"You DO realize that when you change a frequency band on a graphic equalizer that you are also changing the adjacent frequencies. Only a parametric EQ lets you control the width of the adjustment."Incorrect, adjustment occurs within defined bands and the difference between both types of equalizerss is the width of bands, fixed with a graphic equalizer, variable with a parametric equalizer. In other words, a parametric equalizer permits much finer adjustment.
"And a speaker that can't reproduce low frequencies will NOT be able to do so just becuase you moved a slider on an EQ"
Depends on the drivers in question! Ask Merlin and Gallo, they both use one (BAM i.e Bass alignment module) to extend the bass response of some of their models.

But sometimes the source material is to blame -- not your system.All recordings are mastered to suit some other guy's taste, with his EQs, on his monitoring system. Imagine if he masters on Duntech speakers, but you listen on Tannoys ... etc. etc. No recording can be expected to translate perfectly from system-to-system, since there is really no objective standard for the recording/mastering process.
Nevertheless, I don't use an EQ or tone controls, since I don't have either, and can tolerate some inconsistency. Furthermore, I cannot afford an EQ that I'd trust in my system to not mangle the sound. But I think it's much wiser to tweak EQ than cables/cartridges/tubes if you are trying to fix a frequency balance problem which is intrinsic to a recording.
"But sometimes the source material is to blame -- not your system."Exactly...

Well, you are wrong, it is not a "graphic equalizer", but it is most assuredly an equalizer, most likely with the exact same restriction as a graphic equalizer i.e. fixed bands of equalisation.

Ozzy, you got it when pointing out that a graphic EQ will affect the frequency response out of band with the slider. I've never seen one that didn't.Audiohobby is correct in that the BAM and other EQs like them are equalzers, although not *graphic* EQs as Ozzy asserts.
Although EQ can help out certain situations if used sparingly, one of the prices paid is that the signal is going through a circuit of (for the most part) horrendous design- cheap parts, poor layout, cheesy power supplies and the like. No-one makes a high-end EQ right now; the closest I've seen was the old Cello Pallette. Having solved most of the issues I listed, it worked fairly well. These days their power supplies will have to be rebuilt to get one to work up to snuff...
"No-one makes a high-end EQ right now; the closest I've seen was the old Cello Pallette."Don't forget about all of the great mastering EQs available -- most albums have already been through one or more of 'em. Certainly not cheap (at the high end), but neither was the Cello.

I didn't assert any such thing.
The BAM is a little box. The EQ network provides a little bit of bass lift and then rolloff of the extreme lows. Being a dedicated box, it does not have the out-of-band behaviours that graphic EQ units do!
" Being a dedicated box"What does a 'dedicated box' have to do with anything. It is a fixed band equalizer, How does BAM move the -6dB point from 37Hz to 29Hz without affecting adjacent frequencies, afterall the spec claims that the 5.2dB boost is applied @35Hz.
"it does not have the out-of-band behaviours that graphic EQ units do!"
And you will be wrong because you can implement a graphic equalizer as a fixed band parametric equalizer, which is essentially what the digital equalizer's do.
