Zenith console open baffle test mules

[Poultrygeist]

These old Zenith full range drivers ( silver ones in the middle ) pulled from a phono console sound pretty good in bi-amped OB. I'm pairing them with a PE close out super horn tweeter with a single 1 uf cap for a decent blend. The bass Alphas have their own low pass filter. I used the original Zenith console baffle cut in half. The old open back console speakers were designed to work in open baffles so it's not surprising that they do.

I am planning a similar project.I have a 15 and a small 10 from a console.The 10 has a beautiful midrange...electric guitars sound very real.
Still looking at tweetage.

Where are you crossing to the sub and tweeter?

I.R.,

I believe I have 80hz filters on the woofers. The Zeniths run full range with a cap on the tweeters. When I get the Behringer out of my main system I'll be able to dial in the points.

These Zeniths from the 1950's are 10 inch and I think they have alnico magnets. The cones are unusual in that they don't have accordion surrounds. The cone material goes all the way to the frame edge.

It's lots of fun experimenting with cardboard wings of different sizes and fooling around with such nice old drivers.

The 6v6 mono tube amp from the Zenith console is in great shape but I'm not sure what I'll ever do with it.

Look forward to seeing pictures of your project.

I think mine are the same way...no accordion surrounds.

I will probably go passive 3 way crossover first with sub and maybe later try multiamping them if I like them enough.

I still have the horns too but I dont think they are hifi enough to use for this.(I like ribbons )
How high do you think the Zenith is running with no inductor?

Fairly high as they sound ok without a tweeter.
