I know this is an old video but, typically with a "sub-woofer" passive your dealing with a passive radiator greater then the bass driver. I/E bigger diameter and/ or longer excursion passive. Also the enclosure is not properly done. The sound deadener just puts a band-aid on a persistent problem, the enclosure should be thicker or have internal supports. Deadener is better suited for vehicles to reduce resonance, doesn't work well in an enclosure since it isn't as ridgid as wood and isn't as absorbing as insulation. Proper bracing, better passive, you should see much better results, also make sure to have the right amount of weight(s) on the passive. You can add or take away washers to the passive radiator to "tune" the output. A thin layer of batting or insulation around the inside should bring that resonance down significantly.

I dig it! Enclosure building can be taxing and rewarding all in one, but I love doing it even when I don’t get the results I expected.

This video should be titled : How to make a subwoofer box.

You always have the nugget I need ❤️

Hey, I am just another DIY audio guy and I share the same philosophy as you. I picked up this hobby for the fun of it and for the reward you get on a successful built.

this is great, your enthusiasm to learn is helping me learn from you

Love what you are doing!! It's been a minute since I built any speakers , but I definitely appreciate the craft! Done lots of sealed, ported, 4th order, 7th order crazy stuff in the past, for car and home and am starting to think about upgrading my home theater from factory soundbar and 5.5" powered "sub". You are giving me some inspiration! Thanks!

Awesome job. The speaker turned out nice and I love that you got the wood for free. Keep up the good work!

Nice Work!!👍👍

I subscribed! Your videos are fun to watch. The pr projects I’ve tried in the past I used a subwoofer and a larger radiator in a smaller size enclosure. Seemed to work decent, keep up the great work

keep them coming.

Love the videos, and sharing as much as possible! Btw love the Orange Shirt!

Just ran across your channel/vids. Haven't fooled with audio much in the last 20-25 years. Getting back into it just out of curiosity. Building a sub setup for my SXS. Researching sealed v ported v radiator. Trying to do something different. Building the most for the least has always been my MO. It's fun getting back into it. Keep the vids coming.

Great video i enjoy the content. I've been building subwoofers and enclosures as a hobby since high-school. Keep the great content coming. Definitely "sub"ed to your channel. Pun totally intended. My most recent fun project was building my first 1:1 ratio 4th order enclosure using an old 90's earthquake audio 18 i picked up for cheap. The best part is the looks on listeners faces when i tell them I'm only powering it with 40 watts. It has a pretty impressive bandwidth. It peaks around 60hz on the sealed side and the ported side is tuned to 32hz. It's comfortable playing in the 20hz range as well. Can't wait to see more content or your channel.

Cool dude 😎

I know this is old so im sure he had learned now but i always go with 2 PR of the same size as the active driver. Because I learned the with just one PR its so easy to over load it and reach its xmax and push to distortion. So i cut a new hole in the back of my box behind the first PR and man it was a big difference. It played lower tones louder and really took most of the active drivers cone movement away at the frequency's I tuned the PRs for. (32hz) Its 1, 10 inch mid range driver i made as floor standing speakers so 2 boxes the has 1, 10 inch mid bass driver, 1, 6.5 inch midrange driver, 2, 4 inch tweeters and 2, 10inch PRs in each box. They sound like they have subwoofers built in lol perfect for movies and games. Music needs a little help from a real sub but they still kick

nice idea orange shirt

I love this.... I've always thought it would be cool to do 12 in home theater end tables. Granted I'm not sure you could put anything on top of it 😁

You did an amazing job. 👏👏👏👏 I want to build a 14 inch square box with a 12 inch sub llus 2 12" passive radiators. That is the idea but I might have to change a few things. The hope is to get low to 20hz. I will be using a SVS 400 RMS amplifier.

Good

Awesome project! Go HF tools!

Nice work, I need a router and a table saw before I can start doing a serious build like this. I’m thinking about using a passive radiator.

Very nice videos So you think that putting the sound deadening material inside the enclosure cause any kind of change in the tuning frequency of the enclosure?

As curious to this since I just found this channel, will you still be posting more content?

If you checked out a pr from psi you would like them. They make they're subs and pr's from the same baskets and cones

Where you found the bass radiators?! I can't find in Greece!..

I was wondering if i should build a subwoofer enclosure with a passive radiator, but i`m not sure if i should go bassreflex instead after watching lot`s of videos on youtube. I really don`t know if a passive radiator or bassreflex will go deepest in bassreproduction?

hi there, i', trying to build a subwoofer which consist of one orion hcca 15" as active speaker and two DD 500series 15" subs as passive radiators, it is my first time trying this so i would kindly ask all af you if you can recommend me how many liters should the box be? internal i mean.

Olá amigo,você pode ajudar com um projeto,tenho um woffer de 6.5 polegadas de 180w com o fs de 44 hetz,um par de Tweeter domo de seda e um radiador passivo de 6.5 polegadas também, qual litragem você me indica pra esse projeto?

How long you been doing it

I love you're videos and the inspiration you make for people... Check out my amateur videos of my passive radiator subs. They gives a punchy bass all the way down to 20Hz. The small subwoofer I use in my car cost me about 25dollars to make, because the Rockford punch driver needed a bit glue to work properly. The passive radiator was a completely blown sunfire hrs-10 driver I got for free. And the box was also a blown subwoofer with a 8" woofer. The Rockford punch driver is rated to 250w rms, but it makes an impressive spl with the passive radiator well below 25Hz. To make the radiator I cut off the magnet, made a flat round aluminium membrane. Filled the cavity between the 2 membranes with building foam. And added about 260grams of weight in the voicecoil with a chemical concrete.

This part 1 & 2 videos shoulder

Why is your eye red,done some fighting?😁

I’ve got a Memphis Mojo 8 I’ll loan for a video. 1000 RMS on an 8! Lol
