thanks a lot for publishing these plans. This will keep me busy for a few days...
Greetings from Sydney
I just posted about full range drivers and some art stuff Im doing atm. Of course the art is secondary but creating a solid seque between form and function, I was just reading responses to the Voight pipe topic and realise the stylized tusk may be applicable. Im in no way constrained to wood and planar design.
My question is, because the internal volumes of what I do can be different to the outside appearance, and there is mention of parabolic relationships in the horn, do you think its possible to adapt eg design by @planet10 to an organically shaped output?
I would also ask if there is anything that could be improved, can a floor firing aperture be incorporated...
Thanks for any help
EDIT: Also, if the vertical cross section is no longer rectangular, then rear path summing with the direct radiating output of the driver is going to be reduced ie reduce nulls because there are no planar facings? Or as I have found with the sphericals I mentioned, they use tapered fusiform and the effect ie reductions is very noticeable in AB to normal golden ration box designs

Your original design is basically fine as is with bottom vent, just may need to shift the driver location, so figure at what floor height you want it and adjust taper to suit; no need to fold it unless wanting a horn tuned to a low Fs.
Re edit: ?? so will just say that yes, there will be some comb filtering between the driver's, vent's outputs that can be critically damped at the expense of reduced vent output.

Once you have the pipe geometry you can fold and bend (within limitations), and what you decorate it with on the outide just has to fit ther inside.
Lots if cheap drbivers: CHN//CHP-50, If your art installation needs more bottom, add separate woofers.

Re EDIT:
This is only concept massing atm. The speaker mount facing is show sectioned here...so Im saying normally the back plane of the enclosure would be planar/reflective whereas in this case there are no planar surfaces so there should be no chance of retransmission through driver cone or freq nodes/nulls?
I was thinking of maop 11
So you are saying if I want eg 30hz I should use a sub or fold?

Hehe...no its not an installation...just making the enclosures as art 🙂
AURASPHERE..."The Art Of Sound"...that kind of thing.
I do hybrid QRD/Helmholz studio acoustics...although this was at a friends cafe...but a deaf lady with a cochlea implant could actually hear properly on a saturday morning breakfast whereas she couldnt before. This is tuned to 600hz but because of the surface scattering and some other stuff means you can sit almost on top of it without resonance
Acoustics of listening space is of course part of the speaker system
