SPL-td1 Loudspeaker from Sound Physics Labs
 March 26, 2000 Sound Physics Labs introduces the SPL-td1 loudspeaker, a single acoustic
source trapezoidal loudspeaker capable of operating in two-way or three-way active
or passive modes, truly acoustically arrayable.
This latest loudspeaker from Sound Physics Laboratory's sound engineer/designer
Thomas Danley combines the outputs from multiple drivers to drive a single horn,
while allowing each driver to operate in its own frequency range. This configuration
results in a seamless transition across the frequency range and is automatically
time/phase correct. With unusually low "side spill" and excellent pattern
control, the SPL-td1 delivers fully intelligible sound even in "poor"
acoustic environments and produces clear and articulate concert level music.
The cabinet houses two 12-inch low frequency drivers, four 5 1/4-inch compression
loaded mid frequency drivers and a one-inch high frequency horn in a Unity Summation
Aperture (Patent Pending). The SPL-td1 offers two-way or three-way active configuration
in addition to passive mode operation. While in passive mode operation, a high
frequency boost/cut control allows users to increase the high frequency sensitivity
to meet application requirements. Amplifier capacity in passive mode operates
at 800 watts RMS, 20Hz to 20kHz. Sensitivity at one-watt, one-meter is 103dB SPL
(one unit). The SPL-td1 boasts a frequency response of 80Hz - 20kHz +/- 2dB in
passive mode. Crossover points occur at 300Hz and 1200Hz.
The SPL-td1 weighs 130 lbs., is 29"H x 23"D x 19"W, and is constructed
of Baltic Birch on a 30-degree trapezoid angle. The back panel gives users the
option to use two x NL8 (Active) and two x NL4 (Passive) connectors. Fittings
include pole cup and four handles. ATM AMFS Series recessed track hardware makes
flying the boxes a snap. Standard finish is a black catalyzed texture coat. The
SPL-td1 can also be ordered in white or a variety of natural wood finishes.
