Hi All!
After spending a lot of time trying to choose which bluetooth speaker to buy, I got the idea that they were very overpriced, so I decided to build my own. I've never done a project like this before, so I'm a complete novice at it, but I like the idea of building my own speaker. At the moment I have the following plan:
Speakers:
Dayton Audio RS125-4 (5 inch , 30W, 65-5,400Hz)
Dayton Audio DC28F-4 (1 inch, 40W, 3,000-20,000Hz)
Crossover: Dayton Audio XO2W-2,5K
Amplifier: Sure Electronics AA-JA31213 1 x 60 Watt Class D (I'm least sure about this choice because this amp has 24V in its specification, but there is for example a TPA3116D 2x50W that operates between 5-24V)
I plan to mount these in an 18mm MDF enclosure of approximately 300x200x250mm with a 50mm diameter bass reflex tube.
What do you think so far about this setup?
How do I exactly tune the enclosure dimensions and how does this match the length of the reflex tube?
What battery is needed for this setup?
Thank You!

The second amp has a TPA3116d IC too and will give 60 Watt only at 24 Volt,4 Ohm speaker imbedance with 1% distortion.
With 4 Ohm load, at 12 Volt and 1% distortion it has only a maximum output of 15 Watt (yes, only fifteen W).
You will need some quite expensive and/ or heavy battery and some complicated charging stuff as well. If you go Lion battery, only store the finished build at a place that is safe when it burns off. No insurance will pay for a fire started by a DIYS build. Think about it.
Maybe buying something factory finished is the better idea. In the end you will spend more money on a DIYS than you think, with a questionable result.
One hint: Universal crossovers don't work as you might think. They don't match sensetivity, impedance and frequency response of the driver you connect. All they can do is prevent the tweeter from blowing on the first try. A crossover has to be individually taylored for the drivers used and the baffle they are mounted on. Please read some basics about speaker building. Don't waste your money!
