CX100 woofer question

12 replies

Hi,

Two questions:

  1. Are the two woofers in the CX100 the same?
  2. Do they cover the same frequences? With an other question, is the a two-way or a tree-way construction? What is the cross-over frequency or frequencies?

Best regards  Nis

1. No, they are different drivers.

2. CX100 is a three-way speaker. I don't remember the crossover frequencies.

The manual seems to indicate 140 and 2500Hz

I've always found it strange that B&O only supply the bass driver as a direct replacement part for both.

Which speaker is the bass driver?

Does the "middle" tone driver cover frequencies from deep to 2500Hz or only from 140 and 2.500Hz ?

Yes, that's the upper driver in the cabinet.

Hi everyone

I have recently put together the CX100 after refoaming the drivers and now I am confused.  According to the manual the layout seems to be as follows and that is how I installed it:

Top speaker     8480174   red and black wires   

Bottom speaker   8480173    orange and yellow wires    Speaker has the hole in the back

Martin seems to know that 73 goes in the top slot and in my case, this would connect it to the red /black wires.  So what is the correct layout for the CX100 drivers?

Thanks

Geoff

Hi all,

I would like to repeat my question about does the "middle" tome speaker cover frequencies from 140 to 2.500HZ or does this speaker cover the range from low to 2.500 so that the bass speaker helps from low to 140Hz?

Sorry for the confusion.

Part no ....73 goes at the bottom. That's the driver with ventilated magnet (the correct name for "the hole"). This driver is playing the role of woofer and midrange.

Part no ....74 goes at the top. This driver only plays as woofer.
