PA mids + Impedence mixing question

[AllenH427 10]

Well, I'm going to need some PA mids to blend with my crescendo supertweets.

I'm looking at these, they are 8 ohms. My plan is to split the power of my rear two channels of my Arc Audio FD4.150. It's rated 160 per channel at 2 ohms. I currently have Type R 6x9s on them, and I wish them to remain on the channel. Assuming I hook up 2 of those Selenium mids + a type r 6x9 per channel, the amp will see a two ohm load correct? 1/(.125+.125+.25)=2. And each speaker will be receiving ~53 watts (of course not continuous) correct? This seems like it should work but I'm not positive...

It will sound like shit. You NEED a crossover with those and preferably before the amp. Same with the tweeters. The 6x9's on the hand don't need one.

Bridge the amp to the 4 selenium mids. Same power as 2 ohm.

Run the 6x9 on the HU if you have to have them. You wont hear them over the Seleniums that is a fact.

I have a different amp for the tweeters and I'll use the HPF for them... and where could I find a crossover for the PA mids then?

[Sir-Lancelot 216]

You are going to want a crossover that will bandpass those mids.

Either a HU or an external 3way with bandpass.

You could find a Coustic on the cheap that will work if you look around.

Since I'll have both mids wired in parallel, can't I use one of these per 2 mids?

Not really. "can" is a hard word to respond to. If you don't care how it sounds then fine...err sort of.

The mids will then be set from 80hz-5000hz, whats wrong with that

And the tweeters will be set at 4-5k to up
