Do active speakers have high THD amplifiers?

All active xover’d sound impressive at first, but then quickly always sounds sterile and thin to me in the end from the upper bass to treble, low bass is fine. I believe it’s because of too much electronics and opamps in the active xover that the signal has to go through
Every time I’ve put my Martin Logan Monoliths (with Neolith panels) through any type of active xover that’s what happens to them. Best sound is always 3rd order passive xovers for the panels 150hz up, and 4th order active for the 12" bass unit 150hz down.

I haven't noticed any problems with active ATC speakers. I don't own them, but have had long auditions. 

I know this OP if I couldn’t get the specs, I’d really REALLY doubt that I’d be buying their equipment. That being said. I don’t think active speakers or active crossovers are the best without some consideration.

Just like a passive XO requires GREAT parts and more than a little thought.

I use a First Watt Active XO that is chock-a-block full to the top with WiMa caps and Vishay copper resistors.. NO op amps in sight.. Has a switchable step baffle that is pretty cool for OB bass boost..

I also use 2496 actives from Behringer. 300 hz and down.. with 12K Class Ds directly coupled.. That is one of the reasons active speakers have better bass driver cone control..

Directly coupled to the drivers vs going through a passive OX. There is NO DAMPENING with a passive. An inductor or cap in the way. It can’t physically work.. Only the return springs on an active drivers.. Short internal leads and active XOs make for good bedfellows..

Again, parts quality, BUT the size of parts on the active side are MUCH less expensive because of the much smaller values..

Krell actives are 5-10k.. LOL they sound good..

See I pay attention George. I’m not just another pretty face :-)
