No doubt one of these -- priceless: retro vintage modern hi-fi: Western Electric Mother Of All Coax
A long time ago, about ten years, I was in a small recording studio that had a speaker that looked like my 604's but was much bigger, it sounded fairly harsh as I recall and was used as a near field monitor in large cabinets, as I remember they were about 5.5L X 3.5W X 2.75D and hanging from the ceiling directly in front of a mastering board that had hundreds of knobs and switches. This small studio on lake ontario did record some well known acts as I recall, one that I remembered was a band called "Bush" that had some success. So my question is did Altec or another company make an 18 inch coax that looked very similar to 604's?

That's wild! The only 18" coax I knew about was the P.Audio 18. A really great driver if used right. An 18" woofer cone makes a great horn.

Wasn't the BTH a Westrex? or has my brain turned completely to mush?
Your neighbors called. They like your music.

> That arrangement would nicely circumvent Roosevelt's Anti-trust legislation of 1949 ( which somewhat forced W.E. to pursue growth outside of the U.S. , effectively making it go "global" ) .

Thomson-Houston
Metropolitan-Vickers
British Thomson-Houston ( BTH )
Associated Electrical Industries
(British) GEC "General Electric Company"

Except that it moves.
Here's a pic of that WE coax complete with the horn from the Silbatone collection....multicell on the HF and a re-enterant horn for the bass.
