Measurements
Contents
If you start measuring custom install speakers, you will immediately notice that they are tuned to measure optimally at the listening position: not directly at the wall or at a distance of 1 meter. We measure a much better response at the listening position. That’s about 3.5 meters from the speaker. We put the microphone in the middle there: the sweet spot. That this measures better is also logical: less reflection / energy from the wall. And the manufacturer’s tuning. Nobody sits in front of the speaker at a distance of 1 meter.
Of course we still measure a bit of ‘wall’ – it’s made of wood, stone measures differently – but it’s fine at the listening area. The room is quite subdued and not yet acoustically optimal. It may be attenuated a little less afterwards. We see some high-waste, although that can also be the off-axis response of the softdome.
Measurements show that the DALI is nice and steamy from about 50 Hz. A sub in movies is allowed. Though we’ve run without and it’s going very well. The dip you see in the graph depends on the position of measuring – cancellation – and the time-window we use (in short: the distance to the wall and extinction by phase). Don’t worry. It’s not in the speaker.
The distortion is very low. At about 70Hz it dives below 1%. Minimal distortion is around 0.15%, which is neat. Here DALI shows that this is a serious speaker.
Hi, I am curious about the Dali phantom sub s-100? I would also be very interested seeing an in room response curve. Thanks in advance.
We have only heard the S-100 in a demo at Dali Benelux. Very nice sub. The measurements supplied in the review is what we have.
