Tone Controls can be so nice.


Of all the ways to tame, tighten or tone the sound of our systems, cables are usually the first to come to mind. Preamps, amps, source and speakers are all chosen for what and how they contribute to the sound and each affect the other in ways that confound, amuse and satisfy.

Anyone who's paid even scant attention to what I like in my system knows that I've always wanted to hear further into the recording, extracting as much as possible from those shiny discs and not pay the price of loss of tone, richness or body. From sliver ICs to power conditioning and boutique fuses, each step has gotten me closer, revealing more detail, nuance, air and realism.

One day while listening I chanced to look at my Marantz PM-15S2b and it dawned on me that I hadn't tried the tone controls since the first time I tried them when new. I didn't like it then. Just switching it on without adjusting the controls it was evident there was a difference for the worse when used.

Time can do funny things. It may be due to something as simple as break in but when I engaged the tone control setting and adjusted the bass a tad (1 1/5-2db) a lot changed. Everything I liked about what I already have was fleshed out some more without a single, negative drawback. Tone improved. So did body. Percussion was easier to believe be it wood, brass, etc. Vocals had more chest and in the room presence. Piano had more weight, guitar more blues and twang (steel easier to tell from nylon). Even decay took on a different quality since the lower portion of the notes had more presence which led to a longer, more believable decay. Decay used to be the in the realm of the higher notes, the lower ones foreshortened, and now decay is across the spectrum which makes piano, upright bass, anything in that realm all the more authentic.

I dialed it back to just about a 1db boost and still had that magic. Nothing was shelved back, hidden or muted as a result. Just fuller, like a really good tube setup with great see-through ability. No bloat. No smear.

It's too bad that tone controls aren't in vogue nowadays. Blame the purists and thank those that still use them (Marantz, Luxman, Accuphase, etc.) I'm not advocating some all out assault with extensive equalization but in my case the bass boost is just at the 50Hz region and covers a small, but critical range for folk like me. My Tonians drop off at 40Hz and the drop slopes well before that. That little boost is all it took to even the frequency playing field, so to speak, making it seem all the more real. This is not to say I didn't have bass to begin with. What I did have had texture, detail, nuance but not enough force to have equal billing in the presence department.

If I had speakers that extended lower, all of this wouldn't matter. In my case it did. This is not to say that everything is better with tone controls but is some cases, certain recordings can use that little bit of boost and some systems, like mine, can benefit from it. It's been only a few days since I've done this but I've yet to tire of it and find myself loving what I'm hearing. Who knows?

Tone controls are not designed for room correction, but are intended to offer 1)correction of problems with source material and 2)mild accommodation for listener preferences. If for some reason a recordings has excess high frequency info a tone control won't eliminate the problem, but can go a long way towards making the recording more listenable. If you like to listen at low volumes (less than 65db), then you need tone controls to correct for the Fletcher/Munson ear sensitivity effect.

Room correction EQ is far more sophisticated than tone controls. A simple application is to use a parametric EQ to correct for the primary bass mode that occurs in every listening room. Vandersteen uses such a device in their higher end loudspeakers. Getting the bass right results in major increases in clarity/definition throughout the frequency range.
Mensch,
Sounds like a duck, walks a duck.
You certainly did make a declaration.
That's what these forums are for.
Enough with the jabs.
Deeper into the rabbit hole we go.......

LIke my experience with my Marantz (forgetting about the tone controls), I remembered that my Tonian Labs Tl-D1s are a semi-open baffle design and that there are three different vent settings on the rear side. No matter which size vent slat you pick, there is always a slotted opening above and below the slat that varies from a little to a little more or so on. Each one makes quite a difference from the next.

With my bass increase via the tone control came an appreciation for a fuller sound. Remembering that I had the vent slat in place that gave the biggest bass reinforcement, I removed it and left it open with nothing to block the sound.

Someone call the guys in the white jackets

I won't go so far as to say that I blew out the back wall but I did move it back quite a distance. Everything became so distinct that the sound no longer projected into my room but floated, instead. Now I think I get it: what some folk have described that I'm now hearing.

Putting in the smallest of the slats, I still retained that incredibly open sounding effect so I kept it in. Everything is so freaking distinct but it no way etched. Guitars, piano and vocals are the most realistic I've heard to date. I'm even going to go so far as to say I've never heard more realistic guitar sound anywhere, anytime. Closing my eyes completes the process. They're right in the room. Piano and vocals don't quite match the level of effect but I'm not going to complain one bit. They've improved enough.

Another neat trick is just how clear and distinct a drummer can sound, situated backstage behind the players. Whether brushing a drum skin or tapping the drum rim with his sticks, it's all crystal clear. It's that clarity that makes the layering so realistic. If one can pick out what's going on backstage it no longer becomes a distraction since you're not mentally trying to figure it out. It's just there working in concert, in it's proper perspective.

This has all made me appreciate the genius behind Tony Manasian's design. I always thought that 'Tonian' was some kind of take on his name but I feel it rightly belongs to the 'tone' that these speakers recreate. They are, indeed, instruments that can be tuned to your room, your amp, your ancillaries.

Before anyone goes out and gets a Sawzall and attacks the back of their speakers, please keep in mind that these speakers are meant to be tuned as a final step once all other considerations are accounted for. The vast majority of speakers out there are built as is so room considerations are what you should be looking into.

Is there a bottom to this rabbit hole?

I stand by my opinion regarding playback, tone control use by others, and my choice. Never intended a 'jab'. Dreadhead, water off my back.
Does anyone use balance controls anymore? A slight adjustment to compensate for speaker placement maybe? To correct what appears to be a problem in the mix? Is the less is more threary applicable here as well?
Mesch, my problem is learning to accept opinions that differ from mine. My bad.
