Older Altec horn speakers

Model 15 over looked and affordable, to me better in smaller space than 19.

Johnnyb53, The L65 Jubal link shows that sensitivity is 78dB. Is that really so inefficient? Given higher impedance, it might work with tube amps, but it would certainly be a stretch for a lot of tube amps I know...

Sensitivity ratings weren't standardized in the least back then. Altec used wide band pink noise measured at 4 feet. The resulting figure is not at all comparable to what you get today with a 1KHz test tone measured at 1M. The Jubal is pretty efficient, but I still think there are better-sounding Altecs from that era.

The Model 15 is sort of a Model 19 Jr.--a home VOTT sensibility, but with 12" woofer and smaller horn in smaller cabinet. Pics and specs here.

The JBL L-65 Jubal is probably around 93 db per watt at 1 M... the 78 db figure is from 15 feet away.

listening to wrti fm on a pair of recapped 890c's now via an upgraded ee preamp, triode strapped st-70 (hovland caps, magnaquest power transformer) sourced to an lt 110 scott tuner. i've attached a hsu clone sub. if there's a sweeter-sounding set up, you'd have to enpanel a jury to prove it to me.

I once owned a pair of Altec Model 15s and eventually parted them out when I got a pair of UREI 813As (using the Altec 604). The folded 32B horn on the Model 15 were grainy sounding and the woofer was not even Altec sourced - apparently they used something from RCA.

In the past I've also heard some pretty trick VOTT systems with cement horns and triode amplifiers - though everything sounded BIG and golden with amazing dynamics, the overall sound was quite colored - every record started to sound like it was mixed and mastered at the same studio. Of course that could have been the front end, preamps or amps...
