Equalizer in a Hi Fi system

I believe it is advertised as ‘environmental’ or room corrective, yes?

Thanks very much for your understanding and kindness ...

You are right for your observation  about the "cat" in my book ...😊

@mahgister , I found your last post very interesting and informative as well. More than one way to skin a cat!

@mahgister I actually love your idea of tuning the speakers to the room.  Any good designer knows that the low end is EXTREMELY room dependent, and not every speaker is perfect in every room, or in every position of any room.  Your tuning-straws are a great idea, if probably a bit unsightly!  My oldest speakers are B&W Matrix 801-S2's, and I love them to death.  In my music room, with slab foundation, the low end is tremendous, and I needed to put them on 8" stands to tame the bass.  Then I flipped the furniture 180, and on the opposite wall, they sounded like a disaster.  I moved them to my living room with raised wood floor, and they sound PERFECT on the floor with no stands.  So how can a speaker designer align a low end response that will work in all rooms?  It's impossible.  

@tlcocks Yes I know of the MAAG eq, and I asked the designer if he'd make a version with ganged controls.  He said no.  So I will not buy a MAAG, but the Skyline M3D is very MAAG-like in its design.

I do not use a separate Equalizer. All digital preamp processors have EQ capability of one sort or another. The ones I have used and use currently have EQ in several different forms. The first is your typical parametric EQ but with frequency and Q selection and the second is via Target curves. Parametric EQ can be done on the fly whereas Target curves are designed to address specific problems. As an example some recordings might have a tendency towards sibilance. So I programmed a target curve with a Gundry dip in it. I have a base target curve that tells the system how I want it to sound from an amplitude perspective. 

Preamp processors available now are the MiniDSP SHD, The Anthem STR, the DEQX Pre4 and 8, and the Trinnov Amethyst. They range in price from $1500 to $13,000.

The PEQ in the processors I mention above are GUI style ganged controls. You adjust them on you computer and they can be used on the fly.
