Best way to isolate 120kg speakers?

[Guest jakeyb77]

Asking for some suggestions to isolate 120kg speakers on timber floorboards. 
Has anyone found a decent solution? 

[Telecine]

Coupling is generally a better solution than isolating. The traditional coupling solution is to use spikes.

How bigs the space under the floorboards Jakey?

Don’t I want to de-couple?

I'm in the isolate camp, the coupling camp is a bit too intimate for me

 

Maybe try some thick Bamboo boards with the spiked speakers on those, with the White's anti-vibration blocks under the thick Bamboo boards.

 

Yes, this is what I usually recommend, as it works well every time I implement it regardless of whether the floors are wood or concrete.

No you dill. I was wondering what the floor is sitting on construction wise,bearers& joists if it's a timber floor and what kind of airspace you have under the bearers. Does the floor bounce as you walk over it or is it rigid. Is it a polished timber floor or a carpeted underlay floor the speakers are going to be resting on or the horror of a tiled floor laid on a timber floor.

Oh I see. About a foot underneath the floor board. Just polished timber. Little bit of give. I just get a boom and this also invades the walls a bit. The SVS sub is isolated and made a great improvement

What about those isoacoustics Gaia things or the svs subwoofer footers - not sure if they come graded for such weight tho? 

 

Grizzly might be able to make something for you ?

@Marc was talking about them the other day at @evil c’s place 
I couldn’t seem to see any that would take that weight, unless I was to use a lot of them. 
I’ll look deeper into it

Yep. Titans. I’ve just ordered mine for the 140kgs each music machines arriving December 23rd.

Who’s the best to order through @Marc? 

[Guest]

I noticed Selby has 20% off on Isoacoustics atm.

 

They’d probably need to order Titans in though.

Which they are so win-win

No, you want to couple. Speaker manufacturers sell their speakers with spikes, not de-coupling devices.

Have you ever tried decoupling/isolating?

Couple of acrow props and you'll be right. I did this when I used to rent

 

The house wasn't built in underneath so I had free range. Fixed my turntable right up

Big $$ for the Iso acoustics, gotta be dedicated but ultimately a very effective product from what I've heard!

While you're buying your mighty Titans, grab a couple of sets of Gaia 1's for your ol mate evil !,(birthday soon)

I've got Gaia's under my Spatials which are not in the same weight division as your JBL's, but they were a marked improvement over the rubber feet the speakers came with, and the Herbies sliders I had in between. I'm on a floating floor over a slab and still worth it. I'd suspect the Gaia's on a timber floor would be even more impressive.

 

Perhaps it might be worth trying some of the cheap Bunnings vibration pads first though, just o see if it improves things

Mine too! I’ll buy yours and you buy mine

[Chill3]

Herbies have a range of option for not much money. In my experience its better to decouple on a suspended wood floor and better to use spikes on a concrete slab

I've experienced this A/B demo so many times now, in various locations, various systems, with different presenters (including our own show). It's just an absolute no-brainer.
