I was simulating the Fane S 8M in hornresp, your favourite program, and then I tried B&C 8PE21 and it was almost identical. Then I tried to simulate the 18Sound 8M400F and it went lower than both of them. Listening tests on youtube comparing the ...

hi Woitek. The K33 extend the bottom end by the high Q, to almost 40 cycles . Which is only ok if you work with passive XO on a single amp.  Well that's how they were designed. Having designated amps that allow you to steer the parameter or even bett...
