The Basics
6
Our Series 4plus product line consists of a two channel amp head and
7
three speaker cabinets. The head mounts in the cabinets using our
exclusive Cabrio Docking System to form three different combo amps.
7
The Clarus amp head uses a class-D power amplifier with a switch
7
mode power supply and a sophisticated, sensitive two channel
8
preamplifier. The speaker cabinets have a 1x10 or 2x10 speaker
8
configuration. The features of the speaker configuration define the
8
specific combo model. The Coda combo has a 1x10 speaker
configuration with a poly cone woofer. The Corus combo has a 1x10
9
speaker configuration with a paper cone woofer. Both have a 5 inch
9
extended range driver with presence control in addition to the woofer.
11
The Ten2 combo uses a 2x10 speaker configuration (one downfiring,
one front firing) with poly cone woofers in conjunction with a 2.5 inch
11
tweeter. Each cabinet type is also available as an extension speaker
12
in either a "Cabrio-ready" configuration or as a fixed extension cabinet
12
(Coda EX, Corus EX or Ten2 EX).
