I have two pairs of prototype open baffle frame builds. Both pictures show front view (left) and rear view (right). Both constructed of 3/4 void free plywood with maple unfinished maple veneer. The front woofer and midrange cutouts are rounded over, designed for rear mounting. The tweeter cutouts are plain through holes. Design was CNC cut. Some screw holes to test/mount drivers. Surfaces are unfinished but lightly sanded.
Prototype 1: Designed for Dayton AMTPRO tweeter, Seas FU10/MU10 midrange, Peerless 10" SLS woofer. Other combinations might work.
Prototype 2. Designed for Vifa XT19, Seas FU10/MU10 midrange, Peerless 10" SLS woofer. Other combinations might work.
Cost is $100 per pair, plus actual shipping. (will ship to US, lower 48 states only)
Thanks for looking!
