The ETX line is manufactured in a few different spots. The amplifier and DSP module is made in Germany by EV. If you don't know, EV is owned by Bosch, which also owns Dynacord, Telex and RTS Intercom.
The woofer and HF drivers are made in Bosch's facility in Mexico. State of the art facility made two years ago.
It's all shipped and assembled in the US at EV's manufacturing facility.
They chose the IEC locking connector over powercon because IEC is readily available. Belive me, I left my powercon cables in the shop and went to a gig hours away, it took me 2 hours to find a shop and rent them. Not fun. If you're dying for powercon, wait until InfoCOMM.
The combo XLR/TRS jack, I really don't see why that's not professional. It's made by Neutrik and robust as all ever.
Don't think this is a run of the mil MI box. These were designed for professional production and install. The drivers are from our upper end installation and production loudspeakers. The subs use the same drivers from Phoenix series and are actually a step up from the X-Sub. The main speakers use the same components from the EVF installation boxes.
The amplifier is a brand new Class D design and the DSP chip is the same module from our Netmax and DX46 production DSP frames.
Very high quality. Worth giving a listen.
The subs have a cardioid setting for easy setup when using that configuration. Adjusts delay, phase, and EQ all with a switch. There's a 30 db loss on the back side. It's impressive.
