The curve for the Bose 802E equalizer...WOW!

Zombie thread warning. Looks like it is getting angry as well. Best to leave it alone before provoking it further.

They were posted to another forum most likely from the 802 owners/service manual
I would think that with Pro equipment specs must be available for any professional use in clubs, etc.

Those numbers are slightly CONSERVATIVE compared to the EQ needed for 901 Series I & II!

From what I know so far the 901 Series I/II (I have Series II and 4) need the most EQ as they use the sealed cabs
and do have a reputation for needing the most powerfull amp's compared to the Series III and on.

yes it's a result of my never ending Google search and wanting to bypass the Bose EQ. I have two 10 band per channel EQ's just sitting around so I will give it a try in a few days. The thing is even when you buy the right Bose EQ for whatever Series your 901's are you still have the problem of 30+ year old caps that would need replacing. I'm not able to do that so how much more $$ is needed to get that old Bose EQ back to factory specs?
It's not a pretty picture for sure.

As I recall, the 901 EQ was a piece of cake to recap; one circuit board that comes out of the cabinet so you have access to both sides of the board, and around a dozen caps to remove and replace.

Parts cost would be under $15 if you bought each cap individually from a hang tag at an electronics store, and less ordered in bulk. Maybe an hour of soldering and screwdriver time.

The response curve of a purpose-built EQ will be much smoother than the zig-zag curve of a graphic EQ when taken to it's extremes.

Will a graphic EQ improve the sound of an un-equalized 801/901? Yes, but not as much as the real thing.

I agree that the purpose-built EQ is better than a tuned GEQ, but the actual response of the GEQ is not zig-zaggy as one might expect. I wish I could find the curve I measured using GEQ.
