Like to have some loud music on sometimes with sub blasting away but I'm scared that if I turn it up anymore it will break. I don't hear any distortion of the sub at all at that sound level but just how much the driver is moving I think surely it can't take much more. Subs on 70% gain and I stream music via AirPlay on deezer to my str-dn1040 av receiver at about 15-20 volume which is around 75-90db most of the time.
How do I know when my sub is reaching its limit?

Generally, if he starts to smoke, it's the announce it was too much. Did your sub not have a clipping protection ?

I'm assuming you've measured the sound output at 70-90db? If it sounds fine it should be fine, the drivers will move a lot at higher volume that's how they produce bass.
I think you're worrying over nothing.

Possibly when the whole of the Danish Navy heads out searching and several Russian 'merchant vessels' start zig-zagging a lot. *biggrin*

no I've not measured the sound. I tried to do it but it just seemed confusing. I ran test tones with a spl meter but I am not the best with knowledge of setting this stuff up. It's the Dali ikon sub mk2 so dunno about clipping protection. How can I calibrate the volume of sub correctly?
Edit: I thought you meant calibrated the sub to 70-90db. Yeah a few times I've got the meter out. But to take the measurement do I stick it directly in front of the driver to get max measurement or at seating position? I'll try again later when I watch a film and see what volume I get
Also if anybody knows, will my sub play down to 20hz? It says 26-200 response on richer sounds but I've seen people talk about -3 or -6db etc meaning a sub can produce lower notes in different positions of the room.

As you go up the frequency range from 0 to 20kHz, in an ideal world speakers and amplifiers etc would respond uniformly so that there is a constant output no matter what the frequency. Amplifiers have to cope with a wide range of frequencies and they are designed to have as flat a response as possible. Speakers are limited by their physical size. A tweeter being small will have a maximum response in the high range at several thousands of cycles per second (kHz) whereas a woofer being large will respond more to frequencies at the low end e.g. 100 cycles per second?
As you move away from this peak either up or down the frequency range the response tails off until at a particular frequency the level is 3db below the peak. These are the 3db down points (-3db) and it is the range between these points that is defined as the bandwidth. The speaker will respond to lower and higher frequencies, the response does not just stop at these points so you will get a response of some sort even at 20Hz but it will be less than it is within the specified range of 26 to 200Hz.
Crossovers are used to enable high frequencies to be applied to the tweeter and low frequencies to the woofer, etc. There is no point in applying power to a speech coil without the benefit of some sound being emitted. It wastes power and could damage the speech coil. Crossover filters do not cut dead at a set frequency. The response overlaps somewhat. There is, as far as I know, no such thing as a 'Brick Wall Filter' where the roll off in response is in effect infinite.
As to the limit, well if you find the cone attached to the wall on the other side of the room I think it would be safe to assume that you have overdone things slightly!
Hope this helps

Your sub has protection circuitry so if you haven't tripped that, then you should be ok. Unless you have violent neighbours, that is.

It would kill the sound, so you'd deffo notice. I hope
When I had a 6.1, in my previous house, the REL Quake I had worked well within limits. Moved to a bigger room, in my current abode, and it could run out of puff. I was watching a Star Wars film, where someone or other was sinking into a river of molten lava, where the low bass ran consistently for quite some time. Part way through the scene, the sub went 100% quiet, but returned to normal later with no long term problems.
So stop worrying.

Hi Nugget! If you had violent neighbours you would know by now, unless they were deaf. Mind you they probably will go deaf if you keep playing your sub too loud *stop*
