Tapped horn / Folded horn subwoofer box build

[samLIPS66]

close your eyes and listen to the first 17 seconds lol

[dimensionsofearth]

Very nice, I have yet to build any sort of horn subwoofers and I am really looking forward to it, that is one beautiful build man keep up the good work.

[DJHiggumzDubstep]

now i know tapped horns arent like this, but if the driver was in a sealed chamber you could get more sound out of it, because it would "tame" the cone movement. just a thought

[vegmatic1966]

@DJHiggumzDubstep Sealed cabs have the air spring effect that can tame cone movement, however, cone movement in a horn is smaller around the tuned frequency and that can mean less distortion. Horns and ported speakers should not be driven very hard below tuned F to prevent potential damage to the driver.

[DJHiggumzDubstep]

@vegmatic1966 yep that makes sense, i have it highpassed at 45 hz (t39 dj bass horn)

[moofushu]

I was wondering if you think it would sound better with a port instead of an opening right behind the speaker?

Dieses Prdukt ist sehr gut habe den subwoofer im eigenen Party-bauwagen und ich muss sagen ich bin überrascht. Wenn ich diesen Subwoofer richtig aufdrehe vibriert der boden.

how do you design folded horn subwoofers?

[vegmatic1966]

@wow1022 One design software is horn response. For a beginner, it is best to emulate others designs.

[kemurcho0]

how can i make this horn with lower setup? I make one with 6.5" driver, but it have power above 70hz... What must i do? Smaller hole by woofer magnet or wath?

[vegmatic1966]

@kemurcho0 A shorter path would mean higher frequency. You have to know and use the Horn Response software to do this right.

[MrPulamea]

Hi , great job with it . Did you get the better driver ? how does it sound ? . I got 2 Voigt tapered pipes, 6.5 inch drivers. I want to build a tapped horn for my pc, the driver I will be using will be around 4 or 5 inch, I have no idea how to use that software you mentioned, could you give me some dimensions for them ?

[vegmatic1966]

@MrPulamea I got the driver and it sounds great. See my newer videos of it.

You have to have the T/S parameters of the drivers to even start. Sign up on DIYaudio. Lots of helpful people there. Hornresponse is complicated for the new user and you have to know some things about acoustics.

[SpeakerFreak95]

@vegmatic1966 do you want to sell the realistic woofer?

[vegmatic1966]

@SpeakerFreak95 I no longer have it. Thanks anyway.

[1BlubeTube]

Why plywood?

[vegmatic1966]

@1BlubeTube Why not? MDF is a good choice too.

[scottjinx]

How does the small perspex model sound?

[vegmatic1966]

@scottjinx Not that good for a sub. It's small size means it is tuned higher (120Hz). It is just for demonstration.

[scottjinx]

@vegmatic1966 Hi, yeh i built one anyways for a 4 inch woofer just for a bit of fun for a small computer setup, i didn't think it would work but it actually performs pretty well, loud & clean bass for a 4 inch & your right it is loudest around 100 - 120 hz but seems to do well enough with the low bass notes & drums too hey, cheerz :)

[ineedmorebassx10]

Click " CC " button and then "Transcribed Audio " Then read what it says, really funny! " Howard you did Dick "

[l337pwnage]

I used to have a 12" Rat Shack woofer like that. I used it in a friends car. Performed quite well. The speaker ended up moving so much that it eventually broke off one of the flexible wires that connects the cone to the terminals.

Later on I started using MCM Electronics woofers instead for my projects.

[vegmatic1966]

@l337pwnage Mine suffered foam rot of the surround. The parameters show it is best used in a sealed box.

[TheElectronicaman]

@vegmatic1966 what would a 10hz tapped horn with 2 18s in it sound like?

[vegmatic1966]

@TheElectronicaman It would make the walls breath, but would not sound like much because human hearing is weak at 10Hz. makes little sense to tune so low. 30Hz for music and 25 to 20Hz for home theater is as low as I'd go.

[Lightninglad999]

LMAO!!! imagine if someone blind was watching this from 0:00 to 0:14 they be like o.O

[rodneyk]

@Lightninglad999 did you think before you posted?

[rw5791]

hey,I built this same speaker a few years ago.Got the design from some australian guy.It's good for the home theatre or even high end stereo music systems.

[gychang00]

thanks great video, want to build one, is there how to someplace ?

[gychang00]

thanks for excellent electronic-audio videos, very useful for me.

[azfluffy]

that what she said

[mikehoncho119]

I like the vid an idea! Great post!

Coming from the SPL world... I bet you would get better efficiency if you wrapped around again past the port. The drivers rear fire would have better loading an in effect help with control on the speakers motor.. Just Food for thought, could be wrong.. but its what I've noticed

[dan0987654321]

can i get some plans for this project? im interested in building my own yet know nothing about the math part of horn subwoofers

[stolemycuecumber]

i have one in my car ppl cnt beleive its only one 10" sub pushin only 200 watts. it out does 2 12s easy

[kirren97]

well, PUTT SOME FUCKING MUSIC ON!! :@

[ExpertOfSound]

This is a great design!

Thanks for the video, I think I am going to try to make one of these too :)

[lrd9999]

The 30Hz peak is probably the point at which the the phase shift over the length of the horn is 180 degrees, so that the sound from the back of the woofer is in phase with it. Ported enclosures almost always have a "comb filter" effect, I doubt that a better driver will affect that problem much.

[lrd9999]

Properly tuned passive radiators offer one way around the "comb filter" problem, but it would take a lot of engineering to get that right.

[MrDjmcloud]

nice nice how do you think a 12 inch spl based woofer would work on this set up with about 700 watt rms dual vc that being from the sub and a 400 watt amp bridged? i got a 12 im diein to get more power out of

[elvislad]

Yeo great viid,I to have always wanted to build one of these and now Im gonna!!!now just need a bigger room...

[MrSPLman]

cool vid !

[bvagansfan]

only 3/4 of a watt! wow my 120 watt sub doesnt even produce that much bass! ive found my next project thank you and awesome video

[classic65stang]

Awesome stuff, I've always wanted to build one, this inspired me to build one. The mic on your cam was great. sounded really nice going through my marantz and cornwalls

[Elnufo]

very cool demonstration! did you calculate your cab for that specific speaker that you are using, or is it just "any" TH design that you threw a random speaker into?

[vegmatic1966]

I just used an old speaker. I have since replaced it with a well matched driver. It now has a flatter response and deeper extension into the 20Hz range. I'm completely satisfied now.

[otyiromeo]

@vegmatic1966

[splaudio1]

not bad for 3/4 of a watt but where can i find that software download

[tudajfor]

very cool stuff!

I got the feeling that the floor beneath my legs was vibrating, and I used my headphones :)

Sennheiser HD555!

Great work man ;)

[vegmatic1966]

Thanks! I can't wait until I can get a better driver for it. I have a pair of HD530s, but the cord is bad. I haven't been able to use them in years.
