It works and is good enough if you don't need something exactly. The HP section (tweeter) contains 3.3uF/0.4mH and 4 ohms in series - approximately 4.3kHz. The LP part (woofer) covers 0.8 mH / 6.8 uF - about 2.2 kHz. I used these 2 boards and some of their components (2 boards and 0.8mH and 3.3uF coils) as the basis for two high quality filters. (a 2-way crossover at 3.3kHz with LP/HP boards). I also rewired the 0.8mH with heavier gauge (and less inductance) wire. Money wise this was a good deal for me.
