Eminence APT 200 Super Tweeter with Bi-Radial Horn 90 x 90
What would be a good woofer companion?
Sticking with Eminence products, what would be a good "natural" match for this horn? Small venue SQ system looking for no bigger than 12" woofs... THANKS!!!
Balance performance with budget. Is those for a studio monitor, home use or sound system. I would choose differently for each. A venue could be coffee bar or neighborhood bar. See below.

Given the high efficiency, has anyone used this horn with a low power tube amplifier, 10-20W?
I've been looking at several drivers in the pro category for a monaural speaker setup for a 10-20W tube amplifier. Has anyone used this driver in that application? Given the high sensitivity and relatively low RMS power for this driver, it appears that this may be a good match for low power tube applications.
This unit is awesome at low power. It is open, transparent and clean from 5 watts to rated output.

Any technical information or real world observations on horizontal and vertical off-axis performance?
Am curious how directional these horns are, and how they perform off-axis both horizontally and vertically. I know many horns are designed explicitly to maximize horizontal off-axis response (within reason) but limit the vertical to control ceiling and floor interference. But I note the bi-radial horn on these and wonder if that may not be as true with this model? Is there any technical data available, or does someone simply have some personal observations? In my project, which is a high-mounted monaural cabinet radio, both horizontal and vertical off-axis response is desirable.
The 90 x 90 degree horn is designed to provide linear sound projections in both the verticle and horizontal plane. Because this is a sealed unit, box design does not influence dispersion. The true output will depend on your crossover characteristics more than the speaker. This item has a very flat responce across It's range.Measured output at equal distance away and off axis will be nearly identical less any influence by the ceiling or floor.

What is the rated sensitivity of the Eminence APT 200?
I don't see that specification in the general description or linked specification sheet from Eminience.
I think I answered my own question with a little more searching around. I found some specifications elsewhere that mentioned 105db sensitivity for this driver. The Eminence site and specification sheet however does not provide this information unfortunately.

How far does this horn stick out from the baffle if it is flush mounted?
It has been some time since I have worked with this amazing horn/tweet. My working drawing shows it as follows; the flange thickness - 3/8" and the lens lips - 3/4" for a total of 1 1/8".I routered a 3/8" recess for the flange allowing the 3/4" lens lips to be hidden by the grillcloth which was over 3/4" wood frame.I would call PE tech to be sure if this is critical to you design. If it is close, the sound is well worth making their dimensions work into your design
