It isn't just specs though. What company are you looking at? Or did I miss the brandname somewhere in your post?

Okay, by looking at your other posts I'm guessing you are looking at the ICBM 5712DX Specifications on http://www.homestead.com/prosites-allmanmusic/performancetek.html The Volfenhag speakers are similar in design. Have you checked those out? I'm not familiar with Peformace Tekniques but from I've found at other places is that the speakers are discontinued. Here's is a positive review from a site that used to sell them. Keep in mind the review may be positive just to sell the item. . . .

Specs look OK. Depends what you are looking for. If you want to put them in a sealed box, a box volume of 2 cu. ft. will give you a total system Q of 0.8, which is about what I like. That'll give nice smooth bass with a cutoff frequency around 41 Hz. A 1 cu. ft box will give you a system Q of 0.92 which will be a little punchier and a cutoff frequency of 43 Hz.

what site was that review on and how can i find more?

and sure thing less section for one topic
