Class D amplifiers have very little phase shift

...ran into a pair of these @ a 'vintage' MCM/modern furnishings store here....

"For sale?"  No....only audiophiles seem to like them....
"*L* You're talking to one....but I don't blame you.  The white ones' are on the rare side.  Just curious, and I didn't think you'd want to part with them."

Not to everyones' taste, but a 'pleasant sounding' JBL.   Kind of an era omni in its' way.  These were an 8~8.5/10, the white finish needed a touch-up cleaning and wax..

Nice to see an appreciated 'oldie'...*S*

Now that gives me ideas!! :) 

?!.....*pause with bated breath*S*

Oh, sorry, nothing that spectacular.  I was thinking of using a slot to turn directional drivers into omnis.
While the concept is cool, I'm not convinced that in the living rooms I can afford omnis are going to be all that for me no matter what.

*G*  Well, the JBLs' are 'pleasant'...'Perfect'? 

Mmmm....no.  If one desires an unobtrusive speaker pair that would have a potentially high WAF in a 'modern' or MCM living space...

They'd work.  Will they rival SOTA?

They're over 50 years old....one would have to accept that. *S*

I'd seen and listened to them 'back then'; couldn't afford them at the time.

I've 'moved on'.....(Read your mail...)
