Thank you for the welcome I listen to metal, rap, hard rock, alternative, trance(mostly progressive), r&b. SQ matters a lot to me...but I'm a basshead and want to be able to feel the bass pounding in my lungs when I want. Whenever I look at a sub I make sure it can hit atleast 20Hz if not 16 Hz. But it looks like I will have to compromise in car audio as those subs usually need a much bigger box than the 2 cu ft that I want to limit my box to. So I would like the bass to be atleast 30Hz or below at -3dB. But will compromise more if I realllly need to. I have a Pioneer Premier PRS-X720 amp. It's rated at 400W RMS @ 4 ohm but its birthsheet has it rated at a little over 800@ RMS @ 4 ohm. It is very common for the amp to have double its rated output. I don't want to run the amp at max so I'm trying to limit the wattage I use to 700. My budget...well for the time being I'm trying to spend less than $200 on the sub and I dunno $50 on a box. I want a 12" sub...I don't have the room for a 15". I spent a lot of time on sounddomain, elite car audio, car audio, and car audio forums gathering information. The subs I considered are: IDMAX OZ Audio Matrix Elite Resonant Engineering SE Infinity Perfect 12.1 Dayton MKIII Dayton High Fidelity Elemental Designs OV line W3 Alpine Type R Kicker Comp O Audio TC2+ HSU ASW-1203 Soundsplinter rl-p The subs I am still considering: Dayton MKIII Dayton High Fidelity Soundsplinter rl-p IDMAX OZ ME Alpine Type R I am leaning heavily towards the Dayton HF...but slowly but surely going to the rl-p. I'm a very number based persons as I can't really hear the subs and 97% of the people I've talked to haven't heard the Daytons... I'm hoping to find someone that has heard the Dayton MKIII and/or HF AND the rl-p. That will help me make my decision a great deal.
