speaker coupling question

I have the Nola Boxer speakers and have them on some good sand filled stands coupled to the top plate with blu-tac.  the stands at the bottom are spiked through carpet to a cement slab which is very uneven.  Its difficult to get these spikes completely even so my question is what would be an alternative to get better coupling?  thanks for any info.

+1 for 3 point feet/spikes. 

However, you want minimal contact surface, but as rigid a placement as you can.  That is, you don't want the speakers floating in the air.  You want them rigidly fixed in the 3 dimensional space. Any sort of solid 3 point footers that allow you to adjust the tilts will work, then add 20-40 lbs of weight to the speakers. :)

Cement slab being substantial speakers may sound even better as one with the floor, anchored somehow. Anchoring methods may not be as attractive though ;)

I was finally able to get the spikes even where the stands are solid to the cement slab, but wow it did take a while. I think whoever put that slab in had a hangover!


That's why spikes are adjustable, and yes a PITA to setup, once done don't move them.

Max Townshend posted a great video on You Tube displaying the effect of using his Seismic Pods under speakers. Well worth watching, even if you decide not to spend the considerable sum it takes to outfit a pair of speakers with them.

Cement floor is the best to spike into (couple) you should only de-couple on wooden or suspended floors. As you never want the wooden/suspended floor acting as a "sound board" for the speakers, which happens if you spike into them.

As for your problem getting level, BDP24 is right, it’s much easier with a three spiked stand, or unless you have adjustable spikes on yours???


Cheers George

I have a similar situation and I use hockey pucks to help level the speakers.

A three-legged stand.
