nice skill in making boxes, I am a little behind in that, I made a 10 ct strato treo box, it's just painted black, and I tuned it to 35ish, the port is on right side towards the rear, rear seats delete coupe, put foam padding behind the box, with the subs facing forward and it sounds like it's tuned lower than 30, but again your box making skills are elite.
Bad ass brother can u post the cut sheet I would love to build that same enclosure for 3 sundown u8s for my suv thanks box looks phenomenal love the stain as well
Whew, my baffel was close between the subs on my last box....I almost cut it like that, so GLAD I made it work! Was going to use the damn grey stain on my next box, even bought all the stuff already, now Im not so sure....what kind of wood did you get? I bought Birch, sorry if you said already, i confess i FF at beggining!
Your enclosure looks real nice. Nice edges on the carpet. I like the wood grain being shown off a bit. However, I've got to say, 1800 is an awful lot of power to get a 138. Honestly I think you would go further having a sealed enclosure with two passive radiators. Willing to bet your SPL and your perceived volume would increase using less power having just one woofer... Would love to see you prove me wrong!!
I had just one. Then 2 and now 3. Yes this is really just an expensive experiment. However, it's an experiment that was relatively successful. As I stated in the early part. Losing some volume and adding power makes it have a flatter curve and still adding a bit of DB. It's hard to load just one of these woofers and be loud. The box I made for 2 was actually amazing. Every time I turn these woofers up, I'm impressed. As I've built heavy hitting builds, this one still amazes me.
A lot of the Lowes and Home Depots near me will not cut wood for a speaker box. A couple even have signs up saying as much. Most of the time that I can get them to cut it, it's been nowhere near accurate (usually crooked because they run the saw down and then back up without sliding the wood out of the way of the blade) Nowadays I just have them cut it like 1" over and trim it up on my saw at home.
Can't you just tell the store that won't cut sub boxes that you're building a cabinet for your travel trailer's bathroom. Seems legit! It seems shady that they don't want to provide service to all their customers, doesn't it? I would call the corporate offices on the offenders!
Great job Trevor. Just for kicks can you check the spl with the back seats down? I am just curious as to the difference you are seeing. I have (3) Sundown 10’s in a sealed trunk and found a 4db difference when the back seats were folded down. I sold my Meso 6.5’s and went with the 10’s but wish I would have just bought 2 more 6.5’s. Should have asked Bart for advise. :)
Give me your true opinion of the six and a halves please!! Kicking alot of different ideas around in my head before starting a build or ordering subs. Looking at sundown and skar 6 and 1/2s also. Considering 8-in CT and skar. As you can tell I'm kind of all over, so kind of would like some input. All my friends have 12s and they tell me I'm going to hate the 6 and 1/2s. , But I want to do something different not so boring that everybody has. Also My build will be in a four-door truck with almost no space under the seat so looking for some ideas there as well!! Thanks in advance
Hi Trevor awesome video and setup. Just curious to know how much would a box like this cost to build? I want to go with this same subwoofer and 3 seems really sweet.
Trever if you lean your box on its edge the glue want run out there pal, so you don’t have to keep lifting it back up over and over, lmao and lol. Great comedy bc you make me laugh
For a lot of builds MDF does work fine, the other gentleman is correct. However, in high pressure situations unlike this build, you would be better off going with Baltic birch or something of that level.. In situations with subs taking over 1,000 watts each I would certainly recommend going with the plywood, Double stacked. Maybe 3 layers deep on the baffle
In the video I talked about how I compensate for the kerf. I added 1/8" to my depth during the plan phase to allow me to take this space away. Worked out perfectly. Box has an exact tune of 36hz
@@ATCA I must have gotten distracted. That's amazing! It's the same tune I'm going for with a single Sundown X15 V1 build. Need to sound good playing a wide range of music.
@@v3zMedia Note that he said the kerf makes the port length about 2" shorter. You don't count the flared ends of a port when calculating the port length.
best channel.....I subscribe to very few channels due to time...and this is one....how much of a difference did you notice adding the super cap....and would there be any benefit to running 2 super caps? thanks and god bless
Know what’s good for making a radius (actually it’s an arc)? A compass. And they’re inexpensive…and infinitely adjustable. Beats using Tupperware and paper plates
I realize this video has been a year in the making however on your radius cut when letting the glue dry you should have propped the box up so the glue wouldn't have run down it would have stayed in The Valleys you cut to make your radius with maybe some painters tape on the edges to keep the glue from running out😊
Nice work man! I might of missed it. But did u account for putting the thickness of the second baffle on? I just saw that you put it on the interior of the box. Just curious. Such a great video.
Is bracing "required". No. Would bracing help? Yes, it usually can. If you look at his design you'll notice there are not any large panels to flex in the first place. Its a narrow rectangular box. If you look at 10:40 you see that the inner section of port wall is helping brace things top to bottom. All the panels look pretty stiff. Maybe the one place you could add a brace would be top to bottom behind the middle sub. If it were a larger box you'd see big gains by adding extra bracing. His small box almost doesn't need it.
Hi Trevor, Great build! I have a question for your thoughts. I have 3 Meso 8" subs that I will be getting installed in a few weeks at a local shop in Charlotte NC. My question is about the box build. I have heard that for a small SUV like I have, 2022 Mazda CX5 Turbo, that a box with dubs firing up and port firing rear may produce the best all-around sound. Is there any truth to that and also how does that setup compare to subs back port back, subs up port up? Thanks for your video and sharing your expertise! Thanks! David Ridgeway
Does this vehicle use a standard 12v battery to power normal 12v things? If so, does it use a DC to DC converter to step down the higher voltage battery pack to keep the small 12v battery charged?
Is that the harbor freight router? If so how do you like it? Also what bit are you using on the router to cut out the circles and what model jasper jig are you using?
@@ATCA lol ok.. I’m just looking for one that I can use to cut out the holes for my sub and maybe round the edges of my box so nothing crazy but it would also be good to have one to use for other stuff on future projects.
@mikeganard6751 This one is terrible for cutting holes. The collet doesn't grab tight enough even tho I have it as tight as humanly possibly. The bit will work its way out and ruin your holes. It also broke the latch and will spin and change the depth while cutting. So I put a grade I bolt in ot and I have to use 2 wrenches to change my height. Okay, so you managed to cut your holes without the bit falling out or the depth spinning.. Great, now you just want to change to a round over bit. 4 different wrenches, a hammer, and a chisel later, and you're good to go. That same collet that doesn't grab for shit also won't come out for shit. That's why today it is used for only cutting holes and its still not perfect.
So changing the port shape part way through the port (as long as you keep the same area) will not change the air velocity or increase turbulence enough to noticeably effect tuning, output, possible chuffing, etc? Is this dependent on the amount of change in shape, how much power you’re pushing or any other factors that you noticed? Any rules you follow to make this work every time? Interesting idea as I’ve always been told regardless of the shape the port needs to maintain that shape throughout the length.
I asked customer support for some advice but they said that because doing so would void warranty they wouldn't talk about it. Does anyone know if a custom subwoofer box for a 12 inch round subwoofer works for an L7S12? The Air Space cubic feet and the mounting depth all match. If I modify it by cutting the mounting hole to the shape of the Solo-Baric. Worst case scenario would be adding a thicker board over the mounting to give the subwoofer more depth to sit on. That all sounds like it's no problem. But would it affect the way it sounds in a negative way?
Hey I’m in high school and I’m new to making boxes well….sort of, I am but I have made a couple and I have done probably upwards of 2 days worth of time researching note taking and etc… I am a quick learner and easy learner I like detail oriented learning, I am wondering would you be willing to videocall and teach me, like yoga did for Luke?

@julesbruchez-outperformtra2020 watch the "how lous is 3 8s video. I clamped over 2k. I think 2200w or 2300w at 36hz. But I clamped right at 2k at 47hz There's a few factors at play here. I have a capacitor and factory agm. I'm running at .67 ohm. And the amp makes 2300w at 1 ohm at 13v. So at 14v, it makes about 2700w. At .67 it makes almost 3k. So after impedance rise of around 1 to 1.25 ohm, I'm seeing around 2k-2.3k
normally general rule of thumb you want your face plate of your box to cap your top ...bottom .. and sides... makes for a much stronger box.....it says very detailed... but never says how you tunned the port due to a triangle in the rear and rectangle in the front.. also did not mention what you think the box is tuned to....
@@ATCA interesting... how may square inches is the new port... didn't mention... how long is the port.. didn't mention... you said you shortened it... or how you calculated the port size with the triangle shape in the rear.... but I guess by taking one inch from the top... and adding it to the bottom makes all the other changes the same 🤣
@thomasstott527 port is 30 in2 from opening to the inside. It's whatever length the subbox said minus half the Kerf Radius. Thos box is 36hz wh3n built which I think is exactly what I modeled

That’s good bro nice job , I’m doing a small build Single Skar ZVX 8 not sure what enclosure to go with yet 🧐
Single 8s are hard. Because the port needs to be super long because the space is super small. It's very hard to get right.
@@ATCA let’s see , I was talking with MB enclosures look at he’s vids on a single 8 sub hitting 130 DB
Definitely a vented box of some kind. Perhaps a folded horn or L-port. If the port is too long to fit inside the box, let it protrude on the outside.
if you built the box flipped you could have done a extended port covering that lip on the left side and just had the 3 subs flush on the right side.

normally general rule of thumb you want your face plate of your box to cap your top ...bottom .. and sides... makes for a much stronger box.....it says very detailed... but never says how you tunned the port due to a triangle in the rear and rectangle in the front.. also did not mention what you think the box is tuned to....
Actually, I did. Taking an inch off the top and adding to the bottom doesn't change the tuning.
@@ATCA interesting... how may square inches is the new port... didn't mention... how long is the port.. didn't mention... you said you shortened it... or how you calculated the port size with the triangle shape in the rear.... but I guess by taking one inch from the top... and adding it to the bottom makes all the other changes the same 🤣
@thomasstott527 port is 30 in2 from opening to the inside. It's whatever length the subbox said minus half the Kerf Radius. Thos box is 36hz wh3n built which I think is exactly what I modeled
What kind of car is that? Trunk doesn't look familiar.
