It goes from a solid low end to shaking the windows in volume all while keeping a clear sound

There is no frequency noise or static or fuzz sound when it comes to the actual sound of the speaker

Has great sound easy to hook up, work nice with my dj setup.

Extremely loud and good quality sound

Decent sound for the price.

Good sound, great price!!

so I went with the Galaxy with it's 5" array design and have a nice sounding system for cheap

Good sound

I use it under a Roland KC 110 stereo amp mounted on a sub pole, and the sound is amazing

Great sound

I really like it, the subwoofer gives out an excellent sounds.

Way to go Rockville, very inexpensive, good sound and reliable

After plugging in the explosive sound started immediately

I have also found with my background in electonics and sound that you can "Line X" the boxes for a better sound

Sub sounds amazing with my rockville rgb15bt pa speakers

My sound was sooooo much better than it had been

it so heavy.i have yamaha 300 watt subwoofer,the sound very good when i select signal or i turn off power ampl

Adds great sound when your drivers need a little more thump.

Hap to play around with settings to get the right sound

I just dont like the sound of their little 2" multiple array speakers

,THE SOUND IS AWESOME, MORE THAN SATISFIED WITH IT !!

The Sub sounds great really added alot of bass to my 15in pa system

I have gigs to do, missed one, and sound is very important to get future bookings

The sound is still pretty good with the RCA jacks.

GOOOOOD SUB NICE CLEAR SOUND

Amazing sound !

AMAZING PRICE.Crisp Clear Sound, Deep

Speaker have a good thump sounding bass

Amazing sound and this sub is a beast, it shook the ceiling tiles in my house and it wasn't even turned half way up!

Well, the Behringers are going back into the box this week due to their poor sound... but lo and behold, the budget Rockville 12" subwoofer rocks!

For BEST sound I'd suggest using XLR from the Sub to your Tops, IF they are XLR.

The speakers were fine as far as the sound

Amazing sound in such a small and light package

Very good sound and perfect bass!

Very pleased with my rbg12s ...Makes my JBL 15 inch mains sound twice as big..excellent product

So I highly recommend this subwoofer if you on a budget and want a good sounding subwoofer.
