anyone ever played their SVS at full blast?

Hi guys,

Been an SVS owner for close to a year now.
just wondering if anyone watch a movie with the sub turned up?

I have never done it.
Watched U571 on maybe a little higher than normal volume...but everything tuned normally. And a couple of people had to leave the room.
After a couple of scenes i had a headache.

You could really feel the pressure.

After that experience..never really wanted to go all teh way..afraid of damaging stuff.

So anyone blod enough to try it?

No offence but it's a meaningless and silly question, as there is more than just the "volume" dial on the back of the sub to affect its output. Also with "everything" turned up to the max ANY and EVERY subwoofer will sound horrible, and so much depends on the room.

Why is it silly?
Just wondering? I don't mean you have to turn EVERYTHING up.
Only the SUB.

Maybe the amp and speakers play at normal volume...but you crank up the SVS all the way.
To put in perspective..the amp on the SVS is tuned at 20% of the volume. At 75 db i play the SVS a little hotter with +1db.

It's still a mystery to me why AV fans don't quote peak dBs on film sound rather than talking about reference level. Which is virtually meaningless IMHO as regards maximum sound pressure level reached in the room during a particular scene.

So much depends on the equipment settings. Then there is the level of accuracy achieved during calibration. The test tones are capable of some innaccuracy I believe.
Give or take the odd dB (or more) of peak or trough in the room's response.
Then some like it 'hot' as well. The SPL meters are often wary of low frequncies. It's all beginning to look a bit iffy.


One model of subwoofer (even from the same maker) is quite unlike another in the product range. Subwoofer frequency response is very room dependant. One wonders what it all means in real dBs of 'grunt' at the listening position.

Not that I'm trying to pick an argument of course.

I do agree about the headaches though. Is this really a sensible basis for a hobby?

I have measured over 110db with no problem thanks to some overlapping room modes. BTW it wasn't on purpose I finessed the volume control in the wrong direction

ITs a simple question - trouble is (no offence), your not dealing with simple people, well for the most part anyway.

Generally because I can't be arsed sitting there with an SPL meter in my hand when watching a movie

Good point though, especially when auditioning subs etc.

Nooooo! Don't start that.

It'll turn into a peak SPL arms race and someone won't be happy until they've blown out the windows, demolished the walls and killed several passers by.
