Spikes

Yes . Adding spikes can dramatically clean up the midrange and smooth out the bass response. On some systems , spiking can increase transparency and soundstaging properties. The speaker will no longer be coupled to the floor .

Not really, however, you might find that the sound improves. You should be able to go to any high-end shop and buy some. If there are none near you, just hit up an online place.

They actually will, if designed properly, be coupled to the larger mass below..the floor.. Tom
