Great all around for me

I love the plastic surround protecting the middle/outside part of the speaker that goes up and down. I have it placed in the spare tire area with the cover on and the speaker/sub is protected. I tried a skar and power acoustic gothic. the gothic and the skar has the ruber surround cone that goes up and down about an inch... to much for my design need. Skar was great all around. the gothic is VERY hard hitting! I find that the Pioneer is great for all around, I can listen to my classic rock, my wifes Alantis rock(ish) and my son can about destroy my mirrors with vibration with his rap type(not sure what to call it very heavy bass) music. Great sub for the daily driving not sure about comp type use. hope this helps... forgot about the sound storm that I would get again too its comparable to the pioneer I was able to keep the spare and jack lots of room 21 forester

100 hz and 22 hz hits for under $100.

Had the 400 rms TS- 250D4 in a sealed 1.45 cu ft box with 400 watts pushing it. Clocked at 114 db volume on stereo at 95% This guy in same box with 500 rms at 2 ohm clocked 130db stereo at 70% volume. Hits 22 hz well in a slightly oversized sealed box. If you got the D2 to 1 ohm and ported box, i doubt your review mirror stays attached to windshield.
