😲 You've NEVER Seen Anything Like This - Fourier Transform Speaker at Axpona 2025

Music clips and my feedback are in this follow-up video...

Me, listening on my phone speakers “come on man, show us how good it sounds”

I do love this tinkerer aspect of the the audiophile industry. That one obsessed guy who wakes up with a new idea and goes all in. It would be hilarious to just tell him out of the blue "OK I'll take a pair". I bet he wouldn't know what to do.

The main problem is that the drivers are not co-located, so phases are still messy. The drivers location in space can be accounted for by DSP, but only for a single (fixed) listener position. It would be interesting to track the position of the (single) listener and change the phases accordingly and in real time. Alternatively, the drivers should be placed on a spherical surface centered on the listener

When it reaches 88 decibels, it will take you back in time.

I like this guy, and i like his spirit and energy. I get it also, you decompose a time domain signal into the frequency domain and bin it into 20 frequency divisions and then drive each speaker with a sine wave with that associated bins amplitude. You may need to run a sliding window at 44khz in order to get high fidelity output, in which case the amplitude is also varying every 1/44khz second. And well, varying the amplitude of any fundamental wave that fast is… what a single speaker already does. So the resulting sound will actually be summation of 20 bandpass filters (but spatially distributed in height). This how MP3 compression works btw, but it uses 20, 000 bins. I’m not sure it’s audiophile but I would sure love to hear it!

I'm so thankful that this is not what it takes for hifi music. Last night, I sat in a most immersive sound envelope into the wee hours with a meager pair of 5" 2-way speakers near field. Otherwise, none of us common folks would likely be able to afford just the crossovers.

As an Electrical Engineer I've done many Fourier transforms on paper. This is very unique to see an implementation in physical form. Very innovative and creative approach.

SO WONDERFUL TO SEE ENTIRELY FRESH THINKING STILL STRONG -- KEEP GOING !!

[TravisTennies]

I would offer to master your audio but you will probably say you hear nothing wrong with it. Amazing how I hear something like that every time .... Truly amazing.

[FunRunEndsInTragedy]

I’m really not sure what to say or think about this. It’s just brilliantly mental.

[evzone]

That's cool as a thought experiment, wild as a science prototype experiment, but the fact that it works well enough to market is incredible. Keep thinking outside the box.

[brucermarino]

I recall seeing a similar concept back in the 70s. Thanks and blessings!

[pmbouvier]

Looking forward to seeing more of this; multi-channel DSP is a direction I have interest in. And they look great, too. Thank you!

[k.c.sunshine]

Wow. That's incredible! One improvement is to suspend it on lines connected to the ceiling so that it can pivot out and point the highest one their directly to the listener; kind of like a sound cannon.

[TheBrooklynPipe]

This is the way. Different drivers for different sections of the frequency spectrum. I've been saying it for a while. Glad someone got around to putting it into practice and I can't wait until it catches on.

[jjinglenuts]

I am into DIY speakers since 80's i have made many same kind of speakers, but in my experience, 6 way is enough. Each driver produces smooth, bold, and natural sound.

[mortezazamani]

when creativity come to life. amazing piece👍👍

[carstensommer]

without a baffle for the drivers there will be a huge amount of acoustic shorting and the speaker will also have very low efficient
