It's not really a question of saving up -- in the USA tradition, anything I buy will rack up interest on a credit card -- but rather the inverse correlation between system cost and WAF when the time comes to order (hopefully next month!).

It's not just the $300 difference between outlet M60's and M80's, but also the need for a more powerful amp to handle the 4-ohm M80's, which makes it more like a $900 difference.

On a tangent, I wonder what makes the M60 with three big drivers 8-ohm but the VP150 with three big drivers 6-ohm. One would think they'd both be the same. Or are these impedance ratings kinda rounded?
