Fix this mistake to make box building easy!

[@DIYAudioGuy]

Everything just fits better.

[@jamesblake3090]

I was short on time before a build and wondered if there was a version of advice to watch, without all the sidetracking extra commentary that makes a 5 minute tip into a feature length film. None to worry if it's thought of as too fast to comprehend, that's what pause and rewind is for. However additional content is rewarding, just not for those pressed for time. And yes, it's known that the forward button or advancing the video is helpful, but then it's guessing where to forward to without missing information unknown. So then it's back to the "slow-show". That said, I'm a huge fan, and have used tips by this guy for a while, and have been in cabinet building since 1985. So while I have a good knowledge base, anyone can still learn tips and new things always. I humbly post this, with great and honest gratitude

Kids, in whatever you do remember to measure twice then cut once. Measure twice then cut once.

[@stuskustomshop]

Absolutely great topic! One thing I will add from my experience; I always design the face that contains the port as a single piece (that’s to say the port wall end is not exposed on the outside of the box.). The reason this takes priority for me is that I use a jigsaw to rough cut the opening for assembly, then a router with a flush trim bit to finish the hole once assembled. This allows for the use of a round over on the port mouth as a final step, and prevents awkwardness from nails or screws when making the pass as they’re always on the face and the bit’s bearing doesn’t have to ride over them. 😉

[@DIYAudioGuy]

Pro tip for sure!

[@shawnsanderson3695]

I'm definitely going to start doing that now

[@wilsonrawlin8547]

EXECELLENT TUTORIAL! If you don't have a cut guide tool or table saw. Clamp a finished piece 2X4 or other very straight board, straight edge, etc. along your cut line so the circular saw base plate slide down it and the blade cuts perfectly straight from start to finish.

[@DIYAudioGuy]

A straight scrap of MDF or plywood also works. Anything straight.

[@arnicus208]

I recommend using glue and screws no matter how long you’ve been making enclosures for high pressure applications. Over time, screws will hold more securely than using an air nailer due to the added surface area of the screw’s thread and how they lock into the wood’s fiber.

[@DIYAudioGuy]

For big builds with powerful subs, yes. Plus use a lot of internal support, braces, battens, etc.... For a pair of 10s or 12s under 1k watts. Glue and brad nails with some bracing is fine.

[@jeremynelson8496]

Wood glue is significantly stronger than the wood itself. Screws or nails are just there to hold the wood until the glue dries. I think screws will give the most fudge factor if your cuts aren't prefect though.

[@bkrgls]

Tracks saws are awesome too. I use my track saw for the long cuts and my table saw for the short cuts because I dont have a place to set up a spot for my table saw to be permanent. And i still prefer the screw and glue method with clamps. I use the SPAX MDF screws. You don't have to predrill any holes, but you still have to be careful of screw placement. Even though they are narrower than drywall screws, they can still cause the wood to split if they are too close to the edge of the adjoining piece. And another thing to consider and it doesn't matter what type of saw that you're using. You have to keep in mind of which side of the line is going to be cut. You can easily come up short by the thickness of the blade if you're not careful. If you're super motivated, you can use a 4 ft level and a circular saw to make good str8 cuts. Once you get the measurements down for the distance from the edge of the 4ft level to the cut side of your blade...you're good to go. Just make sure to clamp down the 4ft level before you start cutting. 😁😆✌🏾

You can also allow more bass to sealed boxes over ported boxes. Again speakers last longer in sealed boxes then ported boxes. Do the test for yourself you will see more bass output in the sealed boxes.

I use a folding (hinged), 6'×10' support table (which supports the entire 4×8 sheet). And a rigid saw guide, having an intergrated saw support and high volume dust collector. This is less cumbersome than a tablesaw (even with an extended table). Very fast and easy to set up! I only use a tablesaw and sliding tablesaw sled for smaller panel pieces. Another handy tool are sets of labeled spacer strip pieces, in common stock widths - zero measuring!

Own both a Bosch contractor saw, and the Kreg Rip Cut. Use them both as follows. The Kreg Rip Cut is actually much better to break down larger sheet stock than a Contractor Table Saw. And also much safer. Once the 4x8 sheet is broken down. the table saw takes over with the smaller cuts. Contractor Table Saws, and Cabinet Saws are not the same...

[@dreieinhalbeck]

Another Tip for easier box building that I learned the hard way: don't create complex shapes with triangles and wird angles. I did it and it cost me an extra 15 hrs. compared to an easy layout. In my case it was Wörth it since I absolutely wanted a sub that distributes bass evenly im my entire room ( tried it with another sub and ideal position was in a corner with 18° angled sideways and 11° angled upwards.

[@DIYAudioGuy]

Absolutely.

[@dreieinhalbeck]

I should probably clarify: I've got a roof slope in my room that works like a horn, thats why the angle was chosen so precisely, as to maximize the horn effect. The sideway tilt is there because on the other side of the room there is a big wardrobe vwith a bookshelf (with books) that acts as a bass trap. I could have just put the sub to the opposite site of the wardrobe, however, for a single sub using a corner is better to fill my room. For 99.9% of people out there, going to such lengths is NOT necessary. It's just the layout of my room that allows me to take advantage of such a complex box design.

If you are going to make many boxes and want to do this on a regular basis, the track saw is the way to go leaps and bounds above a table saw. And by far most accurate if you can measure with a tape measure. No man handling the sheets just lay the track from the track saw on the sheet and cut with the saw. Festool and Makita both make great saws and the tracks are interchangeable too. Work smarter not harder!

I wouldn't use silicone to seal boxes. Wood glue or wood construction adhesive only. Silicone sealants have solvents that offgas as it cures. The solvent fumes can soften the varnish on your coils when they get hot and cause premature failure. You can use it, but wait a full day or more to put your subs in the box after building/sealing it. Then blow it out good first.

[@DIYAudioGuy]

Good point! I should have mentioned that in the video. You absolutely need to let the silicone cure so you don't mess up your speakers.

[@wally7856]

PL Premium construction adhesive (regular 3x) is all I use to build boxes (and I build a lot of them). It expands as it cures to fill joints airtight (so has to be clamped or brad nailed to hold the boards in place or else the expansion will move them out of alignment). Your cuts can all be 1/8" (or larger) off and it'll bridge that gap no problem as it is very thick, solves all sorts of cutting sins. Use lots so you get good squeeze out on every joint and you'll be airtight. Don't clean up the squeeze out right away, you'll make a BIG mess. Instead, leave it and wait about 6-8 hours for it to set up but still not fully hard and then you can easily scrape the squeeze out off CLEANLY with a scraper or chisel or even a 2" drywall putty knife. If you get the timing right you'll have very clean looking joints. Don't wait too long or it'll become quite difficult to remove once it fully hardens. PL premium also creates as an incredibly strong joint after fully cured as it is a polyurethane adhesive. I build touring subwoofer boxes that are only held together by PL Premium, no screws or any other fasteners and these are 260 lb+ boxes that get tossed around on and off the truck after every show and they hold up no problem. Oh ya, wear gloves or your hands will be black for a week.

dear friend need a help with a 10"x6.5"'x18" box. what is the suitable sub speaker size and amount for this, plz advise

[@BrandonBuckaudioanarchy]

I don't disagree that the fewer number of cut setups possible is a good idea but I wouldn't prioritize it over structural integrity. For instance, on a double baffle. The inner baffle should always be an inside board, such that the sides, top and bottom attach to its end. Then the second baffle layer should overlay that such that it creates a herring boned joint on all sides of the double baffle. This creates a much stronger joint partly because it increases the surface area of the joint and partly because it creates both sheer and tensile stress on the joinery. When I build an enclosure, the top and bottom (or front and back) will be the same size and every other panel in the build will be the same dimension in one direction. And with center ports, you'll have two of each panel in both dimensions. And there are more advantages to center ported enclosures. The center port creates a brace in the center of the enclosure, which is very important, but I see a lot of guys building enclosures with two subs in them and the port is all the way to one end or the other. You're throwing away a free center brace when you do that and, if you lose a sub while playing, it doesn't put as much stress on the one that's still playing. If you have straight cuts and good wood glue there is NEVER a reason for caulk of any kind. But if you must, silicone is just about the worst thing you can use. Silicone sticks to nothing... not even itself. If you need caulk, use painters caulk. It doesn't stink, it's much easier to clean up and it actually bonds to wood. And last, if you're using MDF, don't use screws. I won't even use them on plywood but it is especially important to avoid them with MDF because they will split the wood and weaken it. And the only way to avoid this splitting is to predrill the holes so large that the threads don't engage the material. I've built everything from simple computer speakers to 40kW SPL builds and I never use screws in the end of a panel. Also, keep any fastener 2" from the end of a panel. I know it seems like you're doing good by putting them all the way to the corner but all that really does is split the material in two directions. This comes from a manufacturer's instruction on MDF, not from my personal experience but only because I happened to read it in 1990 or so when I built my first enclosure from MDF. Before then we used particle board, which isn't fun to work with at all, lol.

It is hard to get loud and low bass out of a speaker that small, and out of a small enclosure. A port will help, but small boxes require very long ports. So either go sealed or look into using a passive radiator.

[@Grommet2007]

I'm a pretty horrible box builder, LOL. For a number of reasons, including my eyesight. One thing I try not to do though is end up with a box design that results in a situation where, during glue-up time, a piece needs to be slid into place, rather than pressed into place, and when pressing a piece into place, I make sure to use enough wood glue to ensure that excess glue is pushed out from both sides of the edge that's being joined. Finally, I wipe the excess off from both sides of the edge with a damp cloth. This ensures a strong and airtight glue joint.

Is it possible to use to much glue?

[@LeeLee-fi7mx]

I find the easiest and most accurate way to cut wood for an enclosure is to let my hardware store do it. Most hardware or lumber yards where you buy wood from offer cutting services with equipment far more precise than what a typical homeowner has. Sometimes there's no extra charge to make the cuts.

[@DIYAudioGuy]

Both Home Depot and Lowes in my area will do two cuts with their panel saw free of charge. The accuracy is entirely a function of the employee running the saw.

I should really get myself a circular saw all I've ever used is a jigsaw 😂

[@DIYAudioGuy]

That might make life a lot easier.

[@SilmarilS79]

Just clamp a bubble level as your guide for the skill saw...

[@jeffu3248]

Awesome!

[@DIYAudioGuy]

Thanks

[@DCBChump]

Screws are not just for beginners. I've been building boxes for 25 years and I still use screws whenever possible.

I want to add on to a sub box particularly not finished and I want to add length the the width can you possibly get your hands on a 350z 2003-2006 and make a custom build for it I could really use the help threw a video I'm a hands on kinda guy and I like your videos

[@DIYAudioGuy]

I wish I could get my hands on one!

[@bogosikereng5963]

What software do you use to design the subwoofer boxes

[@DIYAudioGuy]

WinISD and Sketchup

[@davesnothere8859]

a wen track saw is the tool for this and the cost less than a circular saw and kreig guide, about $120. for breaking down sheet goods i think tracksaws are better than a table saw. in my old age I have realized the tracksaw is great for big things and the table saw is for small cuts.

[@DIYAudioGuy]

A truck saw is a great tool.

[@poohwecampbell7799]

Do make custom boxes ??? Please say you and have a way to order for me !!???

[@DIYAudioGuy]

I do not, shipping is a big pain so I don't do it.

[@shawnmccalmon1052]

Hi I have 8 6" speakers I have 4 mid-range and 4 vice and I want a make one box to accommodate all the speakers for my home system can you send me a diagram and measurement to build one thank you

[@DIYAudioGuy]

You will need an internal crossover network for that. Those can be complicated so I charge quite a bit to design them. I recommend that you join TOIDS DIY forum, they can help.

[@TheCalvinSkinner]

GRADE A advise! thanks

[@JimmieBattle-tj3rn]

I want to build a self-powered dual subwoofer two of them

[@gsxroyce256]

[@MannyGunzz]

Slow is best take your time... But enough glue and screws it will still work..
