Series 4plus Clarus head, Coda, Corus and Ten2 combo; and Coda
EX, Corus EX and Ten2 EX extension cabinet.
The Basics
Our Series 4plus product line consists of a two channel amp head and
three speaker cabinets. The head mounts in the cabinets using our
exclusive Cabrio Docking System to form three different combo amps.
The Clarus amp head uses a class-D power amplifier with a switch
mode power supply and a sophisticated, sensitive two channel
preamplifier. The speaker cabinets have a 1x10 or 2x10 speaker
configuration. The features of the speaker configuration define the
specific combo model. The Coda combo has a 1x10 speaker
configuration with a poly cone woofer. The Corus combo has a 1x10
speaker configuration with a paper cone woofer. Both have a 5 inch
extended range driver with presence control in addition to the woofer.
The Ten2 combo uses a 2x10 speaker configuration (one downfiring,
one front firing) with poly cone woofers in conjunction with a 2.5 inch
tweeter. Each cabinet type is also available as an extension speaker
in either a “Cabrio-ready” configuration or as a fixed extension cabinet
(Coda EX, Corus EX or Ten2 EX).
The features of the S4plus Clarus amp head are:
-Extended frequency range, high fidelity sound
