1038AC

The 1038AC is a dedicated center channel version of the 1038A main monitor loudspeaker.

It is designed to be used with a pair of 1038A's in three channel (left-center-right) or surround sound applications where space near the video monitor or screen is limited.

•130 mm (5") high sensitivity direct radiating cone driver loaded with a Directivity Control •Waveguide™ (DCW™)
•25 mm (1") metal dome tweeter with a Directivity Control Waveguide™ (DCW™)
•All drivers magnetically shielded
•110 litre vented cabinet
•Tri-amplified: 2 x 200W, 120W, 120W
•Amplifier unit in a separate rack mount chassis
•Electronic crossover and protection circuitry
•Built-in bass, mid and treble level controls, bass roll-off and tilt controls
