Step up to a new level of sonic performance with Sony XS-GS1621C 6-3/4″ component speaker system. The package includes two 6-3/4″ woofers, two 1″ dome tweeters, and a pair of outboard crossovers. Each woofer features a rigid, reinforced special Kevlar that delivers focused midrange and strong midbass punch, even during high-volume playback. A tough rubber surround supports the cone, so this speaker will stand up to the inevitable abuse that awaits all car speakers.
And if you crank old favorites through these speakers, the separate 1″ synthetic fiber dome tweeter will reveal the natural detail that your factory speakers couldn’t even hope to reproduce.
Tweak away
Included external 2-way crossovers allow you to get cleaner highs and fuller lows by sending the appropriate frequencies to the woofer and tweeter. Sony also provides two mounting options, so you can install your tweeters closer to your ears to achieve the best possible sound staging for your car. With that kind of powerful imaging, you might find yourself taking the long way home.
They look good too
If you’re planning on a custom installation, Sony includes refined, black grilles for seamless integration into most car interiors. Sony has also reduced the overall mounting depth, making this system a great fit for more vehicles. These component speakers are protected by the GS Series 3-year warranty, and they’ll handle up to 75 watts RMS – so go ahead and rock out.
Woofer Cones
The XS-GS1621C woofers use an MRC cone (Mica Reinforced Cellular glass fiber composite) with Kevlar to reduce weight and increase rigidity, delivering full bass response.
Rubber Surrounds
For a smoother response and improved durability, each woofer uses a rubber surround.
Tweeters
The tweeters are 1″ soft synthetic fabric domes. They can be flush mounted, surface mounted, or surface mounted at an angle using the included housings.

Crossovers
Each crossover has high-pass and low-pass outputs with a 5 kHz crossover point. The high-pass slope is 12 dB/octave and the low-pass slope is 6 dB/octave. A switch inside each crossover allows you to set the tweeter output level according to your system requirements and personal preference; choose 0 dB (factory setting) or -3dB. The inputs and outputs are screw terminals; they will accommodate bare wire or spade connectors up to 0.315″ wide. There are two mounting holes in the base of each crossover.
Crossover Dimensions
Length: 4.75″
Width: 2.7″
Height: 1.2″
Mounting: The speakers can be easily mounted in a variety of 6-3/4″ applications. Given the required cutout, they will also fit into the opening for a typical 6-1/2″ speaker (approximately 5″ diameter) but the screw hole pattern is larger than a standard 6-1/2″, so new holes would have to be drilled.
Bi-amp Inputs
The 2-way crossovers have separate inputs for the woofer and tweeter; this lets you drive the system with dedicated power for the separate speaker elements, instead of sharing power. If the system is powered using only two amplifier channels, the woofer and tweeter inputs should be shorted together.
