    I think the Rockville subs are under rated, I have invested in them more than once, and have gotten good results. They take a pounding and with no issues. STAY WHITEN THE SPECS'S !! Like anything, if used with responsibility, you get the results your looking for.

    Amazing sub

    I installed this sub and was immediately impressed. I thought I would be let down like I was with other brands budget line subwoofers. This subwoofer sounds amazing, hits hard and is extremely loud. One subwoofer is as loud as all 4 that I had installed last season. Great investment and highly recommended

    Good Value for the Money.....Maybe...

    Good looking build quality, at least surface level...i want to like this subwoofer, it sounds good and it gets down, but the particular W12K9D2 12" subwoofer i recieved is a supposed second reversion but i can't play it at any power, let alone rms power without smelling voice coil, they haven't blown or anything yet, but i constantly have to take it way easier on these than the specs would suggest, i figure with the voice coil smell, it's just a matter of time. At First i thought (or hoped) that maybe it was the new glue choice had to burn off, or was maybe over glued and had a burn off smell... probably wishful thinking, so they've lasted 3 weeks now hooked up...i don't have high hopes though... not sure what the exchange/return policy is on these. I've heard that rockville stands behind ...

  • One hell of a gnarly bad-ass sub!!

    The sub came at least a day earlier than I expected....I pulled that heavy monster out of the double shipping boxes and immediate I could tell this was one serious monster...I guess the 11 lbs. Magnet was the first clue....I loaded it into my 1.5 cubic foot t-line vented box( tight fit cuz box wasn't quite cut out for that large of a diameter sub- some modification required ....no biggie...) popped in some godsmack, and turned up the volume to about 8 and realized this thing POUNDS!! Let me tell u....the difference was amazing....I was running a little power acoustic 800 watt crypt subwoofer b4 @ around 600 watts @2 ohms and it was pretty loud...but running the Rockville @ 1 ohm and closer to 1200 watts was like night and day!! This speaker hit almost twice as hard at probably half the ...

  • The sub is loud but not sure about longevity

    The k9 12 sounds good and its decently loud. sadly I have not got much use out of it so far, there's a ticking noise under the dustcap. I would only run at most 630rms to this sub. No other complaints
