it's the speaker.
45's are not going to handle a 15" woofer properly.
They need 105 db and up efficiency.

Two different things. Efficiency is largely about volume. Other factors relate to control.

People who talk about high efficiency don't have full range systems. There may be a few out there with full-length bass horns stuffed into the basement or attic, but otherwise, they're deficient. People try to overcome this by adding non-efficient woofer and sub-woofer systems, but it's not the same. In fact, I'm always astounded to hear someone rant about the tiniest nuance of equipment design, then throw it all away with a split speaker system. Headphones are another matter, one of the few ways to enjoy the goodness of tubes like the 45 without moving into a 30,000 sq ft house. :)

Maybe so, maybe not so. Don't know. The JJ 2A3, OPERATING as a Type 45 ( 27 mA. biased ) sure played the system well.
Its a VOTT A7-800 with SUPERB wiring from the AC cord of the amplifier, through custom crossovers, with ( 9 AWG ) wiring to EACH 515B woofer's polarity, soldered to the voice coil's terminals. Probably among the one or two best-wired VOTT systems ever done in audio.
All I know is, an ST and Globe 45 wouldn't power my system properly in the mids on piano, etc. I am guessing my rig is maybe only 102 dB, but VERY effectively wired through out.
Mind you, folks, I hear all the good things a 45 does, that sucks people in, but if its deficient in the mids, I won't use it.
Maybe, ( I could imagine ) an EML 45, with a much larger cathode, and the filaments linear spaced, will be OK. The ST and Globes,..... were not !!
