About the Boston Acoustics SC65

Boston Acoustics SC Series speakers bring brilliant sound to your vehicle's audio system. Their precision construction and sensitive response allow them to deliver superb performance, filling your car with perfectly balanced sound and making your drive much more pleasurable.

Boston Acoustics SC Series speakers bring brilliant sound to your vehicle's audio system. Their precision construction and sensitive response allow them to deliver superb performance, filling your car with perfectly balanced sound and making your drive much more pleasurable.

The Boston Acoustics SC65 6-1/2" speaker features a tough copolymer woofer that really delivers the beat. A butyl rubber surround keeps the cone under tight control for clear sound and reliable operation even at extreme playback levels. The 3/4" Kortec® dome tweeter sits in a contoured baffle that widens the dispersion of your high notes, providing clean, well-balanced instrumental detail throughout your car.

A built-in crossover makes sure the highs and lows combine smoothly, and protects the tweeter from sudden overloads. The compact neodymium magnet helps reduce the size of the SC Series speaker, so it can fit in more vehicles without any loss of fidelity.

Note: The oversized terminals on these speakers won't connect to a Crutchfield wiring harness. We recommend that you buy a 10-pack of female quick slides that you can splice onto our harness.

Features

Tweeter: Each speaker uses a type-S2, 3/4" Kortec dome tweeter. Kortec is a silky fabric saturated on the underside with a proprietary stiffening agent. Because the inside surface of the dome is ultra stiff, the tweeter tracks the signal with ease and produces an excellent transient attack. Simultaneously, the soft, self-dampening top layer eliminates unwanted resonance, so the sound is smooth and articulate. The Contoured Asymmetrical Tweeter Baffle (CATB) delivers smooth extension and strong on-axis and off-axis response.

Woofer: The copolymer woofer cone has a durable butyl rubber surround and stands up to the harsh automotive environment.

Crossover: All SC series speakers feature specifically tuned crossovers to deliver the best blend between the tweeter and woofer. Each also features tweeter protection for optimal performance and reliability.

Voice Coil: The oversized 1-1/2" voice coil increases overall power handling and reliability.

Installation: The compact size of the magnet allows SC series speakers to fit where other high quality speakers don't. Neodymium magnets offer extraordinary power-to-weight ratio, approximately ten times the magnetic strength of a conventional iron-ferrite magnet of equal size.

VariMount: The Boston SC65s come with several mounting adapters, making it possible to drop the speakers into the most common factory locations. Both 6-1/2" and 6-3/4" adapters and 7⁄16" spacers are included.

Speaker Terminals: These speakers have 0.25" positive (+) terminals and 0.187" negative (-) terminals, which are too large for the vehicle-specific speaker harnesses supplied by Crutchfield for many vehicle applications. It is recommended that a pack of assorted female quick slides (item # 120FQS10PK) be purchased and spliced to the harnesses to adapt them to the speaker terminals.
