Great 10" sub hits hard

I have this sub with a kenwood KAC-9105D amp 900w rms at 2 ohms. I've had it for a month now, and just now the sub is starting to break in and is sounding better every day. I was worried about the distortion at first but it seems to be clearing up...I wonder if anyone else has had issues with this. It seems as though it shouldn't waffle or distort being 1000w rms and 3000 peak. But it truly sounds a lot better now than at first maybe it was just break in period. Sonix got all the deals and I won't shop anywhere else.

Best speaker i have owned

I would recommend loud as hell and i only have one 10" in a probox. Only bad thing is that it smells funny for the first couple of months when u push it, but after that either you don't notice or u get use to the smell better than kicker punch and JL audio i have owned them all.

amazing sound quality for the money

wow for a 10 in sub you cant go wrong. i have just 1 in a ported box tuned to 32 htz, custom made with 1.5 in mdf all around running on a hifonic bxi2010 with about less than 3/4 gain. perfect combination the sub is getting about 900 watts rms it could handle alot more but i cant handle the madness of the bass that why it is set there. nice clean bass with no distortion and the low notes i just can't describe just amazing beating the crap out of my 07 nissan quest. sonicelectroix is the store to beat great prices on everything.

Sound good but be careful

I have had these 2 of these subs for a week now. They do have excellent sound quality if put in the correct box. I have them in a dual 10" separately sealed box. With 1.25 cubic feet per. They sound very nice. Problem is i have them running on a Rockford Fosgate T-2500bdcp. I do have the gain turned way down. I had everything professionally installed or so i thought. After two weeks of playing them easy to break in 1 blew at a fairly low level. I didnt have in bumping. Just heard a crack then pop. Boom sub is gone. I am going to replace it with another but turn gain down even farther. All in all i do recommend them but make sure you properly power them. Use SMD products to watch clipping. Be easy on them for awhile and you should be good. I listen to mainly metal music death, black, and industrial metal. They kept up with the double bass drum beautifly. Try them.

Upgrade from Walmart Brand

Upgraded From 2 12' Dual Subwoofers in a bandpass box with Dual 300W RMS Amp, to 1 Of these in a 1.3^ft Ported Box bought here on sonic Powered by a Alpine MRX-M100, 1000W RMS Amp. This Subwoofer is Considerably louder then my Old Setup, Takes up 1/2 of the trunk space of my old setup, and the sound quality of the Old setup isn't even comparable. Amazing Product for sure.

1 TYPE-X vs 2 CVX

I have just pulled out 2 kicker CVX 10's out of my car to get ONE of these.... and as skeptical I was about losing even a single measure of wattage, I didn't.... I have 1 of these 10s in a sealed PROBOX pushed by a kicker zx1000.1 at half way gain on amp, and my scion TC rattles from front to back like some 15 is inside. AMAZING SUB and best of all VERY affordable

Great sub and small space

I had one of these in a 1989 Subaru GL wagon with a band pass box with 1500 watts to it and it beat my car up. Had to buy a new car cause a lot of stuff broke from the bass. Great little sub.

Type X 10

I have this sub, and it is amazing!!!! I am currently under powering this sub with a US Amps Merlin MD1 1200. It only gives me 600 rms @ 2 ohms, but i have to say that it still bangs!!!! Currently changing my stereo and am leaning toward the Hifonics hfi 1500d. This should push the sub nicely. I ordered a new larger box from Sonic and waiting on it to arrive. Ordered my Hifonics hfi 55.4 today and the big boy will be will be ordered soon. Still trying to decide on the highs and mids.

Alpine SWX-1043D

I have this sub in a custom ported enclosure hooked up with a JBL GTO 14001. For a 10" subwoofer it hits hard! I didn't expect that much. Plus it's a good deal, for this price you get 1000RMS of pure clear bass. The only cons I have is the depth of the sub if you have limited space, the magnet is big, otherwise I highly recommend this subwoofer, you can't go wrong!
