LD Systems X 223

I have used quite a few of these in the past, I can safely say this one is by far the best in quite a few ways, ease of use, sound quality and size, mono/sterio is another good point, add the low cost, this active crossover is a great machine for even disco.

I find that careful selection of matching equipment load and impedances, from mic or instrument to amplifying and speakers, that chanel eq is not needed much at all, plus DSP seems to be helping too, but this active crossover is the jewel in the crown of my sound systems, much more control of my frequencies, full & rich sounds are now mine.
