i simmed a ~250 liter cab with 96 db @1pi@2.83v,f3 20 hz.
dont know how low jou want to go but 20 hz f3 looks a good compromise fot ht and music.
nice speaker btw

Parameters put into HR==> T-TQWT using 2 drivers:

20hz good compromise for HT and music? Isn't that pretty much a HT sub?

Watch it guys, the 12B100/R has a very limiting Xmax that is not practical for <35Hz use...
If you want to go below that use the 15B100/R (both are JBL copies btw).

I know that they not are any monster, but for a small ht it's better than a small Jamo sub.

I'm not sure jbl copied beyma, i think beyma produced some of jbl's driver.

THank you epa and bjorno!

Hi Mats,

Agree, Here is another well thought trough design using the Beyma 12B100RE driver that is IME easy to fold:

Like the T-TQWT this OD-QWP is IMO loud enough for use in a normal domestic room.

When placed near a corner the in-band SPL would exceed 120 dB with a margin.
