Bose Speaker System

Carbon-injected plus one cones are larger than others in their size class, meaning they move more air and make more bass
Soft-dome tweeters feature oversized voice coils for greater heat dissipation and higher power handling resulting in smooth, fatigue free highs
The patented i-mount system allows unparalleled flexibility whether you flush- or Surface-mount your component tweeters
A dual-level tweeter volume adjustment helps compensate for less-than-perfect speaker placement, and can even be set to suit your personal listening preference and musical taste
Low-impedance, three-ohm speakers compensate for the undersized wires found in many of today’s cars, and make the most of every watt your car stereo can deliver
The GTO 609C’s Plus One carbon-injected cones provide more overall speaker-cone area than other cones in its class. With an effective increase in cone area, the speaker radiates more air. Also, its carbon-injected cone material produces a lighter and stiffer cone. The result is a better low-frequency response and a greater ability to make those important musical notes that people often associate with larger speaker sizes.
