Bass Control +3 db: how does it affect 100/50/25 hz?
Answered
If I set the BASS Tone Control at + 3 db, what does it mean for 100 hz, 50 hz and 25 hz? I can not find what kind of frequency curve will be applied and at what frequency it starts.
The information helps to prevent overloading the bass-loudspeaker (e.g. port-vented system: +3db at 100 hz, +6 db at 50 hz? That's a lot of energy).

When enabling Tone Controls, you are taking 6dB off the top to allow for headroom of adding bass. a +3dB Tone control results in a net -3dB of bass and a net -6dB of treble.
If you are concerned about overdriving your loud speakers, it may be best to consider a separate sub-woofer and enable it in your players audio settings. This will direct any frequencies below 80hz to ONLY the sub-woofer and not to the mains.
In many of our newer models this is an adjustable crossover to as low as 40Hz and and as high as 200Hz.

Hello Tony,
thanks for your response. I hope you/Bluesound will have a great, happy New Year!About the Tone Control. At first, I kind of thought my question is 'a bit silly'. Just play with the options, listen and enjoy. But: how many owners of an audio device with Tone Control know how it functions? I do not have measuring equipment.
I have 2 listening areas. One with Powernode Edge plus 2 'vintage', delicate speaker systems that will not survive playing at maximum power (I am not the only one using this audio-system). For a pleasant bass-response it needs a +3 dB control setting but that will also influence power-handling of deep-bass. No subwoofer, only the main listening area has a subwoofer.Solutions I use to prevent overloading the main speakers:
1. Set a 'Volume Limit'. Current setting: -18 dB.
2. Set Tone Controls to a safe level. Treble is at '0', Bass is at '+3 dB' for sound-quality.
3. Ultimate safe solution: Activate the 'Subwoofer' option, set the crossover at 80 Hz. I do not have a subwoofer so the crossover-setting will limit Bass-response of the main speakers considerable. (I do consider buying a subwoofer...). I selected 80 Hz because at 70 Hz there is a nasty room-resonance and that problem is perfectly solved now.Back to my original question: I am still uncertain about the increase of bass-power at low frequencies.
Set Bass Tone Control at +3 dB.
Does this apply equally to: 100 Hz, 50 Hz, 25 Hz? Is there a 'per octave' change?0 -
Changes occur at a uniform rate and are equal across the spectrum up until the crossover point. At which point there is a slight parabolic rollover for 20Hz above the the cross over point.
Sit back and enjoy.

Ahhh, my mind is at ease now!
Thanks Tony.
