Speaker Management

It depends on the compressor, it's all about the time factor

peak compressor will activate instantly if the voltage gets above a certain threshold.

RMS compressor will compute RMS value over a period of time, and will lower the signal for a certain period of time if the computed value exceeds the threshold.

pseudo-RMS can be achieved with peak detection + long time constants (ie attack set  to the min, and release set to the max) but that's not an optimal method

To much money to spend on a crossover that could suffer from poor quality components, just don't trust T-Racks stuff, the bits I have used have been a little better and more reliable than older berry (we all know is terrible, some get 3 yrs outta a DCX, many get 4 months before a solder joint or budget component fails) , but the jury's out on new T-racks until others have used and tested these new LMS products.

I'm sticking with an XCA for now, better adda than the 4 series XTA, we tested it at dBs plym uni, obviously the 5 series is still the bees knees, but tbf I'd rather aim towards an armonia setup
