How loud Posted August 23, 2023 Share Posted August 23, 2023 I have looked all over the web and sites to find info on these Beta Sound model 1001B. From what I can see it used most of the drivers that were used by Klipsch. The speakers I found did not have the original woofers anymore. Midrange driver appears to be a Atlas K55V with push terminals no badge on them or the tweeters that appear to be K77’s. The only thing with a label is the EV - STR tweeter protective device. The horn looks just like the Klipsch K700. From what I have been able to find out is the woofers were special made K22’s. Can anyone help with some info on these and specs. Thank you Quote Link to comment Share on other sites More sharing options...

billybob Posted September 17, 2023 Share Posted September 17, 2023 Look a little like an Altec design. Know someone here who may give it a stab. Welcome! Quote Link to comment Share on other sites More sharing options...
OO1 Posted September 17, 2023 Share Posted September 17, 2023 Beta Sound was an outfit from Texas , no relation with klipsch or Altec VOTT , EV T35 tweeters were used by EV-Speakerlab among a few , while klipsch used to be the biggest client of EV , btw the Pyle woofer is not original , the Beta Sound model 1001B woofer was supplied by Eminence .

Bacek Posted September 17, 2023 Share Posted September 17, 2023 Tweeters are Electro Voice T35. Klipsch was using them as K-77 but he was not only one. That version (chrome front) was also available to buy as normal (not only for OEM vendors) component from EV. Quote Link to comment Share on other sites More sharing options...
How loud Posted September 18, 2023 Author Share Posted September 18, 2023 The midrange drivers appear to have been used by Klipsch. The horn was patented by one of the owners of beta from what I read. The mid driver looks like the atlas K55V. Do you know the model number of the woofer used or the Thiele Small parameters Quote Link to comment Share on other sites More sharing options...
How loud Posted September 18, 2023 Author Share Posted September 18, 2023 Thank you for your answers and still searching for info. Trying to figure out a replacement 15” woofer for this cabinet. I may just use a JBL 2226. Quote Link to comment Share on other sites More sharing options...
