Whoo hoo!

I will defiantly listen to them, AHH OK, sorry my bad with the JBL UHF tweet, I looked at
all the other drivers to make sure what I had an just took a stab at the tweets, there. :(
(I'll double check tomorrow an see what it is exactly that's in there)

Thanks for the heads up and the kudo's, they are defiantly slots not cats.. ;)

EDIT: They are 2405H slot tweeters.. (same as 077 I believe)

I can't remember the 07X numbers very well myself, so I may have it wrong up above there...

Slots sound better than the Cat's Eyes anyway, and usually cost a lot less to boot.
 
Got a chance to listen to them today, all controls checked/adjusted, pulled the 2405's
checked the diaphragms, measured the dc resistance of all drivers, they all check fine.
(all 4 wax seals are intact on both LE85's as well, and I don't hear anything funky)
(I want to run the woofer tester on all drivers an do an impedance sweep on them)

I actually like the sound of the speakers quite a bit, supposedly the H91 horn is not an
very good horn but the "not so critical listening an placement" I had to deal with didn't
show us any glaring objections, bass was better then I was anticipating, midrange was
quite nice an the top had good sparkle, a fairly coherent system is what I heard there.

If I can improve on this with a different horn an maybe an UHF driver I think I'd be good. :)
(from that listen I see major potential here, little extra cab work I think we got something)

Couple more pic's..

So that is a passive down in there, dang StephenJ's got some eyes...

Kegger, did you try bi-amping those ? Seems the x-over lends itself nicely to that.

Also aren't those tweeters supposed to have glass wedges in them ? I do not see them in the photo, kind of wondering how they are held in.

The Pro 2405 slots have black plastic wedges, (it's visible in the pic). The clear plexi wedges are in the 077 Consumer slots. Sound is the same if the diaphragms are correct, which they _appear_ to be.*

I've never needed a UHF driver when using my 2405's, they go high enough for me. Do they seem dull?

*I have seen some that had the wrong diaphragm installed that were really quiet until I loosened the center bolt. Seems that the Bullet (075-2402) diaphragms have a thinner spacer ring in the center and the wedge actually contacts the moving area of the aluminum diaphragm, cutting the output way down. I found that a layer or two of electrical tape added to the center ring brought the level back up... The cure of course was the right diaphragm, should be a D16R2405, not the D8R075. BTW, both the 8 ohm and 16 ohm labeled ring radiators are the same at around 10 ohms actual impedance.

(Thanks 4343 for the phase plug breakdown, an they say 2405 on the diaphragm)
Oh no there's plenty of sparkle there, thought was if I go to a different horn for the
LE85, redo/different xover's do I go for extension from the LE85 or go back to a UHF
driver and then which choice will I use for that. :scratch2:

Phase plugs are held in by a screw from the back side in the center under the foil cal.

Perch with these xovers there really isn't a good way to biamp them, the LE85 an Slot
tweeter take there xover input from the high pass section of the other xover network.

I used a Big Ole MCS 3125 (outdoor/carport test amp) to drive them, plenty O power. :)
(when they come in the house they'll get some Kegger tube gear)..:smoke:

Took an hour to get the test amp going, the protection relay doesn't like to come on, I
will have to open the receiver and see about fixing the relay here down the road now. :(
(DC-offset is fine so I believe it's the relay itself at fault)
 
Nice score, guys. 076 are my favorites of the ring radiator JBLs, but the 077s are no slouches. Looks to be a great starting point for a nice set of speakers.
