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

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. |

Sure, kind of; with outboard actively configured speakers just about the most elaborate kind of controls with everything from individual gain to each driver section, crossover points, delay, slopestyle and -steepness, etc. This is done via a digital crossover placed prior to amplification, and can be done from the listening position via a laptop/tablet realtime/on the fly. With the aid of measurements, the initial help from a friend well versed in this field, factory specs with recommendations and their measurements, lots of reading up and research plus countless hours of listening, the results have been fine-tuned to my specific acoustic environment and overall preference. |
