Grandmaster; Master - Cello Stradivari Series Owner's Manual

4
STRADIVARI SPEAKERS
PRODUCT CONCEPT & DESCRIPTION (cont.)
Since no single driver is required to overwork, a completely
effortless reproduction is evident on even the most demanding
musical passages. Two separate crossover boards are installed
with access at the rear of the speaker. Each crossover provides
signals to half the drivers (four mid, four high, and one low
frequency driver.). In this way, each board handles half the
power being utilized, thus providing superior performance.
Exclusive Cello design techniques, including tri-wired, dual
crossovers with paralleled drivers and Litz wire, enable the low
impedance characteristics of the Grand Master to be driven with
optimum results and very little loss of energy.
The Grand Master can be placed in even medium-sized rooms
(12x15') (3.65 x 4.60m) provided the ceiling height is adequate.
However, the forte of the Grand Master is filling large rooms
with clean, clear, natural sound without clipping, distortion, or
compression. It has an efficiency of 96 dB (1m @2.83 V). Yet
the "footprint" of the Grand Master is quite small so that little
room area is taken. They also project sound over furniture,
pianos, and other objects that might be in a room.
The Grand Master is designed to be driven by the Performance
Amplifier, in single or bridged configuration. Installation
requires four strong adults. The Grand Master can be placed on
bare floor or on carpet, using spikes or large bases for added
stability.
Because it is so revealing, the Grand Master is enhanced by
use with the Audio Palette or Palette Preamplifier to allow
compensation for tonal balance problems in the recordings
(see literature for AP, PP).
Strad Master
The Strad Master is essentially the same as the Grand Master,
utilizing four high and mid range drivers instead of eight, and
one crossover board. It is an ideal choice when ceiling height,
room size, or budget does not allow the choice of the Grand
Master. The Master can be driven by any Cello amplifier. Its
efficiency level is 90 dB. The Performance Amplifier or Duet
350 will enable the Master to achieve sound pressure levels of
115dB, and in bridged mode, over 120 dB. The Encore
Amplifier will provide extremely enjoyable results in many
applications as well. The height of the Master is perfect for the
normal living room.
