Does anyone know of a currently-sold woofer with 0.3 > Qes > 0.2 and Qms about 30 times Qes? I need this type of woofer to test a bass extending network.
I've had some success with Pioneer DVC 8" B20FU20-52D with Qes =0.23 and Qms= 4.05. My calculations show that a higher Qms/ Qes ratio will improve the amount of extension possible.
The size of the woofer at this point isn't of concern to me, but I would like to limit the unit cost to maybe $60. or less because I'm not absolutely certain that I can achieve success with it.
A woofer that fits the bill that I can't locate is Pioneer 6-1/2" woofer C16LU20-51F. This woofer has Qes = 0.23 and Qms = 7.63, so Qms/ Qes = 33.
I don't think that it would be easy to modify a woofer to obtain a higher Qms.
Any help is appreciated,
Pete
