Default Misco in a T-TQWT or TH

Hi All

I have been reading a lot about T-TQWT & tapped horns of late as I am trying to build the bass support for my unity horns. I really like the design ideas that focus on music quality as well as achieving 20Hz to 100Hz with reasonable SPL (>110dB). So I have tried using Hornresp with a MISCO OC8W-4B but not getting far.

POWER MAXIMUM (WATTS) 300
POWER RATED (WATTS) 150
MOUNTING DIAMETER INCHES 7.8
TOTAL DEPTH INCHES 4.3
RATED IMPEDANCE (OHMS) 4
RESONANT FREQUENCY (Fo Hz) 18
FREQUENCY RANGE (Hz) 15 - 3,000
SENSITIVITY 1 Watt/Meter (dB) 87
REFERENCE EFFICIENCY % .27
TOTAL Q (Qts) .15
MECHANICAL Q Qms 3.9
ELECTROMAGNETIC Q Qe .16
D.C. RESISTANCE (Re OHMS) 3.8
COMPLIANCE EQUIVALENT VOLUME Vas (Liters) 94.6
MECHANICAL COMPLIANCE OF SUSPENSION Cms mm/N 1388
BL PRODUCT BL T*M 12.7
DIAPHRAGM MASS MMD grams 63
DIAPHRAGM MASS INCLUDING AIRLOAD Mms grams 65
VOICE COIL OVERHANG Xmax mm 9.0

Not sure of the Le so I have asked Misco. I have been using 2.0. It's an 8" (205mm) driver and is designed with car audio in mind so good for small volumes. That's what attracted me to it initially. I am thinking one or two together for each side.

thanks in advance
