Altec A7 yay or nay?

They are impressive but they have their place. I like them much better with the 500hz horns than with the 800 hz horns. Any that someone saw with JBL anything in them had been Frakensteined. That's OK, you just should know. They are very non linear. They are very bright. They have dynamic range like nothing currently being sold to consumers. If you use D130s they will be extremely hot in the mids. They tend to be anyway. Probably a JBL 130A or any number of Altec 15" or a lot of things being made today. They aren't accurate, but they are very impressive. If you want to play the dead like you are there. They will do it. they can use a good sub woofer, but it will need to be capable of significant output. A good 1/3 octave equalizer wouldn't hurt them any. They can be used with the horns on top or in the vent.

The K horns are very efficient. Paul Klipsh is famous for saying what the world really needs is a really good 5 watt amplifier. If you don't have the upper end, JBL or EV parts, or even Altec work well. Klipsh used EV. If you are thinking of adding cone tweeters, I don't think you will hear them.

I  had have an A7 voice of the theater for a while and yesterday the frequency on the horn was going on and off... the base of the speaker was working fine but with out frequency it sound it like crap. My question to you is, even though I had this speaker for over 4 years I am kind of new on this. Do you know by any chance what is that I need to replace in my A7 home of the theater speaker  in order to properly work again? Please if someone would be kind of guide me to this issue I will really appreciate it. Daniel.

Please be patient with me I am new and this forum....thanks for your help.

If they still exist, try contacting Great Plains Audio. They have all things vintage Altec.
