I've been looking for a second pair for a while and found a single for $300 a month ago on fleaBay but it wasn't packed well enough and the volume control was nerfed . I kept it anyways as I can jumper out the volume - I usually use them up full anyways.
Now I just "best offered' a pair that have always been bracket mounted so in great shape for $100 less than they were asking figuring they wouldn't go for it at $300 each shipped. "Unfortunately" they went for it and now I have four plus the "fixerupper" .
I do still have the "twofer" brackets from when I used to run two pair of PR10's so no more covering a thousand people with only one pair .
Yesterday was covering 150x150 feet outdoors, still a stoopid big space (over a thousand at 20 sqft each) and I only brought my 34 lb 2x12 "subs" . It was fine at "family friendly" volume though even though some were seated all the way in the back with maybe 300 in attendance. I mixed about half way back straight back from the SL "stack".
