I think B&O have the cut-off frequencies mentioned in the brochures.

Could someone tell me please how the BL5 & BL9 speakers work?

I mean, what are the different frequencies of each way (lower bass, upper bass, mid and treble)?

Crossover points are:

BLb 5: 120/600/2,000 Hz
BLb 9: 180/2000 Hz

Hi,

I didn't find these specs in the brochures I own.

Which brochure do you talk about?

Thanks a lot, that's exactly what I was looking for.

So lower bass are from 20hz to 120hz, upper bass from 120hz to 600hz, midrange from 600hz to 2000hz and treble from 2000hz to 20 Khz, right?

Cheers,
