In the mid 70's I was stationed in San Diego CA and had previously purchased the RTR 400's while in Bremerton WA. I also purchased the ESR-6 Tweeter Box to sit atop them. At some point they developed a problem and since Canoga Park was a reasonably short drive I took them there for warranty repair. These folks were most helpful. While I was waiting a very nice fellow named Joe Alinsky took me for a tour. During that time there he sold me a pair of blem 400's to take home. At that point I began to build the system I currently have. It consists of the ESR-6 box, 8 D150 mid range panels in their own cabinet and I had a cabinet shop in San Diego construct me two woofer cabinets out of 1 1/4 MDF dense particle board each one at roughly 8 cu/ft. The woofer cabinets are internally separated as was advised by the folks at RTR. The problem was this setup proved too much for any one amp - at least one I could afford at the time - to drive this system. Yes, the AR D-150 did a fine job but was out of my reach. The solution was to use the AR EC-2 crossed at 400 Hz a Phase Linear 400 for the lower end and a Crown D-150 for the upper. The Crown was eventually replaced with a Threshold 400a. As each person has different taste - and hearing - aside from the Infinity Server Static 1A's I've never thought to part with what I have. Now that I'm OLD and realizing that when I go my son will put all this in the dumpster, I've thought to sell it off. Sadly, eBay seems a poor platform to use as there is no shipping possibilities - each woofer cabinet is over 200 lbs. Any suggestions - or offers- would be greatly appreciated! If you've read this far I thank you!
An old thread with lots of great informed info., to which I can add only:
Other loudspeakers that incorporated the RTR ESL tweeter were the ESS Transtatic I (the first ESL driver I heard. I now own a pair of TS I’s) and the Fulton Model J (the ESR-6 cube, placed atop the Fulton Model 80 for the midrange, which sat upon a transmission-line loaded woofer enclosure). The Transtatic also used the famous KEF B139 oval woofer (in a 1/4-wave transmission-line enclosure), used in pairs by David Wilson in his original WAMM.
