Awwwww Cmon Uncle Dave....That Mackie Sub is only 100 lbs plus a wee bit more...your back get tired????? I'm still keeping alieve and Doans in business.....let me know what you think....anything to lighten the load would be Great!!! I have to admit..I'm still running the EV's and the Mackie Sub and the more I play with them, the better I like the sound...I have yet to run the Sub with more than a quarter Gain....the EV's I run straight up and down....and I have been playing bigger facilities lately....The folks have commented plenty on the sound quality....looks like I'll keep them till they quit...which leads me to ask...How long can one expect these powered cabs to work and sound good...I realize "it depends" is the right answer, but keeping them in a clean dry environment, and handling them with kit gloves, and keeping the sound level conservative..30-40 dates a year....is 5-7 years reasonable?? enjoy the lighter Load Brian
