Horn tweeters recommend...

ecl86 · 10th May 2007, 12:17 AM

Hello,

I am a newbie here and looking for some advise for a pair of open baffle speakers that I am putting together.

I am thinking about the Eminence Alpha 15 (I am open to other recommendation for woofers as well) for the low end and some compression driver/horn on top using simple 1st order crossover at 1600~2000hz.

Can someone please recommend some inexpensive drivers/horns or large piezo drivers that sound reasonable good. My budget is $100 for the horns/drivers, etc...

I know that I can get the SI from Hawthorn for $300 a pair but I like experiment, monkey, tweaking instead of just buy and plug-n-play.

Thank you in advance.

Hi.
Here's one:

Cheap, gets down to 2K and 100dB efficiency.

$100 would be rather a rather tight budget for even a single compression driver capable of decent upper midrange let alone two drivers and horns.

It is my opinion that if you are going to do OB you should run a wide range direct radiator (i.e. cone driver) up to at least the first or second overtone of most instruments and all voices. So I would be looking at running the Alpha up to the 60 to 100Hz range and using a WR 6 or 8 incher for everthing north of that. If needed I would use a helper tweeter only above 10Khz. That tweeter could be fired to the rear or side to smooth out the high end. Something like the Pioneer 8" dual cone (about $25 per side) and a nice $10 tweeter on each side. You could use a Peizo horn for the helper tweeter if crossed high and carefully implemented but unless you are filling an auditorium I see no need for a horn in the midrange.

Now having said that the SI does cross in a horn at a pretty low frequency but that is a coaxial design and it would be very difficult I think to duplicate that effect with your budget. The eminence compression drivers available to us are not known for smoothness and would be pushing your budget pretty hard anyway.

Just my two pfennig.

Mike,

Thank you for your suggestion. Sound like I may have to go with the SI after all.

Best Regards,
