    It's 35 per channel at 8 ohms. You could use bigger. But it will play loud enough in your living room. I wasn't so much trying to make a sale as giving examples. There literally are thousands of options.

    So you have horns? Good.

    I might know of a pair of 808A drivers that need diaphragms. I'll check. The 808 is the same body as an 802. Great Plains Audio can put in new diaphragms.

    Amp wise I have a bunch of stuff, I'm sure so do others here. We can keep exploring options.

    I tend to have multiples of the same amps. Ill try and look thru what I have. There is a marketplace here where you can post your wants also.
    Here's an example of a used electronic crossover.

    dbx 223XL Stereo 2-Way / Mono 3-Way Crossover | Reverb

    This is the one I would buy if I were looking.
    Ashly XR22/12 Electronic Crossover | eBay

    Basically inputs, outputs to the amps, and set the knobs. You can adjust the crossover frequency and horn level. Not hard, may look overwhelming but pretty easy really.

    You didn't misunderstand, you're correct.

    Yes, horns should be delivered early may.

    Thanks for checking on a path for some drivers. I live in OKC, so GPA is local.

    I've since read some on the dbx, they seem pretty capable. I'll check into the Ashly units, I've heard of these before but have no knowledge.
    Thanks a lot for seeing what amps you might be redundant on, very nice of you to do so.

    It's been a long work week and my late night researching has been scaled back because of it, using my day off tiday fir a full recharge!

    Old guy, any issue running pro gear with my Mac 1900 as the pre?
    Thanks again, enjoy the rest of your Sunday!

    Think I'm going to turn the 1900 on and listen the evening away on some much smaller Altec speakers, the 890c Bolero.

    Have a good one,
    -Brandon

    Should not be any issues. Just need proper wiring.
    Looking like in larger amps I have 2x Altec 9444b. Mid grade units. Far from the worst. There are better but for more money. I could do those at a good price- like $150 for both.
    I have only one crown XLS402 300@8 ohms 450@ 4 ohms. Might work for lows with one of the D75 for highs.
    I would want to put anything on the bench before shipping. I'm 70 ish and still work full time so that would take at least a couple days.

    That's just what I found in 5 minutes or so. I know there's at least one Carver and a few QSC. Probably Saturday before I can do a real search. There are a couple of small pallet racks of audio stuff. I are a packrat.

    Old guy, thanks for getty back to me. I'm in no hurry and am interested in hearing what else you might come up with, if you don't mind digging.

    Do you recommend using like amps if I want to run the HF on one amp and the LF on another?
    Appreciate all your help, only 50 but understand working for a living.

    Old guy, some 902-8A drivers came up for sale locally, are these drivers decent ones?

    Thanks,

    Yup. They are good.

    The 900 series is an evolution of the 800 series. Basically, newer systems tend to use a higher crossover frequency. Compared to the 800 series, the response band is shifted upwards.
    I'd welcome other opinions, but mine is I would use the 900's from 1200 Hz up, where the 800's can be crossed lower. My listening perception is the 900's have a little more up top. Not enough to make me change to them. Lots of folks cross the 902 at 800 and are happy. I wasn't. IMHO the 802 is much heavier and works better at 800. But get other opinions, and the only way to know is try.

    My friend is dropping off the 800 series drivers tomorrow. He wants $100. But they will need new diaphragms, and he said the screws were covered in a horrid green powder. He trashed them. You will spend $200 or a little more to get them going.

    Old guy, this same person has 808-8A's also, all working as they should, for the same price.
    Will these do ok crossing at 500?
    Thanks,
