Can anyone recommend a source for a pr of 1.4 to 2" adapters?
Google led me to a Parts Express page for a Selenium part but it appears to be obsolete.
Any advice appreciated!

Altec 33710 Altec Lansing 1.4" to 2" adapter. Not Cheap.But nothing is from this particular seller.
Altec 33710 1.4" driver 2" horn throat adapter EV JBL | eBay
Thanks for tip. H'mm...not cheap is right.
I like the fact that they are smooth machined instead of roughly cast like so many ALTEC parts but the price is more than I prefer to shell out for this particular experiment
I think I found a place to get adapters at a fraction of that price. Ordered a pair. I'll report back on the details when I get them.
Let us know -- I was in a similar situation a year or so ago, when an AA member offered to sell me a pair of the Selenium adapters at a nice price. Another guy said he could make a set out of wood for a reasonable price. You might find the thread with a site search of the High Efficiency forum.
Worth checking with GPA- I know Bill makes some of the adapters again.
Closest I know of otherwise is Paudio, but it's 1.5".
Martin Sound in Cleveburg has it.

I ordered a pr from Martin Sound last night. Will post pics when I get em.
Did the martin's work? Looking at the diagram, does not seem they are pre-drilled for 3 bolt setup.
but if they worked... I may go buy a pair...
cheers!
* I see GPA is making the 21216 / 21216A , praise to them! Anyone know if they are making/planning a 33710?
I never even unpacked them! I will tonight and provide pics/measurements.
So this would be running the adapter "backwards", right? Normally it's meant to put a 1.4" driver on a 2" throat horn, isn't it?
That's what I was intending. 288 on HP1240.Quote:

Of course, they were in plain sight...still in boxes, in use as feet for a Garrard 301 turntable I'm working on.
What a retard, huh?:p
This is for Martin Sound PC-5308
Small aperture is 1.5" not 1.4"!! 4 bolt pattern on 4" circle, look to take a 1/4" bolt.
Wide aperture is 2" 4 bolt pattern on 4" circle and the holes are THREADED. Shouldn't be a problem because most horns have bolt holes rather than captive threaded studs.
Not sure of thread gauge but a click or two down from 1/4"...maybe even metric!
Length of adapter is just under 2" so the flare rate is quite fast.
From the looks of these they would be more appropriate for EV 1.5" drivers than 288s, sadly.
Excellent report, thanks!
Was considering drilling them out for 3-bolt, but then I've got to buy a working drill press (well, it'd be wise to), build a template (not bad) etc.
That's fine, but the 1.5", and a time constraint maybe tipped me the other way.
So I've anted up and ordered the $ 33710's off of ebay.
I'll take a look at the apertures with the digital caliper to see how they measure before bolting them up.
Nice, machined units, nominally within 1/100th of 1.4 and 2.0 aperatures. Some pics...
Now, I've stumbled across the right martin, check it out:
M-3825 Adapter, converts a 2″ exit horn lens to accommodate a 1.4″ exit driver Martin Sound Pro
Hey, that looks an awful lot like the one I bought!
You might want to verify the actual size before ordering. I measure 1.5" on mine. Part number on the box was PC-5308.
Actually I checked the invoice and I supposedly got shipped M-5038, which is a 1" -->2" adapter.
I actually forget what I ordered (maybe I did order the 1"-->2") but they don't even list a 1.5" in the catalog--and I wouldn't have bought one if they did.
Here's a pic. Parallax error of photo makes it look like it comes in under 1.5" but it is spot on at an inch and a half.
