Sound in every direction 

Ooh sun kil moon! And that's my favorite Fleetwood Mac song!

Cool build! I've been wanting to make my own omni speakers and this gives me some great ideas! The speakers really look great as well. Props for Sun Kil Moon too

I feel like this enclosure with a nice full range driver and proper EQ would be amazing

Good effort mate 👍

Great ideas. I play solo guitar and find that traditional guitar amps are very directional. Something like this would be a great solution!

I've just gotten my first decent speakers recently. I couldn't afford a good full surround sound set yet, but the salesman talked me into buying a pair of speakers with an integrated amplifier to hold me over until I could. (Hearing the demo unit in the store in-action was what really sold me, though.) The sound quality is so delightful that I don't want to play any games with great soundtracks in the middle of the night when I can't use these speakers for fear of disturbing my neighbors, and it sounds much better having actual distance from the speakers than even with my open-back headphones. (GRADO SR60X.) However, the audio balance doesn't sound right unless I put my head in a very specific spot. I don't know whether it's the speakers that are the problem, or my placement of them, or that I need to get more (for surround sound,) or the fact that I have them mounted on cardboard boxes instead of stands... At the risk of having my purchasing decision judged, I'll tell you the model: YU4 from Kanto.

What a nice engineering !

thanks for sharing . great information .

Coole Idee ich würde es mal mit einem Breitbänder versuchen da die typischer Weise gebündelt abstrahlen und man dies dann besonders gut aufbrechen kann mit einem Kegel oder Kugel . Sieht auch sehr gut aus .

Nice building and very nice equipment.

Perfect job.

Fun project. A few tips, - that cone will not be seen as "rigid" over the entire frequency range, especially upper. I've made waveguides out of 3D printed PLA and PET-G but only for midrange as the FEA modelling suggested the structures stiffness to act non-linearly in the upper frequency range (depends on infill, size, shape etc). This will mean the cone is likley to resonante and absorb energy in certain areas at different frequencies and re-radiate over the inital signal and diffract. You will see this effect in the phase and group delay results as they are likely to look all over the place when this happens and may explain the random dips in your frequency response. You will also see random streaks in your waterfall plot. To reduce this, try ideally making the cone out of a solid ,dense and stiff material, (cast metal, concrete etc) or 3D print the cone, line with a thin compliant material such as silicone and fill up with concrete or plaster of paris, or at least print with 100% infil. The 2nd option will help dampen any resonance through shearing. - it's probably boomy due to the use of 12mm ply without bracing and an incorrectly tuned box/port. Again the resonances of the panels can causes interference and errors in reproduction. Try bracing the box a lot and try a different volume and port size. If you can measure the drivers parameters try using winISD to design the optimum box - don't measure with 2 coherent sources playing at once (both speakers). You will get phase interference giving an incorrect reading that will look like a comb filter.

Really cool thanks 😊

Amazing. Id love to have the time, resources, and knowledge to be able to make custom speakers. It just sounds like such a fun thing to do. I freakin love audio and have some decent equipment but nothing DIY, except the Hivi 3.1a which is a kit but they sound amazing for their price, even now. I want some Omnis, so bad.

I heard a Di-Pole Ribbon Tweeter, that fired in 360 degrees. It had that same Airness.. BUT... it caused all sorts of odd Distortions, because the highs were bouncing from every direction, and getting back to your ears at different time-frames. Sort of like an Echo effect... and ultimately.. it ruined the music. In my Opinion, rather than use a full cone... Use a Half Cone shape... so that the sound only emanates 180 degrees. That will limit the distortion of the image, drastically. Other than that... I always recommend using Sealed woofer boxers with higher powered drivers. OR... next best option, is using a sealed box, with a passive radiator. Both of those options will produce bass that does not sound "Artificial" and "Boomy"... which happens from Ported designs. But as said.. if you make a sealed box (non Passives), you need drivers with stronger magnets, and stronger coils... to be able to deal with the higher Air-Pressure levels. Otherwise, there will be no benefit.. and might even sound worse. (With the proper Passive setup, you dont really have to worry about that as much). The added benefit, is that a stronger speaker driver... will be Far more Accurate, and far less likely to Distort... even at its max potentials. Eco drivers are too weak... and so they often cant accelerate (and stop) fast enough to keep up with the musical demands (which causes the muddying distortions). Ohh, and since the speakers are near the wall... might as well have the Woofers Forwards-Facing... rather than pointing upwards, which likely will distort the highs. I theorize that it would be best to use a more Dense + Heavy material, for the half-cones, rather than plastic. I do wonder how a Curved shaped cone might change the Image projection.

Maybe try filling the cone with sand.

Wow awesome

Damp the cones.

I want o build my first pair of speakers. I want to build a pair of omnidirectional speakers so I am watching all I can. Even over the phone I can say yours sound very good. I'd like to take a Crack at a larger pair.

I really like your build! I have a lot of interest in omni-directional speakers and am looking for a project like this. Yamaha makes some really nice ceiling speakers (IC-400,600,800 etc) that look very much like a car speaker-they start at $100 a pair and I think they might be a good candidate for putting into a box. i’ll subscribe and see what you come up with next.

Thank you! I love Omnis yet no one sells them. You either got to DIY them or Pay for the high end ones. The OHM walshes are amazing but im not sure if theyre considered omnies. Anyways, The market needs Omnis! They create such an amazing sound field and would be great for home theatre surround applications and even stereo setups like these. Amazing build BTW. How did you source those cones. There not a common part neither is it possible to find them in the size you want for a build so it seems a 3D printer is a must.

How much cotton yarn did you use for it? I plan to make similar columns but 1 meter high :P

I am wondering if it might be better if the cone was more curve linear

Couldn’t find the stl files in the link provided please update or upload the files,thanks

You want to fill that cone with lead, not fluff, the idea being that your sound hits the cone and then spreads out evenly all round the speakers

Excellent idea, and fascinating build, but for prospective builders, look at "dock piling caps". Virtually identical to what he did with a 3D printer, cheap and commonly available. We are working on a similar concept for a guitar speaker. As a long time guitar player, having played on many stages in many clubs, a typical guitar amp projects like a laser beam, in one direction, and very little dispersion to cover the stage. An omnidirectional guitar speaker can play at a lower level, with uniform 360° coverage.
