just buy korean amps

So, I was a my first Bass show (idk what they're called). A guy had a box that he said was switchable from 4 and 6th order box with PVC pipe and some ball valves. The ball valves let him switch between them. How does one design something like that?

Out of focus...hurts my brain!

Binaural mike

Damp the cones.

have you had a problem with is raising on you since its just a floating gantry? theres nothing holding it from underneath right? Im looking at building one but I dont really like the V3 design.

I like your choices to used in your build i have purchased a few of the taramps ,brand my self . I have had interest in the ground zero subs as i have research they have very good quality.

Any chance of sharong this file? I wonder if i could modify it for a 3d printer.

PLEASE TELL ME: what is the difference when we have both ports in the same part of subs and when the ports are oposite? L-Acoustic made Sb18M with both ports in the same part but other brands (like KV2, Makie, Norton, etc) made subs with ports in oposite, like yours. Why?

I am sharing this video👍

I don't know if using a 30W class A amplifier would be okay?

Show vid of breaking them in

Do you have plans for this

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

Would this be ok with a 300a fuse? I need to make a block for 6 of them

Hello good day, can u tell me the measurements of it please?

if the fuses blow will the current flow through the plywood or is the voltage too low for that

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

What circumstances would you choose 4th, or 6th order over a traditional Cheby-Chev ported enclosure or similar setup using PR's? I'm a Home theatre person not car audio for context :)

Those full bridge amplifiers are not the best for subwoofers.

I would try hanging panels from all sides, via mildly tensioned Bungee cords.. That would be similar to a typical speakers "Centering Spider". I would think that you would want the panel to be able to vibrate / move fairly freely.. rather than being braced too tightly. That said.. you want to make sure that the movement would be accurate, rather than being able to move in random chaotic angles. The challenge might be, in be in making each bungee, at relatively similar tension levels. Maybe even having tension adjusters (like a guitar). Interestingly enough... Guitar strings might be a good suspension option. The use of separate panels for Highs and Lows, might help to greatly reduce merging distortions. Use a crossover, and direct to each.. and see what happens. Ohh, and the speaker wires themselves.. should be suspended, so that they do not add additional downwards weight, on the panels. The type of material used for the panels... might help in Optimization, for the High and Low panels. Meaning.. a different material might make the highs sound better... and a different material might make the bass sound better. Possible use of Zig-Zag material.. might help trap and move more air, on the Woofer panels... which might boost performance? All of this said.. Im not really sold on this tech... as interesting as it may be.

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.

What size bolts and nuts?

Pretty nice

Nice. Is it just hardware you can get at home depot?

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 .

Wow awesome

I want to build this box . I have 2 15 inch 500watt rms yamaha speakers . How can I get your plans for this box?

thanks for sharing . great information .

10:09 any knowledgde about this topic i gathered from my father, a goddamn wizard with electronics, yet also didnt see anything about it on the internet, its always just "wire low for more power", instead i did what you did, two series subs into parallel, giving me 2 ohms final at my amp, seems to work fine for years for me, even setting gain by ears, which is wrong but all of my gear survived all the beating i gave it, i aint got no money for anything more than just be careful i guess? greets from balkan

Wow, that lowrider is still going!

Выглядит интересно, гармонично👍. А почему именно такой вид и размер? Это связано с резонансом по частоте 432Гц возможно?

Good you're still posting. Cool project 👍

Look into getting a single, much more powerful 15" or even 12" sub, and then build an 8th-order bandpass for it. Even more bandwidth and musicality, plus with the meaner sub, it'll get even louder. Also, look into Hornresp for different modeling software. I've heard it does better when it comes to bandpass enclosures.

Perfect job.

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.

Nice work man

how long can you shoot in this mode?

Good job on the anl fuse holder. I will try this with abs, the warehouse behind me throws a bunch of it away going to take a piece! Appreciate the inspiration.

Good effort mate 👍

thats so bad ass

i wish i had the tools to bu id something like this

Maybe try filling the cone with sand.

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 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.

AWESOME SERIES!! Been modeling boxes for quite some time and up till now only built Aeroport Ported bass reflex - no bandpass. I am watching all the 6th order videos on youtube before diving in and building mine out- your series has the most content and troubleshooting!! I appreciate it

Your gcode problem is almost for sure being caused by RFI from your phase convertor. Those things (especially the cheap Chinese ones) can be a serious problem for any kind of signal wires. You will need to ensure it is properly grounded, and you will need to use properly shielded signal wires.

Wow. How are they holding up? It looks incredible

Did you ever get to upgrade to the deepcycle batteries? I'm really intrigued, always wondered how they would work in car audio, but nobody seems to use them
