It would depend on the room you have - how big is it? The MANTARAY horns are quite large...

If you do this, you'll no longer have an actual A7 - what you will have is an A5.

Actually, it would properly be called an A5A/MR94 (if you were using an MR94).

The driver would have to be the larger format Altec model - the 288 or 299 would work best.

The A5 only works well in large rooms...

If you want to use the A7 with a Mantaray horn, the only one that would be proper would be the MRII594, which is a 500 Hz style, 90 x 40 Mantaray designed for use with the above mentioned drivers.

well the room is 13 by 22 but i just love the way those look and what about the crossover oh by the way i see your from sapulpa im in tulsa howdy neighbor

They'd be pretty BIG for that sized room, I'd think - I'd go with the A7/MR994 (A7 with a 902 coupled to an MR994 90 x 40 Mantaray horn) if I were you.

Crossovers for the A5 are 500 Hz, and 800 Hz for the A7.

Angel,

The large Mantarays are really designed for use with the larger 210 enclosures used in the A1, A2, and A-4. To properly phase-align the horn on an A-7/A-5 box would require the front of the horn to be several inches in front of the enclosure. It would work but wouldn't look very good. I would just use the smaller MrII-594 with large format driver or MR994 with small format driver.

I have the same horns and am using 291 16 ohm drivers.
The tweets are MR1602 and the base is a pair of 816 cabinets, sub is 8182. Separate amps, total power 2.5 kw.
Hi-Fi doesn't get any better if you like live concert videos.
Anyway the 291's are worth it.
