General information and specifications:
Back panel:
The rear panel of the Phoenix serves as the heat sink for it’s three class AB amplifiers.
The panel is ¼ in thick. It is quite normal for the panel to run quite warm, and should not
be a cause for concern. It would not be wise to position the speaker in a way that impairs
air-flow around the speaker.
Electronics:
Your Phoenix is composed of very high precision parts. We hand select key capacitors
and use .1% tolerance resistors in key positions. All of this leads to speakers that match
each other with excellent accuracy. The Op Amps represent current state of the art. The
power amplifiers are capable of over 20 amperes peak current. The designer of these
circuits has over 20 years experience designing powered loudspeakers.
The scan speak tweeter used in the Phoenix is a favorite in the audiophile community. It
employs a double magnet, and is sweet and airy even at high output.
The woofers were chosen for many reasons, but their outstanding characteristic is a flat
frequency response and an extended response.
Cabinet:
The cabinet it beautifully built and braced. In order to suppress resonance, special
damping materials are applied to the sides of the cabinet. The front baffle is 1.5” thick
and the woofers are mechanically isolated from it. The ports are designed for high air
velocity without turbulence.
In short we are very proud of the Phoenix and we trust that it will bring you many years
of listening pleasure. Enjoy!
