I have 2 pairs Utah V12RXC21 which come up on Ebay frequently and, according to legend, were made by Utah for Altec, or maybe the other way around.
Anyway, as measured with a P.E. DAT, the specs are
Re 3.6
Fs 27
VAS 237.9 L
QTS .31
QMS 2.50
SPL 94
WinISD graph for 2 Cu Ft sealed
I have had them in a smaller cabinet that was on hand and played around with ports and KLH type vari-vent then sealed. Boomy with a port, nucely balanced sealed. After I got the DAT thingy and had some T-S specs, I got serious. Vifa DX25GT09 will cross at 2500 Hz first order for an overall 95 dB Sensitivity. Not, strictly speaking, High Efficiency, but not bad.
