Can we see the Nautaloss? Those do sound very natural with no box coloration. Being snowed in is a good excuse to build speakers. I am working on the bookshelf point source horn.

Hi X, sure, my fruit of the stoorm...sorry I did not take internals, but its basically like yours, except not as pretty. Sounds good though.
I think the idea of eliminating the back wave is better than bouncing it around in hypercube. I am for open baffles anyway...

Interesting 3 drivers on a hypercube with a tweeter on top! The rectangular boxes are the Nataloss's?

X, I know that thread very well. Great work there, you, Bushmeister and others.

Yes, those boxes are nautaloss. I started by making the box with the last side open, then inserted the snail in, closed the side and placed one more foam on the front with speaker, so i doubled the front. I am just learning to work with it.

When it comes to hypercube, b&o is no longer only one with three mids I could easily squeeze four mids there, to make it 4 ohm, they are 16 ohm each, but I prefered 6 ohm, hence three in parallel.
These 3" aura are leftovers from my line array built.

You could add 3 mids to the other 3 sides and then drive them all independently with DSP and phase array beam steer them like B&O.

What amp are you using in that little wooden box?

That thought crossed my mind, I thing the box is too small for that. Maybe next project...

I am using lm1875 little chips. Love the sound, especially in transconductance config. I am making quite a few, as I will one day convert the main system(s) from 2x4 mini dsp to 2(4)x8, so I will need four stereo amps. But that is slow project.
