RIGTH SIDE WALL Note that L shaped panel vertically placed in front of the Bookshelf side wall (on top of 3 drawers set). The idea is to try and minimize sound bouncing back off the Bookshelf side wall but I am not sure if I'm doing more arm than good right now :) The side foam panels on the wall are placed where I could see monitor reflection from sitting position (using mirror on wall). I could only see reflection where the two panels are placed on top of each other, but I put the other panel (rotated) as well because with such a small room I assume it is better to absorb from most walls

BACK RIGHT CORNER This corner sounds more Boomy that the others (playing Ethan Pink NOise from yamaha small but decent computer speakers with subwoofer placed under the front desk... I will re-test as soon as I get the proper SUB and I can fire up my A7s with the Sub 8) It could be that the door is creating additional boom

BACK WALL BEHIND MONITORING POSITION I didn't have panels left to place in front of the TV but I can use something (next picture)

I can place a big pillow in front of the TV or (as in the photo) a baby coat mattress. Ugly but it may help

LEFT SIDE WALL (DOUBLE GLAZED WINDOW BEHIND CURTAINS) I placed foam panels over curtains. Just used clothes little nails and bent them on the other side of the curtains. Question Shall I leave the foam on these curtains OR get rid of the panels and the curtain (double curtains attached together) will some how help.. and not having panels will make this Left Wall not mirror the right wall (with panels) possibly helping against summing/cancelling frequencies?

BACK OF A7s I had a chunk of Foam left and I was worried about the flat shelf-desk surface at the back of the A7. Good idea or reallyk bad idea to place this piece of foam bent as in photo? Cut it to only cover the base shelf area? Get rid of it all together?

UNDERNEATH MONITORS!!!\ I didn't want to place the monitors on the shelf because this would place them really close to the back Front Wall. I placed them on this white packaging staff. The white stuff is sitting on top of the Keyboard body... then I'm using MoPads under the monitors. Is this white stuff going to cause problems? I am hoping that it will only help to isolate the monitors from the keyboard and desk even more. Or should I try to get a couple of solid 20 cm speakers stands like the Acatama SL 200? Problem with using stands would be that I would need to place them to the left and right side of the keyboard increasing the distance between spakerrs therefore pushing my sweet spot (triangle) further back and closer to back wall

In case anyone was wondering or going to ask, these panels should be ok to remove/move around (rented house). I have used small nails to attach panels to walls. These nails shouldn't leave much of a sign and if holes are too visible I can easily fill them or use a quick coat of paint. I didn't use any glue or stuff like that. For the bass traps I have used some Velcro Strap as well to help the small nails. Actually the two back-wall bass traps and the bottom ones on the front wall are not attached to the wall at all, they are touching the walls but simply standing over other stuff. Panels on ceiling I have used Velcro Straps but I am not sure they will still be there tomorrow morning... If the drop down I'll do what I had to do with the Front top Right Bass Trap; simply add some strong glue (e.g. loctite) on the sticky side of the velcro strap (glue side) then attach to foam. The stronger Loctitie glue did the trick, the glue at the back of the Velcro Strap was not sticking well enough to the Foam. I suspect I will have to add Loctite glue to the straps for the panels on the ceiling Anyway guys, suggestions, answers to question included with photos all welcome. Using all these panels did get rid of reverb/resonance that was initially present (clapping hands). I also had to get rid of the glass-doors that where in front of the larger cabinets (back corners), the glass was vibrating and emitting a glass/metal sound so they had to go :) Thank you for your time and help guys (Update): yep, two of the panels from the ceiling went down :). Velcro not enough... so I added some glue and I HAD to use some small nail as well. There are a few nails per panel so hopefully it will last longer (more than 2 hours :)) this time around.

I see a lot of photos but was there a question in there? Please make it easy for me with small, bite size questions. one or two at a time. :) --Ethan

Hi :) Yes too many photos :). I added the photos to invite comments like... "that looks wrong, you should place stuff in a different way" or similar... I do have questions for which I would appreciate your opinion 1) I currently have my A7 monitors standing on top Isolator Foam which cannot be a bad think, but it all sits on top of white packaging material I got from the box the master-keyboard came in. I am assuming that this white stuff would help isolating the monitors from the keyboard body. Am I wrong? Is this white stuff (like Polystyrene) going to make things worse? Should I get a set of Atacam SL 200 speaker stands instead? 2) In the last picture above you can see the back of the A7s. Behind the A7 there is the surface of a desk-shelf. I placed a piece of Acoustic Foam over the shelf thinking that it would be a good thing to do. But as you can see from the picture the foam curves up towards the Bass Trap. Is this curved up shape a problem? Should I cut it so it rests flat over the shelf area behidn the A7? Should I simply remove it and leave the shelf top face naked? 3) Will the mattress (or pillow) some how help with the reflection from the TV screen located behind listening position? 4) Sadly my room is square and my listening position is in the middle of it which is supposed to be a really bad thing. Do you think that these wedged pieces of foam will help to diffuse waves a little bit so minimize cancellation/boosts or do these wedges simply absorb and nothing else? I have seen you really cool looking Real Traps and they are flat, so I thought that maybe the wedges could help braking things up a bit. I would have loved to get Real Traps but with the current UK £ value I decided not to. But I do think your Real stuff is better. 5) Being in a small room, is there anything else I could try to do to improve the situation? Well I will have to get one of those room analysis software packages and see I guess. I am getting an ERGO but I don't think it shows graphs for custom use If you can help in any way with answers/suggestions it would be great, but I do feel like I am in a situation where I simply need to analyze, fix, test again etc... Probably the MIC that comes with the ERGO can be used with some analysis software. Thanks

All the standard things apply - as much corner bass trapping as possible, plus absorption at the side-wall and ceiling reflections points. What your speakers sit on matters much less. But...

Exactly. Once you have a way to measure the room, then you can see exactly what happens as you move things around, isolate the speakers, and so forth. --Ethan

hi, i have the same problem with my room being a square. the biggest problem with that is that on some frequency (for me 47, 94, 141 Hz) we have huge problems. For me it ment 40 dB off difference between 47 and 56 Hz. It sounded soooo bad. After lots off reading i came to conclusion that normal products wont work for me and that i need to build really big basstraps, and i did build two for now, and that difference between 47 and 56 is now still 20 dB. Still long way till happiness :) ...so my point is, i am afraid that your current auralex(?) basstraps and tiles wont have much effect on controlling the low end. You will most probably have to build some yourself. I am not expert on this but i would just like to give you some off my experience dealing with my own room. Best regards and good luck, Tomislav

Thank you Tomislav Yes I am expecting issues. The auralex stuff I have, the bass trap won't have any effect under 75Hz (from what I know) therefore Im waiting to get the ERGO and see what happens then. Hopefully the ERGO will help and save me the time and money to try and fix all the problems that I may have under 500Hz. I'll try to use the Microphone that comes with the ERGO with one of those software-tools to analse the room (hopefully I won't need to buy another microphone). Sadly the ERGO which will also be my audio card to connect to the monitors hasn't arrived yet and it may take another week. Man I hate waiting even if I have tons of other things to do :) Thanks
