Great video Mark, never heard anyone bring up round port bracing before. Good stuff. Anyone wanting to take their build skills to the next level but don't have the cash to get a router and router table? You can do all the cuts shown with a straight bit, round over bit, a cheap palm router, a home made router circle jig (you can find plans online), a wood clamp & a couple screws. Draw out lines for holes and radii. Clamp scrap board behind cut area to prevent blowout. Set up circle jig for the o.d. of the tube use straight bit cut to depth. Reset jig for i.d. of tube and counter sink 2 screws through the center piece your about to cut out into the scrap wood behind it. Cut out center with router ( this may take several passes lowering the bit slowly each pass). For the port brace cut the circle first then the radius so you'll have better options for securing your work piece. Follow up with round over bit. Start with less then $50 in harbor freight tools, upgrade to better when you can.
Hello Mark. I'm going fulltime with speaker system production at home. Just bought a router the other day & I needed the rabbit bit information/recommendation. I have picked up some vital tips from watching your channel over the years. Thank you!
I really appreciate your videos. I am a audio enthusiast, but on occasion a friend of two have asked me to build them a box. I usually Vinted style ports boxes or sealed rarely. Your videos are validated a lot of the techniques I use. It has also enlightening on many new ones. Thank you for your contribution to Car Audio and the RUclips Community!😊🙏🇺🇸
Tip: gang up two pieces of mdf with your templating tape and then jigsaw/route out your inner diameter holes at the same time. Saves you some time/steps, plus ensures that both your outside panel and inside brace have their holes perfectly aligned so there’s no stress on the glue joints. 👍🏻
You are awesome sir. I have always loved car audio, but the shops around me act like I don't know anything. The fraction of knowledge I have and your assistance I quit going to them and started using your recommendations. I will build an extremely awesome system for my 1972 chevy caprice restoration.
I have always enjoyed all of your videos, I have learned so much. Your knowledge, attention to details and how clear your explanations are, makes learning so easy. You never come off as arrogant and have a great sense of humor. I completely agree with Rodman8500, you are the “GOAT”!
Grab a DATS program from Parts Express. Run the DATS program on your subwoofer, to get the TS Paramters. Use the TS Specs, to determine your proper tuning frequency for your specific application.

@@CarAudioFabrication hey I had a quick question for you. I'm running a single 12" infinity kappa 1200w in a vented ported box. The box isn't big enough for the subwoofer so I'm having my local shop build one to spec. I'm running a SKAR amp at 600 watts at 2ohms. My question is before I give the green light which hits better a TUBED flared port or a vented port box? My local shop said a TUBED flare hits better but I don't know. Thank you I love the channel because of you I bought and running the LC2i in my lexus so I no longer lose out on bass when turned up past 45 thanks again 😊
I have 90s 12" subwoofers giants speakers box sound amazing but the box is square.need an upgrade for my 2014 VW passat and you are the guy that is going to help me build the perfect passatbox
You should get a CNC machine. I’ve been into audio and just got a shapeoko 4 xxl and it allows me to make some pretty complex enclosures. Basically you cut 3/4” material and cut a bunch of “rings” that have the same cross sectional shape of your enclosure. Make a bunch of them than stack them up and glue em together. This allows you to make your walls as thick as you want, and you can design 3 or 4 of the rings to incorporate complex bracing that will keep your enclosure as dead as possible.
As always, thank you for your dedication to mastering car audio and putting out great content for people like myself to learn different techniques and ideas! Maybe a video on determining round port sizes next
I thank you sir for this video it really helped me a lot I am in the process of building a soapbox and this is exactly the style of port I wanted to use and I had a few questions that you perfectly answered!!
how do you decide where and how to place the port or is all preference? And on another note.. thanks for doing all these videos. Man your truly a lifesaver. I had bought 3 12's a few amps and head units from a buddy. Got it home and realized I had no idea what to do with it. Found your videos now I'm hooked . When I get this box finished I'm going send you a video. You helped me get it done. Thanks
This is awesome. Anyway you can do a video on how to design an aero port. Like all the calculations and building it from scratch and flaring ends? Would really be interested in that. Keep up the awesome work.
I love round ports! Great design, Mark. Would you go as far as wrapping the PVC in some sound deadening material to add mass? Just curious what you think about that - I would have to ponder it if I were building this enclosure.
A trick I do is make a wooden ring that you afix to the box wall for the port to slide into. If you make two, and sandwich them together, make the ID slightly bigger than the OD of the pipe on one ring, and match the OD on the other, when you afix the stacked rings to the box wall, a recess is created for the carpet, vinyl or leather to go into as the covering goes into the radiused port. Cover it, and then when you slide the port in, it will clamp the covering and give you perfect edge from covering to port, and will hold the covering and make sure it will not come loose.
I always like your videos. Getting ready for my first Aero port build myself. Wish you could do a video on Tunning the port. That where I am kind of stuck at. The only pie I know is in the kitchen. Thanks
I've always done this with two pieces of wood as I still don't own circle guides. First is cut to outside diameter as close as possible with jigsaw, second is ruff cut within the inside diameter, glue together, glue onto tube, then use tube to flush cut to inside diameter and then use radius bit too round ends. I always try to design the box so the tube ends at a window brace which is much easier when doing stage and club systems.
Oh, I had one other question if you have time. Do you have a video on port/vent and cone clearance? Like the distance between the inside wall of your trunk from your port opening. Because I only have about 2 inches clearance from my port to the trunk wall and maybe 3 inches from my sub face to the back of the seat. Am i losing sound/bass quality? I cant seem to find any videos on this. Thanks
You can even use regular ¼ inch wall thickness PVC and round over just the pipe. I used the pipe and put it on the board where I want it to be and trace the outside of the pipe, and than cut a square piece of wood and apply it to give the port hole a double baffle so the tube is very snug, so snug in fact I wound need to take scrap piece of wood to put over the tube to beat it down in and make flush with the wall. And in the inside ill take wood glue and make a bead around the port to give it an air tight seal after I round over the pipe wall. It works great with no port noise.
I’m in the research phase of my first box, I’m thinking of using a toolbox style latch to secure my sub because I do have to use my space occasionally, any reason why I shouldn’t. I’ve enjoyed your vids, very informative.
You can intentionally raise the round over bit more out of the table. This will leave a hard edge. You can use that edge to precisely trim the carpet and paint the smooth transition
2 sundown x18v3....14 cubic feet box at 32 hertz.....can I use three 6 inch ports at 11.56 inches to reduce port displacement.....or do I need four 6 inch ports at 16.87
I’m learning a lot from you Mark, my question is how would you wrap the material around the port? How far would you bring the carpet into the port? Thank you
Hi sir. May I know the details of your all equipment for trimmer and also the brand. Thanks. I amaze your set up. Iw ant that kind of set up. Please help me to get that
I have a question. are 7X10's designed to be in free air? or would they perform better in enclosures? I don't have any room for subs all I can run is a 4 channel 60W amp 2 7X10's in the rear and a set of 3 way coax with crossovers in the front. would I get better bass in a enclosure? thx mate
Sir what tuning hz of that box? I mean the port length? Coz mine is 31hz but only 9.80” but yours too long? My box 26.5x13.5x17” is it correct 31hz@9.80” port lenght? I am curious.

Grab a DATS program from Parts Express. Run the DATS program on your subwoofer, to get the TS Paramters. Use the TS Specs, to determine your proper tuning frequency for your specific application.
That is the first time I've seen that color of pvc! Thought you painted it...but I was wrong. The router would have made that evident.

So tempted to give making a sub box a go now
Hey, I was literally thinking about this yesterday! I really should get one of them routers
Nice video since i am planing out a new ported box for my JL audio 13W3V3-4👍
I've always done this with two pieces of wood as I still don't own circle guides. First is cut to outside diameter as close as possible with jigsaw, second is ruff cut within the inside diameter, glue together, glue onto tube, then use tube to flush cut to inside diameter and then use radius bit too round ends.

I’d love to see him build a blow through for my avalanche midgate. It would be so beautiful
How would you go about the carpeting around the port perimeter?
Go a little deeper with the roundover. It will leave a perfect crisp line to run your blade in to trim.
That sounds about right. Has anyone ever told you that you are a very smart person? What's your IQ?
Oh, I had one other question if you have time. Do you have a video on port/vent and cone clearance? Like the distance between the inside wall of your trunk from your port opening. Because I only have about 2 inches clearance from my port to the trunk wall and maybe 3 inches from my sub face to the back of the seat. Am i losing sound/bass quality? I cant seem to find any videos on this. Thanks
I absolutely love it man! Knowledge is power. Thank you
How would you calculate the flare of the port when building it like the video
Just like usual but account for port end correction.
Beautiful man! That looks like perfection. 👍🏻
Very inspiring. I want to be able to go the next level. I will be looking at router tables. I'll check out your links.

Does this effectively increase he length of he port or is it accounted for in port length ?
Badass advice, keep up the good work. 👍
Excellent video, thanks for the great information as always.
Thanks for watching!
Looks good Mark
Nice job on this. Thank you.
Good idea! Next, show us how you would carpet the exposed flare. Looks like it would be tough without some sort of edge to run a cut around
You can intentionally raise the round over bit more out of the table. This will leave a hard edge. You can use that edge to precisely trim the carpet and paint the smooth transition
Maybe a slightly larger diameter grove to tuck the material, and then paint the port ...
Maybe an abs trim ring as a transition...
Sky is the limit.
