This guy really knows his stuff about building enclosures ! I am in the process of finishing up an install using an enclosure design created by him , and although i still have some fine tuning to do to the amps...everyone that has heard it thus far are trully impressed and cant believe 4 10" subs are producing that much sound !
These are great tips, I recently built my first bass box using just hand tools, and it turned out well, but I had to do a lot of hand sanding to finish it. I also used simple binding posts to save time and money.
Great video. I always have my panels sawn to length by the DIY store. But I too had issues with panels not ending up precisely the right size, so last couple times I account for that in that I have some specific panels made 2mm bigger on purpose so that I can make everything fit nicely using a router and flush trim bit. What I also do is draw out the panel cuts for the DIY store guy, so that the saw doesn't have to be reconfigured to saw different panels with matching lengths / widths.
Screws can (and IMHO should) be removed after the glue is completely cured. Then drill out the holes to allow for dowels, or fill them up. Just make sure there will be no air pockets!
Great tips! Another tip is when you have to cut two identical panels (I.e. front and back panels) tape them together with double-sided tape and cut them together.
I use a circular saw to tear down a plywood sheet with Kreg Rip cut guide. No matter how much you try, there is a chance that there are some boards which are not perfectly square and some edges which are not perfect 90 degrees. I end up using a Flush trim bit with a perfect square board as a template. Since I am tight on storage space and have no place for a table saw, I end up spending time on making the edges square, with a flush trim bit, which also makes the edges as close to 90 degrees as possible. I bought a lot of clamps (still not enough :) ), and I do end up gluing the whole box together at once (without the baffle though). I built the speakers called "Continuum II" this way and a sub woofer called "Baby boomers" following Jeff Bagby's designs. This is obviously more time consuming, but quite accurate. I also make sure to get router bits as well as good saw blades. This way my plywood sheets don't tear. And the results are quite close to accurate with smaller tools. Thanks for talking about the 90 degree angle problem :) That is a great advice. I did mess up my first box since I was assembling panels 2 at a time, and had to redo all of it.
Great job on the boxes but I just wanted to know if I have a ported box specially made for port can I still plugged it and it’s not what happens if I plug port?
@@AudioJudgement thanks but I asked the company if I can do it and they said no. I wonder why they would tell me know instead of go ahead and try it out .
I mean, it's expected to have worse performance, so they are not encouraging you to do it, but there is no problem in doing so. There are speakers which come from the factory with dense sponge plugs and you can convert the enclosure from bass reflex to sealed if you wanted to.
I use T-nuts or those things you screw into the wood with threads for the drivers. That way I can remove and install them without worrying that wooden screws will eventually come loose.
I'm kind of tired of building my own speakers because I'm not very good with the finishing , but at the same time the speakers you buy are pretty lousy. The drivers are cheap , the crossovers are terrible and even the box is usually lightweight unless you dish out big big money.
Screws in MDF endgrain is never a good option. Glue only is fine, maybe use a couple of nails so the panel(s) are not sliding - pull the nails back out later in case you want to modify (cut) them back down someday. The use of weights is very handy for box building, if you have the time.
idk if this is a stupid question, but something i just thought of, can you use 2 ports of different leingth to get kinda 2 tunings, each perhaps not as good as if it was just 1, but both would resonate at different frequencies and perhaps?
Nice video! How about using gasketing tape between the enclosure and bass reflex port? If you screw it tightly, the tape will not allow rattling sound and it seals it perfectly at the same time. Or do you have another experience?
It works, but I like silicone better as it acts like an adhesive and the port is not fixed in alone screws. If you want to use screws and gasket tape, I suggest to drill more holes into the port and use more screws (6-8 not just 4).
@@AudioJudgement i see.. you are right, it completely makes sense.. silicone properties are incomperable with the tape.. I am now in phase of designing my first speakers. If I go with port, I will try your tip!
Normally, wood glue should be enough for sealing things up. However, if you want to add silicone to the inner creases, that can only be a good things, as there might be tiny leakages which will be fixed.
I was lookking at bolty Binding Posts online, and for most the body is just brass, but gold-plated and they are very affordable. Looking up Brass in electric circuits, it is claimed that it delivers only about 20% of the conducting of pure Copper. Now is this gold-plating make this cheap binding posts still good binding posts, or do I have to go for the pure copper ones, if I want to have a good binding post?
If you have a very high-end audio system and think that the binding posts material will make a difference, go for copper ones. If not, I don't feel like it's worth the hassle. The fact that it's gold plated, has nothing to do with conductivity (gold is worse than copper in terms of conductivity). Gold is very soft in its natural state and it assures a good contact when pressed against another material.
@@AudioJudgement Thank you for sharing your point of view on this topic. 👍 I don't like both options, one for the signal-path's sake and the other for the costs. I just like the Idea to make all as good as possible limited only by my capabilities. So I will separate the crossover inside the speaker from the rest of the speaker-volume and make it accessible from the back of the speaker, so the cable from the Amp can be connected directly to the crossover. Case closed.🙏
Very good tips. Though if anyone tries to get their stuff cut at Home Depot or Lowe's I'd recommend simplifying the cuts as much as possible and bringing a tape measurer. And avoided getting any cuts done by people who are in any way rude or grumpy. They don't care about you and your cuts and will screw It up. (Or maybe bring a snickers for them if they are) My cuts were so far off I couldn't fix them after the fact because they were both 1/4" or 1/2" too short and too long. I could fix them if they were too long. But too short made it worthless to me. I ended up finding a seller of higher quality Baltic Birch Plywood thanks to that though. So that was a good thing. The plywood seller also cut the plywood for a small fee with accuracy so good I'd say it was within 1/8th of an inch to my dimensions I provided. I did provide a cut sheet which helped simplify the job for them. But they had a very fancy saw thing that made it easy to do that. With all that said if anyone even reads this far into this. I have also had a great experience with Lowe's. The person there that day was wasn't rude or grumpy at all and felt like they were at least happy to be there and help. So the cuts they helped with were pretty much within 1/4" which is more than acceptable considering I just needed a couple of panels trimmed down to fit in my suv to be further cut on a friends table saw.
I'd just like to add that giving them a tip when the manager isn't looking couldn't hurt either. Most of those employees aren't paid much and have tedious jobs, so doing a whole bunch of extra work for the same pay can be rather annoying. I have been in that scenario lol. I never expected tips, nor would I give a crappy cut because I was annoyed, but I can see why someone would. Especially for a very persnickety customer. My company actually charged extra for cuts, but I didn't get anything out of it myself lol.
You can use screws or staples. In my opinion they are quite optional. Unless you don't have clamps. In that case, they help in gluing the panels together.
For my work so far, and granted I've only been at this for a few months, but I've settled on "Gorilla Wood Glue" and it's turned out to be a better product than other glues that are almost 50% more expensive.
If building vocal pa cabs, wedges, or bass/ guitar driver cabs, ALWAYS USE SCREWS!!!! These are not sitting in a room for 5-10yrs, they are heavy duty cabs. 12mm+ mdf glued, braced and glued, handles can be added as made, or a long oval if its not sealed. Corner cover bits and carpet keeps them flash, or just spray your cabs matt blck, (after sanding corners back a bit) Then get the guy that drew that sicklogo with a skull and wings and inverted crosses that nobody has bn able to work out yet, and Varg's yer uncle. Also these may need to be wired using 1/4" plugs like guitar leads or balanced canon plugs. Just make sure you test on a large amp, this avoids overload clipping, and as long as before distortion you later get a call from noise control, the 'annoy shitty snob neighbours' circuit is funcioning optimally
Great vid buddy. I’ll give you a tip if you or your viewers watching didn’t know. I hope your wearing a good quality Dust particle mask. That MDF is some seriously nasty stuff. Don’t take this as a joke please. Regards Mario 🇦🇺
I have been taking this a bit more seriously. Got a 3M mask and I try to wear it always while in the workshop, regardless if I cut something or not. Thought about fancy dust extraction, but a good mask is cheaper and more effective if wore properly,

I used wooden pegs first before I glued my speaker box panels together. I sanded down where needed and it went fairly well.

Any idea why we don't see any Midfield DIY active crossover 3-way designs. Like at all?
Any recommendation on wood type and thickness?
Great job on the boxes but I just wanted to know if I have a ported box specially made for port can I still plugged it and it’s not what happens if I plug port?
Then you’ll have a perfectly working sealed box. Presuming that you plugged the port correctly and there is no leakage.

Ported enclosures are mainly for subwoofer. So, yes, I'm including subwoofers as well.
I use T-nuts or those things you screw into the wood with threads for the drivers. That way I can remove and install them without worrying that wooden screws will eventually come loose.
How do u usually clamp port spots if it's near the middle of the box with clamps
Excellent advice!

Finishing is a skill, don't get discouraged, lots of great videos on you tube regarding wood finish, practice.

I always put a small bead of silicone in all inside corners. I like to know without a doubt it’s sealed right.

Rounding edges is always a good idea. Flat can work if port air velocity is not high.
