Isolating speakers from hardwood floors


I know this topic has been addressed in this forum already, but I have a more specific problem. I live on the 5th floor of a late 19th century apartment building with uneven hardwood floors. The floors transfer a lot of sound to the apartment below, which really bothers my new downstairs neighbor.

I have Tannoy Revolution R2 speakers on the spikes that came with them, but I have heard that spikes can make this problem worse. The spikes that came with them aren't great, so I am very willing to buy some other isolation device (BTW, has anyone tried Sound Quest Isol-Pads?). Naturally, I don't want to compromise on sound quality, but I don't want to upset my neighbor, either. I'm hoping that I can achieve both goals, and I would appreciate any suggestions. Thanks for your help!

"search engine" the forums for posts on Vibrapods: there have been several of them & some very recently. This might be very helpful for the scenario & they are quite inexpensive.
If cones are still desired try the BBC MK-2's; they have integral threaded locking levelers.
Sounds to me like the best thing you can possibly do is put Aurios Pros under the spikes. They give you almost all of the advantages of spiking, but float the speakers so there is some substantial limit on the floor-speaker interaction. They're expensive ($200 apiece, and you'll need eight), but worth it. You can check the website (Media Access or Vistek) or audionut.com. Good luck.
Use their regular supplied spikes placed on MDF 3/4" platform from nearest Home Depot. Place that platform either on the vibrapods that match excellent with hardwood floors or the bicycle tube.
If you want to go with the bicycle tube you'll need to get large staples to shape the tube for the platform contour and than just use a regular bicycle pump.
