It bothers me there is no sub control. Makes me think you have to buy their pre.I think the plate amp get a high level signal from the speaker terminals, and the xlr connection (room correction) may have something to do with this I found on line.
And there’s a passive xover illumination lamp switch, so you can see it through the side grills??, how tacky.

"The bass section is powered by 1,000 watts of included ICEpower® amplification and offers exceptional extension to 18Hz.
The included 24-bit DSP room correction features balanced analog inputs and outputs for optimizing performance. The upper portion of the speaker cabinet is open air dipole for fast decay of mid-bass frequencies and airy spacious highs. The elegant design employs a 2.25” thick baffle with 2” side walls. LED Crossover Illumination within the upper portion of the cabinet reveals the intricately wired crossover design."
