I don’t know how humid it gets in Boston, but I do know how humid it gets in my bathroom after one of my children takes a luxuriously long shower (the kind that sucks every last drop of even lukewarm water out of the hot water heater). Boston Acoustics’ new HH 460T2 is a “high-humidity and weather-resistant” single-point stereo in-ceiling speaker that includes a foam collar around the center post that protects the voice coil from dampness and a crossover that is covered with a special type of varnish to protect it from the elements. The speaker also uses the same type of binding posts found on Boston’s Voyager outdoor speakers, so they’re easy to seal with silicone after the wires have been connected. Two models are available. The HH460T2 is $275 each. The higher-end VH470 T2 is $450 each.
