I'm looking into designing a wide dispersion HiFi PA system using two 10" midwoofers and the 18sound AMT200 or similar PA type AMT driver with a horn or waveguide. 18sound offers the XMT200 horn for the AMT200, but this is designed for a 90° horizontal coverage, and I want a wider coverage, ideally 120 - 130°. I'd aim at designing a box that has such a wide - and continuous - dispersion even at the crossover point.
Does anybody here use the AMT200? With or without horn or waveguide? What's your experience?
Are there any alternatives? I know Beyma makes a couple pro AMT drivers as well, but their FR doesn't seem to go as low as I think I will need for a crossover frequency that would allow a perfect coverage match to the 10" woofers.

Seems like a nice driver, but if you use 2 pcs of 10" woofers, why not use two 60 degree boxes with a one smaller AMT in each?
