muel Posted July 16, 2018 Share Posted July 16, 2018 Interesting! This would be good for a build I've been considering for a friend. Quote Link to comment Share on other sites More sharing options...

Guest wdecho Posted July 16, 2018 Share Posted July 16, 2018 I have used the exact same combination with my LaScala bass bin. More efficient than the stock K-horn, LaScala so it would need some attenuation for use with your woofer. Larger soundstage is biggest difference I noticed. when it comes to horns bigger is most of the time better. Excellent deal for someone that likes to play considering you are getting horns that sell for $200 or more on ebay and the excellent Klipsch drivers.

kg4guy Posted July 18, 2018 Author Share Posted July 18, 2018 Yes $200 is for average looking ones these have no chips in the paint cracks and they have the Altec logo's still on them I will ship. Quote Link to comment Share on other sites More sharing options...

Want to build a 2-way with horns Cheers, Emile Quote Link to comment Share on other sites More sharing options...

Guest wdecho Posted July 18, 2018 Share Posted July 18, 2018 The 511B horn was used extensively as a 2 way in the Voice of the theater speakers. Of course you will need a driver that can produce from 500hz up in a 1" driver which is not that easy or cheap to find. Quote Link to comment Share on other sites More sharing options...
kg4guy Posted July 18, 2018 Author Share Posted July 18, 2018 LOL there is a lot of Altec 1" drivers for sale that do exactly that so I'm not sure what you are talking about. I have purchased near mint used Altec 909 drivers for less than a new pair of K55's. Quote Link to comment Share on other sites More sharing options...

I know what he's talking about. It may be true that Altec has a 1" mid-driver that dips into the 500 Hz range, and maybe they are all over the place easily found. I'm not an Altec person so I wouldn't know. But all the other CD's I've seen that can drive 500-20,000 Hz are NOT cheap. The K-63-N CD in my CF-4's can drive 400-20,000 Hz but the last replacement price (new) I saw was around $800 each. Quote Link to comment Share on other sites More sharing options...
