PMC Result 6, has anyone listened to them or have any measurements?

[LostJack]

Does Dirac introduce latency or phase rotation? Would not be better hardware for this kind of stuff?

 

[Penelinfi]

Is it me or are you asking questions then dissing the answers if you don't like them?
Perhaps try to listen to some monitors at a shop or find ones with wide dispersion. Maybe Focal

Also if you want something for 40-120Hz, it's going to be a largish woofer, pour something with DSP or at least bass boost if using a smaller woofer.

I'm not sure what room treatments you have but using them can help ease harshness in high frequencies and also give better "detailed in frequency" , even when using near field monitors

8ms apparently. I’ve never noticed it composing and mixing but I’m not tracking live. I’m sure you could switch if off during recording it’s an issue.

Dirac Live For Studio

Correcting the frequency response of a monitoring system is one thing, but Dirac claims to correct time-domain response too. Can it possibly work?

Is not that much, very interesting. Thanks for the info. I want to try it.

 

[lowkeyoperations]

^im pretty sure they have a demo, but you will need a umik mic.

I bought a Dirac live licence and you can use it on 2 computers. So I have my Amphion One15s with Dirac in the studio and a pair of Dynaudio XD20s in the lounge room fed by a Mac mini running Dirac too.

So while it’s not super cheap, being able to run my studio and lounge room setups with the one license is pretty good value.

500 bucks in total is a low cost investment if it really works well, considering that you can use it for 2 setups. Also for the monitor I'll consider Amphion and Quested s7r. I read good stuff for both on gearspace.

@LostJack did you get any new setup? Would be interesting to hear what you ended up with.

Btw. Did you use the Neumann Kh120II speakers together with M1 + Kh 750 or did you only use the Kh120II speakers alone? I have never heard this setup, but I have also felt regarding customer service that the difference between how fast you get a reply from Genelec for example seems to be way better than Neumann. Altough I ended up getting a very long and detailed reply via instagram from Neumann once. If I wouldn't have gotten that nice reply I probably would have stopped looking at their products.

Customer service is so important, especially when it comes to very expensive and important gear.

I really wish it was possible for Amir or Erin to get hold of some of the current range of high end monitors from the traditional brands - The PMC 6-2 and ATC SCM25A / 45A. Also high end offerings from the Ampheon, PSI, Adam, Focal Trio, Present Day Productions etc. Unfortunately without the testing we just don't have the knowledge we need to make informed decisions. It's great that we have measurements from Genelec, Neumann, Kii and Dutch and Dutch though. I don't think we have any transient response measurements though. PMCs are known for being incredibly fast and punchy in their transient response.

What is ‘transient response’?

[Pete James]

What is ‘transient response’?

The attack, decay, sustain and release of a sound or waveform. Like in a compressor or subtractive synthesiser. Mostly the attack portion (how quickly the sound goes from silent to full volume) in a kick drum or a pluck sound for example

I think what Keith is getting at here is that transient response is the same thing as frequency response (magnitude and phase, to be clear, not just magnitude). If a speaker gets those right, it pretty much by definition has good transient behavior. PMCs behave about the same in that department as any other bass reflex speaker, except their low end is lumpy from the TL interference.

 

[Pete James]

I thought the time domain and frequency response are a different thing. Not that it can produce the frequencies but how and when it produces the frequencies.

Nope, all interrelated. See Fourier.

You’re probably referring to spectral decay, usually shown in a “waterfall” plot with frequency response in the X-Y axis and time in the Z axis. It shows areas in the frequency response that decay at different rates, usually due to resonances.

However! A speaker can often be dedscribed as being “fast” or having good transients simply due to emphasis in certain areas of the frequency response. The PMC house curve has emphasis in the upper bass and a lot of emphasis in the treble. This causes some listeners to perceive this as “leading edge definition”. In my experience this type of tonal balance gives speakers a dynamic “snappy” sound, what some people describe as good pace/rhythm/timing. It’s all frequency response related though.

But, if there is excessive stored energy or resonances it’s really harmful to the accuracy and enjoyment of the speaker. You can see problems here in the waterfall, impedance, step/impulse, frequency and distortion data.

At this point I'd argue anything PMC might be known for anecdotally can just be written off.

This is what i'm talking about - it's an interesting comparison of a Kali IN-8 $1000 speakers compared to Kali Audio SM8 $5000 speakers that have almost identical frequency response. You think he's talking nonsense?

 

[Artsfols]

Question -
Frequency response is measured by a tone sweep over time, constant in gain, and then the resulting time domain curve is converted to a frequency response curve using a Fourier Transform.
Hopefully I have that part correct.
So, the question is, will the resulting frequency response curve capture delays (transient response), and if so, how does that show in the frequency response curve.

Magnitude response alone will not; magnitude and phase will.

Hello!
It’s not the PMC Result 6, but here’s the CEA-2034 for the PMC 6.

Post in thread 'Neumann KH150 Review'

Aug 12, 2025

Ah, I thought it was. Neat, now there are actual measurements of a modern PMC, and it's exactly as okay as expected.

Anyway, while we’re on the subject, let me share a quick look at the CEA-2034 data for the PMC 6.
