Hello, I am new to the DIY community and wanting help with building a Bluetooth speaker.
Speakers:
https://www.parts-express.com/Tang-Band-T1-1828SD-Speaker-Module-4-Ohm-264-935
https://www.parts-express.com/HiVi-TN25-Fabric-Dome-Tweeter-297-408
I used a speaker crossover calculator and came up with below. Cam someone check this out and tell me if it will work for a small Bluetooth speaker?
2nd order link-witz Riley. Crossover showed that those two speaker should be crossed between 6600 to 6700 I think.
The Component Values are:
C1 = 2.4121 µF
C2 = 3.0151 µF
L1 = 0.2411 mH
L2 = 0.1929 mH

Why sure! Start here!
No offence, but you can't use those calculators for speakers. You want a pretty linear response in the desired frequency range. Speaker units aren't linear by default. Even worse, when you put them in enclosures, linearity becomes worse. You have to correct for that, otherwise the result will sound awful.

Goodcomputers locked my PC up so badly I had to turn it off. C1 C2 L1 L2 are not universally named and could be combined 4 ways.
The parts express parts have no Fs Qt Vas specified. The tweeter doesn't even have an impedance. This makes any calculation a complete dice throw. Why would you want to spend $50 in crossover parts for $37 in drivers? The tang-band 2" "woofer" is listed as full range anyway (assuming nobody wants to hear below 75 hz). Put a cap series it and forget the tweeter. 530 uf is 4 ohms @ 75 hz and more below.
Most men that have used loud motors, fireworks, firearms, loud music in clubs, can't hear above 7000 hz anyway. Test your hearing with headphones before wasting money on tweeters.
