Out of interest did you use a plasticiser agent and vibrate the shuttering after pouring the concrete? Wondering if the voids are inevitable or if I can avoid them. 🤔
Has someone tried AAC ( AUTOCLAVED AERATED CONCRETE) for bass boxes!
ХУЕТА КАЗАНСКАЯ!
Great job... nice
Making a concrete cabinet for speakers that don't produce much low end bass seems a bit over kill... The whole idea is to reduce cabinet resonance but it's hardly producing any with that small driver.... A beefy over engineered small woofer/ tweeter combination would of been better IMO 🙂
Would have been nice to have some details of what you were doing, I would also recommend some black screws so you cant see them. If you do want to see them, some shiny nickel plated ones or brass ones
I am building concrete speakers with the same drivers but have them ported. Using a cylindrical mold and cast the front separately. I have some ideas how to treat the concrete when finished but curious what you have been using. I have been hinted to use soluble glass. I can say that I am building a 3 litre box with approx 20 mm walls and have been using about 10 kg och (mixed) cement. Reinforcing with glass wool. Also I used a dash of acetone to get a hole in the filling and from there carve out the rest with a sharp knife.
Finally a build with a sound demo!! Great build!!!
Awesome way to build it
How many bags of concrete did you use for this?
Im very sorry, but I havent written down how much I used :( One speaker casing weighs around 7kg/15lbs, maybe you can calculate it from that!
I never saw you add binding posts, nor do I see wires going to the speakers at the end of the video.
That's what the straws in the concrete casing are for :) I didnt want to drill a hole in the finished casing, so I put the straws in and pulled them out. Then I attached some binding posts, similar to that: www.amazon.de/Hifi-Lab-Lautsprecher-Bananen-Buchse-Anschlussklemmen-vergoldet-transparent/dp/B01FQZTL1M/ref=sr_1_16?__mk_de_DE=%C3%85M%C3%85%C5%BD%C3%95%C3%91&dchild=1&keywords=lautsprecher+buchse&qid=1603619864&sr=8-16 For the sound test clip at the end, I purposefully arranged the speakers, cables and amp so that you cant see them, because I thought it looked better.
How did you give the border edges for the front baffle to fit on them? So curious
Ask a skilled carpenter/mason. He knows how it is done @YashasvSaluja.
Hey, sorry for the late answer! The inner part of the concrete form had exactly the same measurements as the wodden front baffle :) So naturally it fit perfectly. Was that what you meant?
Cool, but you forgot to port it.
Didnt forget, just didnt port it ;) With speakers this size, with already ignorable bass, you dont need to put a port in.
@@concreteeverything1605 You might be surprised at how much of a difference a port can make. It should extend how deep the driver can reproduce by quite a bit. If the bass is as bad as you suggest, and rolls off at say 125Hz, a port could bring that down to 85Hz as an example.
Nice build! Can we expect more Concrete projects / speakers builds?
Thank you! If I had the time and money, I would probably be building speakers all the time. But because I'm in college, I cant build regulary. So to answer your question: Yes! But I can't say when :)
You can used lightweight concrete (1600kg/m3) to lessen the weight..
Did you ponder adding a port for increased bass extension? I've never messed with speaker box software before.
I went with a sealed enclosure, because its my first concrete speaker designand I wanted to keep it simple. Also I learned, that with that size (rather small) and price range, the difference wont be really noticable. For more info on enclosure designs, I recommend the following video: ua-cam.com/video/ljuHHVznJJY/v-deo.html Thanks for your comment! :)
Great Build! Love it! If you want to, submit it to " projectgallery.parts-express.com "
Thank you! I just submitted it!
Great work! How much do they weigh? I am thinking of making the baffle of my next speakers out of concrete, but I am a little worried about the weight.
Thank you! One speaker casing weighs about 7kg/15lbs... So pretty heavy, but not too heavy in my opinion! They sound really good, unfortunately the built-in microphone of my camera doesn't really capture it :)
@@concreteeverything1605 thanks for the response. The weight is really OK for concrete speakers.
Geile Idee, geile Umsetzung! ...und ein echt klasse Ergebnis, sieht top aus!
