Electronic cross-over on pre-amp out, to split signal to subwoofer and bookshelf speakers

@dcaudio ...Simple, this: more than you'll ever need even later
I've the Pro version, but the LE is cheaper, less if you opt for open box or used.

Source noted offers free shipping on some items, turn-around is quick, they are helpful, the warranty gets extended....yes, the learning curve is steep as noted in one review....
But in the process you'll get an education in the subtle art of a crossover.
The D series eq's are nifty, a future upgrade when I can get a 'steal this' $ drain. ;)

Enjoy whichever you choose, J

@dcaudio ...sounds like a plan to go forth with....👍  Simple first to test the potentials and stumble over a drawback or so...
Then the focus knows where to hear and how.... ;)

Good variable factors! J
