Oh, right, you chose the Revel at random! Sure, whatevs.
I don't know why Amir didn't measure the port seperately, maybe that's something he's only started doing more recently. The port distortion is very well controlled in the Revel, but the raggedness in the THD between 1 and 2 kHZ is likely port generated. (We can't tell without a port measurement.)
Anyway, it's the phase shift issue and subwoofer integration that's my main complaint with ported bookshelf speakers.
And Amir hasn't measured any sealed ones, because there are so very few to measure.
Okay I admit. It was not entirely at random because the thesis was well constructed. Then I had to take a well constructed.It would have been rather pointless to take a poorly constructed.
Now it does not matter what I took, because it reportedly applied to every ported. Incidentally, all speakers, regardless of construction type, create distortion. The question is just what is preferable?
A poorly constructed ported has probably all heard at some point. When it clearly sounds audible bad from the port. But they are not interesting to consider.
There are not that many sealed to test. Why do you think this is the case?Of the ten top speakers Amir tested, one is closed, by the way
In any case, it is interesting that Amir
nowadays measures the port itself.
Near-field response shows very good control of cabinet / port resonances which we almost always find to be a problem with front-ported speakers.
This is a review and detailed measurements of the Focal Solo6 Be studio monitor (powered active speaker). It is on kind loan from a member and costs US $1,499 each. Unlike most studio monitors that have industrial looks, the Solo6 Be comes across as a high-end home speaker with its nice wood...

Near-field response? Microphone placed how? The new way to measure compared to when Amir did not do so when he measured distortion on ported speakers before, is?
Has Amir performed a Near-field response on a sealed speaker?
How many sealed subwoofers has Amir tested, measured?
Speaking of phase. I thought this was interesting.
Does Phase Distortion / Shift Matter in Audio? (no *)
