Alpine SWR-10D4 Type-R 10" Subwoofer with Dual 4-ohm Voice Coils (Each)

Love this sub. I had 2 before and they deff impressed me then and this does now. It is in a small sealed box to fit in an s2000 in the storage area of the trunk. Had a rockford hx2 12 before in a standard wedge box. And this is louder and deff more clear on the same amo. Have a bigger amp coming tomorrow with 4 Guage kit to wire it. May port and if I do I will update with both amp and box outcomes.

For the price they cannot be beaten. I think Sundown must be promoting themselves as Ive seen multiple mentions. Ive been using Type Rs for 10 years in air tight sealed enclosures. Accuracy and power handling cannot be beaten at this price or much higher. If installed correctly look forward to extremely detailed bass. Not really the sub for a big Boom, but if you car about every note in your music this is the way to go. FYI watch out for "grey" or "B" market subs. A&A online sold one to me then following the complaint of random glue drops and missing serial numbers the dosged every return (even exchange) that they could. May have to purchase another to replace that one. STORE REVIEW ARE IMPORTANT.

Purchased this as part of a full car audio system about a year ago. It is paired with an alpine 1100 w mono amp. 6 months in the cone tore away from the surround. While this is frustrating, the seller (Coast2coast audio/now Royal Audio) swapped it out without issue. The sound quality is outstanding and it puts out a LOT of sound for a little 10" sub, it's much louder than most 12"s I've had! I'd purchase it again in a heartbeat!!

Had it for one day in a sealed box (.69 cubic feet) running on an MRP-1000 at 2 ohms. Sub died after 30 min of moderate use. It was probably just this sub, but I won't be buying another alpine sub ever again. They don't seem to be able to guarantee that their subs can actually handle the rated RMS power. I had more luck with a sony explode when I was a teenager than with this thing. This is what I get for cheating on sundown.

4 star subs. They look and feel a lot Better then they actually perform. From a durability stand point these woofers are horrible. Don't take much of a beating. SQ wise they're ok, they do dig pretty deep and get loud but the coils heat up quick and I'm only pushing half it's RMS rating CLEANLY in a proper sealed box. JL 500/1v2 is my amp. Can Barely hear it. Your gonna wanna go ported but I stay stray from Alpine for $140 and get something else. (RF P3, SA E-series)

Quit working less than 2 weeks. Didn't burn up, just quit. Sent it back got a full refund, but cost me almost $50 to ship back. Got a sundown to replace it and it seem to be holding up. It shakes the hell out of my son's Full size Bronco. Hurts my ears it hits so hard and low.

Everything was all good till somehow it cracked. Is this even fixable?

GREAT BUY!! I've got 2 just, installed in a Trailblazer SS. Sealed custom box. Went from kicker cvr's to these. What a world of difference. The base is deep and the range is great. Pushed by a 2400 watt Hifonics amp. Wired at 1 ohm parallel. Sound amazing especially for the price. Great for all kinds of music. I listen to rock mostly and these things sound great!! Great buy would definitely recommend these.
