They used to be made by Square Audio, a local company here. The original design was called Square One, you can read some fluff here. Now the manufacturer became Reflector Audio for whom I used to work. They had some leftover materials so they could make me a pair of these. The design is very similar to the OG Square One, but the tweeter, amps plates and horns are different. Each of the boxes has a FaitalPRO HF1440 tweeter in an 18sound horn crossed over at 1kHz to 4x ScanSpeak 15WU midwoofers. The amp pack is a Hypex FA253 and all filtering is done via DSP. This makes the design point-source, controlled directivity and very much impulse-coherent as drivers are time aligned. I AB'ed these against my old Neumann KH310 and they decimated them. So I sold the Neumanns and upgraded.
