Re: excessive highs customizer

Ron,
Sounds like the tweeter sensitivity may be poorly matched to that of your mid & bass driver. to really get a nice sound (not just flat) your bass should be slightly (maybe a couple to few dB) louder than your mid/high section.
Check the sensitivity spec of each driver in the system. Chances are you will find that the tweeter is way more sensitive than your mid/bass drivers. If thats the case you can calculate a series resistor to put in line with your tweeter to tame the sensitivity level.
At most, you might spend up to $15 of parts and an hour soldering. I have the formula in a book at home, if you are interested in trying it I will check the post later & update after I get home and look it up.
I wouldn't really recomend an L-pad unless you want to drop some serious money (the cheap ones vibrate too much), but they can give you a variable resistance to play with to tune your highs in "by-ear" although it still takes the same caculation measure to find if you might need a series resistance inline with the L-pad.
The bass response can be varied by moving your speakers into or out of compression/cancelation nodes in your room.
Take it easy & let me know if you want to take an electrical approach to the problem.
