A contrarians speculative view of the new redesign:
It's black, finally!
It will likely be very slightly quieter in stock form
*Impedence adjusting for those using these for full range operation vs just subs.
Looking through the PDF, they have not updated or changed a single thing on the inside* (or even the outside, with the exception of cosmetic differences). You are still buying the same amp and DSP solution as before with zero updates*. To me this means no adjustment under 20 hz, which was a popular request around here. Even upping the PEQ count from 8 to 10 would have been a great update, but nada.
The fans will still be the same loud fans, with the same "variable speed control" as before, which is programmed with the same logic as before: -start cold at the loudness of a lawnmower, then if the unit gets hot, boost up speed to jet engine level. You might not be able to hear the fan quite as well as before because they closed up a large area of the front panel. The small gaps for ventilation on either side of the display have small holes. This means it will be hard to clean and will always look dusty. This unfortunately means very much reduced air flow as well. My guess is that there are no aerodynamic guides inside the chassis to guide airflow, and no added heatsinks for sure, as those would surely add a lot to the production cost. So basically it will likely be a slightly less noisy but vastly less capable cooling system. The conclusion I can draw from that is that it will no longer be a viable solution to fan-swap, as you'll just quickly cook your components. They seem to have fitted larger rubber feet on the bottom to compensate, as these amps have always been heat sinked to the bottom. Maybe the forum can start a crowdfund for a large finned heatsink made of powder coated aluminium that would screw right on to the bottom in place of the feet?
They did away with the handles. The handles weren't there so that you could do bench presses with that 12-pound monster. They were there so that if something touches the amp (anything from an overly enthusiastic groupie, to a labrador in the livingroom, or moving furniture when you're vacuuming), it doesn't touch any buttons or worse, snap off your knob!
The new interface is much nicer looking for us home theater folks, but looks much more fragile. The black coating (probably cheap paint on the metal panels) will certainly scratch quickly and easily. YMMV, but to me these don't look anything like the go-anywhere, do anything "beat on 'em who cares" workhorses they replace. I really wonder how popular these will be in the professional market.
The LEDs are cooler-looking, but much less useful. The previous amps had LEDs indicating power levels of -24 dB, -12, -6, clip/protect. The new one has indicators for -40db, -6, -3, protect/clip.
They reduced the 4 ohm power claim from 3100W to 3000W. Is this Behringer being slightly more honest or did they really reduce power output?
One step forward, two steps back.
