Yep the KW153's do have a pole mount, was surprised but glad to see. I'd think you'd want some heavy duty poles or large sub w/ pole to mount over. (not k-sub for example)
I'd like to hear the KW153 compared to a K10. I really like the sound of the K10, the crossover freq b/t the 10 and horn covers the vocal freq's well. My K10's just don't quite have enough get up and go to run with my LS800p's. (mostly vocal heavy music). I'd think the 153's would be a better match volume wise, sound as good b/c of the 3 way design, and look more impressive to the audience. I don't know how many times I've had bands say "dude you need to go back to the trailer and get some speakers instead of those little things" I always say, just wait until you hear it. Always get nothing but accolades after we're up and running.
