DIY simple (and cheap) tweeter crossovers explained -- how I wire up my Bluetooth speakers
Вставка

- There has been many asking for schematics and parts breakdown for my DIY made portable Bluetooth speakers. Hopefully, this explanation helps others how to get a decent (and low cost) custom tweeter crossover for your projects. This example is about as simple as it gets and not audiophile high-end crossover engineering -- designed with high dollar test equipment. IMHO, trust your ears -- the best test equipment money can buy. Just play around with resistors and capacitors to find what works best. I have used capacitors and resistors as crossovers in all of my builds vs pre-built ones that are not customizable. Here is what I used for a crossover in this build:
50 uF (100v) capacitor on Amazon

100 watt 47 ohm resistor on Amazon

Tech me up! I'm ready!
Hahaaa! I just wanted to keep things as simple as possible without requiring a degree in electronics and $50,000 in test equipment to explain. Bottom line, ones ears are the best judge of quality. Man, you should hear this greenBooger in action...totally all there. Got some Triumph (Allied Forces) jamming right now...sounds butteryBadazz.
@@ChrisDIYerOklahoma lol right on! I'm looking for my Triumph album right now lol

Did you use that 47 Ohm resistor in addition to that Capacitor? I used 33 Ohm Resistors in front of tweeters, and it sounded good.. I'm not understanding the Capacitors role, and where it is wired in that box.. seems like they are both knocking the power down, so is the Resistor and Capacitor just two different options for achieving the reduction in power? Thanks!
Short answer...yes. The resistor knocks down the power (wattage) going to the tweeter. The capacitor is a "filter" per se...filters out freqs below ~1,000 Hz in this application (4-ohms). So, yes, the capacitor knocks levels down by reducing lower frequencies from damaging it...a poor man's crossover that many people use. However, a tweeter can still sound "hot" even with just a capacitor. The resistor is what really decreases the total power (SPL, wattage) going to the tweeter to help balance it's output to the full output of the woofer. Each setup out there is unique...you just have to play around with resistors and capacitors to find the "sweet spot" that sounds best to you.
