Hiya, folks. I recently purchased two pair of JBL S26II's, an S-Center II and a PB10 sub. I'm considering setting the sub next to the TV stand, placing a very short stand on top of the sub, and the speaker on the stand. Is this okay? I believe the speaker is ~20lbs. If any vibration were an issue, I'd probably use a small blanket to place over the top of the sub, then the stand on that. Space in an issue with the setup, so this is why I'm asking. Thanks for any help.
