Q. What can help reduce noise transmission to my neighbours?
Answer:
We normally supply spikes with our floor-mounting loudspeakers, including subwoofers. We also provide rubber caps for the spikes to avoid damage to wooden floors.
Spikes would maximise the sound transmission, but using the rubber feet should be an improvement.
The very best would be to mount the subwoofer on cubes of dense foam like neoprene.
