at 8 ohms... The box was enormous, though.
The Dbk for 10s is more moderate, but the box sounds decidedly better in the house than in the car-- I have a pair of them with Klipsch KV1089s in my living room-- they'll push 120dB+ on 50w each...
If this is one of your first experiences box-building, I always recommend sealed. The only foolproof box you can build. Ported is almost as easy to foul up as bandpass-- only when you botch the latter, it just sounds crappy-- and when you botch the former, you kill the speakers.
I would like to build a box like the death box, but sure won't be paying $10 for it. Is there any way I can get the plans from just downloading it somewhere else? I know a lot of people that has the plans that wouldn't mind sharing it right?
