The Cullen people are evidently heavily modifying the analog output stage, but leave the digital front end alone. Walter said the cost of the digital mod and its return were not worth the money.
He went on to say they are still building their own crossover that will be used for both the CS2 and CS1. The custom XO will be essentially two behringers in a custom case with both RCA and XLR connections. Walter indicated the main drawback is not the construction of the Behringer but its processing power.
He compared a 486 and Pentium processors. No matter how heavily you tweak a 486, the Pentium will always outperform it. Or, in the case of videogames, its not that programmers have gotten smarter in the last ten years, it's that they now have more powerful equipment that empowers them to create substantially more impressive environments and gameplay.
As it is now, the Behringer is being pushed to use 98% of its processing for DSP. With the power of two Berhingers, Clayton will be able to further tweak the speakers to achieve results that substantially outperform anything available by way of a mod.
This is exciting news and makes way more sense to me given the nature of the technology.
