Boy, Oh Boy! Towshend!

@rixthetrick
Thanks. Good idea. I also emailed my contact at Focal and asked for his thoughts.
As a curiousity, I downloaded the Hamm Seismograph app from Google Play. Figured I'd try what they did at Townshend. One think about those videos, I'm worried that if someone accidentally bumped hard into my speakers, they'd tip over!

Is turning a subs volume all the way to 0 the same as turning the sub off? Or by leaving the sub on even with no volume, its crossovers get in the way of the floor stading speakers crossovers? Or maybe the crossovers are set in stone in my Classe processor....

In any case, just goofing around. I'll do some more legwork. I appreciate your feedback.

I'd be very surprised if Focal had used Townshend products, and be even more surprised if in Europe where they make and sell a lot of Focals, that someone hadn't purchased the exact model of your speakers and used Townshend under them.

I would email Townshend Audio and ask them if they have any feedback from customers who use your speakers.

Depending on your subs, disconnecting the RCA connections, or power will suffice. It's just to stop them vibrating the room and undoing all the good isolation Townshend will provide. Then put the subs on isolation if it works.

Speaker bars where you already bolt the feet under your Focals, that's what I'd do first. No modifications to the speakers, and stability for safety of the speakers, should be a great way to start off.

vinylshadow, There will be no stability problems with Townshend. The best by far but also most expensive will be to put the turntables on Townshend Platforms or Podiums. Either one will be a superb base for a turntable. But you will probably be able to get almost as great performance for a lot less money from 4 Pods. 

The way the Pods work the top part is threaded into a plate on the top of the spring. The plate is very secure and so anything treaded into it will move and be isolated but will also be stable. It will move freely but not fall over. This will be the killer performance value way to go. Podiums or Platforms will be even better but maybe not quite as good a bargain. Unless of course you value the looks of one over the other, looks do count for something you know.

The stone bargain in cheap is Nobsound. These should also be stable enough but there is a simple solution in case you are still worried. Simply take some nice looking wood, acrylic or Corian and make your own bases for the springs. The springs fit perfectly into 1/4" holes. Do a test to see how many springs you will need, then cut your pieces to 3" or so diameter to be however stable you want, drill em and put together. 

I have done this to make extra ones from my leftover springs. Works great. These are not as good as Townshend. Not even close. But incredibly good for the money, so good there is nothing to recommend above Nobsound until you make the big jump in both price and performance to Townshend.

The main drawback to Nobsound is the lack of damping. Townshend has this dialed in. So with Nobsound a lot more depends on how willing and good you are at tweaking, experimenting, trial and error. Townshend are set and forget, once level you are done.

That's great, glad to hear it!   I sure look forward to coming home and listening.  Cheers!
