Quick translation:
-Line length: 55"
-Top and bottom are 80 square inches
-Driver centre mounted 19.375" from the top of the enclosure
-Port mounted 40" from the top of the enclosure (that's quite a way up -no criticism BTW, just an interested observation, I've learned something new again, which is great!)
-Port dimensions: 3" wide x 1" deep.
-Stuff the cabinet with something like Dracon, 0.25 lbs to the cubic foot.
-Place a 2.25 Ohm resistor in the positive lead from the amp going to the speaker. Alternatively, you could just use a higher resistance speaker cable. Go for it -this is good!

Best
Scott

Or use SE tubes! =D
Is everyone working from TB's spec sheet or have you derived the T&S parameters? My pair are breaking in using a cabinet sized for the 657s and sound incredibly musical (if without bass) in the company of the above mentioned TBs and Jordans. Nice driver. Cold out of the box one measured an Fr of 75 Hz, the other 85 Hz. Just wondering what you're all finding.

Thx Joseph! I'm surprised but not at all displeased by the highish Qt. There may be hope for a semblance of bass after all. Thx again.

Actually, my bipolar towers (16L, tuned to 65 Hz) with the TB drivers have some very nice bass response. I was thinking about building a 6.5" bipolar TB subwoofer to go with the towers, but I don't feel the need to anymore. You may be suprised...
