Do Your Speakers have LEVEL CONTROLS or EQUALIZERS? (Vintage or Modern)

MANY Vintage Speakers had/have Level Controls, and a few big speaker arrays had external equalizers.

..............................................................................

Many of you know It’s my contention ALL SPEAKERS should have Level Controls, to refine their frequency distribution in your space at your positioning in that space, and re-adjust for any space you move/use them in.

L-Pads retain impedance shown to the crossover; Potentiometers alter what is shown to the crossover a bit.

Just stumbled about these

After a few times, it get's very easy.

1. Image MUST be on the WEB, not on your computer.

2. Find Image on Web: right click it

3. 'Copy Image Address' (not copy image)

4. Here, in the window, top bar, click 6th ICON from the left: IMAGE

5. Pop-Up Box Appears, 'url address' default top line

6. Paste Image Address you copied (or go get it now)

7. Wait until the Image Size automatically fills the two size boxes

8. OK, image appears in your post.

 

 

My Yamaha 670s  (which I purchased new in 1975) have mid and treble adjustments.   Never used them.  Just set them  in the middle.    My  Boston Acoustics 975 however, have powered subwoofers, and I use the bass adjustment fairly frequently

While I agree that speakers benefit from being able to be altered for different placements and rooms I disagree that L-pads or even switched R arrays in a passive speaker are desirable. They are crap for reliability. Professional, active speakers have these features and IMHO are the correct way to implement them.

Also, adjusting individual drivers is not really as good of an option for adjusting the output as having an upstream EQ or tone control.  In general, the crossover points of a speaker and the human hearing and studio choices may or may not match up.  The "loudness" button on my receiver will work correctly regardless of the speaker design.  I'd hate to try to achieve the same thing with a set of level controls on a 2 or 3-way speaker.

 This was exactly mine... I owned two sets...

They were too big for my desk ... i sold them BEFORE learning small room acoustic Alas! ...
