DIY Speaker kit help


Hi.


Wondered if someone would be able to help me. I'm looking to convert an older wooden box single speaker into a unit that can house an Alexa device and speakers within it. I'm looking for a simple 2 coaxial speaker kit or order separate components so it can all be housed within the unit, and attached to the Alexa via the 3.5amp jack. I'd look decent quality speakers. But thinking under £30 seems possible?. Would anyone know where I could get these bits. Ideally would prefer not to have to solder


Thank you for any help, Dave

I did something like this using this box of tricks: https://www.kjfaudio.com/product/arylic-up2stream-amp-2-0-v3-wireless-streaming-amplifier-board/

It’s a streamer, a Bluetooth receiver, an Airplay device, and an amplifier. You can feed an Echo Dot in the 3.5mm input, but have the option of all the rest too. Toon recognises it as an endpoint. Mine drives a pair of recycled Mark Audio 11MS drivers easily. I built it into a single wide ply box sized up using an online calculator, divider in the middle, drivers at either end.  Because the drivers were from somewhere else, the total cost was less than £100.
Before hands are thrown up in horror... it sounds great in the kitchen! And it is wipe clean and has a single plug for everything.
Try going to DIYaudio.com for advice for this.

Still,l in your budget you probably can't afford a coaxial, so maybe best to stick with a single, wide range driver from FaitalPro or Peerless. They both make 4" or so drivers with excellent treble.
Hi. Thanks for the prompt replies. If I go for the amplifer board. I guess this needs additional bits such as power and looks like it needs an antenna too, is that right? So coaxial speakers come with wires attached and would it realistically need a separate base? Thanks again
I've found this but it's not mains powered and not sure how good the output will be?
