Magico S5 measurements: lowest distortion level ever measured by Soundstage

Canton Chrono SLS 780 DC:

and for reference

Magico S5:

Like I said before; Distortion is non-existent (THD = non-issue), and Power Response is superb, all across the entire audio range (cohesion).

Interesting FR for the Canton. The bass is dropping like a rock starting at 100Hz while the S5 is basically flat. But why do both of these graphs cut the bass off at 50Hz? The both obviously have bass below 50Hz. Also, the Canton appears to have a huge suckout between 1Khz and 2Khz due to the crossover.

Hi,

I just have to jump in about the Canton post -- that is NOT the chart from that speaker. The link to the measurements is here: http://www.soundstagenetwork.com/in...&catid=77:loudspeaker-measurements&Itemid=153

As for what the FR and THD at 90dB look like, I've attached that plot.

Doug,

You are correct. I made a mistake posting Paradigm's graph twice.

Here is the correct graph for the Canton - better, but still far from ideal:

PS. The one you have posted is 90dB graph, which cannot be directly compared to the 95dB graphs I posted; 95dB graphs always look worse, as THD increases with volume level.

Hi,

Agreed on needing the 90dB. Insofar as "far from ideal" goes -- that Canton speaker is $3600/pair and it's frequency response is very flat, bass very strong, and distortion is exceedingly low.It's not lower than the Magico, mind you, but most others. So, at its price, I'd say the speaker is ideal.

That's the Power Response* (Power Compression) measurement, not the Frequency Response.

* Most likely the spatially averaged in-room response. ...Its controlled (or uncontrolled) behavior's characteristic.

Regarding some of the above questions. The one previously shown as the Canton isn't the Canton.

The reason that distortion isn't shown lower than 50Hz is that at that point you're at the limitation of the chamber -- i.e., can't get accuracy.

Doug, I noticed that in all your measurements (curves); information below 50Hz is gone! ...And very little accuracy below from 100Hz to 50Hz.

Please read notes above. Can't get an accurate measurement below 50Hz for distortion, so it's cut off.

To look at all the speakers we've measured, please see www.speakermeasurements.com -- you'll see that frequency-response charts have detail to 20Hz.

You would need a huge anechoic chamber do measure down to 20Kz.
