PMC result6 Monitor Review

[Wesseling Audio Lab]

After I finished 2 years of college electronics in I worked for Audiosphere research for 2 months assembling speakers. These speakers were total garbage and they were producing them in large numbers 5 days a week..
FWIW, I just came across this below. I'm not critical of the person at all but its an example of how the lack of experience with home audio quality is required for the success of a speaker company. Add in the dishonest reviewers and the companies are in a better situation for continued financial success.

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

Actually he was talking about Result6 not having any options of FR correction at all. I'm not mentioning deeper approach of on-monitor basic room correction that's rather normal nowadays.

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.

I subscribed to SOS for years, I never saw a negative review there, however their positive bias towards the UK companies is thought the roof even by their standards. They're obviously an UK magazine

 

[Rahan]

I already thought PMC was way overpriced based on its specs. Now that we have measurments, I can't see any reason why anyone would want to buy one of these. It reminds me of the horrible measurements of Wilson Audio.... The more you pay, the worse it sounds. Great business!

 

[ssashton]

I think it could be argued that the dip in bass around 100hz - 300hz IS part of PMC house sound since it is a result of the transmission line design having a second harmonic that is out of phase with the main driver and all PMC speakers are like that.

The extended but weak low bass can work well in small UK brick built rooms that provide strong boundary reinforcement. May be desirable in a passive speakers that lacks tone adjustment.

The rest of the response irregularities are a bit embarrassing...

 

[Puddingbuks]

No need to further investigate, this speaker and brand is just not good.

PMC engineers, if you read this you should be ashamed.

Does the PMC result6 lack a waveguide, just like JBL Control 1 Pro and B&W 607 S2?
607 S2 has a similar beamwidth narrowing issue at the crossover frequency.

Are there any good reasons to omit it? I don't think there are good reasons to do so.

JBL LSR305P MKii and Control 1 Pro Monitors Review

This is a review and detailed measurements of the JBL 305P Mark ii powered studio monitor and Control 1 Pro budget passive monitor. I purchased the 305P Pro Mark ii when it first came out and it currently sells for US $147.50 from Amazon including Prime shipping. This is the price for one so...

Bowers & Wilkins 607 S2 Anniversary Edition Review

This is a review and detailed measurements of the B&W 607 S2 Anniversary Edition. It was kindly sent to me by a member and costs US $700 through their various dealers. The 607 S2 comes in different color. My same was in black: Disappointing to see no attempt at directivity control with a...

From amir's comment on JBL Control 1 Pro:

As noted, while you may be tempted, in general you can NOT EQ and bring up the missing midrange. The problem is that EQ sits in front of the speaker. It will impact both direct and indirect sound equally. Here, our problem is that our indirect sound has a problem so EQ in general cannot fix it. I should note that a double blind study of room EQ system did find some improvement can be made here subjectivity but it is best to avoid speaker with such dips. It is quite common when a large woofer is mated to a small tweeter with no wave guide. The woofer gets too directional before it hands off the signal to tweeter which causes off-axis response to suffer.

PMC engineers, if you read this you should be ashamed.

They have engineers?

[DSJR]

Yes Keith, I believe they do and do what they do for a reason I'm certain Maybe they see their (to me) iffy domestic models as competing with B&W, so adjust them accordingly. I gather that active amp packs can be boiught now for under two grand UK money for all or most of the '20' series. I'd like to see these tested myself

Now, this model is supposedly derived from another previous one from what, fifteen years ago? If so, in the days before waveguides became commonplace and less people were picking over response anomalies (the subjective-only era is only just starting to wane I'd suggest).



These do, as I think I said earlier, have a LS3/5A-esue response to them - and you know how revered they still are in some audiophile circles, even the bad mid 80s ones with an extra 4dB tacked onto the 1.5kHz region until the re-design in the late 80s...

 

[Mnyb]

Wonder if they have trapped themselves in thier own legacy ?One of their core ip is transmission line speakers over all other concerns

TL is probably a dead end with todays driver and smaller speakers?

 

[ssashton]

Thing is, they were one of the first to use a waveguide tweeter in the AML1 speaker, plus molded baffle with large rounded edges for reduced diffraction. I don't understand why they have not followed that design ethos. Its like the designer is a totally different person who now uses a simulation from datasheet curves and says 'that'll do'.

 

[Alegretti]

I listened all the graphs! You nicely put them in order from the best to worst sounding lol.
View attachment 430261Almost 60-20000 +-3 dB but V-tune. Will please a lot of people with clean sound! However, those two hi-mid peaks I ignored might be audible. I hate B&W.
View attachment 430262 Again +-3 dB whole spectrum, unjokingly good HF
No comments on MA, simply a stupid speaker for that price
View attachment 430263 Simply awful tune and heavily colored

The problem is the 6dB delta between 1 and 2 octaves.

 

[dfuller]

Does the PMC result6 lack a waveguide, just like JBL Control 1 Pro and B&W 607 S2?

Yes. Well, except in the sense that a flat baffle itself is a waveguide.

Are there any good reasons to omit it? I don't think there are good reasons to do so.

They're an absolute bear to design well - if you're not careful they can cause all kinds of diffraction weirdness. Neumann and Genelec et al use considerable computer simulation (and before that were doing iterative designs). I will note that PMC do use waveguides on their higher end designs. Like so on the MB3A:

From amir's comment on JBL Control 1 Pro:

Yes, generally you'll need to instead focus on absorbing early reflections to make EQ more viable. You'd probably want to do this anyway - the quite wide dispersion of this speaker from 2-9k could make it sound quite bright in a typically reflective room.

My expectation is that the calculus for a speaker used in a room with largely absorbed ER will focus less on perfect off-axis evenness and more on axial linearity - though this PMC clearly kind of fails at that too, so I'm kind of out of ideas on that one.

 

[Marc v E]

I listened to these years ago and decided upon hearing them that studio sound was not for me. Doesn't surprise me at all they measure so bad.

Funny thing is this speaker convinced me to buy B&O. Hadn't heard of Genelec then. Would have been a whole other outcome.

 

[Marc v E]

I feel embarrassed to be British at this point. Apart from KEF every other British brand seems to have just gone and dived into the deep end. Linn and NEAT and Naim were already swimming there. But B&W, Tannoy, PMC, ATC, what have you sold your souls for?

I can kind of relate: every time I see an old favourite brand before I read 2 graphs, I'm thinking: " Another dream shattered ". Godawful measurements from those well known brands thoroughly recommended by what hifi and others.

Whats crazy is that in music production groups any time you slander PMC or ATC, its like you're setting yourself up for a beatdown

ATC are not anywhere near this. They have their own issues (lack of meaningful attempts at pattern control, chiefly) but they're not trying to reinvent the wheel and use a big box design in a small one, and their axial response is miles better.

I've matched scaling and overlaid the on-axis behavior for the 25A Mk1 (via Resolution magazine) to the Result6 - it's really not anywhere near it. The 25A's pretty much matching spec (+/-2dB) for axial response, minus some (probably inaudible) high frequency hash that almost assuredly isn't there on the Mk2 given the far better tweeter.

I think what’s most of you guys missing here is a real life use case perspective. These speakers are an entry level studio monitors, not hifi speakers for home listening. And when working in audio production we usually have desks or consoles in front of speakers, you know? And these desks give us reflections. In my case for example I have a 4db peak at 200-300hz and a 3db dip at around 800-1000hz, then another peak at 3k because of the desk reflections. It’s quite a common pattern if you sit at 1 meter in front of the speakers. So in my case this kind of frequency response would give me much better results than a flat one.
Wide dispersion in high frequencies? Great as well, because when using a lot of treatment to fix the bass problems you inevitably overdamp the highs (considering you’re not in 5 million dollar studio, but these are entry level speakers, remember?). I know this for sure, because my focals have similar dispersion pattern and it really helps keeping the reflections more even.

So, I’m not saying these PMCs are ideal, I actually find them a bit overpriced. But in some situations they can be quite preferable

"Entry level"

I know actual entry level speakers that beat the breaks off of this.

Ask me how I know this

 

[Bubblegamma]

Good for you. Did you work on both of them?
