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!

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.

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

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?

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: kzitem.info/news/bejne/zaCrrnyMs6B7fY4 Thanks for your comment! :)

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.
