I currently have B&W N802 speakers resting on small felt pads directly on a wood floor which is cemented to the concrete pad underneath. I'm considering putting the B&W N802 spikes back on the speakers (they were used when I had carpeting in the room) and protect the wood floors with "tendercups" which are small metal devices that accept the spikes and protect the wood floor.
Is there any real advantage to using the spikes on a wood floor? Will spikes likely improve the resolution? Will spikes likely help or hurt the base response?
