Bought genelec 7370, now sad.

[dj94030]

Was thinking i can use it to plug a null in 50-70hz area but subwoofer is localizable even with 60hz glm crossover.
Woop woop in left ear. It's less dramatic if i run mains full range.
I know that the result is good but i clearly hear the whoop whoop and can't tolerate it. Is it psychological? Sub is on the left side, almost under the speaker.
Phase is at 180. With phase at zero i get a very narrow deep null at crossover frequency. Attached as well. Is it related maybe? Shall i cross higher and set phase to zero?
Shall i just ignore then 50-70hz thing, and enjoy my bass and return the huge freight box? It's not like something was lacking before, but its definitely nicer now lol. Can see how second box will be great, but can't at this stage. Also can't center the single sub.
p.s. i tried other settings, including automatic glm cal and i can always hear the sub singing in my ear. Even if it plays solo with 50hz cross.

What i'm trying to fix:

Result:

null with uninverted phase:

Can't you move it to the middle? In damped enough rooms it's pretty obvious that the sound is not coming from the center, this is the reason I would go with two smaller subs and even try true stereo

 

[dj94030]

I can't, it's a computer system and desk is into the wall, i dont want to move it 1 meter into the room. SBIR also. Second sub is too big, too expensive, also i live in rental.

If the sub is in a very similar location to a speaker, it is going to interact with the room in a very similar way, resulting in a dip in a very similar place.

You might try placing the sub in a very different location from your main speakers.

Can't you return it? The price for one 7370 is pretty close to two 7360, both have the same response, 7370 is just 100W more powerful, IMO 2 x 10" and 600W is better deal than 1x12" at 400W

It's freight shipping, huge pain in the ass and i have to pay huge fee for shipping. I used to have 2 10" subs with other monitors(5" tho) and was never happy. So that's why i wanted the big one. But seems like return is the only option oof.

- What is your main speaker?
- Are you using GLM?

8351b, yes.
played more with crossovers and phase, i still hear it whoop whooping from 1 side. Gonna try some more and then most likely return and maybe get 2 smaller ones.

Ahh… I went through a similar experience. I am running Neumann with one non-Neumann sub, crossed at 80.

Sub originally placed at front right; and yes, localizable and that wierd bass whoop whoop effect to the right.

I solved it by moving the sub to the front center. Unfortunately at the front center the resulting FR isn’t that smooth in the bass region, a few dips here and there (bumps can be tamed by EQ). Thankfully the dips were high Q (very narrow) and not audible to my ears.

Currently my mains are almost into the wall. On computer desk. I dont want to move it all 1 meter into the room

Doesn't the Genelec system have internal DSP?

I have a small SVS micro subwoofer about the same size in a tiny office where all the speakers and the sub are against walls.

DiracLive makes it sound great without much work, and glorious with much work.

If you’re unable to move the sub to the front center, i can suggest this long-shot/wild idea — have your subwoofer cone fire sideways towards the center (instead of front-back).

(Yes, I know that bass freq is supposed to be omnidirectional… it’s a long shot experiment…)

Have you considered to place the sub above the monitors, hanging from ceiling or wall and firing front or down?

Rental place. I'll return it and get 2 small ones if situation allows. In case of relocation shipping things by courier/post is one thing, but having to deal with pallets and freight is another thing. And i will probably never be able to sell it locally if something.
Nice sub tho.
Very.

 

[HiMu]

Turn the sub around so that the element is facing the front wall, needs minimum clearance of 10cm/4" and port has to have 7.5cm/3". That can reduce the dip quite significantly.
Also, take a calibration measurement from 20-30cm higher, if the dip gets better, it's listening position related.

 

[Joachim Herbert]

I have KH120 on the desk and a KH750 below, crossed at 80 Hz and firing sideways. This allowed for central placement of sub, as the woofer will not come in touch with my feet. Neumann sub is closed, though. Never bothered to measure that setup as it sounds sublime.

I actually would not bother about sharp dips.

Yours is about 1/8 volume wise. I'm looking now at the 10" genelecs and they are half weight and quite a bit smaller. Should've bought them instead

Do you hear the issue with actual music or only test tones? Test tones are useful, but chasing this down my net you a system you are less happy with making other compromises.

I’m also curious, can you place the sub in the rear corner of the room? That’s powerful enough to energize the whole room without being so close, and this may net you a more even response at the listening position.

 

[dj94030]

Actual music..
And rear corner is still localizable and can't put in rear center. Not sure why i hear it so well, its crossed at 60hz.

It may not be practical, but can you experiment with the other rear corner to observe the results? I’m unsure why you would be experiencing this. It’s also worth checking your hearing if your left ear is dominant.
