You said: 'I let my main speaker run full range (what it's designed for)'.

Whereas I would say ... if you use subs - then you get a better integration by rolling off the mains at a frequency that matches the subs' 'roll-on'.

This is due to several reasons:
1. distortion increases on any 'mains' at their extreme low end.
2. you reduce the load on the amp driving the mains, if you remove the need to deliver extreme LFs ... thus this amp can better service the rest of the frequ range.
3. and you minimise the frequ range where the woofers and subs overlap. (I use 48dB slopes for my woofer/sub XO.)

You also said 'my sub amp is on its own as far as volume is concerned'.

Whereas I would say the one volume control needs to control the volume of both mains and subs.

My miniDSP unit controls volume for all 6 of my power amp channels.

And re. 'the sensitivity of the main speaker and the woofers is different' - the miniDSP unit allows me to compensate for both:
* disparate driver sensitivities
* and different amplifier gains.

Of course, you need to use REW (or something equivalent) to get it sorted!
