High Efficiency PA System
 

I am looking to build a PA system for parties etc, I would like to build something fairly robust with high efficiency (95db+, 100db ideal) any projects worth looking at or driver suggestions? Budget is about 800AU max.

How big?

One 15" woofer and a horn tweeter? Or do you need more than that?

Are you looking for efficiency or volume? I believe that there's someone on the forum who built a PA that sounded pretty darn nice out of NSB's, might be worth considering.

I did a sub sat system with a 15 sub and two 10s and horns.
I needed the coverage of speakers in the air but the nice bottom you get from putting a sub on the floor.
it turened out sounding ok with 2 pro amps one in bridge running the sub and the other one powering passivly crossed tops.
Had I done it today i would probably run 12inch drivers rather then the 10s for the tops.It just sounds a bit thin when you are close to the sats and at a distance from the sub. Or heck why not two 10s and a 1 inch driver.
i would recomend against a 15 inch and a 1 inch because of the problem you will get in the upper midrange.Maybe a 15 and a 2 inch crossed low but then youll loose out on the really high frqs.

You could check out adire audio's HE 10.1, I have not heard it but the reviews of it have been good and it meets your requirements.

Id go for Paudio bits as their easily available. You can always order through shanghaiproaudio if you dont like the cannonsound prices.
