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

This crossover over does the job of blocking high frequencies from getting to your single subwoofer. 2 wires (+ & - ) in from your amp, & 2 wires (+ & -) out to your sub. The switch either blocks upper bass from getting to your driver or allows it. You can hear the difference. That why they state the 8 Hz position is for a woofer (allows more upper bass through) and the 0 Hz position (does not allow upper bass through) is for a sub, but set it where it sounds best in your system. I don't fully understand the labelling of 8 Hz and 0 Hz.I am using this on a 30 watt per channel home receiver and some very small Polk speakers for the mids and upper frequencies, so I cannot evaluate it for high power applications. Right now I am using it on the left channel. But when you do this, you are missing half the bass. So I just ordered another passive sub and another crossover for the right channel, then I will be hearing ALL the bass. This is the lowest cost crossover I could find. You'd be hard pressed to roll your own at this $10.00 price point. I wish it had more specs and a schematic would be nice but you can draw one up yourself. Amazon has a Nippon sub crossover for $14.00 with more specifications, so maybe that one may better suit your needs. So Qianson, how about a data sheet and a schematic?????? This is my review; thanks for reading it. Happy Listening !!!

The goal was to send only bass frequencies to the subwoofer. So far it seems to work but without putting a scope on it it is hard to tell for sure

I had a cheap 8" powered subwoofer that a friend gave me when the power supply went out in it. I decided to just take the powered guts out and make it a passive subwoofer for a small amp that I have. For about $15, and a little time, it ads some nice bass to the bookshelf speakers I use with that amp. It's a small room, and I don't want to knock down the walls with booming bass. Just add some bass for the richness it brings. This accomplished that.I'm no audiophile, so I have no idea if it would be good for that type of system or not. But for what I needed it for, it exceeded my expectations and I'm happy I got it.

Did not work right out the package.

In fact, if anything it seemed to act as a high-pass filter. My sub was receiving full range, less the bass, frequencies regardless of the switch setting. And No, it was not wired incorrectly. Going back - tired of buying things that don't work.

Built a outdoor custom patio subwoofer and needed a passive X-over . This fit the bill , and it worked out perfectly !!!! Great product , great price and very well made !!!!

What it is, is a low-end woofer crossover that should be used in a regular 2-way speaker crossover network-configuration. True subwoofer crossovers rarely crossover above 150Hz. This one crosses over at the 3,500Hz-4,500Hz range. Making it more like a midrange crossover than anything else. It did not serve my purpose.

Just what I needed
