Looks like a set of 200's and maybe 100's?

Are there speakers in that photo? Oh, yeah! The little ones or the big ones?
You do know about www.humanspeakers.com, yes?

Ha ha. Both! I did not know about the link. I'll go do my homework now. But I suspect the EPI experts would rather show their stuff and be the first to announce what these are ... and were those experts inclined to follow that with, "Go get them now" or "All time classic speaks" or "Piece of crap," that would be quite impressive ......

If they're EPI's, they're not likely crap, unless they are from very late, when it was just a name owned by... Harman International, or whomever.

Uh, could you reduce the size of the image a little?robobxman said:

Ok, ok. I didn't take the pic. I snagged it from a craigslist ad to save people linking to a small crap photo versus having the thrill of opening it directly. Having looked at the human speakers site, the smaller speakers (really really small in the pic) look like they are from the A series. Maybe a 100 or a120. The large ones (still really really small, but larger than the other diminutive ones) appear to be Epicure 15s based on the wider strip of wood on the bottom of the grill. I'll confirm tonight when I talk the owner.
Syds - congrats on your 400th post. Glad I could be a part of it ....

woah, the specs on the 15 are very good -a 45+ lb speaker with the Burhoe "module" (8" and airspring tweeter), in a really big cabinet AND a 12" passive radiator. Lots of vintage style on those to boot. Better 'Buy it now' fast, that is a very interesting combination. (Recall liking a panasonic speaker with a passive radiator a long time ago, it could be somewhere between a acoustic suspension and ported bass effect, 12" is a lot of area....). Thanks! -sf

sf - I thought I knew speaker basics until now. Here's what I understand:
really big cabinet = large wooden box
ported = hole in the front of the box
bass = boom boom
acoustic suspension = what my old ARs are
Here's what I don't:
Burhoe module (like a flux capacitor?)
Airspring tweeter (like air shocks?)
passive radiator (like the one in my wife's jeep that leaks?)
And what's sad is I'll probably buy these now because, without understanding half the things you wrote, I'm excited about the find and how they will sound. I think I need help.

OK, we'll take it slow
THis is a Burhoe (the module in the middle):

... and this photo illustrates a Burhoe Module, which is an 8" extended range woofa and an "airspring" (concave) dome tweeter.
Those large things on either side of the Burhoe in figure 1 are EPI 1000's, which are chock full of Burhoe modules.

Now... about passive radiators. They're just an expensive variety of a port (believe it or not) -- or a cheap variety of a woofer. Depends on your perspective.

Robo,
Yes buy now. !!! Quick! It is nearly certain that those speakers (Epicure 15) will be in the same league as the best sounding "conventional" speakers money can buy. The little one's I'd say you won't really need, if they are indeed late 80s A10s, try to leave those behind if possible.

Yah man. I was also amazed to see that woofer "extend" (horizontally) recently when I watched what happens as my HK930 powers on and off. The distance it can travel when pushed slowly by voltage is .... well.............shocking.mhardy6647 said:

I am anticipating my 1st experience with EPI and passive radiators. I just bought a refoam kit for a set of EPI A500s. These have a 10" active in front, and a 10" passive in each side. They look similar to your EPIs, except less wide, but with the pedestal bases.
I picked my set up at a local thrift store for $12 for the set, but the woofer surrounds are totally missing, from rot. I can hardly wait to hear what they sound like after refoaming...

Robobxman:
I do hope you took my posts to be a feeble attempt at humor, trying to play off the tone of you own posts. Keep up the good work, I like it!
I actually was in a bit of a hurry when I posted earlier... my wife and I were off to Great Meadows NWR in Concord (MA) to look for migrating nighthawks (we were skunked... maybe next week). Now I can add a little explanation.
So... Winslow (Win) Burhoe was the Man at EPI (Epicure Products Inc.) originally in Newburyport, MA. His early designs were based on a "Module" of a 6-1/2" (or 8") woofer and the concave tweeter. The woofer was a high-compliance model and also had extended HF response, so the XO to the tweeter was fairly high and very simple (just a capacitor). The woofer ran 'free' (no inductor to roll it off). Some of the larger EPI's (like the incredible 1000's in the photo) had multiple "modules". No less than Terry Cain (Cain & Cain audio) listened to a pair of 1000's and pronounced them among the best converntional speakers he's ever heard.
Passive radiators were all the rage in the late-1970's. Well-implemented, they extended LF performance (like a port) with reasonable sensitivity, but allowed one to use a smaller woofer with good transient response and/or extended HF response. The idea was, of course, to keep the XO away from the midrange, so that both response and phase were not mucked up in the frequency range where our hearing is most acute (and attuned).
EPI made some great speakers for the money... their better speakers generally bore the "Epicure" name. You will like them (well, I expect that you will).
Please DO report back to the class when you get 'em/get 'em going.

A final note on Win Burhoe
Ol' Winslow is still around. Here he is seen illegally practicing medicine on a loudspeaker system.
Interestingly, he still has a speaker company, although as best I can figure it, they're not actually/actively producing speakers at the moment.

Too bad, 'cause they look like they would be a tremendous value for the money. Note that there's a forum there, too... in which Mr. (Dr?) Burhoe participates regularly.
