WTB KPT-? in Garage Sale Posted June 29, 2016 In the older lines prior to AW, the KHO7, the patio mainstay, is basically the same box and drivers as a KSB1.1, of which I have several pairs. Love them, they sound very nice, and have plastic cabinets which don't self-destruct in the rain/humidity. I do bring them in during winter months and keep them sheltered from driving rain by installing under the overhangs of the house. You might try something like that.
