i'm going to assumed that you know how to treat a room the right way.

saprano · 02-12-2008, 08:45 PM

care to give me some tips?

yellowblanket · 02-12-2008, 08:57 PM

don't overdo on the placement of the panels. Use a mirror and find the first reflection point of the speaker and place the panel there. (1 inches away from the wall would be good.)
I assumed that u know how to find reflection point of your speaker?

Use 2" panels, if you are not handy with the tools, i suggest buying the already made panels from the site, they are just as cheap and will save you a lot of trouble making the frame yourself.

saprano · 02-12-2008, 09:02 PM

how do i find the first refection point? and isn't it better if i get the bigger pannels.

mattym · 02-12-2008, 09:14 PM

sit at your viewing spot and get a friend to hold mirror on the side wall near you, then move toward the speakers, when you can see the speaker in the mirror, thats the spot.

i work for a company in europe that works with:

www.rpginc.com

top quality products in the US, bit more pricey but they really do know what they are talking about. Im not saying buy from them, thats up to you!

if you want a bit more help off site, email me your room dims and a plan and i will send back some ideas for you, my address is matt @ rpgeurope.com

Mods i hope this is ok,, im just offering help to a fellow member, im not pimping.

saprano · 02-12-2008, 10:00 PM

i dont see any email adress its just a website...........anyway my room is about(this is just a eyeball guess) 10 feet long and 10 feet wide from wall to wall and wall to door...... 8 feet wide from wall to the closet.

mattym · 02-13-2008, 07:17 AM

ok i will take a look at this for you..

My speakers are in my ceiling, is there a recommended method for me?

MouseRider · 02-13-2008, 08:29 AM

Basic acoustic treatments to prevent reflections can help pretty much most installations. If you want to go serious, there are also hardware you can use to suspend your drywall to prevent vibrations. There are plenty of easy to install materials these days as the links posted before will lead you to I'm sure.

But when it comes to bass-traps and other forms of more advanced acoustic treatments, they aren't just "drop it in and your room will have better sound" accessories.

If applied wrong, these things could actually make your room sound worse, especially bass or frequency traps. Many of the advanced acoustic treatments are meant to deal with problems with standing waves and frequency problems (i.e. null points, spikes) and you really need to have the right equipment and some acoustic knowledge to do things right.

Many new receivers today have automatic room equalization systems which can actually give you better results than just blindly or randomly sticking in acoustic treatments.

I would never recommend random placement, i always asses a room with as much information as possible, though it is possible to give a fairly accurate idea to people just from the dimensions. Modeling software is a powerful tool!

You cant beat a proper evaluation with measurement tests etc, trouble is, that costs money.

can you do a little drawing or plan? and i need the height...

Beta Man · 02-13-2008, 04:42 PM

SPL Meter would be your best bet.......

actually realtraps and other well known acoustic company's says you can just drop it anyware and expect better results, just dont have to many pannels. as long as something is doing the absorbing its better than nothing.

Exact placement is not critical, nor is maintaining perfect symmetry. Bass waves bounce all around a room, and eventually find their way into every corner

i have no idea how to that.............its about 10 to 12 feet high.

mattym · 02-13-2008, 07:11 PM

dedicated bass traps can go anywhere, but they are most effective at points of highest pressure, ie, in corners, which is what realtraps are talking about

I wouldnt put broadband absorbers just anywhere though, you want to try and balance the room for music and film to get the best from 5.1 etc. if you put panels all over one side of the room then you will get an unpleasant dead area to one side which would affect imaging and seperation.

rough and ready calculations based on teh assumption that your room is 18x10x8, you will probably be looking at modes clashing at around 270hz and possibly around 60hz, so i would look at putting some traps in at the corners, floor to ceiling, which products you choose is up to you.

If you go with FG panels then go for the thickest you can get, there are some specialist panels that can get down to 60hz, though these tend to be large and expensive. At the front i would have some thin absorption, just to keep reflections down from the front wall, i would then look at some sort of absorbing/diffusing combination tools for at least the front 3rd of the side walls, definately past the first reflection points.

For the rear personally i go for diffusors or absorbing diffusors, come along the side walls at the rear 1/3rd, i find this gives best effect for surround, i dont like dry rooms, but thats my personal taste.

I will email a much more detailed write up to the OP

saprano · 02-13-2008, 07:18 PM

i was going to go with the pannels from the link yellowblanket gave me. do you know how true are those absortion numbers? iv heard some companies giving out false numbers.

mattym · 02-13-2008, 07:39 PM

the figures quoted match(in fact slightly exceed)manufacturer data for the raw material, so its not bad. The panels will be soft though, and bass control with the 4" version isnt as good as it could be, so be wary of that, they have a wood back from the description, that limits the ability to improve performance. Very cheap though!

saprano · 02-13-2008, 08:23 PM

is soft not good why? and dont all acoustic pannals have a wood back. and are you saying i shouldint get these? do you know of anything better?
