Azuocn 200W Pure Bass Subwoofer Crossover Second-Order Crossover Frequency Distributor Divider 2 Way Speaker Audio Crossover Filter (A)

Yeah I was trying to fix a little Sylvania base speaker that I had with built-in amp the RCA plug in for the sub was bad I was clicking and cutting out bad replaced it with a 5-in pile xgear subwoofer but was unable to get the true base because I was using a center speaker plug-in on the back of the amp to power it this little crossover as soon as you hook it up it just converts to straight sub with a switch works great hooks up easy actually has some Kenwood parts to it yeah converted my sub back to a sub highly recommend five Star product works for home audio stereo check it out try it for yourself won't be disappointed I got the ones with the quick release tabs on it instead of the screw tabs there's a A and B model so check them out

They don’t advertise the frequency this crossover is at. There is a switch on it for 0hz and 8hz, which just leaves more questions than answers. It doesn’t filter out much of the highs, better than running sub at full range I guess. My best guess would be around 200hz at “0hz” and 250-300hz at “8hz” as far as the switch. I would estimate it only a 6db cut, even that seems like a stretch as you can clearly hear voices and frequencies as high as 1-2khz through the woofer I was using. There’s not much out there in the way of passive low pass crossovers dedicated to subwoofers, but this one doesn’t perform well at all.
