Short Vs. Tall Satellites

TOBY Corp makes two satellite speakers--a Short Satellite 12 inches tall,
and a Tall Satellite 49 inches tall.
How are they alike?
Both are two-way systems designed to be used with a sub woofer.
Both use mica doped polypropylene woofer cones with rubber edges.
Both use sealed cabinets tuned for THX low pass theater setting.
Both have complex crossover networks. They are installed in free space, not
in the woofer cavity. Why? The thin plastic walls of terminal cups can
resonate when mounted inside the cabinet. Additionally, crossover components
generate heat, which is dissipated better in open air.
How are they different?
Obviously, the Tall Sat is floor-standing. The Short Sat needs a stand, or
may sit on a desk or bookshelf.
The Short Sat uses an exotic VIFA XT tweeter that is seen in systems costing
up to $35,000 a pair. The Tall Sat uses a standard VIFA TC one inch cloth
dome.
The Tall Sat uses two 5 1/4 inch woofers. The Short Sat uses one 6 1/2 inch
woofer.
The low range of the Tall Sat woofers is limited acoustically, rolling off
at 80 Hz at 12 dB/8ve. The low range of the Short Sat is limited both
acoustically and electrically. It rolls off at 18 dB 8/ve at 80 Hz, the
standard THX high pass frequency.
The crossover networks are different, since the drivers and the enclosures
are different.
Features:
On the Short Sat both the tweeter and the woofer have pure copper shorting rings in the
magnetic circuits to reduce harmonic distortion. The enclosure has a slanted
back to break up internal reflections. [A monitor version is available with
an extended tweeter mast and no grille.]
The Tall Sat uses two small woofers in two identical sealed enclosures. They
are a good fit for the tall narrow cabinet. The pair of woofers aligned
vertically creates a line source, good for projecting sound. |
