I need to mount some speakers (pair each of M2s, M3s and QS8s) that have the single center mount point.

I have some Vantage Point BKSP speaker mounts I want to reuse, but they are designed for two screws in the back. The Single Post mount is optional.

What is recommended for mounting:

1. Go ahead and use what I have, just be careful with the two screws in the back of the speaker?

2. Contact Vantage Point to get the single-post mount option?

3. Throw out what I have and spend $80 per pair for the FMB mounts?

P.s is it really the case the the QS8s are sturdy enough to only be mounted using the single center mount?

Thanks,
Craig
