Hi Keith,

I use a an external graphic equaliser with my setup having had only limited success with the KN7000 equaliser. When the 7000 first came out I found some sounds quite harsh. Sound level measurements in my situation revealed pronounced peaks from the KN's internal speakers around 100Hz and 6.3kHz. Currently the equaliser in use is a 10 band (1 octave) unit. I am considering upgrading to a 30 band (1/3 octave) unit.
Behringer make a couple of reasonably priced ones.

Cheers
Len C.
