Hi all.
Had a great thread here (well, great for me who is learning)...
https://homerecording.com/bbs/showthread.php?p=3349584&posted=1
.. about where I should place my monitors to get "proper" sound. This has lead more to a "treat your room" thread so I though I'd start another.
Trying to avoid the more common questions, I'll start by saying,
- I've implemented the 38% rule, so my head is 38% in from the "front" wall.
- I have my monitors set up in an equilateral triangle, spaced out from the wall.
And I understand that, my largest problem will be getting anywhere near a flat response from the listening position, with the biggest problem of all being the bass frequencies, requiring bass traps.
Also, I've been reading Ethan Winer articles (who seems to be everywhere when you do a search for bass traps, probably due to the R rated video!) and have generally read on the internet about this topic.
Understanding that everything is a compromise in my perfectly rectangular room and no amount of treating (with my budget) will get me a totally flat response, at this stage I'm ready to commit to everything necessary to get a better response from the listening position.
Please see my crappy diagrams below which will probably save me a lot of typing.
I have a few variables to weigh up and I don't know quite how to attack this problem. I am up to the part where I take into account :-
- what shape
- where
- and with what material to use
The *where* part is fairly self explanatory at this stage; corners of the room and reflection points, as suggested by John H. Brandt in this forum - thank you.
The material? 100mm (4 inch) 48kg/cm2 acoustic insulation, placed in the corners and bridging where the roof meets the wall. Also, three panels for the reflection points at the two sides and the roof. Where the panels sit flat against the wall, i could set them 100mm out fro the wall to get a better result.
Shape? Yeah, good question.
** So, in the hope of getting some answers here, I'll be specific: **
How big do the reflective wall (and roof) panels need to be? I can calculate the theoretical point of where on the wall the speakers sounds will reflect, but how much area of absorption should I attach this ?
Does the covering material (open 'burlap' type material to let air and sound through) go on all of these proposed panels shown in my crappy diagram? Or do I need different material on the bass traps to the "first reflections" absorbers?
Ethan Weiner talks about alternating two different types of bass absorbing material here (http://www.ethanwiner.com/acoustics.html). Should I worry about this at this stage?
** big question **
Should I use the Room EQ Wizard (http://www.hometheatershack.com/roomeq/) to try and steer my construction, or is this just a crap shoot and a waste of my time in my predicament?
I guess I start with this and see what comes back to me.
Cheers,
FM
