Re 5.1 Ohm
Qes 0.26
Qms 6.9
Qts 0.25
Vas 87.3 dm^3 (3.08 ft^3)
Sd 529 cm^2 (82.00 in^2)
Xmax 7.50 mm
Xdamage 21.55 mm
Mms 56.0 g
Bl 17.5 N/A
Le 0.83 mH
Mmd 42.2 g
Cms 0.22 mm/N
Rms 2.3 kg/s
Eta Zero 2.93 %
EBP 173

Does anyone know how to graph the response on this combination? Thanks in advance

They are in spec.....but why???? Those are stupid expensive. The Eminence drivers are way cheaper. Don't know where you are from. Is Eminence available where you are?

6 - T39 3012LF
4 - OT12 2512
1 - T24
1 - SLA Pro
2 - XF210

Welcome to the forum.

Yes, the driver is within spec for a T30, T45, and T48. Might be okay in a T39 too. Just barely out of QTS spec.

Disclaimer, the chart below was derived by reverse engineering the dimensions in the plans and entering them into the horn modeling software, HornResp. I believe they are close enough for the sake of driver comparison. Although, I wouldn't count on them being ultra accurate.

Thanks very much. Which part of the enclosure did you consider the throat? and how many segments did you use? I have hornresp but have never reverse engineered a design. Thanks again!
