The 807 is one of the small format 1" exit drivers. Do you have the horns and the drivers together?

Pics?

Use them from 500 hz on up with a proper horn. Some people cross at 800hz, 1200 hz; whatever. But you can go as low as 500.

As I recall the 807 used the high power handling Symbiotic diaphragm which most Altechies think is a little raw sounding and not quite as extended in the highs as the aluminum ones.

What I'd do with them is get some aluminum diaphragms from Great Plains. I'd get a pair of 811B horns for them and use them with model 416 woofers in a proper vented box. For a crossover I'd build a clone of the Model Nineteen crossover.

Values change on a daily basis. Check ebay.

Show us some pics please. Are there any numbers you can see on the horns?

EDIT: we need to see the horns to guess at an XO point.

Default ok

they have:

H-811B on horn part (metal)

and on driver:

807-8Z and 391132.

I have 2 of these.

got them for free. )

quite large.

i will try and get photos in next day or so.

need to find a nice 15in driver for lows now.

also i read about replacing the diaphragm on compression driver for one that has a smoother HF response...

any thoughts??

Geek----My advice is to crossover at 1200 hz using the Model 19 crossover. That crossover EQs the compression driver for extended high frequency response.

Get aluminum diaphragms from GPA.

Use an 8 ohm Altec 416 woofer.

My advice and opinions.

I like Tom's advice. The 811B is the "small" horn in the Altec line, designed for 800 Hz and up. The 416 woofer is a good match. I think you could use the 515 woofer as well.

Great Plains does an overhaul service at a reasonable cost which includes new diaphragm, gap cleaning and magnet recharging. There are many aluminum diaphragm choices but Iíve heard good things about #34647. http://www.greatplainsaudio.com/PartsList.html
