ugly as they are, the NS10's are a challenge to make the mix sound POGI. the LF is on the NS10's is a challenge, too - we usually use it to reference the mid 2K and nearby freqs (+/- ). As for KRK's, I've concluded they are bass heavy speakers - I have a pair of V6 that has a scooped 2k.
Anyway, my research is leading toward Brystons. Ouch!
