nice to hear from you again, sir barrister...
i guess my query is incomplete. perhaps, my question should go this way -- with the limitation on the the HT area, how can we mount his surrounds, specifically the right surrounds (aside from the traditional mounting spots), and still attain the soundstage we should attain?
First, accept that you will not be able to attain the correct soundstange with a room layout like that. All you can do is approximate the proper soundstage as closely as possible.
That's because wall location is important in producing the proper soundstage. The left surround properly interacts with left wall and rear wall, but you don't have that on the right surround. So the left and right surround sounds will never match no matter what you do.
... the nearest place where we can mount it is on the concrete beams of the ceiling. however, if we hang it from there in an identical height with the left surround, we fear that the brace might hang way down. not good, aesthetically. that's why we thought of hanging it in an angled position.
Yes, you can hang it from the ceiling and angle it towards the listening position. For an aesthetically pleasing look, left and right should look balanced. So if you have no choice but to hang the right from the concrete beams of the ceiling, then the left should also hang from the concrete beams of the ceiling. Otherwise, parang mukhang naka-ngiwi ang lalabas diyan ...
What I'm saying is that your decision should be based on the underlying rationale behind the placements.
The surrounds should be on the sides, slightly to the rear, and slightly above.
So if the only option is to hang them from the ceiling joists and angle them downwards, how should they be angled? Nakatutuok derecho sa listener? No. Dapat nakatutok: (a) slightly behind the listener na, (b) slightly above the listener pa. That way, you're as close to ideal as possible.
Will it produce the ideal sound stage? No. The absence of a right wall has already messed up the sound anyway, so additional variations won't matter too much anymore.
... Pwede na din... i still feel the effect pag may eroplanong dumaan sa side, sumabog sa likod, nagsalita sa likod... Pag nag papan ang sound around the place...
OK lang yon. It's all about compromises.
But still, dapat may starting point ka pa rin. Kaya dapat alamin muna kung bakit ganon ang recommended placements. Pag alam mo na ang rationale ng suggestions nila, may basis ka na para mag decide ng sarili mong placements, lalo na kung hindi talaga puwedeng sundin ang recommendations dahil sa room limitations.
