Equipment Rack

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.

Where does the vibrational energy from the speaker itself go?

In my system it stays in the speakers. At least for the bass range. Before the podiums (Magico spikes to floor) i felt the bass through my floor (wood on concrete) after the podiums i do not feel anything through the floor only through the air. You kind of miss the floor based boom at first but its really a fake effect, good for sound effects but not something i experience at live acoustic concerts

others with more knowldge of springs (Geoff?) may comment on whether the setup transmits higher frequencies, it may

recognize all of this is with a very inert cabinet design, and no ports on my Magico Q3s.

Ps agear. Nice room, mine is a similar size and likewise complex design albeit a more traditional Art Noxon design for sound isolation and bass response, despite the small size it works well and behaves as yours seems to really disappearing into the recorded acoustic

I love Massif Audio Design racks. I think they make very exotic and high quality wooden racks. :)

The springs are simply part of the mass/spring iso system. Analogous to seismic vibration isolation, isolating the system from the vibrational energy of the speakers (cabinets) is accomplished by absorbing the energy via the mass/spring system, where it’s converted to work and heat. The mass/spring system would thus have to move somewhat during the whole isolation process.
