Hi David. Thanks for your extensive reply. Indeed there are 2 physical sizing variables: port and box volume. Unfortunately the 2 volumes directly interact, due to the port volume occupying more or less volume inside the box volume. Hence, the video method shows how to tweak the 2 variables to achieve the required tuning frequency. Quite often (specially in car builds) the sub box max volume is set by the available max external dimensions, so at least this guides the iteration process. Thanks How2everystep.com

Thanks. Good question - it comes down to what amp power you are running. Generally you size your amp to match the subs RMS power, so no risk of over powering your subwoofer.

Hi there. Generally you need a larger subwoofer box, and also a subwoofer with a lower frequency response. I am currently designing a subwoofer box for a 10 inch subwoofer (Dayton Audio UM10- 22) and the box tuning frequency is 22Hz with a F3 of 17Hz. Your 12 inch subwoofers would probably go even lower. In my experience the room gain adds SPL to that calculated for the subwoofer box, but does not alter the frequency response. Hope this helps? Thanks How2everystep.com

@How2EveryStep Thank you. I went with 2 separate boxes tuned at 21.5hz. They are 3.7 cubic foot each, and the in room response for them is an estimated F3 of 14-15Hz.

OK will do. This to me is going to be one of the more challenging parts of this learning experience. Im also going to have some trouble when it comes to the electrical side of things. I got all my tools and supplies "table saw, router, Jigsaw, circle saw, sander, Brad nailer, shop vac, circle jigs...", now it's working around my OCD and making it actually happen. I can't just be OK with simple. I want to incorporate the wheel well which used to hold the spare wheel and stock "bose" subwoofer. It currently has 2 XS super capacitors and 1 secondary w/ lc2i, my current setup is in a simple ported box that was prefab and most Def not the appropriate size for setup "DS18 x2 15" exl xx". I've been told that these subwoofers "HOOL15.4" work well in band pass or 4th order enclosures and wanted to get a second opinion on that option as well. I also want to explore my options for adding an attached section for some mid/high speakers. My amps are currently mounted to the back of my seats, despite my very clear request to not be mounted there. I would like to get some info on what methods work for building Amp racks. Is there someone that I could pay to design this more complicated setup for me? I'm confident in my ability to build it however I'm hesitant to put my math into action or just numbers in general.

This is DIY and will only cost the paint and some sandpaper, probably around 75£. The result is absolutely fine, and should they start to corrode in five years time, you do it all over again, only it'l be much easier the next time.

The one and only ticket for a good job is to separate the tires from the rim. Likewise the valve base and the weights. Then apply the paint to an area that is almost dust-free. The grass in your yard is tenthousands of light years away from being dust-free. And for the final clear coat, it's better to use a 2K clear coat and not a cheap rattle can from the hardware store. 2K clear coat is more resistant to impacts from stones and splinters. Everything you have done is a waste of material and time. Take your wheels to a professional. The fee will be higher, but the result will be much better.

Bit harsh really as you’ve said it’s a DIY job. That said, I’m preparing to do this as DIY at home. It’s only £5 a wheel to remove the tyres and as they’re shot anyway, it’s worth removing them. I have a air compressor so all the painting will be with a spray gun. Unfortunately 2k clearcoat is best so it’s so important for anyone doing this that they use an air fed respirator due to the health risks from isocyanate. I’ll be hiring a full face air fed respirator for £25 for a week. Wheel repair first then sit it out until spring for warmer weather.

I always size to the sub RMS or amp power, which ever is lower if you are on the limit of high air velocity causing chuffing... thanks How2everystep.com
Simple my arse! The crack may look better than unmatched paint. Now you gotta paint the entire living room, matching color and texture.
Indeed, you really should paint the whole wall if at risk of not getting a good colour match... thanks How2everystep.com
Countersand. Score. Secure. Prefill. Hi strength 90 til tacky. Embed tape in hot mud spiked with wood glue (concrete mud). Hot mud over that. Cold mud to float. Prime. Texture match. Prime. Paint match. What crack?
And how did it turn out? I must admit at about the half way stage I was thinking of abandoning the "design it all myself" approach and instead finding some free or paid plan for my subwoofer, though that restricts me quite a bit in terms of driver choice. In the UK there doesn't seem to be as much choice as in the US (most self build videos assume we have access to parts express!)
what if I want ultra low infrasonic bass? like a peak at 18hz? would I need a big box tuned super low? or multiple drivers? I have 2 12 inch drivers. How do I know how flat the in room response will be?
Hi there. Generally you need a larger subwoofer box, and also a subwoofer with a lower frequency response. I am currently designing a subwoofer box for a 10 inch subwoofer (Dayton Audio UM10- 22) and the box tuning frequency is 22Hz with a F3 of 17Hz. Your 12 inch subwoofers would probably go even lower. In my experience the room gain adds SPL to that calculated for the subwoofer box, but does not alter the frequency response. Hope this helps? Thanks How2everystep.com
@How2EveryStep Thank you. I went with 2 separate boxes tuned at 21.5hz. They are 3.7 cubic foot each, and the in room response for them is an estimated F3 of 14-15Hz. Only gonna put 80 watts to each of them. Not sure what amp I can use other than an amp from a polk psw10. They are dual 2 ohm subwoofers.
@@SkittlesScott good job - you should get a great bass sound and feel with that response! Keep me posted how it goes. The 10" dayton audio ultimax sub box I am building will be powered by a 500W RMS car amp, that is powered by a 500W pcu (to be able to run the 12v can amp with 240v mains). It was the cheapest method of big power output amp with build in high and low pass filters. Looking forward to powering it up soon! Thanks How2everystep.com

Was it really necessary to film pulling all 6 plugs out, I ended up falling asleep and never saw step 2
I'm having some issues. I'm building a box for an audi q7, DS18 Hooligan 15" (4ohm) single ported enclosure. Could you please help
Hi there. Sounds like a fun subwoofer project! What do you need help with? Thanks How2everystep.com
@@How2EveryStep I want to use the most space I can, I have alot of it. I have my entire third row and wheel well to build a box for a DS18 Hooligan 15" (HOOL15. 4). Every time I try to calculate specs I get a really small box that just seems way too small for the back of my suv. I'm not sure how I can stretch out the specs winsd spits out while keeping the same requirements for the sub/Amp combo
@@DoTheSchwoo first work out what volume you have in your boot. The put this volume into WinISD to see what impact it has on the frequency response curve. I would suggest having 2 project open so you can compare the original winISD proposal to the project with the bigger volume. You should see you can achieve a lower bass peak with the larger enclosure and port volume. Thanks How2everystep.com
OK will do. This to me is going to be one of the more challenging parts of this learning experience. Im also going to have some trouble when it comes to the electrical side of things. I got all my tools and supplies "table saw, router, Jigsaw, circle saw, sander, Brad nailer, shop vac, circle jigs...", now it's working around my OCD and making it actually happen. I can't just be OK with simple. I want to incorporate the wheel well which used to hold the spare wheel and stock "bose" subwoofer. It currently has 2 XS super capacitors and 1 secondary w/ lc2i, my current setup is in a simple ported box that was prefab and most Def not the appropriate size for setup "DS18 x2 15" exl xx". I've been told that these subwoofers "HOOL15.4" work well in band pass or 4th order enclosures and wanted to get a second opinion on that option as well. I also want to explore my options for adding an attached section for some mid/high speakers. My amps are currently mounted to the back of my seats, despite my very clear request to not be mounted there. I would like to get some info on what methods work for building Amp racks. Is there someone that I could pay to design this more complicated setup for me? I'm confident in my ability to build it however I'm hesitant to put my math into action or just numbers in general. My brain works creatively
No substitute for chemically stripping and sand blasting. It is the only way to remove all paint and rust.
Indeed. This is a diy wheel refurbishment method that people can do at home. It really did remove all the corrosion pitting and prep well for painting. Thanks How2everystep.com
@baldrickscunningplan6154 If you want to go down that road it would be best to have them blasted and powder coated, that's around 350£ + 100£ for taking the tyres off and put them back on and rebalance. This is DIY and will only cost the paint and some sandpaper, probably around 75£. The result is absolutely fine, and should they start to corrode in five years time, you do it all over again, only it'l be much easier the next time.
The one and only ticket for a good job is to separate the tires from the rim. Likewise the valve base and the weights. Then apply the paint to an area that is almost dust-free. The grass in your yard is tenthousands of light years away from being dust-free. And for the final clear coat, it's better to use a 2K clear coat and not a cheap rattle can from the hardware store. 2K clear coat is more resistant to impacts from stones and splinters. Everything you have done is a waste of material and time. Take your wheels to a professional. The fee will be higher, but the result will be much better.
This is a DIY wheel refurbishment guide for people who want to learn how to do the job themselves at home. Good shout on 2k lacquer which is meant to set really hard and be resistant to stone chips. Thanks How2everystep.com
Bit harsh really as you’ve said it’s a DIY job. That said, I’m preparing to do this as DIY at home. It’s only £5 a wheel to remove the tyres and as they’re shot anyway, it’s worth removing them. I have a air compressor so all the painting will be with a spray gun. Unfortunately 2k clearcoat is best so it’s so important for anyone doing this that they use an air fed respirator due to the health risks from isocyanate. I’ll be hiring a full face air fed respirator for £25 for a week. Wheel repair first then sit it out until spring for warmer weather.
How can you do that without a clean room or in lack of better a operating room
I don't understand why anyone doing extensive wheel refurbishment don't take off the tyres.Taking off the tyres before wire brushing,sanding and spraying the wheels a whole lot better.
I see your point. However, if your wheel beads are in good condition I.e. tyres not losing air then there is no need to refurb the entire wheel. Also keeping the tyres on keeps costs down. Thanks How2everystep.com
Because 98% of people don't have a tyre removal machine knocking around the house......😅
Your gonna damage edges like this
You're
No
Which chemical to use to treat hairline crack in roof
Do you mean on the ceiling? Inside. Thanks How2everystep.com
where can i buy the full repair kit
Hello. I got all the parts off ebay. Had to buy individually thought. Thanks How2everystep.com
great job!! think dark gun metal grey wouldhave looked better on the car tho lol 😉
Thanks. You might be right there. I do like gun metal grey 😀 thanks How2everystep.com
Very nicely done
Glad you liked the wheel refurbishment video. Thanks How2everystep.com
They quoted me £50 for one wheel refurbishment. As much as I'm tempted to do it myself, I can't imagine taking my car out of use for two days twice (do a pair of wheels at a time). Great video, though.
£50 per wheel is a good price. Good luck How2everystep.com
Yeah Thats a great price, i was quoted around 600 for mine
Looks great, but don't think I've got 3 days spare to paint wheels 🤔
It took 1 hour per wheel and these were multispoke alloys that needed a lot of work. I would recommend doing the whole set of wheels at one. It makes the refurb quicker overall... thanks How2everystep.com
@@How2EveryStep OK. I thought you said you had to leave for 24 hours after each coat?
@@bonhoff67 yer I leave 24 hours between coats. So the hour per wheel is spread over a few days... thanks How2everystep.com
Group delay doesn't matter for bass outside of very specific situations. Group delay at 33 hz has no audible effect. It should be the least of your worries.
I agree group delay for 33hz is not such an issue as that frequency is not audible. However the frequencies close above the peak ie 60hz are audible so group delay is a consideration. Thanks How2everystep.com
Above 60 hz shouldn’t even be played by subwoofer Even my 13 cm b&w cm1’s have a -3db at 55 hz…
Once you’ve done the fine filler, should you lightly sand it again before painting to make sure it’s really smooth or is that not necessary because of the fine filler?
You can sand flat if the filler raises about the wall surface. I try to fill and scrape flush to avoid sanding. I find this is quicker... thanks How2everystep.com
