Is a B&K EX4420 a common ground amp?

Options
Just wondering if I can use this with the blade/blade SDA SRS 2's I'm picking up tomorrow.

    I just checked the B&K 200.2 that is replacing the 4420 in my main system tomorrow and it reads .2ohms on the 200ohm scale when reading from the l to R speaker grounds. It appears that it is a common ground amp, hopefully the 4420 is too. I'll check it once it's out of the system.

    If not I'll use my Halo A23, I just like that B&K amps sound. I could use my B&K ST2140 too I believe.

    It is. I've used my 4420 with both 1.2's and 2B's without issue.

    Hey, the search function worked today. How would this amp's sound signature compare to any other amps you've run on your SDA's?
