Room shape and acoustics.

[Automission]

So, my HT room has sloped ceilings. At the moment, my Tv/Speakers are inside an alcove where the ceiling slopes down. Now, I was wondering how will this affect acoustics and sound quality once I upgrade my speakers?
I was considering leaving it how it is, with the Sub and front/centre speakers all inside the front of this alcove. This is the basic shape, both on this side and the side opposite where I sit.

The Layout

(please excuse the mess, this isn't a dedicated Ht room)

Now the other sides are flat walled, however one is somewhat boxed in, leaving no space. The only other flat surfaced wall is where my window is. So, should I bother moving the position of my setup, or will these ceilings cause no obvious problems to my sound reproduction?

If you want more pictures of the room layout, please just say.

The link in my signature shows multiple pictures of my room (sloped ceiling, alcoves etc) you may have to go quite a few pages into it to see all the pictures though.


Anyways, what I am doing (since it's not done yet) is putting acoustic panels on the first points of reflection, and I'll also be putting bass traps in the corners (there are a lot of corners too)

Since your room isn't a dedicated theater space, this may be an issue, because asthetics can't be sacraficed that much, so make sure you have a LOT of materials in the room that will absorb sound..... such as...

Rug, LOTS of pillows, plants (these do work....) and maybe put a foam backing on pictures so you can absorb soundwaves without being too intrusive in the room.. Just put SOMETHING that will absorb sound in each corner (such as a plant) I'd keep the screen on the wall that works best for the room layout, and work on the acoustics accordingly.

beta man is correct, bass traps are important as is absorption.

can you post a plan of the room, it might pay to change the layout if you can, the alcove is likely to be boomy, though sloping ceilings help to avoid standing wave issues...

...you don't want sound reproduction, get some absorber.
Michael store is your best bet if you want to do it cheap. They have these yellow foam sheet 1.5 inches. You could spray paint it flat black if you like, but they work wonder. but if you have like couple hundred to blow, then yeah, get some Corwin material.

i freakin hate it when i see a messy room! ...

Okay, here is a sort of panoramic collect of images, detailing my room layout. Like I said, excuse the real mess, I need to sort it out soon. It's not a dedicated room, since I still live at home.
It's an all into one room. Just point out any really obvious, glaring faults I may have.

So, no nitpicking on wires everywhere, clutter and what have you. Just where I'l need absorbers, bass traps, etc.

It's a pretty small space, so I'd say you have enough stuff (like couch, bed etc) stuffed into the room to handle any sound wave issues..... I'd say you're working with the space you have....... not much more you can do with it..... The ceiling is sloped, but there aren't really any 90 Degree angles, so that's good.... I think I'd leave it "as is"

... i'm study to be an interior designer and wow if i ever see you in real life...i will kill you. No no i mean it, i will hire a fat guy to sit on you until you are dead.

lol on to serious matter. You will def need an absorber in the ceilling, look at the bat barn thread, here it is https://forum.blu-ray.com/showthread.php?t=72745

Is there any particular reason why you feel you need acoustical treatments. I don't think in your situation you will benefit from them. I would use that money on other upgrades or even better save it for a larger purchase like for new speakers, etc........

If your panels are not at least two inches thick you will see no real benefit at all. Not all panels/treatments are created equal either. There is real chance that it will be a big waste of time and money. Figuring out placement is something that you'll have to do on your end. We do have a thread here about this sort of thing with a fair amount of info, products and DIY.

If this project is important to you, do it right research and learn as much as you can. It takes a fair amount of knowledge to tackle a project like that. Simply throwing a few things up on the wall is likely to be a band-aid and have little effect if any. Also know, common flimsy foam treatments are a waste of money.

Sorry to sound like such a bummer........... Good luck !!!
