Equipment Rack

If you still own the Monitor Audio PL500 these have an absolutely ginormous footprint (20"x25") -- bigger than the biggest stock podium so the quote may be for a custom job

Likely the Seismic Isolation corners may work best for you -- two sets of 4 in Size C should be around $3400

These will fit neatly under the existing spikes of your PL500

You could also explore the bars -- I'm a bit ensure on sizing (size 2?) but if you can find ones that fit these should bring the price under $3000. 

I recommend analogueseduction -- they were very easy to work with, and as these items are custom built ordering from the UK will be just as quick as ordering from the US (maybe faster if they do not trans-ship)

Hello Geoff,

Agreed that damping a chassis will have an effect on the sonic outcome however it will also change the sonic of the component and in most cases change the original musical character of the product from what the designer or name brand is presenting.

Speaking as a racking manufacturer and not a component designer, our products cannot fine tune, harmonically change or voice each component individually as we are dealing with an industry of various products, each one being unique in their sonic offering.

Our goal was to represent all the name brands of equipment performance exactly as the innovator wanted them heard. The original presentation of the loudspeaker or component without altering their sound character was the ultimate challenge. By establishing and/or improving upon the operational efficiency of the component definitely delivers more sound quality of the product without altering the original harmonics. That specific engineering goal took over fifteen years to develop with concerns to the cello and upright bass endpins. Obviously if we altered the sound of the instrument the musician would become extremely angry and zero sales along with a poor reputation would exist among the all important music makers.

We chose to use materials where the damping factors within the specific steels and brasses delivered the right dynamic as not to alter the original voice of the component or loudspeaker. This is where geometry becomes the all important factor in any design, as you are aware, too much material of any kind even that of a quality brass or steel with sink the live dynamic in a heartbeat. Once the life of the music is over-damped, it never comes back.

I am sure you are aware the majority of electronic and loudspeaker manufacturers spend little if no time on understanding the mechanical sciences or vibration management technologies where the both of us are heavy participants. The one key item we do have in common is not one of science and that is until people physically experience what we do, no matter how many positive reviews that state racking and vibration management are important as any loudspeaker or amplifier choice, rapid expansion and discovery in our sector of the industry will be a tough go.

Please don’t put words in my mouth. What I am saying is that damping a chassis or electronic element or whatever - when it is done correctly and without over-damping - improves the sound. I didn't say it would be easy, what is, right? I wish to hear better sound that what the original product sounds like, yes that’s true, now that you mention it. The whole idea is to try to obtain a better signal quality than you had before, no? Note to self: This is the same argument that Michael Green and I used to have all the time. Let the vibrations flow free. Just like old times. ;-)

Audiopoint,

Monitor Audio PL500 speakers. 

Try here for in-situ measurements, Townshend do the demo in place by jumping on the floor around the speakers

 I saw those too.  What about the vibrational energy from the speaker itself?  Where does that go with the Townsend paradigm.

They are expensive.  Wow.
