hybrid p a speakers

[bruce ferrara]

hi,
Anyone have an idea about a diy p a "type" speaker?
Of course I can't just be normal and buy a commercial set.
I am a guitarist and want to build a set of speakers that I can use with my amp modeler for small jazz gigs. I use this stomp box when I am touring and play through the p a. It sounds great and is versitile (don't tell my amp tech who did a ton of mods on my class A tube amp).
I want to make this small and full range so I can use it for a synthisis project I am working with. Also P A speakers don't really cut it with fidelity.
My idea (tell me if I am crazy) 2 8inch woofers like maybe the dayton classic, a 5 /4 mid and 2 small tweeters . This could give it a small footprint for small cafes and just be loud enough to cut a small gig...and I could play snthisized music through them at moderate levels..
I hate to go with regular p a speakers..What do you think?

I believe that to do PA, you use PA speakers. That's what they are built for. Hi-Fi drivers aren't up to the task. Do you have a design in mind?

Hi thanks for th reply.

Well I want to build this small...or at least a small foot print.
I am thinking muliple small cones rather than the typical 12 or 15 inch two ways that are everywhere. 4 6/12s per speaker? 2 8s? 2 10s?
This would make them at least narrow so they can be on a stage in a cafe and mabye have enough surface area to move a little air.
The tweeters are a problem with professional speakers. They are harsh I think..Any suggestions?

The higher the frequency, the harder it is to integrate multiple units. Four woofers are ok but you'll want to stick to one tweeter. If you use 4 - 8", they should go high enough to XO to a tweeter. I'm short on time this morning but can have a look at units when I return. Have you browsed through any online catalogues yet?

This 10" Eminence Legend B102 is used in a "highend" speaker(modified)
With 4 of them in an array with tweeter(horn) you will get a relative small footprint, good efficiency and power handling and maintain 8ohm impedanse, and I suppose with ok fidelity

Dont even think of a 3way

BTW, there is also ToneTubbys with 16ohm so you can paralel a pair and still use tubeamps - they are designed fore "open back"

I'd say make a WHW with two good 10" woofers, and a good high/mid horn. 10"ers in my opinion offers the best compromise between sound fidelity and sound pressure. You might have to augment it with a subwoofer though, and for that I'd recommend two push pull coupled 15"ers with a wave guide front.
