I want to speak to people about room correction, and in particular raising troughs.
Let's look at the image below:
You can see a 10db trough at 70hz.
If you go with the default setting, Dirac will give you the ''red'' target line.
This means, at 70hz, it is raising the level by 10db.
It is raising level in a lot of other places, but bass puts most demand upon an amplifier, this much I know.
According to this chart:
A 10db change equates to an amplifier draw of .. 10 times as much power requirement (!).
However, the table does not talk about frequency. I might have missed it.
So my questions are:
1) - What kind of amplifier power do you actually need to run room correction with 10db gain at 70hz?
2) - Are you likely to see increases in distortion from your amplifier? If so, how extreme?
3) - Is physical damage to your amplifier, or speaker possible or likely?
In my own circumstances (it's NOT my graph by the way) -
I am running :
100w monoblocks
Sensitivity: 87dB SPL with 2.83V at 1m
I play music quite loudly.
I thought it a good point for discussion, and potentially something we should be aware of, if a danger in fact exists.
Thanks
And PS
sorry for the long absence. I rarely go on forums these days.
