Chris, floating is right
It gives an exact idea, since it is a matter more terrestrial
as flying is over our heads, floating is subjected to gravity
It's also more predictable...are we talking about ufos ?? Something that floats in the air - if not a pure tone (sinus), everything (music) created by instruments has a start, a duration and an end . Like each note has an attack-sustain-decay in time

Mordaunt Short 552 took this approach. The drivers and baffle were attached to a fixed frame which formed the floor stand. The rest of the cabinet was then suspended on this, with rubber seals to ensure sealing. It must have been expensive to make and only lasted one version, as far as I know.

The Eclipse does something similar - at least, I believe the speaker is coupled directly to the stand.

Just change neoprene for the foam, make strong compression for adhesive faces
inside, put a performing driver and try to sell it for over 15000 $ ,if not over..

OK, so we don't really have a floating cabinet, simply one that is loosely attached via seals. Again, I'll leave the possible benefit of that in Chris' hands, he really is the smart one.

One question though: At what point do we recognize the value of the exercise going from a fairly loose cabinet which would have at least wave cancellation to a more rigidly attached one with little to no cancellation? I'm yet to see where this is beneficial.

That's the one Colin. Driver rigidly coupled to the floor, cabinet floating around it.

Cal, as well as possible sonic optimisation of the baffle, cabinet vibrations should not feed back directly to the speaker chassis. I'm thinking that the purpose of the cabinet is no longer structural, holding the drivers in position, but simply a device for containing and controlling a volume of air. Of course, moving the whole unit around would be difficult, which was probably one reason for the demise of the M-S, but we're DIYers; what do we care?

Cheers Steve

Pah! Frat boy bass.....As an ex swimming pool attendant, I will blow my whistle for bombing (cannonballing?), running, eating, petting and any music with Autotune. Currently staring at a tiny Karlson enclosure in foamboard. Then will return to this thread with a foamboard floating enclosure.

Cheers Steve

This floating/hanging them is quite popular now. I've been thinking about it myself too. The bass (up to ?Hz) must have a solid foundation for heavy coils and membranes pumping the air. But let's say above 3-400Hz I can't see any movement of membranes, and they could be very light Al or Mg cones 4" or like that (or electrostat). Then it makes sense to hang them! The force of the coil movement is small compared to mass (and mass can be added). A driver without a frame acts as a dipole and that has it's own consequencies - good and bad . Some people make a board with 2-3 drivers and hang them in air, not so good for resonances.
