At least they're not literal garbage like the small ones.

Any measurements for the main monitors, nothing on the PMC site.

I remember knowing the old large mid 70s IMF speakers which influenced PMC so much I gather... The big 'Pro Monitor III' and TLS80 models had the usual cancellations at 120Hz or so, but IMF's (John Wright) trick was to pull thr emid and top down to match the response dip, sacrificing a little sensitivity and in the pre RSPM IV models, also risking a flat level bass rise below 100Hz (all in the early 'Choice speaker tests in 'worldradiohistory') They did a full scale loud (Hendon) brass band recording from master tape donated to us by reviewer Angus McKenzie SO well though
The thing is, PMC don't seem to do anything about the cabcellations in the mid bass, so their larger models often look absolutely terrible in the 80 - 400Hz region. Thing is, the room my big old ATCs were used in, would have 'liked' that response shape, as there was a bump-up at 120Hz in my listening seat (not there if I sat to one side), this when analogue graphic equalisers were taboo in audiophool circles such as I floated around in.
P.S. I got to know their Fact Fenestria speakers (now an 'OUCH!' inducing fifty five grand in UK money) and really liked them in a LARGE room with very high ceiling. The usual PMC hf rise wasn't an issue especially heard 4 - 5m away and in this space, the bass didn't swamp either. Surprising though, that the HFN measurements showed a bass roll-off below 80Hz, something I'd never have imagined at all

Here's a vintage response plot of the IMFs I'm banging on about above - I never found the '80 as bright as the test there shows (both tests Crown driven I believe)

They start to go up after 8k thats not bright. Its more detailed and airy. If you like to talk like that.
From a few pages ago... They're not ruler flat, but none of this roller coaster batman nonsense.
I think we disputed that above.

Such records are made with every conceivable speaker and system. That doesn't make the products great at what they do. Besides, music becomes hugely popular due to what it is, rather than its fidelity. Backstreet Boys sold not because audiophiles bought millions of their records. I know if I like some music, you can play it on a clock radio and I still would enjoy it.

Well, let's test that experience. Here is the frequency response of the PMC again:
Do you know what those massive dips do? They would significantly lower the energy of whatever notes in music hit them. That pushes them into the background. And with it, that 'detail' is lost. Precisely what I observed in my listening tests.
Harman has a training tool called "How to Listen." It plays a track and adds filters that emulate the above behavior. Trained listeners over time are easily able to detect these variations. Other people, not so much:
If you are not hearing these impairments, then you simply are not qualified to provide reliable subjective experience.

Who says? Look at the frequency response again. There is a suck out from 1 to 3 kHz. This is super important to imaging as that is where a lot of differential between left and right channels exist. The result is below average imaging, not above.
This speaker also has wider dispersion which means it will provide a more diffused spatial effect than a speaker with controlled but narrower directivity.

The rating of the PMC Result 6 will drop by 50% on Reverb thanks to Amir!! But even at a lower price, these speakers are not good at all.
LOL. I let myself be deluded by the reviews, plus I wasn't familiar with PMC' home theater offerings.
I wish he did all the reviews, honestly. Though not as detailed as what we get here, at least he measures the speakers.
Can someone enlighten me what happened here? I’m sure PMC engineers know principles of good speaker design and have access to measurement equipment and this speaker is not exactly cheap so shortcuts in design process could have been avoided or at least minimized. Yet we have this. House sound? Negligence? Something else?

Going by ears of someone with decision making power....
Which stupid as a review like this can do a lot of damage to reputation and sales.

A lot of industry still thinks we don't exist.
The older IB1S does seem to have the same sort of FR irregularity, meaning there may actually be a house sound.
The nice thing about measurements like this is that it gives you a bit of EQ guidelines to take a neutral speaker to carry more of the PMC sound signature…
two things are happening here:
1. The BBC dip is there, for some reason, even though it doesn't really help things with this speaker. Might be a house sound thing.
2. The 1/4 transmission line is doing TL things. It's sort of a fact of life that they're a real bear to design, and I've seen very few designers get them actually correct. It gets monumentally more difficult in a small box as you've got less room to make it lossy above Fb.

This is from sound on sound. I couldn't read the review, just skimmed over, totally useless. Story telling and lies just like Stereophile! Is S on S supposed to be reputable?
Under Cons they add "some might miss EQ facilities" Typical! In my experience this kind of statement at the end of a review is used by all dishonest reviewers because they know the speaker is not good. They got them for free, payed for a positive review or payed for company ads.
