How does that present a problem if the sub has its own amp with,
presumably,
a volume control?


No, I mean it is a problem when you share the main speakers' power amp
via a crossover. With a plate amp all problems vanish.


OK, that's what I thought/hoped, although I'm not out of the woods yet - the
dual driver design appears to be suggesting one sub per channel which I
don't think will work from a 'standard' plate amp....??

No worries, I'll sort it....


Frankly for a sub you may as well mix the two channels to mono through
a couple of resistors. There really is no directional information down
there. Then one plate amp will serve the two drivers. Also positioning
one sub is hard enough - when you have two the problems are far more
than double.
