Usually when I see a full 5-star rating I think it's just a fan boy who doesn't really know what he's talking about. This is an exception.
*Value* - $200 for 1000watts? That's incredible
*Design* - Dead sexy. Perfect with black interior.
*Durability* - Very strong. See below.
*Features* - Included jumper cables and connections - very convenient to wire the sub to its final ohm rating.
*Ease of use* - Manual is very descriptive and includes diagrams of all the different wiring options. Wiring the jumper cables and the speaker connections to the amp was very easy.
This woofer was a huge upgrade for me. I went from 2 DUAL 12" in the rather large, flashy bandpass enclosure of theirs to this Alpine sub in a Sound Ordnance ported box. I've got a Hifonics Brutus 1200.1 powering it at 2ohms.
While I'm still breaking it in and tweaking some settings with the tuning, I have to say I'm very happy with it. With my bass knob, I can dial it down and get very clean, subtle bass perfect for really any genre. Upon cranking it up, it hits *very* hard and I soon forgot I only had one 12" in my hatch.
It seems to keep at a low temperature, and I have my gains and bass boosts set pretty conservatively. I tuned my amp with a multimeter to reach the desired voltage. It looks amazing--huge upgrade, in my opinion, from the older type R's. Flexes well, no noise, etc. I do sometimes smell the woofer at high levels, but I think it's just being broken in (with the DUAL's I learned what voice coils smell like). Also, that magnet is *heavy* and this thing is tough.
Overall, if you want a sub that hits very hard cleanly, or one that cleans up and compliments the mix, this is perfect.
