As 'craigsub' & I have both found out, Axiom subs 'Thumpp' & don't softly 'Umphh'. That's what makes them so 'musical' for want of a better term.

For music only in my fairly large area, I really like the 400s' 8" drivers with a potent 500 w/CH - they are so fast & articulate. Many out there will dispute the 'speed' of a sub driver, but I think that there is something to it. Unless you have a huge open area, 2 powerful subs (500, 600, or 800) should do the trick. Four would be nice & more costly of course.

Having said that, I am not using any 'LFE' settings as my Tube Amp has no digital skulduggery on board. The subs are driven from the Amps 'Speaker Out' Terminals to the subs' 'Hi Level Inputs' where my speaker wires are joined to feed the M2s. Levels are adjusted by ear to my preference which is not excessive.

For my HT duties in a different room, my 2 X EP-800s very nicely augment my M22V4s. With these beasts, I don't know if anything would be gained by going to Towers...
