The Focal Shape series is interesting because it has passive radiators where all of its competitors have ports.. it'd be cool to see a different approach to boosting bass in the size class.
It's not uninteresting, but the Focals are a very unremarkable example to see that (
https://www.soundandrecording.de/equipment/focal-shape-65-studiomonitore-im-test/) as linear distorsion is way too great for that price.
But the nearfield passive radiator response shows a very smooth decay, that only very well made ports can attain: browsing SAR's monitor reviews like the JBL 705p, Mackie XR824, Genelec 8350A and S360 shows that only the S360 is as clean/cleaner; the 8350A isn't, but the 400 Hz port artifact is low enough in amplitude to not be too grave (it actually fills a dip in the woofer response).
8030/KH80 bass performance only look good on paper and both are very disappointing in practice.
That's a singular opinion, I haven't heard of anybody (including me) having such problem with these.
IMD test would have been really interesting. Is the Dynaudio better (because of HPF) or worse (because of crossover at 5khz)? etc.
Yes and no. The fact that the LYD-5 has basically an equal amount of harmonic distorsion at 86 dB that the Genelec has at 96 dB
while having this low cut filter says it all;
10 dB headroom difference with the same woofer size, mate, that's just not in the same class. The Genelec also has a bass roll-off dip switch that brings it to 59 Hz F6, so you don't even need to bring out the software filters to get a more comparable LF extension.
But it'd be interesting to see the result of the multitone measurement with and without the filter (basically emulate a subwoofer presence).
