If the QTs is around 0.30 yes!, you can use it in a TL IMHO perhaps others may shed more info for you as to other applications as I am not familiar with this driver...... cheers Tomcat

Hmm...that's pretty weird,

my parameters come from the lspCad Database, and they are NOT the same as the Focal homepage says...

Using Focal's specs, a ML-TL looks good:

T/S max flat:

rp = 2"
Lp = 5"
density = 0.4lbs/ft^3

L (in)
29.941

S0/SL (in^2)
78.491

S0/SL (width)
11.270

S0/SL (depth)
6.965

X0 (in)
12.228

Sd (in^2)
53.692

Qts
0.4234

Vas or Vb(ft^3)
1.36

Fs or Fb (Hz)
47.6

All dims inside
'rp' = radius of port
'Lp' = length of port
'XO' = centerline of driver down from top
width/depth are golden ratio suggestions, you can make your own based on 'S0/SL (in^2)'
dims can be rounded off somewhat, I just printed out part of a spreadsheet
