Genelec 8361A Review (Powered Monitor)

[AudioJester]

@Impossible not sure why you are getting so emotional, relax - just discussing speakers. Lots of members here who I have great respect for prefer other speakers over Genelec - nothing incorrect about that. The reverse applies to. Personal preference plays a huge part even with equally well measuring speakers.

If you sorted out the frequency response issue, can you post the final measurement? What was the issue that caused the wonky curve?

One final time - why only 1 speaker??

Can you provide an example of the transient response measurement you repeatedly ask for? If it can be done with REW etc. , I might be able to do it.

 

[Impossible]

I am relaxed. But no point talking openly in a palce where people only want to hear 1 side. I'll just discuss my experience somewhere more neutral.

That was my centre channel. Which was a placement issue. After talking to genelec who were great, doing a near field measuments it was clear that it wasn't the speaker. Again not the same thing I'm talking about here.

It's very difficult to measure transient response hence why no one does it. But you would need to measure something like the overshoot and undershot, speed/time from rest to end and back to rest at different frequencys and spl. Way over my head.
There is a thread discussing how you could do it.

Like I said this is the wrong place to say anything negative about 8361a.

I did trouble shoot it with genelec and resolved that issue. This is not what I had a problem with, it was with complex transients. Again not only, in my set up but 2 others. And in the same setup comparing with other speakers over a long period.

This is my last post here as you can not conclude it unless you measure the transient response else your just saying what ever will make you feel right.

OK, I see. So you just making things up. You clearly have no idea what transient response is. This has nothing to do with Genelec, with fans of Genelec, or anything else. Or KEF. Or any other speaker people may or may not like. My personal preference, there are other speakers I like more. But I can say I don't care for nonsense.

So help you guys sleep better: the 8361a's are the best speakers in the world and can not be improved upon. They are perfect.

I doubt anybody is losing sleep over this. Your sarcasm is noted.

Did you do it?
Can you post your measurements?

Transient response and resonance are different things. You would need to measure the transient response of both speakers to see which performed better in this area.

As I wrote above such problem if exist, they would be visible also in the frequency response, to quote Dr. Toole:

The loudspeaker is, or should be, fully characterized by anechoic measurements. These include the time domain (transients). If the recording is an accurate rendering of the music, good loudspeakers will reproduce the music with sustained tones and transients intact. Loudspeaker transducers are minimum-phase devices so a flat smooth anechoic frequency response indicates a flawless transient response (within the frequency range of each transducer).

I know what it is. But I never spent time with the math side of it like transfer functions and such.

Obviously, as otherwise you would know that above is just the step response (which is included / can be calculated from the complex frequency response) and that such typical overshoot corresponds mainly to the bass region and is a very poor way to visualise loudspeaker issues.

There is thread here:

Measuring transient response?

I was wondering how it would be possible to measure the transient response of a loudspeaker using a measurement microphone (e.g. UMIK-1) and a software (e.g. REW) Here is the idea I came up with: I have generated 1ms sine tones at various frequencies at a certain volume and the same at a volume...

There was a good paper but I can not find it right now.

A while ago, I did ask Erin from Erin's audio corner and he said there is and there isn't a way to measure it.

His final comment and conclusion about the mids after trying them the final time "They probably are a little hot through the upper mids compared to many monitors".

OK this is the last post...

Seeing as we're in the domain of guessing, I'd bet that your problems come from poor set-up, as none of the features that you imagine relate to my set-up and experience.

Either way, I hope you are happy with your speakers and let's see if this is in fact your "last post"!.

Enjoy

Where's the logic here, do you have the measurements/data of the transient response to say one performs better in this area over other speakers?
Are you also not guessing?

Answered in post #2.

"Now you are wasting your time. The transient or impulse response can be calculated from the FR sweep in REW."

And he also answers your question about not understanding the math.

The comment from @Blumlein 88 about square waves as one way of demonstrating that talking the frequency response measurement also gets you the transient response.

"Ray was using the square wave to show you get the same thing either way."

End of day, your measurements are really puzzling, and I would certainly not like to a speaker with even half-bad the response you show. It looks like the microphone was blocked. Or GLM completely malfunctioned, if so, no defense on Genelec. Which would certainly lead to a bad sounding result.

Those measuments were a placement issue and were resolved so not sure why you keep citing them.

I get it, this is the 8361a thread and in this universe nothing can be better. Not kefs not, the beryllium midrange in the tad's or anything.
Even without the data you already know.

We get it
You don't like the 8361
There's no need for sarcasm

Can you share the corrected measurements of your centre speaker?

I think your approaching this the wrong way. Its ok not to like a speaker, or prefer another. But then you repeatedly seem to claim a underlying performance/measurement issue with absolutely no evidence! Do you see the issue?

You even show you have no understanding of what transient response is? Or how it correlates to what you hear.

But if all the audio engineers and experts have missed something you have found - I am all ears

 

[Esprit]

You are in a loop.

 

[kma100]

I don't have either the KEF or the Genelec but sounds like there are two issues, and it wasn't clear initially what was resolved. It does appear that the "dip" issue was fixed, is that correct @Impossible? Your other concern is related to the transient response. No point of view there but part of the back-and-forth is related to misunderstanding...it came across that "Genelec is bad" which is why you are getting pushback.

Hi everyone, I have a pair of unity audio the boulders mk2 that I think are beautiful, do you think switching to the genelec 8361a would bring me any advantages? I listen to various genres of music and produce electronic club music. Thanks

If there is a difference, it will be in the listening distance, in my opinion.

 

[Esprit]

would bring me any advantages?

Probably the biggest advantage is GLM.
The advice is always the same: listen with your ears.
P.S. I listened to the Boulders many years ago and I liked them.
