The first Watt B4 x/o offers 1st/2nd/3rd/4th order (6/12/18/24 dB/octave) filters in 25Hz increments from 25Hz to 6275Hz. It is about to be discontinued, so if you want it better grab one while you can!
Why are the Infinity IRS, Reference 1b, Beta ect speakers passive on the mids and highs?
I would like to know why all of the classic Infinity's and most other brands use passive crossovers for the mid to high transition? I don't think it was for cost and that level. Is passive better? Has anyone compared both to know which is better?

Hi timlib The Richter scale crossover is changeable through a chip. I have lots of values for it. You can even make your own crossover point, they give a formula in the manual. The other audio control is not an epicenter, I made a mistake but it uses the same crossover as the richter so using the two I can get a 3 way at any point I want. I am glad you have some respect for the Nakamichi, I wasn't sure what you would think about mixing car audio .I haven't tried using 4 amps at the factory crossover points. If I do I will let you know. Setting levels isn't a problem as I have an Audio Control 3050A spectrum analyzer. I am still not sure using so much electronics in the signal path is the best route to go. I really appreciate your help. Marc |
