nice gesture. On devices that I received at least.

They came first with a circuit that felt good. On the devices I've at least received, the 2.6 mH inductance was actually only 1.3 mH. I discovered this after sweeping the frequency with a function generator, 4 channel oscilloscope, etc. Finally, I simply unsoldered the inductance and measured it with a B&K LCR meter. After rewinding the inductance by 2.6 mH I now get a crossover from the woofer to the middle as indicated. Out of the box it cuts closer to 1500Hz. I suspect the inductor was…

Pros
  • Includes: 2 x Crossover Filter Frequency Divider; Rated power: 180W
Cons
  • Crumpled packaging

Very satisfied! in filtration

It's been a few years since I bought them. I built a grotesquely large set of desktop/bookcases/computer speakers for use in my office/media room. I've tried other three-way crossovers and it's nowhere near the success I've had with these. In fact I'm here to buy more of these and when I added them to my cart I realized I had never left a review. These speakers with these crossovers give me and everyone else goosebumps when we listen to music or movies. Everything is so alive and clear that it…

Pros
  • Product name: Crossover filter divider; Colour: white, red, yellow
Cons
  • Big and chunky

Good crossover, but has a technical flaw

This is a good crossover, but two comments need to be made (a) It's rated for 4 or 8 ohms, but with that it works properly, all speakers must have the same impedance. b) technical error. The woofer and tweeter use 2nd order circuitry, resulting in a 180 degree phase change in the output signal (the midrange uses a 1st order network). The woofer terminals are correctly labeled as the correct phase (i.e. the + of the woofer is connected to the - input), but the tweeter is labeled reversely. This…

Pros
  • Output impedance: 4-8 ohms
Cons
  • Not as thick as other picks
