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.
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. 👍🏻
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 UA-cam Community!😊🙏🇺🇸
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 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”!
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.

@@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 😊
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.
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 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
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 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!!
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.
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.
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 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 like this version of rounded of/flared ports over the plastic versions for permanent installation, but for quick swapping and without alot of woodwork i would just buy a simple plastic pvc flared flange with screw holes for mounting, and a flared pvc flange for the other end, but still use your method for holding the port and round of that wood with the pvc port flange flush mounted with the wood surface for good airflow and less portnoise because of turbulance
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.
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
my first port was a cut up plastic beer bottle, one song sounded good but then the rest sounded like i completely removed the sub lmao. i've always wondered how 110mm toilet pipes would work as a port
@@CarAudioFabrication Typically, round ports offer the flexibility of adjustment, but (while harder to do) slotted ports can have that versatility as well. Though, aside from that, it'd be nice to hear the rational differences behind "what port type to choose", and possibly even hearing the difference between one of each type (tuned to the same frequency), for comparison...
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
Hoping to see a finished video on this port build. Would like to see it performing in the car as well. Also, where do you order your vinyl from? The local company I get mine from is not carrying the 4 way stretch anymore.
Mark, I've been watching you videos recently and I have a question. First off gotta give a disclaimer, I have been away from car audio for about 15 years. When I was building my stuff for my cars (I was a budget guy) I used capacitors to help with electrical current draw on my electrical system. I see that you've said nothing about capacitors, are they not a thing anymore?
I have a question, it’s probably pretty simple, I have upgraded door speakers. That have a rms rating way higher then what the receiver puts out however it still sounds good. Now here’s the question, if I was to get a amp that correctly brings the speakers to proper rms ratings would it make it sound any better, or would it just bring the sound levels up without distortion or would it do a little bit of both?
I always think you are the "GOAT " of car audio fabrication ,hands down the best ideas and content. keep it up MARK!
You are teaching this generation a wealth of knowledge. The stuff we learned from our mistakes. Keep it up nice job
Great video Mark, never heard anyone bring up round port bracing before. Good stuff.

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.

Definitely more clean than the way I do mine. Now that I know better I will do better, thank you sir for the great video.

Great stuff mark.
Ok yhe outer port lloked good but whe u did the inner end man that was really beautiful most excellent detail
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.
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.
Hey, I was literally thinking about this yesterday! I really should get one of them routers
That looks really good! 👌
Just did this for a box with two 8” subs. 2 cubes tuned at 32 hz using 4” port.
How would you calculate the flare of the port when building it like the video
Just like usual but account for port end correction.
That's a really good looking Port!
If only all the awesome kit wasn’t so expensive, I would kit out the garage nicely 😅
