:eyebrows:
Is there such a thing as 'a spare few minutes' on a Satuday morning?
Well, I have too much time on my hands you would say...
As a compulsive tweaker, you guys have probably followed my recent posts about my new Tannoy LGM 12.
Let me fist reassure you, we are still well into our 'honeymoon' period. It's love everywhere... I am not proposing to replace them by their 20 years younger eastern european conterparts.:eyebrows:
But recently I have had the faint feeling tha somethin wasn't exactly as it should be. Living in purpose build block, my floor is wood. Not the old Victorian stuff, just some pretty cheap modern stuff.
Some of the lower register was being transmitted to the floor boards. Bad news in my book. For me, and the neighbours!
So after a while :scratch: I came accross this video...

Very instructive viewing, isn' it?
So off I go in the search of some compression springs... Relatively easy with eBay and a few ideas on how they work.
A few days later, here we go:

Simple 2mm thick wire, 5 coils with a outside diameter of 21mm. 12.99 GBP on eBay. It should take the load easily (nearly 20kgs per speaker), without throwing it into stratosphere.:eyebrows:

Now starts the game of patience, the 'spare few minutes on a Saturday morning' as per my introduction to this post.
The difficulty here is to evenly balance the speakers on those 4 springs. it's all about weight distribution. So you kind of have to imagine where is the heaviest point of the speaker and try to position it dead center to the rectangle formed by the 4 x springs. If you have a bad back, please ask for some help. You will have to move the spaker millimeters buy millimeters, so be aware of their weight!
In the end an even distribution will give you a nice bounce on your spakers. Visually th 'pressure' on all springs should be equivalent. meaning, no spring is squashed more thant the others.

A bit like this.
So, now I can hear all of you shouting, why the hell is he doing all this! Is it going to work?
On goes this 'torture' test album for the bass performance of your system.

Before my very cheap 'seismic' isolation treatment, the first track would send my furniture buzzing like it was possessed by a swarm of honey bees, not nice!
Now, thanks to a little Spring, it feels a lot calmer here. And guess what?
The bass performance is so much better, tidier and leaner, yet bitting like a staffordshire terrier...
the upper register have benefited from this tweak too. More details is perceptible in the mix. And it seems that the sounstage hs gained a few inches in height, something I had not envisaged possible before.
DISCLAIMER!!!:stalks::stalks::stalks:
So, feel free to follow my modest take on Townshend path, of seismic isolation. But, please, again be very careful when balancing those speakers of yours, make sure help is at hand, take your time and do it slowly. Don't come and blame me if your precious coils come crashing on your feet and hands, smashing your precious collection of Ming vases, etc.... Make sure no kids or pets are messing around either... The whole tweak once achieved is WOOBLY, meaning fragile and potentialy unstable. Also, I am using bookshelf spakers here. I am not sure how that would work with floorstanders. Here you are a bit on your own. I won't be held rsponsible!:stalks::stalks::stalks:
Well, I hope you will find this post beneficial, if not instructive.
Happy tweakin!
