Time
Aligned™ Studio Monitor System
Features:
First Time
Aligned™ monitor system designed for the professional studio
Features
UREI 800 series TA™ network (patentpending)
6048G duplex
with UREI custom H.F. horn for extended and more uniform H.F. response
Second L.F.
15" direct radiating driver fed from 3-way TA network for extended L.F.
response and higher power handling capability at low frequencies
Graeter than
11,5 cu ft. Enclosure with pressure cotrol aperture for excellent L.F. damping,
good efficiency and low distortion.
Unique
enclosure damping method provides high efficiency conversion of low frequency
aound pressure to adiabatic enrgy.
The 813
Studio Monitor System is the first generation product of a joint R & D
effort of UREI and E. M. Long Associates. The Time Align™ Technique is a
realtime design method, utilizing proprietary instrumentation developed by Long
which allows the driver placements and network parameters to be adjusted
simultaneously, achieving near perfect alignment of the frequency components of
a complex transient waveform as heard by a listener.
The
importance of time (phase) parameters of loudspeaker systems, in addition to
smooth frequency response, has been postulated for many years. These group time
delay anomalies may be severe in some multi transducer systems, although they
may exhibit satisfactory or even excellent frequency response.
For stereo
applications the model 813 Studio Monitor System is built in
"mirror-image" (813 L, 813 R) to produce identical dispersion towards
the listening position between two systems. The series 800 TA networks with the
800H custom H.F. horn, are also available separately in two way and three way
configuration for both the 6048G and the 604E.
