HK Audio Elements Smart Base Single luidsprekerset
Anyway, back to the review -Expensive, but it really is excellent kit, with an excellent sound - clear as a bell vocals in a 4 piece blues/rock band - easily heard over a loud second-half classic rock set (when the beer has been flowing). I have used it in various wattage configurations in different sized pub/venues - no feedback problems (still set them up FOH and use monitors). My only worry is that a drunk punter can fall into them because they are unobtrusive.... I have insured them though in case the worst happens.
if I was doing an outdoor small gig or a bigger stage type venue, I would use the full set up and re-enforce them with another 1000w conventional sub and tops that I have from the old system.
If you want lightweight, high quality, you wont be unhappy - but they do cost a lot more money remember.
