The only BFM sub I have built was the TAT for my van which gives out
unbelievable loud and clean base with only about 100w feeding its 8” driver…
However, I am also a proud and very satisfied user of 6 of his DR290 top cabs.
I built them about 3 years ago and have been using them ever since.
I enjoy the versatility of configuration they offer, from two cabs on sticks - basic FR system
and up to (my…) big 3way setup with two or three DR290s per side on top of LABsubs.
They do fit perfectly the types of gigs I am doing and I really came to love their many advantages.
Their light weight, super high efficiency, fidelity sound (they do need carefully tailored EQ though)
their limited horizontal and very narrow vertical dispersion and their stacking (and hanging) ability.
Based on my humble experience (I also built an Omni 10.5 for a friend – now replaced with the Jack10)
I have good confidence that Bill’s other designs are as nice sounding as the ones I have tested.
I would recommend to those who haven't had a listen to a BFM cab,
find a
properly built cab in a
properly tuned and deployed system and give it a chance…
