Brilliant! KEF Blades were superb when I auditioned them
Yes, based on what I learned whilst changing balance by moving microphones whilst making recordings and not documented indeed.Good for you. But this subjective, not documented, personal experience.
I will have to assume that you haven’t read the book mentioned, especially chapter 8.2.8.
I'm askiing myself the same question.This looks to be an amazing speaker. Unfortunately its waaaaayyy to big for my living room. Any chance of a F226be review? Finding revel speakers for decent prices in the EU(NL) is quite hard. The markup is significant and there are little to no sales unfortunately.
Interestingly, the measurements show little ripples in frequency response throughout the midrange and low-to-mid treble, just like Stereophile's measurements of the F228Be. here
They're probably far too small to be audible. But they're puzzling nonetheless. Anybody have any explanations for them?
The book I have only goes to chapter 8.2.2
Different book, sorry.

Suggest dont be so negative look up F3 or F6 low end roll off for floorstanders and instead trust Revel designers know what they are doing based their research on subject so probably deserve a user smile instead of those negative user notes, reason is for example for book shelve category the designer cant know whatever distance to any or the closets boundary will be but actual for floorstanders they absolute know precise the distances to nearest boundary is the floor and can calculate a most reasonable roll off then that would sound pretty realistic right without using subwoofers.
In below visual there is calculated floor boundary gain for woofer most close to the floor then middle woofer then upper woofer and finaly some pressurerization room gain with 50% leakage for a room having longest room dimension of 20 feet, think animation suggest for the clinic anechoic F328Be curve there will be good 30Hz low end reach covered before more room boundary's probably at longer distances and nasty room interference adds their finale signature to acoustics, heights of woofers relative to floor is not precise but a reasonable eye balled estimation..

@BYRTT, I may be mistaken, but it seems to me that that what you're doing there is calculating a speaker/floor contribution for each woofer and then adding the sum of those contributions to the combined response for all three.
The problem is, regardless of the number of woofers on the baffle, the floor bounce can't contribute more than a 6dB boost to the summed response.
Yet it appears that your calculations there show the floor bounce (minus theoretical room pressurisation gain) is contributing up to 9dB, which is impossible.
Perhaps I've misunderstood what you're doing, of course?
Erin has one.
And yes it’s very good. the review (or the speaker; you decide)

That's not the case with subs either.
The other thing with subs is too much bass. When watching movies I am game for that. But with music it can get too much with some music, and not with others. Hooked up a sub to our living room TV system and had to disconnect it after a few hours since the commercials had the most bass!
Not saying don't use a sub but you are in for a lot of work to get them to work well.

I think there are some complexities with the port measurements and the combined plot. @amirm notated the upper port was tested. There are two and they may/are tuned to different frequencies and/or operating from different cavities, I don't know.
I wouldn't go on the combined plot, I would note the subjective comments in this case.
Subjectively, when I have built speakers with 2 woofers, I found I like the bass better even if I might be sacrificing a few hertz of low end.
Since this is a tall speaker, you may want to tilt it down a bit if you are sitting too close to it.
So, the family is like 226, 228, and then 328? I guess the tweeter and the midrange are the same so the difference is all in the amount of wub wub.

The 226 would have the benefit of being shorter.
