700 lb DIY Speakers 

It was because of the drugs I swear

Thank you for the kind words

This guy gets it.

the intro is the speakers, same with the nas bit at the end, but the classical montage music is dubbed.

DiyItYourselfYourself thanks for the info happy new year!!

I have to test out the highs somehow

Thanks boss

They're a little small

@@sugastuff8838 Yeah, my bong's bigger than those things!

youre the mqan!

What a sarcastic douche bag. And what high end product / craftsmanship do you bring to the table?

+Vlad Grigorian thanks for the kind words!

I have so many questions. 1) How long did it take you - from building a spec to completion? 2) How much did the project cost you, all in? 3) How do you crossover the speakers - an external crossover, or did you buy a built in crossover or made one from scratch? 4) How do they sound? 5) If you had to do this all over again, what would you have done differently? Overall, I can only imagine how great it feels to make your own speakers. How much fun that is, I mean. I wish I was as good with all the tools. BTW, did you have them already or did you have to rent/buy them?

Vlad Grigorian I will make a follow up video shortly on the speakers replying to this comment and some others. Those are great questions

Outstanding, thanks

thanks m8!

Man its too low. The walls rattle like crazy.

mdf because it doesnt have voids in the wood like plywood.

Mdf is at all much better just knock it you can hear and feel the difference

birch plywood have no voids, ok it cost nearly the double.

Plywood is good enough, stronger then mdf but maybe more resonant.

@@lucabergantino6894 Birch Ply is indeed double the price, but its also half the weight, and non-toxic.

David A Craven I'm glad you like them!

Haha, that's what building your own speakers does to you. If I ever start talking about sound systems I just start rambling

Derik Henderson cool story bro, tell it again.

+clemmtec thanks a ton for the kind words

its an active crossover. the crossover is a dbx 234 i think. the tweeter is an Aurum Cantus AST2560 Aero Striction Tweeter. All the drivers are suspended from the base to isolate vibrations. i honestly couldn't think of a way of mounting the tweeter, but this method gave the best imaging as you said and made it easier for dipole sound pattern.

Nice! Thanks... I'm gonna have to try something like this sometime for myself!

FishFish1995 i got em i a new room now haha. Much better cable management now. Cheers

I had to pan fast so you cant see the shotty craftmanship

terry tate the low end is driven by a 500 watt per channel plate amplifier, the miss are driven by a 300 watt per channel plate amplifier and so are the highs. There are 2 channels (one for each speaker) which puts total power handling at 2200 watts. Of course those stats are based on the manufacturer data so it's safe to presume that the actual output is less. Also the highs never draw nearly that much power. I have the boards being powered off of a 1500 watt rectifier board and that thing hardly struggles so it's safe to assume that the power never gets close to that. Still though every tier of each tower has a sensitivity of 96 db per watt so these things really give the walls a run for their money. The whole amp system is made from premade boards except for the transformer which I found to be half the price to make myself.

there are no wooden staffs. they dont touch the top of the base cabinet. thanks for the advice.

everyday is a party in my house

the cables isolate the mid box from the low box. its kind of like a suspension bridge. i also thought it would look cool on the finished product.

It does look cool though!

Chris Woods

i have B&W speakers and they actually sell speaker spikes that achieve the same goal.. looks like spikes that go on the bottom of the speakers

Chris Woods I know this isn't why he has the cables but I have cables similarly on my system, and that is because they aren't long enough to be hidden behind my desk, will say though, it looks really cool like that but I have a few different types so not so much for me unfortunately

Hard to say. More than id like to admit. So many hours of sanding.

Torkel Werge I'm not really sure if the cables were worth it. I suspect the effect on sound would be negligible. The tweeter up top however is very cool. It males the room sound like a big theater or hall. If you close your eyes you can get a sense for the size of the speakers. The best way to describe the sound is big and open.

@@sugastuff8838 Hi i find very interesting the tweeter placement ... unusual but if you get what you mention i am sold. May i ask 1) which drivers have you used for this very impressive project ? 2) which cut frequencies between the 3 sections ? i guess the drivers are connected in series ? 3) which sensitivity ? 4) do you get some depth of soundstage ? Thanks a lot, gino

Hello big boy, i appreciate your concern about my safety! While the structural integrity is certainly not up to par, i did remember to remove any remants of c4 that the welding process left behind, so i should be safe from shrapnel. Yours truly 69

They appear to have worked out very well, Is this the first pair you have built.

thars be the tweeters and the suspension system for said tweeters

girlfriend the perfect system.

+Kevin Swanepoel thats exactly what we have in the new setup haha

jibba02 I'm nothing without my welding crocs

Your speakers look nice. Check out these nice looking DIY speakers www.audioasylum.com/audio/speakers/messages/35/356566.html

We want speaker schematics.

I have plenty of suggestions for you. If you can take constructive criticism, here goes: Firstly, I like the fact that you are building, not buying. And you have to start somewhere, so well done with the correct mental attitude. Content wise, the speakers look like steam-punk at best. There are many mistakes and errors, bud. You don't know how to cut, glue, clamp or join properly. And your table saw technique will soon see you parting ways with a finger or two. Probably the second worst use of a table saw I have ever seen. At least you seem to be wearing safety glasses, so that's a plus. Regarding choice of materials, rather use MDF or particle board for cabinet construction. Plywood is not a great material for speaker boxes, because it often has voids between layers, and it flexes too much. These two issues can lead to resonant panels. Any joint that is not structurally sound will also resonate. As a beginner, you should focus on simple box designs that are within your skill set and your tool set. Use butt joints with interior battens that will both strengthen and seal your box. Finish exteriors with bondo rubbed down properly to conceal lines, and matt grey, or black paint to finish. Or a textured paint like fleckstone or truck bin liner instead of the bondo and matt paint. Use a router to ad half round profiles to edges. Regarding the mid-range enclosure. From your video, it appears that your mid drivers are sealed at the back. So no enclosure needed. Regarding the steel framework: Totally unnecessary, and badly welded. Why bother with that crap of suspending mids and a tweeter? Absolute nonsense, mate. If there is a reason behind it that anyone could hear, all speakers would be made that way. Forget esoteric, audiofool nonsense. Concentrate on a well made box (use a driver with known T/S parameters) , with ONE full range driver, and ONE tweeter. 12 or 24 dB/octave active filter, decent quality amp modules. You will be amazed at how good it will sound. If you want me to give feedback on your video, let me know.

I sincerely appreciate the criticism. You are absolutely correct, I do not know what i am doing. This was my first real woodworking experience. I completely disagree with sticking to simple projects however, I feel that attempting projects totally outside of my skill set is the best way to learn faster. MDF is definitely easier to work with. However i have also read on multiple sources that MDF makes the sound dull and removes musicality. I have read that dense plywoods sound the best as box materials. Unfortunately dense plywoods were out of my price range so i went with spruce. The reason all speaker are not made that way is because its a pain in the ass to do and expensive. However if you look at many expensive speakers they have the lows mids and highs on separate baffles. Im not sure if it makes a difference but i thought it would look cool and increased the scope of the project. Focusing on designs in my tool set is some great advice hah. The angles were so inaccurate i spent too many hours sanding. The mids werent close backed, however i did design the box to be way to big (i designed the mid box like a woofer box) because of lack of experience. Any woodworking feedback i would appreciate however i will continue to attempt difficult projects.

As someone who is also in the DIY speaker hobby, I can say you have much to learn. We all have to start somewhere, and you certainly don't seem afraid to jump right in and get your hands dirty, so kudos to you for that. But consider reading through some of this before you decide to tackle another project, you will be glad you did. techtalk.parts-express.com/forum/tech-talk-forum/38661-the-speaker-building-bible

socksumi If I opened up the door to the hallway, the room sort of acted as a second order bass reflex cabinet with really weird resonances.

+Karol land I agree with you completely. It's tough after enough hours of sanding

I know well what ur saying..im building cabs for living..and trust me...nothing is more rewarding then detailed labour..annyways...respect for taking big project and im sure ull get it shining next time..

Eventually that's where they'll end up

@@sugastuff8838 nice speakers tho

+Selendrake74 I'd say it about half n half. It's really good (Not quite audiophile) but the sound quality stays the same up to an unreasonable volume

Marcelo at the time I was 20

Wow!!! 👏👏👏

Thats the only way to do it

maybe someday

Too late, I've already lost 9 of my fingers

@@sugastuff8838 well ... you can still pick your nose. That's saying a lot.

take notes dan this guy knows what's up

i wanted to test out the 20khz sound zone

check out Allan Taylor Colour to the Moon and stop listening to garbage XD

Fuskers I have it set up so that you can only listen to JB. It was a bit of a design flaw (sometimes I feel like listening to fetty wapp), so I'll have to change it on the next system.

ok justin beiber is better then fetty wapp any day at least one of the has talent Haha

kwazykilla87 debatable

+hahasimpsons this was my first build. Why does everyone expect perfect build quality?

DiyItYourselfYourself reading between the lines i implied that it was good effort and your next build should present much better results. You incorporated many interesting design elements which were unique. Live and learn. Don't just repeat and expect differing results.

hahasimpsons my apologies. Thanks for the advice.

You should do a video describing why you built it like you did, for example why you used resonant materials to build the suspension system and what effect you intended for them to have. Also which Behringer amp and processor you used and how you like them. I have a a Yamaha RX v667 feeding a Behringer Ultra DI pro and Feedback destroyer pro, going to 4 Altec Lansing 9444A and 1 Behringer ep4000 amps, but would like to get 5 of the iNuke 3000 dsp's and a 1200 for the subs. Fun stuff to play with.

Yeah they didn't come out as i hoped they would. Next time i will add more acting just for you!
