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.

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. |
My Apollo speakers are very adjustable in both the time domain and the amplitude domain via digital crossovers. All crossover parameters are easily adjustable. Adjustments can be made on the fly via tablet and multiple setting can be saved. I can toggle from one setting to another from my listening chair to compare or for different listening needs. Passive room treatment first then DSP is applied.
