Im interested on Alpairs driver, i built JX92S GM's ML-TL which works nicely, real bass and overall balanced.
but now i'm interested to try Alpair 10 bass and Alpair 5 combination in TL box, which should look nicely and erase the necessity for the stand if its ported.
i'm sure it will perform very good.
GM or any one can help
here's the spec
Imp-nominal 6Ohm
Revc 5.4Ohm
Fo 35.0Hz
Sd 8.99mM/N
Vas 21.0Ltr
Cms 1.84mM/N
Mmd 10.73mKg
Mms 11.22g
BL 6.25T.M
Qms 2.37
Qes 0.35
Qts 0.30
Levc 288.727uH
No 0.25%
SPLo 86.2d
Xmax(1way) 9mm
Power 35watts cont.70watts max

Greets!
0.31 ft^3/45.6 Hz T/S max flat:
L= 22.9"
CSA = 23.41"^2
zdriver = 8.6"
zport = 2" x 7" long near/at bottom
Vb = Vas, Fb = Fs MLTL (long):
L = 47.43"
CSA = 23.41"^2
zdriver = 14.85"
zport = 2" x 6" long near/at bottom
All dims i.d. and approximate. BSC will likely be required if not up against a boundary or two, so combined with a low Pe, strictly a near-field app/small room driver unless used in pairs with 2x power.

You're welcome!
Low efficiency and power rating = low dynamic headroom unless the music is highly compressed, such as R&R. If BSC is used, then another 3-6 dB of efficiency/dynamic headroom is lost.
A longer line would just shorten the vent due to higher damping, so if you want to try a longer one, then a 56" i.d. with the driver down 16.81" and a 2" x 4" long vent is the max length without putting the driver too far off axis WRT typical seated ear height.
