Description

The Acoustic Image Corus S4 is similar to the Coda, but has a different woofer for more forward sound that is more suitable for guitar than double bass. The Corus S4 has a 1×10 speaker configuration with a paper cone woofer and a 5 inch extended range driver with presence control in addition to the woofer. It is available with a one or two channel head which mounts directly into the cabinet. The amp head uses a class-D power amplifier with a switch mode power supply and a sophisticated, sensitive preamplifier. Every Acoustic Image design is engineered to accurately reproduce the sound of acoustic and electric instruments. Acoustic Image amps combine purity, power, and portability in a package that sets a new standard in high fidelity amplification. Upton Bass offers FREE DOMESTIC SHIPPING on the Corus.

The Acoustic Image Corus is available in a Corus S4plus Two Channel Combo (613 GA plus, $1419), Cabrio-Ready Corus EX  for use with a Clarus amp head (621 EX-C, $589), or as an extension cabinet (Corus EX S4, $569).
