Just a FYI for ya'll, got an Orion H2 10 inch a few months ago and finally got it (well they screwed up on shippin and it took a while to get the right one) I got the 10.2 model and am powering it with a Hifonics Brutus 1500d at one ohm so the sub is (supposidly) getting 1500x1. Good deal and I would recommend CBRstereo.com, although they did ship the wrong one, a 10.4 when I ordered a 10.2 but they did make it right and their prices are good; Orion H2 10" Subwoofer
List Price $549.00
Your Price $199.00
Orion H2 12" Subwoofer
List Price $649.00
Your Price $279.00
Orion H2 15" Subwoofer
List Price $749.00
Your Price $329.00
So, just passing on some info, I think these are pretty good subs from what I have read on here and I am really pleased with this 10 inch, I replaced my big 15 incher with this one and have it behind the driver seat in my Blazer, it not only gives me more room in the cargo area I can now get a great "back massage" with the Orion right behind me!!!
