wuzzzer Posted September 17, 2006 Share Posted September 17, 2006 Tonight I rearranged my basement and also put up some foam/corner bass absorbers on the back wall. The first pic is the before picture. (Sorry about the mess!) Quote Link to comment Share on other sites More sharing options...

wuzzzer Posted September 17, 2006 Author Share Posted September 17, 2006 Yikes, I didn't realize how dark the pics were! Well, the foam consists of 3"x3"x24" corner foam blocks and 2"x12"x12" wedge foam tiles. Tomorrow I'll try and tackle the first reflections on the side walls and see how it goes from there. As you can see my basement ceiling and walls have pretty odd angles. Quote Link to comment Share on other sites More sharing options...
psg Posted September 17, 2006 Share Posted September 17, 2006 But... How does it sound? [] Quote Link to comment Share on other sites More sharing options...
wuzzzer Posted September 17, 2006 Author Share Posted September 17, 2006 Sounds excellent so far. The rear foam has helped the sound seem more immediate and direct, it no longer is echoed all over by the angles in the rear wall and ceiling. Its interesting to put your head up to the foam and them move it directly below it. There are very strong reflections coming back from the untreated part of the wall but the treated part sounds almost completely dead. The room has had a problem with boomy bass in various areas too and they seem to have been smoothed out nicely. Quote Link to comment Share on other sites More sharing options...
wuzzzer Posted September 17, 2006 Author Share Posted September 17, 2006 Foam setup is 95% complete. I honestly can't believe how much of a difference it made!! I agree with others who have done it, other than different speakers, this has made the most impact on sound quality compared to any upgraded amp, CD player, etc. My total investment was $63 shipped. It looks like I will only be using about half of the foam that I received, too. I'll either put the rest up on eBay or offer it for sale on here when my project is completed. The DIY bass traps that I made from the wedge tiles & corner blocks have increased the lower octave bass noticeably. My wife said things seem more muffled, but I think they seem much more flat and natural. Of course she has commandeered the basement and is currently watching the Food Network so I can't mess around with music or movies quite yet. [+o(] I'll have to toss Star Wars III in or maybe Behind Enemy Lines to test out the dynamics of the new setup. Quote Link to comment Share on other sites More sharing options...
wuzzzer Posted September 17, 2006 Author Share Posted September 17, 2006 I think I'm done. It was a pretty easy install with the spray adhesive. I used a total of 5 corner blocks and 23 tiles. Front of room pic: Quote Link to comment Share on other sites More sharing options...
damonrpayne Posted September 17, 2006 Share Posted September 17, 2006 Wuzzer do you have any before/after measurements of the room concerning the foam? Quote Link to comment Share on other sites More sharing options...
wuzzzer Posted September 17, 2006 Author Share Posted September 17, 2006 Wuzzer do you have any before/after measurements of the room concerning the foam? No, I don't. It would have been interesting to have them though! Quote Link to comment Share on other sites More sharing options...
sfogg Posted September 17, 2006 Share Posted September 17, 2006 Congratulations! Starting to deal with a room can give huge gains in performance. "I think I'm done. It was a pretty easy install with the spray adhesive." If you used the spray adhesive FoamByMail sells you aren't done..... ... the stuff holds OK on sides walls for awhile but eventually they are going to fall down again. Used on a ceiling the tiles will be falling within a day or two. I put up 1" foam on the entire ceiling in my room with that adhesive and by the second day at least half of it had fallen again. I tore the rest down and put 2" stuff up in its place with Liquid Nails. That has held it perfectly for about 2 years now. Shawn Quote Link to comment Share on other sites More sharing options...
rcarlton Posted September 18, 2006 Share Posted September 18, 2006 I second the recommendation for liquid nails. I used velcro the stick mine up...sticky side of velcro could not adhere to the foam for more than a day or two. Used Liquid Nails...nary a tile has fallen.

colterphoto1 Posted September 23, 2006 Share Posted September 23, 2006 Wuzzer do you have any before/after measurements of the room concerning the foam? what on earth would you measure? Quote Link to comment Share on other sites More sharing options...
mas Posted September 23, 2006 Share Posted September 23, 2006 Impulse responses for various listening positions, which when convolved into 3DWaterfall plots display room modes and ETCs for specular reflections show absolute and relative arrival times and intensity.
