Default Help!

I am working on a 2-way which consists of Eton 800/37 woofer and Morel MDT30-S tweeter.
I actually got the design from Madisound.
I'm finding the tweeter quite dirty in the mids.
I would appreciate any help.

High Pass = 2nd Order
C1 = 8 Mfd
L1 = .4mh

L Pad
R1 = 5 ohm
R2 = 10 ohm

Low Pass = 3rd. Order
L2 = 1.8mh
L3 = .5 mh
C2 = 15 Mfd

Woofer EQ.
15 Mfd
8 ohm

If Madisound designed it, did they supply you with a LEAP FR and impedance simulation as well? I'm not familiar with these drivers but that might help identify the shape of the response and crossover point.

When you say "dirty" do you mean voices or certain instruments are recessed or lack clarity? Is this more prominent at higher volumes? Does it get better if you move off-axis? (either vertically or horizontally)? Are you playing them in a highly reflective (or highly absorbing) room?

David.

I can hear it in the low range of the tweeter. It is almost as if the tweeter is set too low as a x-over point. I doubt that is correct but that's what it sounds like.
