I have conducted a few indoor measurements of the KEF Q350 that I'll share. I'm aware the speaker has been measured by Amir and Stereophile, but wanted to measure it myself after I set a pair up at work where we very dissapointed by the sound quality.
First an on-axis measurement at 20 cm distance and placed on a 1 m tall stand.
1/48 Oct. smoothing:
1/6 Oct. smoothing:
At 40 cm distance, we can see the room starts to contribute more.
1/48 Oct. smoothing:
The directivity measurements below was conducted at a 40 cm distance on-axis. There's no gating used here, and the room defintely starts to interfere with the measurements. So keep that in mind.
Horizontal polar out to 90°: Normalized.
Horizontal polar out to 150°. Normalized.
Vertical polar to 90°. Normalized.
Vertical polar to 150°. Normalized.
In the next post I'll share a few more measurements and some comparisons with other speakers.
