Go off the Richter Scale with DBXi Subwoofers

The DBXI-15D Dual 4 ohm 15" subwoofer is the perfect example of what it means to carry the Earthquake Sound name. Earthquake Sound subwoofers need to not only be loud but also sound great and perform without any problems. With an RMS of 750 watts this woofer will produce enough bass to really satisfy those low-frequency reproduction needs. The woofer features a pressed pulp fiber woofer cone and high-roll rubber surround for added stiffness, rigidity, and higher excursion capabilities. Its turbo propped cooling reduces thermal heat and thus increases output and lowering distortion during all periods of play. The woofer also features a 2" voice coil and double stacked magnet structure able to produce an impressive 3.5" of linear excursion, giving you deep impact bass. The DBXi woofer is your everyday driver that will perform day in and day out without compromising quality.

this sub could handle any amount of power I put into it

Wow this sub hits harder them any single subwoofer I have ever heard. I had this hooked up to a Boss ce3500 watt amp. Not much else to say besides earth shattering base.

Cons: ear damage

Pros: 5 year warranty.

deep bass

This thing blew my mind. I have it in a 6 cf box that I built @ around 25 hertz paired with a hifonics brx 1600.1d and my 1 15 gets lower than my friends 2 ssa 12s..bottom line is this woofer is easily as good as woofers that are twice the price. Save yourself some money and just buy this beast

OMG. i found what i like

pros giving two of these things 450 watts each very loud. excursion is actually 30.48 mm xmax.. super low lows . respectable highs and earth shaking bass only with 900 watts on 2. also got a ported box here to . works perfect if you invert them. Sonic Sub Box: 2SV15 (Black. i got some air moving . i listen to rap and dub step. sound amazing . Highly recomend this sub. looks and feel and sounds high quality con i tryed rock and they were not great. Con made in china

best $230 ive spent

I love this sub. It produces unbelievable amounts of deep bass. For comparison I have a 18 inch tc sounds Lms 5400 in a sealed box and the earthquake can produce deep bass almost as loud at 1000 w. I wouldn't have bought the tc 18, if it weren't for the fact that it can take four times the power and sounds amazing. I had a large ported box sitting around ( 3.5 cu.ft. plus a 2.5 by 16 by 36 inch long slot port). I highly recommend this sub in a ported box tuned to around 25 hz. I run 750w rms to this sub for hours on end and it is still going strong.

Earthquake!

I have owned this sub for a month now and its a beast! The loudest single sub setup i have ever heard. It hits lows crazy hard, it even broke my rear view mirror off haha. If you are looking for a low bass monster, look no further!

These were OK

Doesn't get as low as I like it to. Also barely powering them with my 3500 block amplifier on a short trip and they both burned up. Need a recone kit.
