub - Nothing come close for that price!!!!

    I've replaced my car's previous system w/POLK AUDIO subs & speakers!! I initially bought 3 1/2 in. Polk Audio dash speakers and they blew away my RF 6 1/2 in. door speakers with there awesome crisp, clear sound! So now every speak & sub I own is & will always remain POLK AUDIO! Oh, and when you buy P.A. speakers they include heavy duty, cool-looking installation wiring. (Unlike others...)

    Great sound for only $30 on sale.

    So i originally had 2 12" Gravity 600w each with a 1200 watt amp. It was great but i wanted to sound more boom. So i purchased this sub for only $30 when it was on sale. I regret not getting 2. Now its $99.99. One of the best subs i have had so far. When it goes on sales again most def im getting another one. If you want loud sound bass this is it. But you also need to have a amp to push out well.

    Good sub for the price but after getting it it didn't have quite the quality for the price i was after. Have had polk audio speakers in the past and i loved them but this sub didn't met my expectations so i took it back to the store. Ended up going with a different brand for the sub.

    these speakers were a birthday gift to my husband and he totally loved them, I thought he may not like them because they were not name brand but he was really pleased with then, he loved the way they sound, the way they looked the style of them, so thanks, Best Buy,

    Easy installation, sounded great until I cranked up the volume. Music lasted for two days, then the sound went out. Had it replaced with a new speaker of a different brand. Root cause of the problem...soldering connection broke, disengaging the power to the cone.

    I purchased two of these and installed them in a small car they are totally awesome there really nice for the price. I have pushed them pretty hard and have not blown or hurt them so far. Overall reccomend these if you want a clean bass sound on a budget.
