M500's ANN Arbor CL

In a different world I would grab these. I literally have no room.

vintage hard to find set of 2 altec professional floor speakers -...

I've seen that very pleasant green somewhere before. Maybe they were on 'bay already?

"...they want $1,500 now they can run up towards $15,000 to 20,000 or even more I am only asking $1,150 out the door I think that is a steal for these I think they're worth 2,000 dollars now one cone has a minor punch rip..."

Hmmm. Yes, $20,000, maybe 19,000 with the "punch rip" - but only if they were hand built and signed by Al Teclansing himself.

The guy is obviously a dumbass. But I think worth asking price. Or I could stop posting stuff. Just because you don't want it doesn't mean someone else would not.

Considering it's a 500 Hz XO, doing a dab of Elmer's glue or similar + maybe a tiny piece of TP shouldn't be audible since the WLs < its effective piston, patch diameters will be rolled off enough by the XO point/slope.

One speaker, with an interesting history:

ALTEC LANSING M500 FULL RANGE SPEAKER SYSTEM 3154 MR994A 909 MAESTRO | eBay

i have the drivers and horns to make up a pair of these. the 909s diaphragms are 26420 pascalites. they look new.
This could be my next Altec build soon as i get moved into N Florida. House couple acres barn and no neighbors.

The secret to success will be finding the data to successfully clone the 630hz high power handling crossover, it's got some special shelving and HF protection.

I'd go here and save ALL images if you;re serious about the build: ALTEC LANSING M500 crossover - MES ENCEINTES ACOUSTIQUES

I don't think you'll find that info anywhere else.

Interesting! I've been calling them 500 Hz due to what the distributor said way back when they got a demo pair in and no one's ever corrected me :(, so wondering if it's adjustable.

3154s Fs rated at 25 hz
