rubber feet for B&W DM305 speakers?


I heard that adding rubber feet (from Home Depot) to these speakers will make them sound better. Any thoughts on this? What size feet? Also, how do think Polk RT15i speakers would work for rears with the DM305s and CC3 center?
Thanks

Shame on us all for pushing our individual preferences without seeking complete information.

Nobody asked Mr. Fishcall what kind of floor he has, which makes all the difference. Coupling speakers to a highly resonant suspended wood floor might cause far more problems than it solves, like boomy bass and transmitting tons of vibrational scum into his component rack. OTOH, de-coupling from a solid concrete floor might soften bass response and transients with little benefit.

We need more information before we can offer a properly useful answer.
