    My Q1's are powered by an SR5400 - how far can I oush them? I had them at -5 and am not too sure about pushing them any further.

    Your speakers can take anything your amp can dish out, unless it starts to clip. As soon as you start to hear distortion lower the volume. If you are driving 5 of them from that amp I'd guess it's pretty close to its limits.

    Does the same apply to most setups? I have just been watching Terminator 3 at about -25db. The loudest i've had my amp is about -17db. Anymore than this and it would become uncomfortable. Could it be to do with the size of my room?

    My amp is the Yamaha 640SE. Room size approx 4m square. There has never been any sign of distortion/clipping.

    I suppose the larger the room, the more volume would be necessary?

    The volume levels you are giving don't mean much unless the amp is calibrated. This normally done with an SPL meter or by the unit itself if it has such a facility. My recieiver is calibrated to reference level (105dB on the 5 speakers) at -0. Of course this is only for movies. Music and other sources have different levels plus some DVDs are mastered to higher or lower volumes levels than others.

    When I said his speakers could take anything his amp could dish out I was going by spec. speakers can handle up to 120W which is more than his amp can do. However if the amp starts to struggle the distortion can be, unpleasent shall we say, for the speaker and lead to damage. It is more common to damage a speaker in this manner than through over-powering it.

    In a larger room, more power will be required to reach the same volume, hence the need for calibration for a comparison between systems to be valid.

    Where should the sound level be measured? At the listening position or in fron of the speaker?

    You should measure at the listening position.

    Forgive my ignorance.

    After my last thread regarding safe volume levels, I got a Lutron SPL meter and have proceeded to check the speaker balance using DVE.

    I have also just had alook at the links you posted, I still am nor clear on how to calibrate to reference levels. One of your links recommended setting the volume and channel gain so all channels measured 75db on DVE; would this volume then be the designated reference level for my system? What is the 105 db level then, is this the maximum? If so how do I go about measuring the maximum; :lease:
