Vibrations eaters on top of the speakers

[mkrzych]

Hello,

Have you ever seen or use a specialized vibrations eaters/rings on top of the speakers to dump the enclosure resonances? If so which ones, where to find this kind of accessoriums?

Hi. You can try Artesania Audio dampers (MKIII version). You can check them in their web ( Artesania Audio. Design and hand-made production of furniture HI-FI ). You could contact them and I do not think they have any problem to ship them to you.

No conflicts of interest BTW

Regards

Do you know about pricing?

[oscarnr]

Around 180€ per MKIII damper. Not cheap.

I recently have bought 2 dampers improved for my electronics

The Totem Acoustic Beaks have been around for a very long time. $125/pair. I used a pair when I had Totem speakers.

Indeed, not cheap. Wondering if any improvement to the sound?

[wgscott]

As in marriage, I never get any credit for what I don't say.

[mkrzych]

Have read the Stereophile article about Totem and it seams that the improvement may be different or no at all. Like marriage ;-)

I can only comment with respect to the Beaks, and it was about 10 years ago, but I did not perceive any difference with the Beaks in place so I sold them. The Totem speakers were terrific though....

Not cheap at all. I haven't test mine yet, so I cannot speak. Effects will depend on how prior speakers isolation is and weight of them. You can try with a pair of big decoration books on top of speakers ;-)

 

Cheers

Just one thing... Don't most speaker manufacturers know their speakers will vibrate and take that into account when they design them?

[wkhanna]

As I understand & have seen in various speakers & the their design, cabinet resonances are addressed relative to the price point of the particular speaker. Resonance cancelling designs, bracing & effective dampening materials are typically used but all add cost. The amount to which all these means are used is usually relative to the cost.

Yes, but my point is that as well as trying to eliminate the vibrations, to a certain extent the manufacturers also work with the vibrations. Deadening a speaker not designed to be dead of vibrations may not improve its sound...

Yes, agree. But to the certain extent putting some absorbing heavy material atop of the speakers may eliminate some vibrations, even they are outside the audible range.

 

Those "dumpers" are pretty nice (also not cheap) BTW: EntreQ - www.entreq.com They have pictures where this kind of vibe eaters were put atop of Alexandria speakers, which as you know are rather top end.

Whats the difference between those entreq vibb eaters, and the White Doorstop With Cath Kidston Ikea Rosali He... - Folksy door stops from Ikea??

Adding a damper to the top panel will only help the top panel.....usually the smallest panel besides the bottom and as such, natively the least resonant. Consequently, surface damping will leave the damping unit to resonate at its own freq dependant on the material. If you suspect resonance, remove the midwoofer(s) and inspect the internal bracing. You can add if you like using hardwood dowels of 3/4" diameter or larger...horizontally from side to side would be most effective, bracing the largest side panels. Constructing expanding braces is pretty simple too where you can't fit the size needed. You'll need some machine thread inserts as well as a threaded stud and two nuts and washers. MUCH more effective than the devices you mentioned.....and much cheaper too!

mkrzych - if You don't afraid of audio voodoo You can check Albat Revolution Loudspeaker Chip (Vader is mine ;-) ):

We've got a pair on test, and .... probably is too early to describe any influence ;-)

I quite agree, Harbeth is a good example.

Once you have optimized the inside of a speaker, mass and stiffness are the remaining tools to combat cabinet resonance. There are inexpensive aftermarket solutions to increase these, but the drawback is that they are ugly unless a lot of labor is done, or you are creative with rock and/or concrete.

 

Glue slabs of something nonmagnetic, hard, and heavy to the outer surfaces of the speaker. Be sure those surfaces are either radiused where they meet the speaker edges, or have thick felt or another lossy material to diffuse the diffraction from sharp edges. In an ideal world we would locally buy heavy composite enclosures (basically concrete), bolt our drivers and crossovers to them, and spend a fraction of the cost of showroom speakers. The mass and smooth finish of full-range loudspeakers typically account for at least half of the cost of models up to around $20k/pr.
