Isolation platforms for Cube Audio Jazzon 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. 

Ha.  Shocked you already have them!  I’d be very interested in your thoughts on how they work with your speakers.  Honestly, the cynical part of me thinks springs kinda work the same way (differing tensions notwithstanding) and that these should capture a good chunk of what the Seismics do.  Then again, the devil’s always in the details and Townshend may well have some secret sauce in there that takes them to another level entirely, albeit at a much dearer price.  Gotta love this hobby. 

@whitestix If you haven’t already done so, search the Nenuphar thread for posts related to your question. Others have tackled this.

I use Eden Sound Audio’s traditional brass spikes for the fronts and their hemispikes (with adhesive) for the rears of the Nenuphars.

What’s most important is to maintain the angle of the speaker cabinet.

Milimeters of change in cabinet height will "giveth or taketh away" due to TQWT enclosure and it’s bottom porting. Your room flooring, speaker positioning, and room are also ’actors’ in this play. : )

Hi David,

You’ve   owned the Nenuphars speakers for sometime now and are very familiar with their set up characteristics. No doubt your contribution here is very much appreciated and valued. It’s important to recognize the necessity of maintaining the appropriate speaker front tilt alignment.

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?
