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.

Mine do not. Linn AV 5140. Each driver driven by separate 100W amplifier from within Akurate Exaktbox-i.

Lovely speakers from previous system now serving with updated amp and streamer.  No speaker-based level control.

Yes!

I saw the Advent loudspeaker mentioned. I owned a set of these which did have a toggle for attenuation. The three positions should have been labeled "muddy... bright... just right". That said they were a very good speaker in their day and are still fun to this day

I am focused on OEM Provided Level Controls and OEM Equalizers.

My contention is OEM controls ought to be provided.

OEM could offer optional equalizers for specific models

Certainly decent and sophisticated non-oem equalizers can do a terrific job, however that is not for most people.

A few who have controls do not use them. I certainly would get an inexpensive SPL, adjust them before room treatments. 

Amazon, 5 stars, $28.

Even if no level controls, these are great assists for refining speaker positioning and toe-in.

After you get 'best', then it's up to your specific taste, and hearing which changes as you age

 

The IRS Beta has exceptional level controls, both on the midrange panels and the xover/servo unit. They are a double-edge sword, however, because while they allow the system to be set up properly balanced, it’s also easy to get it very, very wrong. But of course it’s worth it if you take the time to get it right.
