Are my Genesimmons' in the right place?

Are my Genesimmons' in the right place?

Youngling Posts: 5 Join Date: 4/3/09 Recent Posts
Because of the prettier sex of our household I had to place my minimalistic speakerset in quite an uncomfortable location. The subwoofer had to be located into a shelf, and I think the shelf is somehow dampening the bass when listened to from the default listening position. But when I move around the room I can sense the SW getting much more gain.
Should I start modding the shelf (removing the backside panel) or should the SW be located in a different place (well, obviously it should, but the lady doesn't like the idea)?
I'm quite green in this whole scene, so be gentle. :mrgreen:



The shelf is <10 cm from the wall behind, should it be closer/farther to the wall?
The listening chair is missing from the picture, so don't wonder about the 6010's located so close to each other..

BTW, I've heard lots of comments from my friends that the 5040A looks like a vacuum cleaner.. :oops:

Thanks for your post. The position of the 5040A relative to the walls and other boundaries is the critical factor in your typical case.

First, it would be better - for better LF coupling - if the sub would be placed directly on the floor and not on the shelf floor which is transparent at LF. However, this looks like hard to achieve in your setup.

Second, the wall behind the shelves seems to be some sort of false wall (with a kitchen behind it). As of its construction, it probably does not couple with the LF that well, so in that way the sub is probably located in the middle of the room acoustically.

The sub should be in any case right against the wall behind the screen, so leave the shelf as close as possible from that wall. If you have noticed that LF is good/better as you move around, it clearly indicates that there are some LF pressure minima in the main seating location and that the sub is located in the acoustic middle of the room as said above. As you probably cannot move much your seat, try to move the sub instead. Try to locate it in either the left or right shelf box. This might change drastically the LF reproduction in the room - and the look slightly too. Worth the try though!

For your 6010A, it would be advisable to place them slightly higher - say mid way up of your screen. Lifting the speakers up will help to achieve better sound quality as the desktop reflection will diminish. You could also try to enable the desktop control dip if you cannot lift them up. Whatever elegant solution you find with your better half to raise the speakers will be welcomed!

Our 5040A is indeed moving dust! ...but not yet sucking dust.... maybe we should think about that too :)

Hope this is helpful.

Hi i have a room 25 feet in length ,10 feet in width & 9 feet in height. i have made arrangemments to listen to my speakers across the room (width) my listening distance will be approx 8- 9 feet to the speakers. it is a open room with a sliding window & 3 doors. will 2 of 8020 speakers & 7050 subwoofer be adequate for this room.
will the sound be as good in this Open room as in a Studio where the Genelecs perform exceedingly well?

Hi,

Thanks for your post and questions. To be able to provide a clear and precise answer, I need to ask you some further questions on your setup.

- First, as you mention a studio control room setup with 8020A, is the setup you are now talking about a home studio type of setup, or is this a home stereo setup? Please precise your application.
- I have understood that the front-back orientation of your setup is about 8-9 feet parallel to the 10 feet dimension of your room. Which means that the longer dimension of your room (25 feet) is placed on either side of your setup? Please, could you confirm this is indeed the orientation of your setup?
- It is an open room you say; where is the opening, along which wall? Where are the 3 doors and the sliding window relative to your setup?

The quality of the audio reproduction in your room is closely linked to the acoustic of that room and the placement and proper adjustment of the entire loudspeaker setup. Thanks in advance for your additional infos.

Best regards,

Please excuse me for the amateur diagram,just wanted to convey my thoughts.
1.the setup will be for home stereo setup.it is the living room in my house.
2.length of room is 25 feet ,width 10 feet.
3.there is a sliding window on extreme right of the room(diagram)
4.centre of seating & placement of both 8020 speakers is in form of a equilateral triangle.
5.height of speakers is set at 3.5 feet from ground level.
my main concern was as in a demonstration room ,all the parameters are acoustically designed including soundproof door,absorbent walls etc,the effect of the Genelecs is impeccable in this Controlled enviornment.
but as in my house with the given dimensions & layout will the both 8020 speakers & 7050 subwoofer perform as good as they would in a listening studio?
i feel the sound quality may drop.please clarify my doubt.
Thanks.

Hello,

Thanks for your replies. Indeed, a picture would be most helpful. When you post a reply, in the lower part of the editor window (below save, preview, submit buttons) there is a tab called - Upload attachment. You can then browse your computer and upload pictures. Then you need to insert them in your text by placing your cursor in the right location and click - insert in line with text.

Hope it is clear.

Hello,

Thanks for your additional information and the picture diagram. The home-type rectangular room shape is always a difficult one to find the optimum placement for an audio system. Also, the acoustic of the room is certainly more critical than the one of a purpose built demo room, but this does not mean that you cannot find a suitable placement for your system which will provide quality audio reproduction.


As you have set the orientation of the listening along the 10 feet axis, here are a set of guidelines to find a suitable placement for your system.
- Avoid placing the listening position exactly in the middle of the 25 feet dimension.
- Avoid placing any of the 8020As or 7050B subwoofer exactly in the middle or on the quarter-length of the 25 feet dimension.
- The subwoofer does not need to be placed in the middle of the two 8020As, it can be offset slightly which might improve quite a bit the low-end reproduction in the room. The 7050B should be placed on the floor and against the wall (see our Quick Setup Guide for more pictures on this issue).
- The 8020A should be placed on stand with the acoustic axis facing the listening positon (head height) with a 60 degree angle between the left and right speaker.
- Moving the stereo setup away from the large bay window is a good idea.
- Try to have furniture, carpet, curtains, shelves, etc in the room so that the reverberation is not too high which might disturb the audio reproduction.
- Consult also our on-line Quick Setup Guides (http://www.genelec.com/catalogues-broch ... up-guides/) for 8020A and 7050B which provide additional infos.

Hope this will be helpful.

Hi Christophe Anet

Thanks for your reply,it was very informative.it goes along with the placement i have planned & the inputs from a Engineer who has visited the place.Will be using Tiltable wall brackets (Genelec)to achive a downward & inward tilt towards the centre of the seating arrangement for the perfect imaging.
looking forward to listening some great music.
Thanks & Regards
