I'm curious about the possibility of a single mono point source with no resonance or phase issues. My idea is to find a nice full-range driver and simply rig it with cables from a frame/ceiling. No cabinet. Imagine it like a gong.
Is this a stupid idea? Are such drivers designed to be inside a cabinet only? Will I end up with a wimpy sound and/or a speaker swinging back and forth on a wire? Hehe. My only guess is that without it being bound to a solid cabinet/frame, the lows will lost to the air.

yes, I think you'll get not much below the upper midrange on up, and most FR candidates have limited excursion to start with, so not likely much SPL at any reasonable listening distance either.
You might consider a small baffle to mount the driver on and hang it from there. If you can add a subwoofer somewhere you could have an interesting system.
Try to calc around a little with the moving mass of the cone and the drivers weight. I would be afraid the basket would move back and forth.
PA - I'd imagine such a hypothetical system could be strung with sufficient carefully tensioned guy-wires to avoid that particular issue - but of course without an even minimal open baffle, very limited bandwidth and SP levels should be anticipated
"Thinking Outside of the Box".. I love it!
Maybe some damping material behind the driver to absorb the rear waves might help..
Add weight to the driver to overcome the forces of the cone!

Hi,
Its a bad idea unless the driver is huge, and then it
by definition will be a very poor full range speaker.
A small baffle won't help the physics much at all.
Neither will local rear resistive damping.

Hi Bugeats,
I did a google image search for "no baffle speaker" and got some interesting hits. I seem to remember a lowther design along the lines you describe being said to be successful but as you can gather by the general mood of the replies here it would be a bit of a challenge.

bare mounted loudspeakers
Hi there: Curiously the recommended method of testing parameters for loudspeakers is to accomplish the testing with the driver suspended bare. As with almost all audio concepts, their is prior art for using bare mounted drivers, I recall an interesting 4 way design posted herein called something like "Blackmore", but I can't find it through search. I am running a pair of TB W5-1611S-neo drivers bare, with a mounting plate the diameter of the driver in a FAST with a 4-8" drivers in a bass unit pentagon mounted H frame, biamped witha 175hz xover. So do not hesitate to experiment. ...regards, Michael

As you can see I'm new here. Heh, sorry for the late follow up to all these responses. It sent me down a hell of a path and back. I've been absorbing knowledge for the last 48 hours. I have a feeling I'm going to be around here for a while. It looks like there are other ways to accomplish my ideal of a highly focussed and accurate mono point source. At the moment I'm looking at "metronome" style quadratic wave guide enclosures.
Damn I really don't need another hobby, but the design constraints on this stuff has me captivated. Anyone want to do a commissioned build/consultation?

Take two drivers and bolt them face to face wired into a push pull configuration. You then have a true onmi speaker with some interesting results.
