Bozak model info help

Anyone familiar with these Bozaks? They are 44.5 tall, 26.5 wide and 16 deep. I think the 207b woofer had a tweeter or two attached, and there are also 4 tweeters in array on right. The mid is inside the salad bowl on bottom.
Thanks in advance, Bozak experts!

Looks like a B4000 / Symphony minus 4 tweeters. Are the woofers 16 ohm? I cannot make out the number in the photo. If they are 8 ohm it is not a true B4000. The B4000 is the only Bozak model that has 16 ohm woofers. The cabinet size is right and that is the original Bozak cabinet damping material.
Give them at least 20-30 watts, tilt them back .5-1.0 inch in front, tweeters to the inside if you got a mirrored set. The reason to tilt is the treble is intentionally very directive to keep the sound off the walls of the room.
Now sit back and enjoy true audio bliss.
 
I think Jimerson is right, each 207b should have a couple of tweeters mounted to it, for a total of eight per speaker.
 
It looks like 8 ohm to me in photo, model B-207-B. I could not find this configuration in any Bozak literature. The dimensions are right for the Symphony, but only 4 tweeters. These are available, but I have not seen them in person yet.
Thanks for the info.
 
I thought all B-207's had built in tweeters, but I sure aint no Bozak expert! The symphonies I saw online had 8 tweeters in a vertical row. I'm gonna go see these in person, if you guys think they're worth the trip, soundwise that is.
 
I am not real technical, but can four 8 ohm tweeters even the system out to a total of 8 ohms by using 8 ohm woofers instead of 16 ohm woofers with 8 tweeters? The mid and tweeters are all 8 ohm.
If those are 8 ohm woofers someone monkeyed around with the original cabinets.
 
I think what we're looking at may well be a kit-built Symphony (Modern cabinet). And since Bozak drivers were at this time available in both 8 and 16ohm versions, I'm assuming the guy who built the things must've prefered 8ohm. I still think with two tweeters per B-207 we end up with eight tweeters per speaker. How exactly does this work? I have no idea.

As to how they might sound, I would expect them to be pretty nice, but I have no direct experience with Symphonies, only Symphony. That is to say, I only had one. In the limited screwing around with it I did I thought it sounded good-- good enough to hang on to it for six or seven years, just in case another single turned up, which never happened. Eventually commonsense prevailed and the thing went back to the Goodwill whence it came. (I'm just now able to stand up straight again, i.e., I carted the damn thing back by myself and it's, um, you know, heavy.)

Good luck, whatever you decide.
 
Yeah, I'm liking the kit idea. That also explains why most of the Symphonies I saw online had the midrange in the salad bowl on top of the woofers instead of the bottom like these. Found some 68 Bozak catalog literature, pretty cool. They say the Symphony has 4 tweeters, but on the next page they show each tweeter as a pair.

Hey Jimerson, the Symphony in the Bozak stuff you posted, that's the one (1) I had. Is it just me or is the Modern a much better looking cabinet?
 
Yeah, way better. I like older speakers, but I'm not crazy about the cab designs back then, although most were well made.
 
My Symphonies had 8 tweeters each side, too, but in a vertical line. Smelled like a pair of wet dogs -- but sounded nice if a little dull on top -- good for classical music.
 
Looking carefully at the photo, it looks like the cab iscut for the 8-tweeter array. The cab is a Symphony from the specs. A nuber of persons seem to feel that the speaker sound better with 2 or 4 tweeters rather than the 8.

As for sound, I ain't giving my pair up any time soon. Not many systems sound as good with classical and jazz.
