Baosity 2 Pieces B-301 Way Divider Speaker Audio Crossover Filters Board DIY

They came on time. They sound fine. Thanks for your concern. Michael

I'm editing my earlier review that was too unfair - this product works okay for the money but it's not ideal. I will say the build quality is good. That said, one of mine arrived partially crushed, but still functional.I have not tested these crossovers with any instruments, but it appears the frequencies are not being split up effectively. I connected a signal from my amp to the input on the circuit board, and then tired the same signal directly to the woofer - they sound nearly identical. I tried with the mid and tweeter, and got the same results.The product is labeled 1000mhz-5000mhz, 1000 being the low end of the range. A good bass driver range should be more like 150-300Mhz. This makes my speakers sound okay, but they would sound better if I got better designed crossover assemblies. When I turn the volume up high, I have to adjust the EQ quite a bit to keep my speakers from sounding like garbage. When I do, it actually sounds pretty good - for the money. You get what you pay for!

4 stars because I don't like the low pass filter, not as low as I was hoping for. But otherwise it works great
