Mike,

Do not mix up latency problems of audio over ip and digital connections like spdif or AES EBU. In the latter one they do not exist if the end points are build the same, asrc or not.

I'm not talking about latency. I'm talking about clock skew between endpoint. IEEE1588v2 is the closest you will get to having a single master clock for all channels, only clocking multiple end points in separate locations. But of course this is only 1 of the several advantages.

You could get in touch with Hypex to discuss this.
I am not into DSP active loudspeakers, but my gut feeling is that
- building and tuning an active loudspeaker is not per se "easier" than classic passive designs;
- the difference between the different DSP platforms may become less important when the active design is not optimal to begin with.
These are mere tools; when not used properly they will not change game in speakers IMHO.

And these tools make it possible to perfectly dial in the crossovers using a GUI, rather than switching out passive components. It allows for perfect phase response, time alignment, room correction, and the multitude of other advantages of taking the passive components out of the signal path. But of course, you need to have the ability to use tools properly. Just like you do with anything.

Like you say: make it possible...
Next month I will visit Hi End Munich.
Curious if there will be more DSP active speakers on show than last year.
When so however, I am pretty sure that there will be bad, good and excellent sounding designs around.

Another option (although not feasible for these plates) to take advantage of IEEE1588v2 is to use the latest generation of SHARC 589 series DSP chips. They have the protocol built right in. So with a simple link cable between units, you can take advantage of the nanosecond clock skew sync, without paying any licencing fees to 3rd party AES67 compatible OEM board suppliers.

Only problem is you need to have the knowledge to program it.

You'll also need a special chair that clamps your head to appreciate your perfectly aligned system to it's full potential :p

Of course. You can give a man a Lamborghini, but this doesn't mean the car is poor if he doesn't know how to drive it. Same with a laser for doing brain surgery.

Sounds like old fashioned passive based systems. With advanced DSP you can tune the system for perfect sound from any listening position :)
