Here are a few of the myriad products from the January 2000
Consumer Electronics Show in Las Vegas:
Square subwoofer technology increases output on KICKER Solo-Baric L7
subwoofers from Stillwater Designs, Stillwater, OK -- enough to give users the equivalent
performance of the next size larger speaker. This advance in performance is primarily due
to three factors, each of which results in an increase in the amount of air the subwoofer
can move: the square cone area (or Sd) for a given size baffle is 16 - 20% greater than
typical round cones; increasing the Xmax -- the distance the cone can move in one
direction -- gives the L7s 24 - 49% more Xmax than previous models; and gains in Vmax
(Vmax = Sd x Xmax) greatly increase the amount of air that the speaker can move. Since
square cones mount much closer together than round speakers, they allow better acoustic
coupling and a resultant greater output in multi-sub installations. Circle 400
The auto electronics section showed many advanced audio, navigation
and DVD systems, and two companies were promoting subscription-serviced, digital
satellite-broadcast radio. XM Satellite Radio, Inc., Washington, DC, and Sirius Satellite
Radio, New York City, NY, will offer 50 channels of commercial-free music and up to 50
channels of news in coast-to-coast coverage with no static or other interference.
Individual formats will be identified on the receiver's display, and many manufacturers
are lining up to produce OEM and aftermarket systems, and adapters for existing receivers.
XM will employ two satellites in geostationary orbit, while three Sirius satellites will
be in inclined elliptical orbits. Both companies will broadcast S-band signals in the 2.3
GHz range, and will use terrestrial repeaters in urban and mountainous areas to augment
the satellite signal and ensure unobstructed coast-to-coast reception for US motorists.
Home and portable radios will also be produced to receive these programs.

A battle looms between Sony and Panasonic over ultra-compact,
removable media designed to capture, save and share digital pictures, music and
information. Sony, Park Ridge, NJ, was showing the Memory Stick Walkman, Digital Music
Players, Digital 8 Handycam Camcorders and three VAIO personal computers with slots for
the Memory Stick, a 64 MB device that measures approximately 21.5 x 50 x 2.8mm and weighs
about 4g. A different style is used by Panasonic, Redwood City, CA, which teamed with
SanDisk to create their 64 MB Secure Digital (SD) Memory Card, which measures 24 x 32 x
2.1mm. Prototype devices displayed to use the Card included a calculator-sized music
viewer-player, a watch-type music player and a pendant-style still camera. Circle 403 -
