My 2 X M2s + 2 X Ep400s driven by a 30 W/Ch tube integrated amp with no ability to EQ the sound in any way were quite easy to set up.

I set the Crossovers to 100 Hz & using a high quality SACD such as a Spyro Gyra track that has up front, dynamic & articulate bass content, I just progressively turn up the Gain until it sounds really, really good. Then back them down 1 notch or so & it is basically perfect for all well recorded music.

I haven't had to play with the settings ever since. Excellent system...
