A Seas Design
Seas Thor
The Thor is the new top-of-the-line loudspeaker kit from Seas.
It is a full range, floor-standing system that provides the very
highest level of acoustic performance.
The enclosure uses a newly developed transmission line configuration,
derived both from sophisticated computer modeling, and extensive eperimentation.
The line is tapered, and filled with Dacron (polyester) stuffing.
The two woofers excite the line at slightly different points, smoothing the
response and increasing the range of bass output. The trasmission line
produces 4db of bass liftfrom 20Hz to 110Hz, with less tehn 1db of ripple.
The -3db point is 45Hz, with roll of of 12db per octave below 45Hz.
Usable in-room response extends well into the low 30Hz range.
Frequency response 40Hz to 25KHz
Efficiency: 89db 1w/1m.
The tweeter is the Seas T25-002 Millennium from the excel line.
The Woofers are the Seas Excel W18E001 magnesium cone 6.5 inches.
The low pass filter is a 3rd order with a second order zero. An addition network is placed
in parallel with the woofers to serve the dual purpose of tailoring the frequency
response and removing the magnesium cone frequency peak.
The high pass network is a third order Butterworth with an additional impedance
compensation network. The X-over frequency is 2.5Khz.
The Odin mk3 was designed by Dr. Joseph D'Appolito, who is a world-renowned
for his pioneering work on MTM-based loudspeaker configurations.
Also available in sheilded form for Home theater application.
NOTE: The polyester/Fiberflex should be distributed evenly true enclosure,
with following proportions (loose fill):
12" x 60" in the front portion (270g/9.5oz).
12" x 36" in the back portion (150g/5oz).
Use less Polyester/Fiberflex if you want more bass.
