Isolation platforms for Cube Audio Jazzon speakers

Can you put some words around symposium to aid my search?  I can't sit the speakers flat on the floor as they radiate bass from the open bottom of the speakers. 

Chayro,

Thanks for the reply.  The Cubes have fixed rubber dome pads on the rear and come with spikes to raise the front of the speakers to provide a proper opening for bass response on the bottom of the speakers.  I don't fancy the appearance of the tilt to the speakers so i am using the rubber/foams sandwich pads under them at the moment.  The Symposium devices are nearly as costly as the Townshend gear.

Soix,

I am gonna give the Nobsound springs a whirl. I have them under my sub and they are effective and affordable.  I reckon that I will ultimately try the Townshend Siesmic Bars at the cost of about $1K.  They would solve two problem:  they have about .75" of elevation from my carpet to allow the bass response and they are stellar for taming speaker vibrations. But, I will try the springs first.  Thank you for the suggestion. 

David,

I put this same question to Cube Audio a while back and got this response:

"Hello Mark,

The simplest way is to make a platform with a slightly larger cabinet outline at a local carpenter, with acoustic polymers placed underneath. It may be a rubber element that dampens vibrations very well. 

We have often seen such solutions in rooms with long pile carpets.

I hope that this solution will be helpful."

Best regards

David Ten infers the efficacy of maintaining the "tilt" angle with the small rubber domes in the rear of the speakers and the spikes in the front to perhaps to give the bottom-firing bass response to be optimal.  I personally dislike speakers with a tilt and at the moment have the speakers level with rubber/foam blocks from McCarr Masters under the corners resting on slightly oversized 1/2" MDF pieces of wood on my carpet.  Not addressed in the response I got from Cube Audio is the issue of whether the opening on the bottom of the Cube speakers is optimized with the factory "tilt" similar to sizing a bass port on the back of speakers, which is not trivial a matter.  

I started with the factory tilt on my thick wool carpet and it clearly muffled the LF response.  Leveled up on the wood platforms with rubber/foam blocks on the corners yielded a massive improvement in the LF as might be expected.

Any thoughts, David?  

David,

A very reasonable and erudite response, pointing out alternatives.  You and Charlesdad are always helpful with your responses.  Thanks very much... I will experiment.  

I had my Dynaudio C1 Signatures playing for a week and loved the directness and detail of their performance, but I like the Jazzon's even more.  The Cubes just sound more like musicians playing in the room and not like speakers playing music in the room, to put it one way.  There is such an effortlessness and ease to the music with the Cubes and they love Don Sachs/Lynn Olson's new 300b monos.  

Gents,

I ordered the Townshend Seismic Sound Bars today for my speakers. They are less than half the price of the Seismic Platforms and might be nearly as efficacious.  I am sure that they will be a nice improvement.

My Italian friend with upgraded Nenuphars has recently purchased the new Qualio speakers and prefers them his Cubes. The Qualio's have gotten fab reviews in 6 Moons and elsewhere and are half the price of the Nenuphars.  I'd be keen to hear them sometime.  

Thanks Ozzy, these seem quite affordable and effective, but there is no way to attach them to the bottom of the Cubes, so the Townshend Platforms or Sound Bars are the best alternative.  

This comment from the company seems very dubious:  

Here is what Stack Audio replied to my question.

"The AUVA Loudspeaker Isolators have a burn in time to let the particles settle. We estimate around 6-7 hours although customers have noted continuous improvement up to the 20-hour mark in the past."

"Just a follow up note – I should also mention that several customers comment that no burn in time is required and there is an immediate impact. I think it varies on a case-to-case basis.

I ordered the Townshend Sound Bars which are expected to arrive in a few days times.  I remember when I put Iso-Acoustic GAIA footers under my Spatial Audio M4 Triode Masters whereupon the improvement in SQ was instantly apparent.  I am hopeful for the same improvement with the Townshend Sound Bars.   

I got them today and  am having a hard time trying to get my speakers levels with the adjustments with these Sound Bars under my Cube Audio Jazzon speakers.  Information from Townshend has not been helpful.  I sorta got them leveled and frankly don't hear any noticeable improvement in the SQ.  I used the sandwiched rubber pads under the Cubes prior and they might be more efficacious that I might have thought.  

Any tips on the setup would be most helpful as well as any comments on their performance would be very welcome.  In contrast, putting Iso-Acoustics GAIA footers under my Spatial Audio speakers yielded a fantastic improvement in SQ...  immediately.  I am not hearing anywhere close to the same improvement with the far more expensive Townshend Sound Bars.  

Heck of a deal, my Townshend rep called me just now and opined that the solution to the problem of my inability to level them can be solved by higher-capacity load cells in front Sound Bars.  He is getting them out to me without a concern of payment so I give props to him and the company for their excellent response.  I am really hopeful that this solves the leveling issue.
