Boston Acoustic's S series speakers let you enjoy clear, natural sound, even with a low-powered system. And with a wide variety of sizes, you'll find a set for most commonly-sized speaker openings.
The Boston S45 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 (AMD™) 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 midbass with minimal distortion. And you'll hear a smooth blend between the woofer and tweeter, thanks to the built-in crossover.
