Do you Think Altec model 19 is outdated speakers ?

@mdalton .Altec Model 19 s super tweeters apparently prototype of  one the 7 ever made  but never manufactured whatever the reason !  similar to 604 G Tweeter section İt has got a toggle switch 96 to 98 db sensitivity . My chief engineer back in 1974 A. İngles acquired from KDKA radio station from Pittsburgh  case made by myself painted in white to matched Model 19 speakers at back of Tweeter marked ALQ 005. also Altec model 19 manufactured in white finish 16 pairs I've been told .

Crites or something like that makes new crossovers.might check into that if you feel you need to update. I did on my voice of theater and it helped.enjoy the hunt

@mark200mph ,original N1201-8A crossover has been updated also another crossover with paper in oil caps,c-cores for bass coils and auto transformers inside the horn unit I  can use both flicking over by toggle switch.

WOTT Are remarkable speakers enjoy it.

I'm a big fan of Valencia's and own a set of heavily modified ones. They do about everything right but know going in, they need added bracing, better sound insulation, upgraded internal wiring and obviously upgraded contemporary aesthetics. They can use some added weight to deaden the cabinets too. With the right electronics though, they are truly sublime and for my listening habits are pretty terrific. Yeah, surely not for everyone but when done right, Altec Valencia are pretty special. Just my opinion

 I do not understand your defensive response.  Seems like you're looking for affirmation again.  I said that I was glad the Altecs are musically compelling to you.  That is all that matters.  I was avoiding a direct response.  But I will now provide it.  While the original model was technologically advanced for its day, I have to agree with the description of the pros and cons delineated by @br3098.  While acknowledging your model is updated, state technology has advanced beyond.  
 

Horn loaded speakers with dynamic drivers and tube electronics are an acquired taste that many prefer.  That’s ok.  While I acknowledge and hear the many benefits of horns and tubes, I prefer the overall performance of dynamic driver speakers and solid state electronics.  To each our own.
