What I don't understand is why, do you buy M80's and a VP180 and set it to small with an 80 hz cross over, because the sub will do a better job ???? That, just seems like a waste of money. Why not spend 1000$ less and buy the M22's given that your not even using the lower freq. crossover in the M80's. they have the same drivers less the woofers. anything below 80hz in the small setting is going to the sub anyways. Just seems like a waste of speaker.
