My MK S150s are anything but silent!
I just got an MX350 MKII sub, great deal, it's a close-out model (I'm actually demo-ing it). Playing with it today. Walking across the room on the LFE waves! This thing sounds almost barometric! But it's now old tech, they have introduced a ponderous new sub line, the
SX series. Funny too, since the "K", Ken Kreisel, is also producing an even more ponderous sub line as
Ken Kreisel Sound. Check the Quatro-Quatro configuration...12,000 Watts continuous, 32,000 Watts True Peak!!! 4 stacks of Quatros! Gotta love the bass.
But M&K is alive and well, and the MX-350 II closeout probably won't last long.
