Squash Balls or Spikes...Maybe both!!??

Bill F, I live about 20m from a tidal river and I can't enjoy listening to my system from a black bag on the riverbed at high tide!

Next idea........

Not the boss, huh? Big mistake.

I use 3 spikes on my speaker stands, and then I use Harmonix spike bases similar to these (mine are black):

Position your speakers carefully, take your time.
Then put these under the spikes.
These have a kind of a rubber that after some time,with the speakers weight, will stick to the floor (although they can be removed quite easily).
They work very well, better than the spikes directly on my pavement.
Also an advantage is that you can cake your speakers out, but their position is marked, these bases will be sticked on the floor, you know exactly where to put your speakers back again.

My wife tells me when I am the boss!

I have been promising her hardwood flooring for about 2years so once we get it I had better look after it. There is NO WAY I am going to be the first to damage it! Not by accident or drilling through it!

Ill try the 3 spike arrangement on those puck things.

Here are my babies

Just two tips:

1.) Play around with placement until both criteria are met: It sounds good AND your wife is content. So there is at least some guarantee that they don't have to be moved anytime soon.

2.) Go and drill the holes one fine day when your wife is not at home .........

(sorry for my english)
Hi boys,
Well, mass for compilance = resonant frequency (Fr) ,ok?
two possibility :
a) Fr into audio-band . The system work on " elastic reaction" ( this is bad thing)
b) Fr below the audio-band . The system work on " inertial reaction"
( this is good thing)
If you use spikes you can obtain Fr max 3-4 Khz and minimum some hundred Hz , it depends.
Yes, spikes = springs , ok?
The goal is to obtain a subsonical Fr so the "forces exchange" is minimum and the relative immobilyty is preserved (= no vibes).
Spikes pseudo-theory is a storical error ( or a mistification?),
if you design a high-end speaker ( or any audio component) with
a"wonder" set of spikes you don't know basic laws of mechanics.
I hope my translate be decent ( i'm not sure..) and excuse me for too much technical simplifications, but the " subject " ( vibes) is too much difficult for me( in english . )
Experience: put 3 air spring under the speakers, then the source,
then the preamplifier........
In USA , look at the Newport air spring.
They are much expansive , but the concept is simply !
With a bit of fantasy .........
DO IT YOURSELF !

That's the right approach.

Any ideas on how to make a push bike innertube presentable?

[carlosfm]

I wouldn't use that under speakers...

Do those things still exist?
Most tires nowadays are tubeless.
