Here is an extract of BL50 technical guide (available on the B&O website):   Appendix 1: Recommendations for Critical Listening 14.1 Loudspeaker Configuration The Beolab 50 provides you with an extremely wide range of parameters that can be used to adjust the timbral and spatial presentation of your recordings for various listening rooms, loudspeaker placements and listening positions. However, it is always best to start with an optimal configuration in your listening room. First consider the relationship between the loudspeakers and the listening position itself. The two loudspeakers and the listening position should be the three corners of an equilateral triangle. This means that the distance from each loudspeaker to the listening position should be the same as the distance between each loudspeaker. This also means that the loudspeakers will be 30◦ away from the front, centre location, directly in front of the listening position. Figure 14.1: The centre of the sound beam in the vertical plane is level with the top edge of the acoustic lens when raised (at a height of 108.7 cm from the floor). Secondly, the two loudspeakers should be “toed-in” by 30◦. This means that they should be slightly rotated so that they are both facing the listening position. This is shown in Figure 14.2. Figure 14.2: A “perfect” loudspeaker configuration with Beolab 50’s. Both loudspeakers are aimed at the listening position. The distance from the listening position to each loudspeaker is the same as the distance between the two loudspeakers. If possible, the height of the listening chair should be set so that the listener’s ears are level with the centre of the vertical beam, shown in Figure 14.1. The next consideration is symmetry within your listening room. It is commonly recognised that the best stereo imaging will be achieved if the listening configuration (the triangle formed with the listener and the two loudspeakers) is placed in left–right centre of the room. Therefore, the side walls will both be the same distance from the listening position, and the loudspeakers will have the same distance to its adjacent walls. This is to say that the distance from the left loudspeaker to the left wall is the same as the distance between the right loudspeaker and the right wall. The distance to the front wall (behind the loudspeakers) should be the same for both loudspeakers, but certainly does not have to be the same as the distance to the side walls. Figure 14.3: An optimal placement for the loudspeakers with respect to adjacent walls. Note that the distance between each loudspeaker and its closest side wall are identical, and that the distances from the loudspeakers to the front wall are also matched. Figure 14.4: An less-optimal placement for the loudspeakers with respect to adjacent walls. Note that the distances from the loudspeakers to the front wall are matched , however, the distance between each loudspeaker and its closest side wall are not identical. Figure 14.5: Another example of a lessoptimal placement for the loudspeakers with respect to adjacent walls. The distances from the loudspeakers to the front wall are matched, however, the right loudspeaker and lacks a side wall nearby. 39

I can't find anything on the archived forums about BeoVox 3000 placement, but there are a couple of threads about the larger BeoVox 5000s that may be of use: Personally I would try to position with the Beovox's tweeters at approx listening (ear?) height and conduct some experimentation with the distance from the corners, whilst aiming for a approx equilateral triangle between listening position and the two speakers.  

That very much depends on how you want to use these speakers? Are they connected to a tv, are they in a smallish room…a dining room or in the living room with couches and so on……..? I have seen different - very different - placement option over the years! When I - a long time ago - had mine, one set (BL5000’s) were connected to the tv in the living room, they were mounted so that the tweeter was in ear height…..in that case they would have looked misplaced with the tv on a lowboard, if placed higher up. The other set (BL3000’s) were in the dining room and were mounted a great deal higher. The thing about these speakers is that they look kind of odd, if mounted too low….unless they are tv speakers. IMO they look best, if you place them as a picture on the wall. After all they are not speakers intended for critical listening, so don’t worry too much about ‘tweeters must be in ear height’. I’d say - there are no rules. As a wise man use to say…..it depends. By the way….welcome to the forum. MM

Hi, thanks for the welcome, and no they are not going to be used with a tv. we have the 5500 system currently running in the 'music' dining room, and currently using my partners rather nice Ruark bookshelf speakers. But for cleanliness of lines and clutter freeness i intend to put up the beovox's soon. I agree if they were mounted in ear level they would look odd (though when i tested them on the floor firing up they sounded incredible!). so your advice about treating them as pictures/ works of art seems to be along the lines i was thinking too. So i kind of have the height bit in hand but how about how far apart / in from the side walls would you recommend? I have 3.10m to play with. The right hand speaker will have a part wall to deal with, about 3 feet into the room then it opens out to the kitchen entrance. The left hand speaker will basically be next to a doorway, so also mounting it too low might result in leaving chunks of my forehead on the pressed steel edges! lol. Also one last thing, they seem to be orientable ie that one side under the steel houses the crossovers (i think) and the other side the speakers, which side would the steel housing be best placed? I am thinking along the lines of perhaps making the speakers on the outer edge thus giving the most stereo spread available. I have attached a wide angle pic to try help explain it.... thanks for your help, i have other questions and problems with my cd player and queries about the amp running hot but ill have to leave those 'essays' for another day haha. best regards jon

I think this bit i can reply to all of you? Tanks so far, please see text and picture copied from conversation with Millemissen. ========================================== Hi, thanks for the welcome, and no they are not going to be used with a tv. we have the 5500 system currently running in the ‘music’ dining room, and currently using my partners rather nice Ruark bookshelf speakers.

Jon, If it may help, I placed my 4000s in order to have their bottom at aproximatively 2/3 of the room's height. There is a couch in front of them, so they are a bit high but it's an annex system and the result is not so bad. I guess they would be OK in front of a dining-room table.

WOW that looks really cool! Yes thats more help, gives me an idea about height and width distancing. On the whole our dining/ music rooms less for critical listening, so i think i'll dispense with having tweeters at ear height etc. I have to consider what the main systems sitting on, please see my pic of the dining room wall to be used. thanks for your help jon

I suppose that you - at some point - will remove the boxes from there… I suggest that you make a piece of cardboard/paper in exact the same dimentions as the speaker/s and try to place that on the wall, in order to have a more visual impression of how it may look. P.S. I’d move the cupboard to the left to have it in the middle of the wall. Then the distances on either side could be approximately equal. MM

LOL, yes it is a mess but we have just moved in so things are topsy turvy. eventually i'll get those boxes of cd's cleared on the right and yes the top level of the record rack will be cleared off. For now its unlikely the rack will be moved centrally as it can interfere with the doorways 'flow'. We also have a proper hifi rack for the system to go in hard against the wall at the right hand side. For now we are just happy to have a (mostly) working B&O system to listen to. Your idea of making cardboard squares of similar size of the Beovox 3000's to stick up to work things out, distances and 'look', is a really good idea! thanks! ill deffo try that out. regards jon
