Lambda TD12s T-Line?

akunec · 11th July 2005, 05:04 AM

Would it be possible to put a lambda TD12s in a Transmission line, tuned to ~40hz or so?

Heres a link to its T-S parameters:

But would it be practical? I need a reasonable size and look and im not sure how large the Tline will be.

The enclosure is not small (tuned to Fs=31.5hz)...

Width: 48"
Height: 57"
Depth: 13.5"

Transmission Line inner dimensions:
(straight, single-fold, two lines)

Width: 12"
Height: 44.5"
Depth: 23"

Fibreglas stuffing: 1/2 lb/cu ft

Regards
Joe

Actually, with such a large line, the driver could be placed into (be part of) the line -- reducing the height to 46" (from 57")...

Thanks for the help guys. Those dimensions are much too large for my application. Looks like I'll have to go ported. I need at most 25"*20"*30".
