FWIW: Altec 288-8G - Electro Voice HR60 HELP

So if I understand correctly, the EV horns have a slightly smaller throat? Is it just the HR60, or the HR90 and HR120 also?Quote:

According to some quick research those horns have a 1.3" throat. Any way to make them larger to match the 1.4" Altec drivers?
Don, it's just fiberglass. A dremel tool would make quick work of it with a sanding drum.
I recently had a set of HR90's, they were huge. I never unloaded them from my car, sold them that quick. To big for me at 40" across.

Well there's this method...;)Quote:

Dunno, just found the thread in a quick search and posted it.
Make a 2x longer tapered reducer than the driver's internal one to minimize reflections back to the internal throat or align bore the horns after adding an epoxy layer [or four] of fiberglass matte around the exterior assuming the flange is large enough to safely mount/support a 2xx.
Otherwise, there will be a lot of reflections from the mouth back to the horn's throat and a separate set of much higher frequency reflections between the horn throat and the driver's internal one, but never having done any experimenting can only say that folks with keen hearing should theoretically have no trouble hearing a difference if one could make a suitable comparison, though the reality is that the worst case scenario probably will be just a lower extreme HF output; i.e. what happened when I mounted an 802 to an 805 multi-cell with just a gasket.

+1 :D, beat me to it, this is what I meant by 'align bore', then saw your link as I going to go search for one to link.Quote:

I've never used them, and just for the record they're painted black. :D
Sounds like near enough to 1.4" that just an Altec gasket is required, though a perfect bore match will help the extreme HF a bit if no super tweeter is used.

I think that I paid $60 for one of my MRII564's and $120 for the other one with the 1 to 1.4 adapter and a Altec 909. I cant remember what I gave for the MR5120. Check out Phil's E.V.'s. If you like them make offer. When E.V. first came out with those we nicknamed them urinal horns.
I have heard that some of the big EVs are great, but I have no experience with them. My recommendation for cheap thrills is the Altec 203B, the two cell giant with the huge sound and the narrow pattern. For living room use they define the possible for a domesticated multicellular. Big goose bump vocals!
Little late in this but I would look for a set of LeCleach horns in the DIY forums or eBay. I sold a set with JBL 2435HPLs a few years ago. I have 1005bs, 511bs and lecleach horns with " and 2"'throats. I have also owned Klipsch and have heard the 402, tract Rick and various tad clones the lecleach horns are very hard to beat in imaging and smoothness with very little horn artefacts.Quote:
