Get RTA and set the band-pass of acoustic pressure form the channel identical.


Yes, I need to get one!  Although Bruce and my tech guy both advise that the RTA may cause more problems than it solves, without proper interpretation.

This coil is low pass filter over 1K and it has nothing to do with “impedance matching”.


Impedance matching is Bruce's description, not mine.  The crossover F is ~850Hz.

If your horn has 80Hz flare rates (or least what Bruce states) then 80Hz order high-pass it too high. I would start form ~40Hz to unload the LF form it. However, I would be questioning if it really were necessary. First of all this horn has back chamber that changes the rules of the game and marks the horn less sensitive to the overload the flare with LF.  Second, Bruce used the fairly low Fs driver in there with large trout that makes them to act at lowest cut off as the direct radiators…. I very much doubt the it would be necessary.


I was thinking that beginning the rolloff an octacve lower is better.  This confirms.  I will try both ways over the weekend.

Are you saying that S2 has not as good lower mid range than heavy and dirty EVM15L? Well, I disagree and at my taste you cut S2 too abrupt. Not to mention that you have it sitting in the 330hx horn…


One of my S2s is sick, and not singing.  There is resonance / buzzing around 1k.  Still working on fixing it.  So for me, the EV woofer really does sound better than the S2 in this range.  I am looking forward to fixing this driver, and hear what it's capable of.

Get rid the L-pad and move the Fane up on the slope. Try to run it with ~ 0.3uF

Rgs,

Great - I will try.

Thanks a million for the feedback.  It will keep me busy this weekend ;-)
