SUMMARY OF COMPONENTS
The Reactor FR Powered Cab and FR Powered Wedge are comprised of
a 50-watt RMS tube audio power amplifier section and a very high
efficiency tuned speaker system installed in a high quality speaker
cabinet.
The power amplifier employs one 12AX7 and two “JJ” Brand 6L6GC
vacuum tubes to deliver full-rated power over a full-frequency response,
with high headroom and very low distortion. In other words, this is an
amp “without an opinion” which amplifies without coloring the tone.
The speaker system consists of a 12” driver, a tweeter/horn, and a
crossover network. Its range is wide and smooth, without peaks or
notches. The high efficiency of the cabinet design, coupled with the
dynamic abilities of the amp and speaker, provides a level of performance
that one would expect from more powerful and expensive systems.
Through the use of the speaker jack and switch, the powered cab or
wedge may be used to drive an external speaker, or the internal speaker
may be used with an external amplifier. See the annotated Panel
Diagrams (p. 4-6) for more information.
The Passive Cab and Passive Wedge offer the same construction and
speaker/crossover systems as their powered counterparts, differing only
in that their power amplifiers have been removed and replaced with a
jack plate/control panel.
The MB-50 Mono Block Power Amplifier uses a power section similar
to that of the powered cab and powered wedge models but with an
active presence control replacing the passive tweeter level. It is housed
in a conveniently compact enclosure with no speakers and may be used
with our passive cab/wedge models or any appropriate speaker system.
