Impressed!

I’ve had the sub in for about a week now and without fine tuning the amp I am impressed with the sub. This thing hits hard and clean, especially for a sub that only costs roughly $250. I look forward to getting everything dialed in and to see what the sub is really capable of.

Alpine 10” R Series

I highly recommend this subwoofer. I have it powered by a jx1000/1d in a ported fox box for my ram pickup and the sound is amazing for 1 sub.

Flawless bass

In a 0.4 cf sealed enclosure, powed by a Fosgate R500x1d making 630 RMS @ 2 ohms. It sounds incredible.

Alpine R-W10D4

I have mine wired to two ohms on 675 rms in a porter box under the back seat of my truck and it kicks ass!!! Makes my mirrors shake and my change quake! Not a competition sub like a dc or fi etc but it’s def a top-notch everyday consumer sub.

Great as always!

Great product, outdoes all other subs in the price range ive had several cvx 10's that just dont do what the alpine swr10d4 would do. I got the new updated model at the same price of the swr10. Pounds extremely hard out of a 1.25 cubic ft ported box at 37hz. Running off a LOC factory headunit 08 saturn astra. It does what i wanted it to do and then some. Could easily take more than the 600w rms at 2ohms my kicker amp is giving it.

Well this was my second one

I liked the sub but did not last very long I had the same sub but the 2ohm voice coils had that for 6 months then white spots showed up on the center found out it was faulty so I traded it out for this sub. But this one only lasted 3 months. Took it to 2 stereo shops and was told my setting were fine for the set up I had all Brand new deck and wires and everything. And the white spots are back again.

New Type R

Running this sub through a PDX 600 watt RMS amp. I went straight from the last model Type R 10 to this one, same box even. Bass is tighter, seems a bit louder, happy with my purchase. If you are considering this sub, on a super tight budget, it's worth the extra $40 over leftover prior models.

Better than the last Type R

This one sounds better than the last Type R i had several years ago. The build quality was much better, Sounds amazing for the price.
