I am a pretty good box builder myself 30yrs+ and im still learning new things from your channel💯... Good Work

I built the vented enclosure. I have the same dayton speaker. It sounds great! Thank u. Keep up the great work. I love this channel

Dude you are the greatest Parts Express salesman. I watch you videos and instantly got to parts express website. Great stuff

To seal up a removable panel, what I use is "Composeal". It's actual use is for making shower floors watertight. It's really thin at less than 1/16", is super cheap and available at any home improvement store or plumbing supply house.

Man I love your content ,best dude on budget audio, and man you got some awesome build skills

i built a fourth order band pass but with a 6.5 inch speaker. Just up the size accordingly. I am using an 80 watt amp i also built. It sounds awesome. I added some blue led's in the back of the port that light up the darkness in the port and wired them to blink to the beat of the music. Thanks for the video. PEACE

Really enjoy your video. Been building speakers for 30+ years. I have a fondness for bandpass and folded horns as well. Also transmission lines but so difficult to build and calculate. Decware has great cheap not free bandpass plans, very highly recomended.

Hello! Nice channel and information dude! I'm from Chile and I'm obsessed with 4th order bandpass for mini subs since the 90s with Aiwa old home mini hi-fi systems!

I like how clear and concise you were while still being thorough. Some advice on the threaded inserts though, put a couple drops of wood glue on the outer threads so they won’t pull out easily because those tapered inserts are going to pull out of that thin particle board so easily.

Hell ya iv been waiting for this vid. I love the content😋👍

Love the mini builds! Loud bass from smaller subs is always more surprising than from the bigger subs. Would be cool to see you make a box like the the Bose Acoustimass 15 ii

Nice work. Thnx for your time and effort. This is going to take my Bluetooth builds to the next level

Glad to see you going for that folded horn build. I suggest when you go full Transmission line that you do it with a 12" woofer. Do a reaction video when testing. I love to see the joy that appears upon completion and hearing it for the first time. Thanks for your amazing videos sir!

Best feeling is having all your pieces cut and ready to put together.

Very Clear descriptors. A lot of variation covered. Thank You.

Man thats cool ,youve got every measurement, every setup and nicely done. you definitely know what you're doing...👍

I just wanna say, your way of tersting this is a lot better than most peoples, and I didn't expect the porting to do ALL THAT like wow, makes me wanna make a ported box for my 8 inch goldwoods

I love this kind of content. I'm really curious to see how the 4th and 6th order band pass compare to the vented enclosure. Nicely done!

So cool you did this.

I’m pretty sure that you actually have 1/2” particle board instead of MDF. MDF is very tightly compacted and comprised of basically dust sized particulate matter so it won’t have that rough grainy and crumbly texture like particle board. Particle board is compressed and glued like MDF but it’s particulate matter is much larger in size and the particles range in size unlike the uniform particle size in MDF.

Thank you for your videos!

Nice video! The little boxes are nice. And the music was good!

I'm so glad I found you!

B R A V O to you Sir. That's a very good job. Cheap, small, quality builds. That's something.

Sweet... Thought I was the only mini obsessed builder lol love bandpass as well, pure depth.

i must say i do like your videos man, good info and effort into this video.

Thank you for posting, LOTS OF GREAT INFO HERE!, i did car audio for about 8 years back in the late 80's to early 90's, and built many enclosures, tech was not nearly what it is today, used an old RF nomograhm (sp?) for port info, one tip, a really good jig saw will make your life much easier, i liked the De Walt, BE SAFE!

your build goes soooo much deeper than the bought one, much nicer sound =)

Dang so the Pioneer is powering your build? They go hard! Love the effort you put in!

Those Dayton MK 402x speakers sound good when powered by that 2.1 plate amp and the 6 1/2" subwoofer kit from Parts Express.

Great vid man, i gotta say you put alot of time and effort into this video and we all appreciate the content. I can tell a big difference between the audio on headphones. The ported box you made sounds louder, and just goes to prove that the box makes all the difference. I would like to see you try the 4th and 6th order boxes as a bookshelf speaker and put the crossover inside and tweeter in the front. I liked the video alot!

Great vid, thx for the effort!

Thank you great video 👍👍👍👍👍👍👍

Excellent video my man

Hey there, I like your content and you clearly have a great knowledge, experience and most importantly you have a passion for your trade, so yeah man good job. Now I have heard that while band pass boxes really are amazingly great with the deep bass, and I speak with experience of my own as well with a 12” Sony sub. Mouthwatering bass! Problem was that you didn’t really hear it from outside the car. Also not very stable. I’m looking for something, more like a ported enclosure for nice all round performance. I’m running a Jbl 10” Shallow mount Club1000 which has a nifty switching built on it for switching between 2ohm or 4 ohm as you prefer. I’m rocking that on a Kicker amp, 400rms I think. 2 ohm monoblock. I’m really struggling with space to make use of. I use my van as a private car and also for work, so I can’t use loading space. Is love to chat more if it interests you. I think you’d be interested in my work I’ve done so far. All outside the box thinking to challenge myself to be unique and still maintain my budget limits. Take care, and hopefully you can respond back

Would a 4th order work for 2 DD 6.5’s? Like your box, but mirrored so one sub is on the left in a sealed chamber and one on the right in a sealed chamber, then both sharing one common ported chamber. Or a 6th order again with them sharing one common middle ported chamber with one left ported chamber and one right ported chamber.

Great video my friend, can you plot the responses in Smaart or REW for a better comparision? Thank you

Awesome! Would love to find plans for a 6th order for a dual 4ohm 6 1/2 low power but space is the case. Any ideas? Gonna install in a golf cart. Ha!

if i am making a new 4th order box i want to have the top in acrylic i think that would look sick and you see the sub moving

so what is the dimmensions on the box for the 6th order? I see the chamber sizes but not the box sizes anywhere. can you provide these?

Just started this video and ive used 4th order boxes in the passed when i didnt have any idea what i was doing. And i still dont know exactly what im doing. Lol i wanna build a system that plays hard hitting rock bass for dubble kick drum bass, and still good for the rap low bass sounds i also love to listen to. Ive thought about using 2 8in in a sealed box and a 12in in aported box all together to get all the bass. Lol what your thoughts ???

How do you design the geometry of the speaker boxes?

Definitely hear a difference. Since box is designed to play with a bit; I would like to see if there is any difference if you add a bit of poly fill to the box. Just for experiment. I really appreciate your videos. Always looking forward for more.

can you test the other two for comparison?

You do a great job on the video's

Love the videos. Suggestion, Pick up a couple of cheap corner clamps from harbor freight instead of using a speed square or whip up a jig if you make enough boxes No more fighting with them and you can make sure they will be 90* every time.

Also id love to see a passive radiator build with this little sub

i'd like to make a box for my 2 dc-160-4 6.5 in speakers, a 4th bandpass, but i'd like to have the speakers face each other behind a clear window. would i be able to just add the volume of the sealed chambers together and have the subs firing at the same time (+,+) or should they be treated as isobaric in the joint chamber (+,-)?

Very Good!..

bring out the coffee.....good job

I also recommend counter sinking and glueing your insert nuts. Note longer bolts again.

I just got a hcca 122 and getting a bandpass built i believe its a 4th order one port idk just wanna do numbers out the trunk doing two tens a horn and tweeter's should be golden on sound and a jp43 or a true 4k amp

I know this video is old. But what I did for my removable panel seal was a sheet of 1/16th cork that was attached to the removable panel with contact cement. On the side facing the box I painted a thin layer of thinned down silicone. it was just regular ge1 silicone that was thinned down with denatured alcohol. it is mixed down to a paint like consistency and painted on. Once the denatured alcohol evaporates semicolon you are left with a 100% silicone coating that is literally bound into the cork fibers because the denatured alcohol also helps it absorb into the cork. I use this combo to act as a seal and also as a binder to hold the cork from deterioration. I've never noticed an air leak or any deterioration of the material or delamination of the contact cement even with multiple disassemblies of the box. I use the same silicone coated cork for gaskets for my speakers as well and I've never had a leak or an issue with breakdown or deterioration. Even used it as a seal on plexiglass viewing windows and terminal cups, again with no signs of deterioration. It's basically just a silicone seal with the cork acting as a compressive lattice. It has worked well for me as a seal for many years.

Can you do a sound test? Between the 4th order and 6th order. Would very much like to hear the difference between the two.

I've been wanting to put 4 ported shallow mount 12s in my van and still have room for passengers.

I would like to know if a 6th order wedge box be built

Would that be an easier build using pve pipe for the ports? I built an. Awesome 6th order for an 8" years ago that n sounded like 2 12"

On a 4th order is there a difference as to which part of the subwoofer goes into the sealed chamber? I've seen boxes where subwoofer fires into the sealed chamber and others where the magnet is inside the sealed chamber. Does it not matter?

How do I get in touch with this guy. I want to buy plans for these boxes.

On the 6th order, would you see a db improvement if you put the out of phase ports facing opposite directions? Sub newbie here.

I have a 6.5" Klipsch sub that I want to do this to. It has a rating at 65watt RMS and 100watt peak.

hello, great video! however, do you have the dimensions in cm please? I have a dd audio 6.5. PS: I'm from France. :)

The the speaker a dayton audio tcp115 ? Because i have 2 of them im interested in building a better box for it

Sketchup isn't free any more, but I did use it to design my first boxes. I used FreeCAD now and I generally like it for designing but there's limitations in texturing and fancy stuff. I don't mind.

I am needing to make a small subwoofer for a guy. I made a small Bluetooth radio for him awhile back and now he wants a powered sub to hook up to it. I have a bose 111791-k driver out of a accoustimass 25 that I need to use. Not sure what style of box will be best for this guy. Anyone have suggestions? This was a great video....now I'm more confused. Lol

That intro tune was straight out of a British home design TV series

Great Stuff! What program did you use to get your designs? Is there a 6th order calculator out there? I'm interested in the 6th order box but maybe with a 3" or 3.5" woofer.

Great video and videos! You do know how to be low.... :-) Q: If I use your mesurement of the 6th order bandpass, can I turn it into a 6th order bassreflex? Same port length. Get the same low bass, as you have calcultated?

can i get measurements for 8inch woofers and subwoofers

How do you add speakers to your enclosure in sketchup and is there a good tutorial?

Can I have get the measurements of 8",100watts,6th order subwoofer?

Do you sell and ship these boxes?

I have a black and decker jigsaw that’s probably 10-15 years older than the one you showed. It’s made of a really smooth shiny plastic that is that ugly puke green that was popular in the mid and early 70s

another trick on getting the wood to not split instead of vice grips is to hit the screw or bit with a torch and go i slow. works magic.

Can you please say the title of the 2nd to last track.

Hi. I am glad I found your Vids. I am just building a 6th ord bandpass because of your inspiration 😊 I got a question. What’s the app for the decreasing frequency output ? Thanks Matthias

Would you have any plans for 6.5?

Love the builds. I'm sure you've heard this before but you sound like Steve Harvey

Please what your ratio for the 4t order

can i get the blueprint of 4order banpass 4inch

Use a drill bit with countersink on it if you're putting in metal screw inserts I think you should have taken the internal baffle port right up to the top of the speaker giving you a quarter wave transmission line. Plenty of of dampening material go with natural wool fleece

can you do one of this boxes with a 6x9?... please!.

Nice

Do you ever sell any of the subs you test to fund other projects?

Sir, I need a design of box.

what was the test music?

Make it a subwoofer only. Did you test the 6th order?

@ 39:06 Big "D" Wiz? Williston Audio Labs........

Enjoyed the video. The bandpass subs should stay as subs. Otherwise there will be a hole in the midrange.

Sir... 5"..?

Use the band pass boxes for bass only bro

Ok, so why do 4th orders sound so damn good to me but 6th orders give you a wider bandwidth?

Nice, do et!

He sounds like Steve harvey im just messing around lol but its an amazing video this is also something I've wanted to do but given my age im broke so thats always fun but wouldn't recommend but about the 3 to 1 if u want just loud yes thats the way to go but there will be a very narrow frequency response u may hit 60hz but anything before and after that u dont get a lot of let alone loud im not hating at all I love this vid but there is a guy that is on yt as well that did a video called bandpass myths and it explains what the ratios do from sealed to the ported side

I apologize for having no helpful input for the video ending question, but I will offer an opinion. I would defer to the most qualified man - you - and do as he sees fit. Either way, I gotta see/hear what happens. I am constantly building sub boxes for small single cab 4X4 trucks, and just recently (sad) discovered from channels like yours : I had no idea how important it is to get it right.

Start every hole In reverse. And then you won't get splits. With mdf you can do the entire hole in reverse

Do u build And sell

Which one is your favorite?

Damn bro i think u could mount a headphone in a shoe box and make it sound good
