Hi Wayne,
  Thanks for your JBL 2245 suggestion.  Is there a little cheaper Eminance alternative ? Or can used 2245's be found.  Also, the Pi 4's already take up alot of room, so I'd like as small a solution as possible.  Right now I'm using a pair of powered 10" subwoofers that go under my BESL series 5 monitors (Bamberg engineering sound labs).
Not bad sounding but alittle sloppy sometimes.    And yes, I've corrected the tweeter crossover circuit.  I forgot, it's been awhile. My Pi 4 and Parabee combo sounds wonderful and keeps sounding better as things breakin.  
Tom
