Der skal jo ikke være hul i midten af lydbilledet.

Ved nærmere eftertanke tror jeg summen af vinklerne i en ligesidet trekant er 180. Og der kan ligge seks trekanter på en cirkel. Så det matcher surround

Her er hvad Richard Hardesty skriver i en af sine Bulletiner:

2. Place the speakers so that the included angle between them as viewed from the listening position is 60° or less.

A 60° included angle means that the distance between the centers of the speakers will be equal to the distance from each speaker to the listener. This is the maximum spread that I recommend. I prefer to position my speakers slightly closer together than this.

Spreading the speakers farther apart does not make the image bigger, it just makes it more diffuse. Time- and phase-correct speakers will produce an image that is not limited in width by the outside edges of the speakers. This image will extend out well beyond the outside edges of the speakers. Placing the speakers slightly closer together than the distance from each speaker to the listen er usually won’t diminish image width and usually will improve image focus.

Think of the speakers as a window through which the performance is viewed, not as the defining boundaries of the space where the performance is occurring and you’ll get a new mental perspective on the question of where to put the speakers.

Mere fra Richard Hardesty

6. Place the speakers in a symmetrical environment.

Complete symmetry in the environment around the speakers is a desirable goal that is often difficult to achieve. A symmetrical environment means that the walls beside and behind the left speaker should be duplicated by mirror image walls beside and behind the right speaker. I am fortunate to have that situation in my room but many living rooms simply won’t allow it.

In my experience, what’s behind and directly beside the speakers is more significant than what’s farther in front of the speakers, towards the listener. What’s behind the speaker is more important than what’s beside it, if you have to choose.

Gælder det også en subwoofer? Jeg har en subwoofer (Elac 2030) stående 30 cm fra en hjørne.

Jeg har gode erfaringer med at placere en subwoofer imidten under fladskærmen. Jeg bruger faktisk subwooferen som bord for fladskærmen..
Den kobler godt til rummet.
Richard Hardesty, som jeg nævnte før, bruger hjørneplacering.

Jeg tillader mig lige at hijacke tråden til et kort spørgsmål relateret til højttalerplacering; nærmere bestemt højttalere i hjørner.



Hvor suboptimal er ovenstående opstilling, f.eks. m.h.t. buldrene bas?

Den placering på tegningen er ikke så god. Højre og venstre side skal helst være ens.

Det kan godt være at mine tegnetalenter ikke er imponerende...

Idéen er at højttalerne skal være symmetriske omkring hjørnet - altså begge 30 cm fra væggen og med 100 cm mellem hinanden.

Spørgsmålet går på om hvad denne opstilling betyder for lydbilledet kontra når bagsiden af højttalerne står med ryggen direkte mod muren, så at sige!

En Dali højttaler er ikke designet til at vinkle ind imod lytteren, det samme gældende for Audio Vector
