OK, next step with the sealed cabs is amp with lower damping factor for fuller bass.....
Not much puff with the passive preamp so out comes the active....
Interesting to observe how the larger Tannoy systems Baffle Step freq sits below the average room Schroeder frequency. I'd guess this is why they don't bother with BSC.
A challenge but a fantastic project to have completed. The sound of these will blow you away JohnJo.
