The best speaker you ever heard?

Yes Tbohner...a great speaker. Too bad no manufacturer ever decided to duplicate or continue this speaker. Not too expensive except for th Hartley woofers.

Professor Aubrey Castell, University of Michigan, mid 1970s. Fascinating guy.

The best speakers I ever heard are my custom 4-way horns :

Two 1954 Klipschorns with JBL 1504C's below 100 Hz ;

short, straight 1:1 compression ratio exponential-curve horns with 50's vintage JBL 130A's between 100 Hz and 500 Hz ;

round tractrix horns machined from laminated MDF blocks with 60's-vintage JBL 375's between 500 Hz and 10 kHz ;

and 077 ( or 2405 ) supertweeters ( 10 kHz+ ).

The filters are 3-way 4th-order active s.s.. except for the supertweeters', which are 1st order passive - just single Hovland caps.

The amps all use 2A3 triodes : custom ( UTC LS-58's on Webster Electric Hammond organ amps ) ppp x 4 on the Klipschorns ; Brook 12A's on the upper bass, and an A.E.S ( Cary ) SE1 on the mids + tweets.
