Genelec 8361A Review (Powered Monitor)

[Esprit]

It's very difficult to measure transient response hence why no one does it

Did you do it?
Can you post your measurements?

 

[thewas]

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.

Wow 148 pages of post….

So since this review , 8361, was posted I have read and reread most of the Genelec reviews. Slowly planning how I might convince the wife (and myself, being a penny pincher) to pull the trigger on such a purchase. But having been burnt buy buying speakers online I was not going to do that again. So every once in a while , while traveling from the quiet shores of Port Townsend WA. I would look up a Genelec dealer nearby, if that could be found. So hey I am in Vancouver for 5 days and thought why not. Upon looking I found a music store on Terminal street which carried the brand. I am not sure if it’s ok to drop names here so I can answer info questions in a private message.

Shout out to this store…..I got there thinking I would at least hear the 51’s…. So I search ahead of time and they were in stock…off i go…I get there and no 51’s….awww shucks….so I said in passing I really wanted to hear the 61’s….And the salesman / pro sound manager, Chris (my hero) said wait a minute, “this may be your lotto day, I’ll be back in a minute. A few minutes later he rolls out a dolly and says Genelec had sent this pair for an audition for a client of the music store on Terminal street. In 10 minutes VIOLA. 8361’s hooked up to a $75000 mixing board with a computer to search whatever song I wanted. He said enjoy and left me to listen.

So Chris said he wanted to keep them set up for a short time before he has to send them back. If you are near Vancouver BC and want to hear a pair I can give you the name or number if the blog police give us permission. Enjoy…

And what were your listening impressions? Do share ...

.

Well the set up was not under my control and I did ask if they were set to neutral, so the manager doubled checked and said all dip switches were set to off position.

I listened to maybe 4-6 songs of my choosing…
I could control where I sat …
It was a very big space but narrowed by some glass partial partitions but in general a ok large space.


Voices very very nice
Bass very nice
Tonality just fine.
I noticed a lacking in horn passages.
But no room eq was in play.
That’s as far as I would go understanding the variables out of my control…but it is at least off my bucket list.
