passive radiating? (1 Viewer)

[Mikey L]

I just recently purchased a Boston Acoustics VR910 center channel and, upon close inspection, found that there was sound coming from the center and right side of the speaker, but little or none coming from the left....I questioned a salesman where I bought it and he said that was b/c it implemented a "passive radiating driver" and that the left hand driver was primarily used for pushing air and making the speaker more efficient...is he correct or do I have a defective speaker?

Just looked it up on their web site. The 910 does have 1 passive radiator. The next model up uses 2 active units.

Sure.
A passive radiator is used in place of a port....

The passive radiator is a form of tuning for the low end response. It is basically a speaker without the motor structure on the back and uses weight to change the tuning. Simply, it is just like ports used on other speakers.
Your speakers are just fine. Enjoy!
