Question 1

What are the crossover frequencies at 8ohm? and 4ohm?

Accepted Answer

Numerous people have asked this same question and no one knows the answer. This is a low-pass filter, that only allows bass frequencies to pass to a subwoofer speaker. Unfortunately, the manufacturer has provided any details on exactly what the crossover frequency is. The crossover frequency will be higher when connected to a 4-ohm speaker than it is when it's connected to an 8-ohm speaker. Unfortunately, neither of these frequencies specifications are included.

It appears that there is also a high-pass selectable filter, that blocks frequencies below 0 Hz or below 8Hz. But there is no sound with a frequency of 0 Hz, so it's not really clear if it actually a high pass filter or not, and what speaker ohm loads these filter frequencies apply.

Given the complete lack of low-pass crossover frequency information, I can't recommend anyone purchase this crossover.

Question 2

How to install this? It has only one input and only one output. How does it divide the frequencies to the upper range?

Accepted Answer

Simple installation: connect the speaker to the output and the receiver/amp to the input, make sure the wires are connected  right  ( - to - and + to + )

Question 3

What is the crossover frequency?

Accepted Answer

50-60hz is stated on the Weah 90a product page

Question 4

can this be used to separate standard audio signal from stereo to filter out bass (22hz) for my amp driving a sub woofer?

Accepted Answer

No. This is not a crossover. It is not for two-way speakers. All this does is block frequencies abovr the cutoff frequency, which another person is 50 or 60 Hz per a spec found on Ailbaba.

This is not a two-channel circuit. It takes one channel of audio and blocks bass above ~60 Hz, mid-range and trebel frequencies fro being deluvered to a subwoofer driver.

Someone posted a 1-star review saying they installed it between the audio source and ampkifier and it didn't work. Of course it didn't, because his is a high-level filter. Not lune level.

I might buy this and test it for my application, which is to drive an older relatively small passive subwoofer from an old home theater system. This is to supplement my ADS L200C two-way speakers for a small office system.
