Another soundstage question


There are a couple of soundstage related threads running on the amp/preamp section and they reminded me of a question I’ve been meaning to ask without hijacking those threads. The speakers are Vandersteen 2Ci and the system along with their placement is giving me a real deep and relatively wide soundstage - but not much further to the sides, but I’d like the height of the soundstage be little higher. The speakers are on the sides of a bay window, about 10’ apart and with heavy drapes pulled on either side and about 2.5’ behind the speakers. Much lighter curtains cover the bay windows for privacy. In my seating position that is about 10’ away from each speaker the top of the soundstage is just about the top of the speakers, sort of like I’m sitting at the same level as the musicians. The depth is realistic but I think the height needs to higher to give a better feel for the height of the singer standing in the middle and the rest of the band scattered at different levels within the stage. So having said all this, is the soundstage height mostly a function of the electronics driving the speakers or its the size/shape of the speakers, e.g., speaker height, tilt, etc., the listening placement, or a combination of all of the above. Thanks.

Kalali, I just re-read your OP. If there is anything that really sticks out re speaker set up that I think might influence the height issue for you, is the distance your speakers are from the wall/bay behind them. I really don't know your rooms dimensions but if possible I'd start with the speakers about 5ft from the wall behind them and adjusting your listening position accordingly, maintaining the equilateral triangle, toe in according to ear, and see what happens. To get the feeling of height (if this information is on the disc, which more than often it is not) is IMO the  holy grail  of audio. I used a test LP/CD called 'Depth of Image' by Opus3 which is just outstanding for obtaining the best soundstage possible. I spent years chasing this effect (and lots of money foolishly)!
To increase vertical soundstage, rake angle of the speakers should be addressed. Tilting the speakers can create a higher and more realistic soundstage.
@kalali - Did you follow the advice/instructions provided in the user manual for the speakers? Richard provides a recommended tilt based on your listener distance from the speaker.
The depth of a sound stage in any of the three axis is best treated in the same dimension. If you want width, improve room acoustics to the sides. If you want depth, improve room acoustics behind the speakers. If you want height, treat the ceiling and floor.

That is in general, but also, adding absorption on the floor around the speakers is often worthwhile. Regular pillows and blankets are a great way to experiment for free.

Also, treatments around the listening location should not be underestimated either. Too much focus is on primary reflections these days, and not enough to overall absorption and tonal balance.
