Pasta Prime Posted July 30, 2014 Report Share Posted July 30, 2014 So I decided after not having any tunes on my deck that would build my own bluetoth speaker because one the ones like the Pill or Jambox are spendy, and two it would be a fun project. Because hell, I don't have enough of those. lol Not sure on the design yet but i want it to be on the smaller side. Here's what I am thinking: Amp+bluetooth+power supply https://www.parts-express.com/lepai-lp7498e-200w-class-d-digital-amplifier-with-bluetooth-and-power-supply--310-298 Full range speakers 4 ohm https://www.parts-express.com/celestion-neodymium-5-full-range-woofer-4-ohm--299-414 Tweeters 8 ohm https://www.parts-express.com/1-2-mylar-dome-shielded-tweeter-8-ohm-with-33-ohm-resistor--279-001 Ok so my question is: If I do decide to run the tweeters do they need to be 4 ohm also and if they do would an inline capacitor work and if so what cap do I use? Just a thought about the tweeters not sure I would even need them. New build coming........

timc31610 Posted July 30, 2014 Report Share Posted July 30, 2014 Looks like it will be a cool little build, I have thought of doing something similar. I would run the full range at 4 ohms and use 8ohm tweeters wired in parallel for a 6 ohm load. But those full range speakers are only 25 watts rms. Wired in parallel assuming that amp puts out rated (i doubt it will) you will be overpowering them. I would look for something in the 75 watt range.

I was being cheap. lol So if I want to run the tweeter parallel with the full range they have to be the same ohm correct? New build coming........

timc31610 Posted July 31, 2014 Report Share Posted July 31, 2014 No, they can be different. The higher coil rating on the tweeters will keep them from being overpowered. Higher resistance = lower power.
