Has anyone had experiences good or bad with speaker isolation or isolation in general ?


hi
i have been enjoying buying and listening to hifi for some 35 years now and have seen many items come and go.I have also been interested in the audio cable discussions and i agree that cables do make a difference how much of a difference is a very individual, and a system dependent situation. There has been nothing that has got me so excited and improved the sound of my system that has ever made me want to really share it with fellow audiophiles until i started to try various isolation products.With so much choice from affordable to very expensive i found the hole subject very confusing and i did not know where to start. After trying lots of various products all shapes and sizes with very different results i decided to read reviews which is something i do not usually do to get some advise.I read a review on the Townshend audio seismic podiums they are isolation platforms that go under your speakers .This company is very famous for isolation ideas and have been around some 50 years based here in the UK they also had a factory in the USA back in the 1980s. I contacted Nick at Emporium hifi  and he agreed to install a pair for me so i could have a listen. My speakers are sound-lab dynastats which i use in quite a small room but with the adjustments give a nice sound. After installing the podiums we both sat down with jaws hitting the floor these podium things completely transformed the sound of my system to absolute perfection. After all this time trying various products under my equipment i have now isolated my speakers and the sound quality is exactly what i believe we all are chasing, my sound-labs are now transparent no more bass problems i have just got one big 3D sound stage the dynastats are now very open with deeper much better bass everything is perfect. I now believe isolating your loudspeakers is the first port of call i was so impressed by the Townshend audio seismic products i now sell them as i have never come across anything that has given my system such a great upgrade , the sound is the same as before but now its just so much better its playing deeper bass but tighter much more resolution and no boom , the midrange is so much more human sounding realistic and spacious with the top end so refined and perfect , is anyone using podiums and had the same experiences i would love to hear from you thank you john

hi toddverrone
your completely in the right direction with springs this is purely based on my own experiences.
if it helps Max townshend told me that you want the spring quite squashed so it is doing its job , thats why its so important to get the weight right, 
the hole idea is your equipment is actually floating so it is protected from the seismic vibrations down to 3hz,
i believe im accurate in saying no system reaches this sub bass seismic 3 hz level which means max townshends design is ideal for system isolation,
i got best results from isolating my speakers first 
if you are interested in the podiums for all speaker weights and sizes emporium hifi in the uk sells the products at some 30/40% discount so instead of gambling your money on DIY ideas which in fact could do the job there is an opportunity to buy the correct engineered product at more realistic pricing  that will do the job and look very nice too , im too only trying to help other audiophiles experience the magic of the podiums regards john
This is very interesting, because at louder volumes my new subs will cause oscillation that's from either mechanical and/or aerial feedback. It's been in the back of my mind, because I don't get it at the volume levels that I play music, but still...
I'm getting upgraded feet for my table, that use an internal spring system, so the results may be promising, as I attempt to eliminate this oscillation.

hi kenny
before you spend any money try out the townsend audio seismic isolation platform, all you need to know is the weight of your piece of equipment , then the platform can be supplied with the correct load cells , the isolation provided is down to 3hz you will get no better for the money if you check my previous link you will see where you can purchase at high discounted prices , 
if you start with your loudspeakers first you will hear first hand what isolation will do when done properly, the seismic podiums are ground breaking products , after all its your loudspeakers that cause nearly all the vibrations when playing music especially if they are spiked to your floor ,
please check out max townshend youtube video showing the positive effects of the seismic podiums and demonstrating the negative effects of  vibrations from using spikes even on concrete
my honest opinion is until you can completely isolate your speakers , your system can nether sound as good as it is , you are basically throwing your money away by keeping on buying better electronics.
isolation has provided the biggest sound improvements to my system , the biggest effect was from isolating my speakers , it was huge mind blowing i just could not believe the difference in sound quality . you can hear every instrument being played , the speakers become so transparent ,and musical  its something one has to experience for ones self ,
