Woofer Cones: The XS-GS1720S woofers use an MRC cone (Mica
Reinforced Cellular glass fiber composite) 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" aluminum domes offering
outstanding dispersion and clarity. They can be flush mounted, surface mounted
using the angled brackets, or surface mounted using the flat brackets.
Tweeter Mounting Dimensions:
| ||Frame Width ||Frame Length ||Cutout Width ||Cutout Length ||Mounting Height ||Mounting Depth |
|Flush Mount ||2.442" ||2.442" ||2.027" ||2.027" ||0.474" ||0.919" |
|Flat Surface Mount ||1.848" ||1.848" ||N/A ||N/A ||1.478" ||Screw Depth |
|Angled Surface Mount ||1.846" ||1.992" ||N/A ||N/A ||1.570" ||Screw Depth |
Note: With any of the mounting brackets
the threaded mounting posts can be used to hold the tweeters
in place, this adds to the required depth (approximately
1-3/8" for flush mounting, 1-3/8" for flat surface
mounting, and 1-1/8" for angled surface mounting).
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 jumper 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 crossover has 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. The input jumper wires
are factory installed to short the tweeter and woofer inputs; the jumper wires
must be removed and separate input wires used to bi-amp the speakers.
- Length: 4.650"
- Width: 3.325"
- Height: 1.282"
Mounting: The woofers can be mounted in a variety of 6-1/2"
and 6-3/4" applications.
Specification Note: Sony's rated power spec for the XS-GS1720S
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.
