I thought I had chosen compatible drivers but my buyout Foster meets Dayton neo dome array circles the drain. I chose the Foster woofers over the extended range drivers as the midrange looked a lot smoother. It all started out as a Tallerey, I then saw some pretty Dayton neo domes and went for it - a full 32 per side - without considering the challenges of the ragged response of these drivers near their frequency limits. In my desperation the cabinet grew wings, then a back. Even with an active crossover and tri-amping the combination doesn't work well. I'm considering putting a single Vifa DX25 and make a Foster powered quasi-ART array. I will save my Dayton tweeter line for another day. If that doesn't work well enough I could always build a full on ART Array but I wanted to salvage the behemoth I have already built. My question is (Fred can chime in here), will the DX25 work well enough to try it with my 12 sealed Foster 5 1/4" Woofers.
