Hello. New to the board and to A7 speakers. Has anyone tried this combination of A7 500-8 with the 1224A powered crossovers? I'm really out of my territory on these, I know nothing about them.

"Powered crossover" is a bit inaccurate.
Amplifier/crossover combinations are generally referred to most commonly biamplifiers (two way) or triamplifiers (three way).

They work fine. The built in crossover in this amp is limited compared to modern crossovers.
Basically if you have them, try them. If you like them, use them. But don't pay tons of money for them. Newer amps and newer crossovers or DSP will sound better.

Thanks for the reply, old guy- it's much appreciated. I've been going over and over this trying to calculate a bang for the buck move. I've seen where DSP's are pretty affordable and almost infinitely tweakable. But I don't have the gear or know how to go along with it. It seems the 1224A gets me a ways down the road on bi-amping and at the maximum- 3 choices in crossover points for around $400. I'm on a tight budget and got a pair of A7-500-8's minus horns, and horn drivers and one N-501-8A crossover for $100. The 825 cabinets and the 416-8A drivers along with the one crossover are in fine shape considering they were built in 1974... I've a possible deal on horns and drivers - hopefully know more about that soon. A sort of blank sheet to start with, so I'm trying to sort it all out. I've read much on builds and some of them read like a descent into madness for the builder! I'm new to all of this, I've now bought 3 pairs of speakers in my lifetime and the first two pair all I did was plug them in. What have I gotten myself into?
Thanks again!
If the 1224a you are looking at is $400 it will cost you $800 for stereo. Medium quality stereo. You can do a lot better.
A crossover and amps isn't much more complicated. Folks here could walk you through hooking it up.
For instance I have a couple of Crown D75 amps, one would power those adequately for a living room. You don't need gobs of power. You would need horns. The crossover you have won't work unless you get 500 Hz (Altec 511) horns, with 803 or 808 drivers. Altec doesn't recommend the 806/807 at 500 Hz.
What's your budget for horns drivers and electronics?
A couple of good small amps and an electronic crossover may cost you less than a pair of the better passive crossovers.

There are decent amps available sub-$100.
A decent used electronic crossover about the same. So $300 or so there.
You should be able to get horns and drivers for $500-ish.
Don't get caught up in inflated eBay prices. Watch for deals.
A handy tool is searchtempest.com
You can search within a chosen radius for your area.
I found these in Norfolk Virginia: Horn speakers Altec Lansing H 811b with drivers - electronics - by...
Not Altec drivers. Caveat emptor. But that's not totally outrageous for a good pair of horns. ebay the Peaveys. You can see though, that is about half what ebay denizens want for horns.
