Woofer Cones: The XS-GS1621 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: Each speaker uses a 1" soft dome tweeter
for outstanding dispersion and clarity.
Bi-amp Inputs: The integrated 2-way crossover has separate
inputs for the woofer and tweeter; this lets you drive the speaker system with
dedicated power for the separate speaker elements, instead of sharing power.
Out of the box there are jumper wires shorting the tweeter and woofer inputs;
the jumper wires must be removed to bi-amp the speakers.
Crossover: The crossover point is 5 kHz and the slopes are
12 dB/octave high pass and 6 dB/octave low pass.
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-GS1621
is 75 watts (derived using IEC 60268-5 standards). They also list the CEA 2031
compliant RMS power as 110 watts. We've adopted the 75 watt rating simply because
it's the more conservative figure.
