Yes, too low efficiency, even worse than Altec 515, (when loaded with small throat, in proper FLH, NOT A7 type "horn" which disqualified it also for my usage... 
I don't know how "colored" Tannoy would sound with properly designed horn though... 
Seperate amps could take care of lack of efficiency compared to the rest of the system after everything else was dialed in. 
I would still like to try 15" Tannoy Red or Silver (Gold is lower quality?) in 65Hz horn, (and am building horn with capabilitys for this trial) running from ~ 80Hz to ~400Hz, but will need to be AFTER five-way horns are built, and DSET amps are built, and working (as the Tannoys are less efficient). 
Might be able to build "resonating oops" and mid-bass in same channel. 

I don't know if this is what Dresden is thinking in this thread of not; I'm still not clear on his design / goal. 

Perhaps it's something like this: http://cgi.ebay.com/Pr-Tannoy-15-Monitor-Red-Autograph-Speakers-Huge-Sound_W0QQitemZ190266415283QQcmdZViewItemQQptZUK_AudioVideoElectronics_HomeAudioHiFi_HiFiSpeakers?hash=item190266415283&_trksid=p3286.m63.l1177
