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.
Tweeter Mounting Dimensions:
| ||Frame Width ||Frame Length ||Cutout Diameter ||Mounting Height ||Mounting Depth |
|Flush Mount ||1.911" ||1.911" ||1.6" ||0.31" ||0.555" |
|Flat Surface Mount ||2" ||2" ||N/A ||1" ||Screw Depth |
|Angled Surface Mount ||2" ||2.25" ||N/A ||1.17" ||Screw Depth |
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.
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.
- 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.
Specification Note: Sony's rated power spec for the XS-GS1621C
is 75 watts (derived using IEC 60268-5 standards). They also list the CEA 2031
compliant RMS power as 120 watts. We've adopted the 75 watt rating simply because
it's the more conservative figure.
