I have an old set of 901 -II's. The active EQ only works on one side.
Before anyone posts that them not working is a blessing (I have a
restaurant I think they would be good in) I would just like to see them
working.

Question 1... Has anyone figured out the eq curve for these for those of
us with graphic eq's lying around doing nothing?

Question 2...Anyone know someone or somewhere that works on the active
eq's for these systems?

Thanks for any help and info

Should be easy to figure out and emulate unless it is
level-dependant.

Nope.

** The published curve for the Bose 802E equaliser is as follows.


20 Hz = -5 dB
30 Hz = -1 dB
40 Hz = +3 dB
60 Hz = +14 dB
100 Hz = +5 dB
200 Hz = +1 dB
600 Hz = 0 dB
800 Hz = 0 dB
1 kHz = + 1dB
2 kHz = + 4 dB
3 kHz = + 5 dB
4 kHz = + 8 dB
6 kHz = + 11 dB
10 kHz = + 15dB
15 kHz = + 17 dB


It might be smart to subtract say 8 dB from all the figures before setting
them on the sliders of a graphic to keep the plus and minus dBs even.

** Arrrgh - the OP has 901s - the home hi fi speakers.

The eq curve is similar but not the same as the 802 one.

Hope you get them to work! These are very satisfying speakers
to listen to, better than most actually.
