Design Goals:
I set out to make a robust speaker I can leave outside and throw around with all the bells and whistles. I have “mill speck connectors that you cant plug in wrong, Bluetooth, radio, flash or SD card built in and a line in with 5v for charging phone. All powereed but 600w rms amp

Crossover Design:
Dayton Audio XO2W-2.5K 2-Way Speaker Crossover 2,500 Hz
The Dayton Audio line of 2-way crossovers were designed using a second order (12 dB/octave) Linkwitz-Riley alignment. Dayton Audio metallized polyester film capacitors are used in both the high and low-pass sections.
Conclusion:
These speakers are very loud and do sound quite good. I do wish I added a port to them, I think I will do this in the future.
