OFCCM, go for it.
Adire's Tempest combined with DT 300 will kick some serious butt. For those have not yet visited
www.adireaudio.com , here's a quote from them.
"With over 2.5L of displacement capability, Tempest can reach over 103 dB SPL at 20 Hz, in a sealed box. It can reach 108 dB SPL @ 25 Hz, in a sealed box. That's above home theater reference levels! And placed in a vented box, it can reach even higher SPLs (easily above 115 dB SPL anechoic from 20 Hz and up. In room, expect peak levels well in excess of 120 dB SPL)"
How much would you have to pay to get that kind of sub from other brands? Now that you've been told about Adire, it will be too much.
If you listen to music 80% of time or more, get a sealed enclosure. If its 50 / 50 between HT and music, I'd say ported enclosure or a large sealed one like 5 cubic feet or more (if you have room for it).
I could go on and repeat the comments written by happy consumers of Adire products but my time is limited so I'll recommend this site in case you haven't been there. This is where I first heard about Adire Audio:
http://www.audioreview.com/pscSpeakers/Subwoofers/Adire,Audio,Tempest/PRD_125237_ 2741crx.aspx Adire and Outlaw Audio have something in common. They are both small companies that provide incredible value.
OFCCM, one more thing, I'm not sure if this is Adire's sister website or not but they carry some fine looking Adire subs if you are concerned about the finishes.
