Coverage Pattern of an 8" MTM

Re: Coverage Pattern of an 8" MTM

I wonder if anyone's tried building a 2x10 using this horn in-between them? - http://www.parts-express.com/eminenc...8-tpi--290-549

I've been curious about that horn for a while. Has anyone done any pattern-checking or listening auditions on these?

My one concern is that with the small size- how would it handle even 1000Hz (as stated minimum crossover point)? I'd definitely be inclined, knowing just what I do now, to NOT want to take it any lower than an E-wave crossover (acoustic crossover between 1500-2000 Hz or so).

Regards,
Gordon.

The consideration is that

center-to-center distance of about 12-16 inches, depending on the size of the waveguide that goes between them.

leaves between 4 - 8 inches. That puts constraints upon horn/wave-guide selection.

Here's an 8" MTM using a small neo-magnet tweeter, (the size is deceptive :eek
Didn't care for them inside the house, but they are keepers for party speakers.
Made tall stands out 6" PVC so tweeters are ear level.
Folks seem to love em, always looking for the volume setting, more, more!!

True, but my guesstamate is that the vertical pattern will be 50 degrees or so, and that combined with my fairly high crossover point should lend itself to a horn that's wider than it is tall as well as fairly small in general.

Can't say I've tried it : my concern is there could be a "hole" with a high crossover and a CTC separation of 16" which is a 1/4 wave distance for 210 Hz ( 90 degree out of phase ) and 180 degrees out @ 420Hz.
Are you planning on a passive crossover?
