How loud is -20db?

Seen lot of people tend to watch films at -20db but how loud is this, around 90db I am guessing? Not too bad. Like having decent volume level on films when neighbor is out but want to know first, today I played pacific rim for 5 mins on 15 volume on my sony str-dn1040 using dali ikon sub mk2 and it blew a light bulb!

I used to listen at -25 on my amp but since I've done an auto set up and upgraded some of my cables I can now listen at -20.

For the size of you room mate I would have thought -25 would be fine. Up to you of course.

Humm I tend to watch at -31

Humm I tend to watch at -31 to -37 which gives me dialogue at 50 to 60 dB's , that feels right , crash boom bangs are louder of course.

I generally watch around the

I generally watch around the -20dB mark - just seems comfortable for me - not too loud, but not too quiet either. Even if the neighbours go out, I don't edge it up much more than that, maybe -15dB tops.

Is that +10dB on the speaker levels on the receiver?

Then I'm not surprised you're

Then I'm not surprised you're blowing light bulbs! speakers will be next to go! wind those levels down some. I tend to be same as David, -20db for regular watching, crank it up a little for certain movies though.

Unless the centre speaker is particularly hard to drive (or the centre is maybe a sealed cabinet), there shouldn't really be a difference of 7dB between it and the front pair. This will give quite a focussed sound and drown out much of the sound produced by the rest of the speakers, which is fine for dialogue based movies, but not for anything with any effcts or ambience. I agree the centre should usually be boosted a little - I usually add 1dB to most auto setups, which seems to work nicely, but it shouldn't be so much more than the rest of the speakers.

As for the sub, if the level of the sub is too high on the receiver, it can overlaod the output and send a distorted signal to the sub when played at high volumes, so all your sub will be doing then is amplifying the distorted signal it is receiving. This in turn just draws attention to the sub.

I'm just glad I don't live

I'm just glad I don't live next to any of you guys, especially Nuggett. I tend to watch tv at -30 to -40, but with the dialogue level raised to +3. I watch DVDs and Blu Rays without the dialogue level raised, but still only on around -25 to -35. Since buying the Zensor 3s, I no longer bother using the sub.

I have re calibrated and it

I have re calibrated and it worked for the sub this time with gain set to max so it can hear it. Still too noisy it says though but no error for the sub anymore. Set centre to +5 instead of 7 see how it sounds. Set sub to +0db see how it sound also for movies. I think for music I would have it turned off at that volume of the sub though doesn't add that much

messed around with settings

messed around with settings and the centre at +2db now i can hear volume good! must have changed after intergrating the sub into my system.

 

the sub set to +0 didnt sound that great so i turned it to +6 but it was quite bassy so turned it down to +4db, see how it goes.
