SB Acoustics Satori MW16P-8 Measurements!

On the test bench we have the Satori MW16P-8 6.5″ mid-range from SBAcoustics. This is a very nice performing mid-woofer

Driver Measurement Methods!

November 17, 2018 Posted by gornir

 

Hi everyone,

From now on when I publish loudspeaker driver measurements, I will present it slightly different than before!

First of all I will visually present the frequency measurements and impedance differently. In the past I’ve used screen shots from the Holm Impulse and DATSv2 software, but in the future I will use LspCAD 6 Pro to visually present the frequency graphs. In that way I can e.g. show all measurements between 0 and 60 degrees in one graph. Below is an example how it will look like.

Secondly I will present and measure the Thiele Small measurements slightly different for all mid-woofers and woofers. All drivers will be burnt in for 3 hours at their resonance frequency and slightly below the x-max excursion limit of the driver. After the driver has cooled off, it’s measured in two ways.

First the driver will be measured using the “added” mass method in a horizontal position. Secondly the driver is measured using the “known” mass method in a vertical position. In this case the “known” mass is the Manufacturer’s specified Mms of the driver unit.

The driver units are always measured in pairs or more and the individual driver samples measurements will be presented as well as the average of the two drivers.

Regards

Hi Göran

“In last week I have finished my project with Satori project from your site. In attachment you can find result of this work, feel free to publish this photo on your blog if you want.
The sound is much more datailed & wider scene comparing to my Dynaudio Focus 160. My first impression was also less bass than Dynaudio, but in fact it’s not bumped on higher bass & in the same time much better on lower frequencies. Comparing in the same time both speakers I like more the Satori speakers.
Thank you again for your efforts & have a nice day.”

Best regards,
Przemek
