TL
Just a basic straight TL,
tube length 40 inches
Area 48 sq, in.
Vent at the bottom, 2.5 in diam. (still playing with the length - at this time around 4 in.)
Center of driver at 10 inches from top of line.
My tube (square) is folded 90 degree at 30 inches from the ground (like an inverted L, the long side being around 30 in. and the short part around 10 in.). The driver is mounted at the top of the cabinet, right in the L corner. and the area behind the driver (roughly 6 x 8 x 10) is stuffed, while the lower cavity is split in two in the middle, with light stuffing in the tiop part and no stuffing on the bottom.
Bass is overwhelming, and I am still debating if this is real bass or not. The bass character is quite lean in the upper range with no chestiness added to male voices. But when playing electrolounge, drum&bass (and even double bass jazz) the windows rattle and I feel sick in the stomach (OK OK, it's really not THAT bad).
I have no way to measure the exact cut-off, but let's just say my sub just does not have any outpout any lower than the TL, when low passed at the lowest Xover point, 40 hz.
This is quite amazing considering the fact that a 4 in. driver can pretty much do the same (or even better) than a 12 in. dedicated bass driver...
