Alpine Type-R SWR-T12

Great subwoofer

This subwoofer has amazing bass for a shallow mount plus it's has a well built frame.

Great

Installed this in a custom sealed box in my 350z and it sounds great. I had the old, thicker 12" Type R and this sounds just as amazing. I even installed this in the worst location (the compartment behind the driver's side seat in the 350z) and it still sounds awesome. Can't even beat the price anywhere else.

Blows easy

I bought this subwoofer a year ago and put it in my truck with the alpine pdx-m6. Both units run at 600w rms and I somehow blew the sub the same night. Granted my wiring might have been the problem. I then upgraded some wires and got another one. (No warranty) this then sounded great and was honestly a wonderful sub! I had it in a down firing box under my seat and if you stood outside of the truck you couldn't hear any obnoxious bass. But inside the truck everything vibrated crazy! But then it blew randomly one night at sonic, without being turned up. These shallow mount subwoofers aren't able to take the abuse as a regular subwoofer and although it sounds good the reliability isn't there.

Good sub

I had this sub installed in a 06 f150 supercrew under my back seat. This is a good sub and it sounded great. However for the price(currently 309.00) and the single voice coil config, I would recommend something else. I currently own a 2011 supercrew f150 and for the price of 1 of these subs, I was able to purchase 2 skar audio vd-10(10") subwoofers and a box for under the back seat. I must say these 2 dvc 10" subs have more wiring options than the Alpine. They also blow the single 12" away. Using an online port calculator I ported my current enclosure to around 35 hz and they sound incredible. They shake my truck like the Alpine never could. The point I am trying to make is that while Alpine has a great product, I believe that for the price, there are a lot more options out there. All it take is some patience and a little research.

Nice lil sub

Very happy with this product. Good for small spaces and surprisingly loud. Could not really fault this product. Perfect for what I wanted.

Love it

Love this woofer.

Solid Sub

Bought this sub to go in my truck due to lack of space. I have had Type R 12"s before and they sounded great. Props to Alpine for getting it right on the shallow mount. I have heard several shallows, and none compare. Just one in a small box hits pretty hard, it won't blow your mind but its a good sub. I would not pay what other places charge for this woofer, some up to 500, but for what its listed for here its a great deal when space is an issue. I will say the box and power are very important. I had it in a .4 cubic foot box and it sounded terrible, switched to a .75 box and it made a world of difference. Give it at least 500 watts rms too, trust me it needs it. Also, make sure to get a grill, although its constructed very well the cone will take dents very easily.

Great but be careful

Had these in a sealed box, the box cracked and they took some damage from that but they played on. Both blew about 6 months after owning them of hard playing. Ordered 2 more now if these blow again ill probably switch To something different but overall i like em. They hit hard enough for shallows. I have them wired to 2.3 ohm in series. They dont drop as much as they should and so they dont get as much power from my amp as they should. This brand new one i just got rattles when it plays already. But still plays fine.

Very clean bass

I am very pleased with the performance of this sub. I was skeptical about how good it would sound compared to a regular 12" and it totally exceeded my expectations. I am running it with an '10 Apline PDX M6. I built the enclosure to manufacturers volume recommendations and it's perfect.
I had to custom build a funky shaped box to fit behind the back seats of my '09 Tacoma double cab. I went to a few car audio shows and have by far the highest SPL Tacoma in Edmonton with an OEM style system (no huge box in the cab)

As long as your enclosure volume is correct you will love this sub.

Great shallow sub!!

I bought this sub to go in my 08 Tundra. When I started my audio build I initially went with the Rockford P3 10' shallow sub, then upgraded to the P3 12', and finally to this sub. This sound undoubtibly sounds better that both of the previous subs, it will really handle the lows alot better than I expected. And right now I only have and MRP 500 pushing it. I am not even sure I will upgrade the amp it just sounds and pounds so good now. It is a little $ but you get what you pay for, and out of all the shallow subs I have heard this one is the cleanest, tightest, most accurate I have heard.
