Raising a sub off the floor

[ryanosaur]

True. But I think the point was
co-location more than raising one off the floor.

I think I saw this as part of the Boss o Bass strategy with their stacked dealios... put a column in each corner... excite everything!

Including the nearest fault line!

Yeah baby, I'm thinking stacks of three in four positions in a typical room....should cover it

Don't forget one each as a seat!

Has this qualified for derailment yet?

I am not here to argue for this implementation.

Ya wait till the morning when @PENG will throw some Mathematical Subwoofer 4' off the Floor Shitt your way.

I guess the better question would be...what is the vertical dispersion pattern coming from a sub. If we understood that, it would answer my question. Right now, Im see snarky but funny remarks because we don't really know the answer.

Please don't shoot the messenger of this post, me!!! I've just read in another forum that raising the sub 25% of ceiling height improves bass SQ to reduce reflections off the ceilings. Is there any truth to this?

what exactly do you mean by this? elevating the sub or putting it on a platform?

For those in old science fiction, can I invoke the Tom Swift Repeletron Ray?

Go ahead and tell him. I know you're itching too.

Room modes occur in all three dimensions. The reason why you don't see people lifting their subs in the air is that it's impractical. And it's just not needed to get a smooth response.

Acousticfields promotes this heavily. I went through a number of their videos, in the end it's not about a sure improvement, but contextual; you might need it and benefit from it and you may not. You may even need the floor reflection.

Thing is acousticfields doesn't like REW and tries to do everything needed with acoustic treatement and placement avoiding EQ.

In the end it's just moving it on the third dimension. It may help and "help".

Isn’t bass non directional? Why would you need to build a massive riser to put it up higher ???
I can understand a small riser for shock absorbing
I got no clue were this idea came from

Not because of directivity, but reflections. It would still be nondirectional minus whatever floor reinforces.

This thread needs to be revived, with the introduction of new in/on wall subs. I am very interested in finding possible solutions to ceiling/floor axial nulls by placing subs at various vertical locations. I remember hearing Anthony Grimani talking about place subs at the location of a null to eliminate them. Any thoughts?
