New BRZHifi TPA3255 finished 2.1 amplifier - controls don't make sense!?

[Ralferator]

There's a 200hz low pass for the subwoofer

But that's very high. Also what's the slope? 12db? Would be much better to have a low pass at 80-100hz

The 200hz was quoted from Chinese website and not sure about the slope.

I'm OK with 200hz cause I'm using with small 3 inch full range speaker and a 8 inch subwoofer.

The subwoofer however is prefer to put it as center to improve imaging

Then i might fit. But for most use cases this low pass doesn't make much sense
