Genelec 8351B Review (Studio Monitor)

[Kain]

So many variables, but roughly speaking, it should cross 100db before any clipping. It's spec'd at 113 and that crossover would relieve a lot of the power draw.

Genelec is fairly close on volume measurement in my experience. I have a 8361a that is rates 118db and full range it hits 100-105 at 5 feet with bass-heavy content.

Thanks.

Roughly speaking, how loud could the 8361A get at 6 feet when crossed over at 80 Hz?

 

[Mort]

Actually, not much louder 3-5db. They share the same tweeter and have the same wattage on the midrange. The 8361a will be 10db or more louder with full range bass heavy content, but crossed they aren't that much different.

This is why the 8351b is so popular with a sub.

On the Genelec website, they spec the short-term max SPL for the 8351B from 100 Hz to 3 kHz which they say is 113 dB. For the 8361A, they spec the short-term max SPL as 118 dB but don't state between what frequencies. Is it also 100 Hz to 3 kHz for the 8361A even though they don't say so?

8351B's SPL specs as follows:

8361A's SPL specs are as follows:

This man's signature opening rhythm and melody are of the familiar Genelec super super quality. All music, by the way, sounds almost the same in our living room, but louder. There's no need to be ashamed of the sound quality if you have the highest sound quality a person can make.

I think the first videos about Genelecs on You Tube show how they should be played properly in a small space.

I don't think this opening theme is the flat sound that is typically played everywhere from Genelecs. It's the sound of pleasure now.

Why did your ask me if you are going to repost the website?

I'm giving you real numbers in a real room with bass heavy music as I said.

I didn't mean to "counter" your post, just asking if the short-term max SPL specs Genelec states for the 8351B and 8361A are both 100 Hz to 3 kHz because they don't say so on the 8361A page like they do on the 8351B page.

 

[Mort]

Yeah I don't know. I always assume manufacturers specifications, even genelec, are calculated optimistically or under certain conditions.

Can I ask what exactly are you trying to reach or accomplish?

Just curious.

 

[Mort]

Yeah. They go loud.

I'm using a 8361a crossed at 75 hz which is a huge waste over the 8451b. Effectively I have a 700w Amp driving 75-300hz range which will never be used entirely.

 

[Sokel]

Just curious.

You should ask the right questions then.
SPL varies widely depending weighting.

For real-world applications I would use (C) weighting for average and max and (Z) wighting for peaks.

You can see the differences at this example.

Below is one of Amir's reference songs,"Fading Sun" by Terje Isungset first measured with A weighting and then with C weighting.
Level is the exact same,I touched nothing during the recordings:

(A) weighting

(C) weighting

So, specs have to be carefully interpreted each time.

Thanks for the reply.

How many "weightings" are there are what is the difference between each?

Yes, all of our full range speakers share the same averaging frequency range for the short-term max SPL spec. It is simply an error that the footnote is missing on 8361A page. We will correct it.

 

[Sokel]

Thanks for the reply.

You can see here:

Z-weighting is essentially flat so it's used for peaks.
For max and average though C makes more sense as it shows low bass too.

@Mort

Just a quick question regarding SPL:

Say my room is 12 feet long x 10 feet wide x 9.5 feet high. I have the 8361A as LCR which will be around 6-7 feet away from the listening position. All other positions (surrounds and overheads) will be the 8351B which will be around 4-5 feet away for the surrounds and maybe around 6-7 feet away for the overheads. All speakers are crossed over at 80 Hz to subwoofers. Do you think I will have all the SPL I will ever need? I listen very loud when given the chance.

The short answer is yes. In my testing, 8361a alone can get 95db at 6-7 feet alone and still have a little room even with bass heavy content. I listen at 95 avg Dba for less than two hours a week. It's very loud.

Honestly, I have found their subs to be the limiting factor when crossed like that. You should definitely get 2x 7370a and strongly consider the 7380a although you may not have room, that 170lb thing is massive.

While it might seem a little crazy for that small room I mentioned in my post, I've planned a 9.2.6 setup with 8361A as LCR, 8351B for all other locations, and two 7382A subwoofers (one under the TV and one opposite it at the middle of the back wall). So, when crossed at 80 Hz, SPL/clipping won't be an issue even at very high volumes? I really hope that is the case.

 

[Mort]

Ha, you will have no problem. That's a massive setup for that space. Good for you.
