Audio guys - can you identify these speakers?

[LeeH]

Don't know what they are... don't recognize the "A" in a circle logo. Got them at a garage sale this morning for $4... cosmetically, they're ok, but they sound great. Figure they're either something high end I've never heard of or they came out of a white van.

But, seriously I think they sound way too nice to be white van speakers. I should have asked the seller, but they came from a "multi-family" garage sale and I'm not sure the woman who told me $4 had a clue. I think she gave me a big discount because one of the grills was loose... as in, someone had pulled it off to look at the drivers.

I would guess Angstrom. A Canadian company. Not high-end but certainly decent. Never a big commercial brand. Started by some guys that worked at a Toronto retailer called Ring Audio back in the early 80s. The guy on their website has been a distributor in Canada for decades.

My speakers do look similar to one of their current models... just odd that I can't find anything with the "A" logo. Doesn't A in a circle mean "Amps" in electronics short-hand?

Maybe Audio Intelligence. They mostly do commercial stuff. Those look great for 4 bucks - heck, you can even Bi-amp em. Good score if they sound good. They would be perfecto in the garage!

Those tweeters looks very similar to the Titanium driver tweeters that came in a lot of 90's JBL LX-series stuff. Probably sourced from the same company, as those obviously aren't JBL. They are nice however.

Very interesting. It's a D' Appolito configured, bi-wired speaker with additional angled ''rear- firing tweeters''.

A steal for $4.

D' Appolito

wow!

you stumbled onto something there - might be a wiki on him. His 1st name is Joe. He is a legendary speaker designer.

[imcarthur]

Joseph. And it's not true D'Appolito which requires the tweeter to be in an exact line with the woofers. The driver in the rear further blows it. The designer was trying to add some ambience - quasi bipolar possibly.

The way I understand the D'Appolito theory, there is an intersection of the output of tweeter & woofers at a specific point/distance for best phase accuracy.

Well, Wiki says it's: "allowing the drivers to have similar horizontal dispersion, resulting in absence of any sudden change in directivity with frequency"

I was (he says sheepishly) repeating Focal's Focus Time spiel.

True. Quasi D' Appolito would have been more accurate.

Yep and I'm sure the rear firing tweeters gave it a more ''planar type ambiance'' or (muddled the soundstage?)

I have a vague memory of these speakers from the mid to later 80's.

Funny, I noticed that too! I had two matched sets (2- 10" woofers in each tower front, 1- 8" bookshelf rear) for surround sound that I bought in 1993, back when Dolby Surround was pretty new and not yet Dolby Digital.

I loved those JBL's and sold them in 2004 for $20 a pair at a garage sale.

think he was at Snell for a while

'time-aligned' I guess...
