Boston Acoustics S65

S Series 6-1/2" 2-way Speakers (S-65)

The Boston S65 6-3/4" speaker features a 3/4" tweeter with a built-in
cooling system for long term reliability and excellent power handling.
A contoured tweeter plane guides high-frequency output to create a
larger listening "sweet spot," while Boston's Amplitude Modification
Device (AMDâ„¢) reduces harshness in the upper mids for clear, detailed
sound.

The sturdy woofer cone teams up with a durable butyl rubber surround to
produce tight, clean bass with minimal distortion. And you'll hear a
smooth blend between the woofer and tweeter, thanks to the built-in
crossover.
