The 3512-04 is a 12" single voice coil, 4 ohm, 250 watt Car Audio Subwoofer designed to deliver outstanding SPL and sound quality in an affordable combination of state-of-the-art MTX sub features...and it rocks.
This subwoofer features the MTX Inverted Apex Surround. This is a departure from a traditional half roll surround. The Inverted Apex is narrower thereby increasing the surface diameter of the subwoofer cone enabling it to displace more air and generate higher SPL. The 55's are designed with a progressive suspension that lowers distortion resulting in improved sound quality even at high volume. 35 Series subwoofers are ideal for improving the sound in any vehicle. Their low profile does not require a large enclosure so they are perfect for most vehicles.

Well made
Put 2 of these in a slim box in an 05 Ram 1500 standard cab powered by an Alpine PDX-V9 and they sound great. I almost always look at reviews first but at the time there were none for this specific model, and still aren't. Sonic got them to me fast! Build quality was very nice. Stamped steel baskets and heavy duty connecting posts made wiring a snap.
Something worth noting on this specific model is that the cutout is a little oversized so for a pre-made box you might have to trim a little for fitment.
I have used MTX drivers,mids, and subs many times over the last 20 years and have never been disappointed. This is no exception to that. They do not hit the really low frequencies but I suspect that is more of a box fail than a speaker issue. It is a slim mount after all too.
If I had it to buy again would I buy the same ones? Yes, I would.

Just the box
The sub itself was in perfect condition. I can't say that it would be the same case for all but this one was perfect.
