B &W bolt thread size?

Thanks for the response Do the spikes mar the speaker bottoms? I called B & W the other day with no response.

Thanks for the response. The CDM 1NT's have four screw holes in the bottom, the rest is finished wood. I also have the rubber feet screwed into those holes. When you remove the rubber feet those holes line up exactly with the holes in the speaker stands. I want to utilize them for securing the stands. In doing so I will have the speaker sitting flat on the stand, I understand that this is not optimal for sound. If I place some sort of spike I will ruin the wood, that is not an option. Any remedies, or just forget about the spikes?

My new stands are in fact brand new B&W's, but they are not the stands that were originally offered with the speakers. I filled them with sand, sat them on their rubber feet and their sound was nicely enhanced. Now that they are secured directly to the stand they seem to be somewhat muted. Security over sound? Not a good trade off. I need to figure this out...
Thanks again for your interest in helping me out.

My response from B&W is that they should sound better??? And, I should check for a blown tweeter. No blown tweeter on both sides. Anyway, your suggestion is the direction I will pursue. I searched last night for isolator's etc. I'll keep you posted.
Thanks again.
