3184's on eBray

[Altec Best]

GPA builds brand new ones, certainly they can recone older ones.

+1 Yes Bill Makes the 3184 and has the correct cones for them.So you can still buy brand new GPA 3184's

I have them in the factory cabs. Simple bass reflex. The system is called the 8184.
I use them with my model 19's crossed at 70hz. The 19's run full range.
I paid a whopping $350 for them off Ebay, delivered!

That's a sweet deal Ron !

Even though it's rated as having a response up to 2000 hz---being an 18" woofer, I'd use a 500 hz crossover and possibly an 802-8G h.f. driver with a Mantaray horn (or 511B).

Two things, one is it's down more than it looks at 2K. It will be beaming like crazy. So on axis may be OK, but off axis will be awful. At the risk of oversimplifying, think of the cone diameter ratio to the wavelength being reproduced. The bigger the cone, the shorter wavelength it will beam at. So 12's should cross lower than 8's, 15's lower than 12's, 18's lower than 15's, and God forbid anybody wants to use an EV 30W.

It's no accident tweeters are smaller than woofers.

You might get away with 800, 500 would be better.

Personally, I would do a nice 2 way from 100 up. If I could count on being able to finish it, there's a pair of Bolero's in Columbus CL.

Altec Lansing Bolero's 890c




Those cast frame 10's are worth the 80 asking. I have a single 416 that might make a decent sub for them in a low tuned box and just run the Boleros 100 up.

Makes sense, that's why I was recommending a 500 hz crossover (or even a 300 hz crossover point if using a large format h.f. driver). I figured that above 500 hz you'd get much better sound out of a good h.f. compression driver/horn combo--the beaming explanation gives me a better understanding as to why. Do you think a 288 would do a better job with these (for a two way system) than an 802-8G crossed at 500 hz (for home hi-fi)?

BTW, how are those horns on the Boleros? Decent upper h.f. extension?

I rate them NBAT- not bad at all. Hook them to 200/ch and crank ACDC if you want to release the magic smoke though. They are Heppner. Hepp Horns were a big DIY staple right after this time. Cerwin Vega basically scavenged Heppner and shut it down.

I wonder if GPA can build up 3182's?

Those would be my preference in 24 ft3 cabinets tuned for 20hz.

IMHO, the 288 is a better sounding driver. Especially at 500. The 802 has a bit more highs, but I think the 288 sounds better across the range it does. YMMV.

At 500 the ones with the pot casting...288G (old phase plug) and 288H (tangerine) have the advantage due to extra mass.
Tip- Often you can buy 291B (old phase plug) or 291C (tangerine), off the Symbiotik frams, and replace with new GPA cheaper than you can buy G or H model 288.
