Mod thoughts, regarding stock ALTEC Model 19 crossovers.

Wow, I guess you don't trust the Altec engineers at all if you need to do that whole list of stuff to them just for a listen.
Almost any top ten speaker list has Model 19's on the list, for a damn good reason. Altec went all out to design these for high fidelity, not sound reinforcement.
To have them and not do everything that you can to give them a fair trial is nuts. If they sound good with old caps and nothing done to them, well you can take it from there. At least give them a fair try.

Bill,

I object to "nuts" ...was unnecessary, and a poor choice of a word on your part IMHO.

READ the post I did before yours. I have no amps, and no attenuator. HOW can I critically evaluate speakers, without amps of reference quality???

The M19s are not my priority, going to ( making ) monaural 2A3 DC amps, amps with ZERO negative feedback for listening seriously, is the priority !!

Each of those new monaural amps will use three of those 1,500 Ampere ( peak instantaneous ) capacitors, in key spots. First time...its ever being done in audio !! ' Way cool.

Speaker-wise, can a properly designed bass reflex woofer, (with a horn loaded driver above it), out-perform a partial horn loaded woofer, (with a horn loaded driver above it) ?? It can't, IMHO. ( M19s vs A7-800s).

Have fun, I sure am!!
