Description
Monitor Audio SB-4 Passive Soundbar
Large passive three-channel Monitor Audio soundbar intended for 70-inch and larger televisions in cleaner home theatre installations.
SB-4 is the largest model in the range and is proportioned for big screens where a shorter soundbar would look undersized. Like the smaller models, it is a passive left/centre/right speaker and requires an AV receiver or suitable amplification.
Installation and System Planning
Use it when separate front speakers would create too much visual clutter but you still want a conventional surround system behind the television. A subwoofer and correctly positioned surrounds complete the system more effectively than asking the soundbar to handle every channel and the deepest bass.

The Audio Experts Take
The SB-4 is intended for very large televisions where a smaller soundbar would look undersized and provide less front-stage scale. Because it is passive, treat it as the left, centre and right speakers of a home theatre rather than as a self-contained TV speaker. Pair it with the right AV receiver and subwoofer, and talk to The Audio Experts if you want help with the complete layout.
