While I fully support people taking the initiative to build their own stuff, you’re going to end up paying several times more than it would cost to buy something off the shelf. Just so you’re aware. I’d be shocked if you could build something for less than $200, where you can buy something very nice off the shelf for $50-$100.

It can be made for way way less than $200…..maybe $50ish depending on what you already have and what you decide to use. The main thing is what speakers are you going to use?

Here’s a Bluetooth amplifier/receiver for $12:

Yeah, I made mine recently (links to parts in my projects) and spent way less (no rechargeable battery, though). It depends on how much stuff you already have. I got an oversized (for this application) power supply and bluetooth board (the one linked above) for about $22, $30 for a pair of 4” Kenwood speakers (lots of folks use cheaper ones), and $18 for the lumber (walnut and curly maple). All said and done, $70. It certainly sounds better than other bluetooth speakers I’ve heard in that price range, and definitely looks better (to me, anyway).

There’s another thread going about doing the same thing. It’s focused on finishing the cabinet, so it might not have popped up in any searches you did. Matt might be able to answer some of your questions.

Hi Guys….

There’s a ton of info on Youtube documenting BT speaker builds in various levels of detail….

I like a channel by a guy named Kirby who is all about building speakers and setting up amps, etc…

I actually find his build videos relaxing to watch and think his filming style is very good…. but he give links in his videos to all types of component suppliers. This is one of the good ones…

As for cost… I picked up the speakers I’m using NIB for free from the swap shop at the dump and bought the BT amp board for $12. I have a box of wall wart power supplies that I’ve collected over the years and am using panels from my scrap bin and one virgin board of poplar…. so depending on what you have laying around and how into it you want to get, the cost can be low or high… I wasn’t looking for hi fidelity, just something to kick out the jams in the shop that I can control from my phone.

I have less than $100 in mine. Box is built but electronics are unassembled because I changed amps after the first was a dud and then other things took priority. Some people use HiFi speakers with known parameters and calculate box size, others use car speakers and guess; I did the latter.

Daughter gave me a waterproof BT speaker – we are also boaters. I like using it in shop and around house doing project because I can hose it down when it gets saw dust and Sheetrock mud/dust all over it.
