Re: room orientation

Post by AVare »

Welcome to JLS RSD!

The reason for recommending shooting down the long axis is that with the size of rooms discussed here, the low end would vary more widely with amy given amount of movement, and to maintain rear reflections as long (time) as possible, teh longer dimension is better. As rooms are designed larger, these constraints become insignificant.

Those rooms are probably larger than what you have available.

The idea to have the room wider rather than longer is an "audiophile" concept that sort of makes sense in an unsophisticated way. When the room is wide, reflections from the farther side walls are softer and later. So that orientation improves imaging at the expense of bass response. But side-wall reflections are mainly a mid/high frequency issue, so they're very easy to treat. Versus bass problems that require much larger and thicker absorbers, and many more of them.

You can see graphs that compare the LF response directly for both orientations in Figure 3 of this article:

With that 13' dimension, it is too small for me to recommend usiing that as the length for the speaker setup. Look at some form of shell ala Waterland to give symmetrical high frequency symmetrical early reflection acoustics around the monitors.

studious wrote:in saying the room would be too short [small?], are you taking into account the fact that there is really no actual solid back wall at 13'?
Yes, and overlooked that when writing my previous post. More detail, a picture perhaps? would help immensely.
could you explain a little more about the need for a shell, and its benefits?
The shell is more like the front wall of a control room. It provides the symmetry for the monitor environment. I tried to find a picture on the web but had no luck.

Can you post a photo? A back wall that's partially missing means the room is actually longer for part of it. Regardless, the only way to know what you really have is to measure the LF response at high resolution using appropriate software.

The original poster is gone, Ethan: He scuttled off in a pathetic kiddie huff (after first deleting all of his own posts on the entire forum) when nobody wanted to join his Genelec fan club on another thread.

Go figure! :shock:

nobody scuttled anywhere. you're acting like an ass, though, by the way. is your main problem obsessive / compulsive disorder or erectile dysfunction, or both?

this thread had no response for days, i had already thanked the nice people that were helpful, and it is not a good idea to leave photographs like that posted for no reason.

anyhow, you really should mind your own business, if any.

what are you doing, trolling the forum like a lunatic, for opportunities to bad-mouth me?

if you are an example of a "senior member", then it must be a very lame forum.

Heheh. Like I said: pathetic, petty, childish. Wasn't it you talking about unprofessional responses in the other thread?

Except maybe for the reason that you accepted the forum rules when you signed up here. Did you forget about that? Maybe you should read the rules again...

Sorry, but I don't bother replying to web kiddies: I treat them with the contempt they deserve. :)
