I have very thick carpet over dense pad on a concrete slab floor. I currently have Zu’s on spikes through the carpet to the concrete. The speakers are rock solid to the floor with brass weights on the top front of the cabinets. I went to 15”x15”x4” walnut Timber Nation pedestals spiked to the floor with the Zu’s on that. This setup sounded terrible. Sean at Zu responded personally to me suggesting spacing and placement distance above the pedestal. I never came close to how it was before and went back to what I first mentioned. My previous system in the room was high power with JBL 4312’s on 26” Sound Anchor stands, again with spikes through the carpet and into the concrete. However the JBL’s had dots between the speakers and the stands. This combo weighed about 100 lbs per side and wouldn’t move even with someone bumping into them. What I’m not clear on that could be addressed by those above is running springs on carpet and not getting a speaker that’s like a rocking horse. Also the bottom line is we have to try it ourselves and hear the results. FWIT I’m in the opinion that a loose speaker rocks back and forth in response to the driver like Mr Vandersteen spikes his stuff. And those beautiful Timber Nation walnut pedestals made great amp stands. Regards , Mike B.
Speakers on carpet over concrete
My system is current located in a partially finished basement. The floor is thick carpet over a thick pad on top of concrete. Does it affect performance of the speaker differently if spikes are used that pierce the carpet and pad, contacting the concrete below versus removing the spikes and having their "feet" resting on top of the carpet which is also a bit less stable? I'm sure I'm not the only one with a system installed on carpet over concrete. How are yours set up?
