Acoustic wall panel

I have a bare wall in the living room that I want to provide with acoustic panels for decoration and of course to slightly improve the acoustics in the room. Much like the next picture would be great to make a home construction project there. I ordered at the Bax-shop four dark red 2 "wedge panels (Auralex studio foam 61x61x5 cm a € 18) that I want to glue in a window. I gamble the dark red color, usually the foam panels are grey but on a slate-gray wall it is tricky and I do have more dark-red furniture in the living room. I also ordered two small gray wedge panels (cm 30,5x30,5x5 a € 6) I for placing in small frame on the wall at the other side of the room.

There is something to do creative
with this wave shape foam 61x61 cm.

Surround speakers

Because the current satellite surround speakers (rear) are not comply with KEF R300 front speakers, I want to replace it with the following (Marketplace €70):

The compact Model 70S was designed as a rear effects speaker in surround sound applications, but could also be used as a main speaker in a dedicated sub-sat system, in particular with the matching 40B subwoofer. Using the same Uni-Q array as in the Model 90 centre speaker, uniform coverage over the listening area was assured, as was the timbre match with Reference Series main speakers.

Old hobby iMac with Windows 7 and 8.1

The old white iMac 20" (MA589LL - Late 2006  - Intel Core2Duo 2,16Ghz) on the hobby room I once again revived because the screen was broken down. I removed the screen allowing an external monitor primely can be connected to the mini-DVI port. I bought on Marketplace a 20 " Samsung SyncMaster 206BW (EUR 25), this gives a wonderful view of 16:10, 1920x1200px sharp.
Running in Parallels 9, I have a Windows 7 (32bits, X86) and a Windows 8 (64bit) version. The fully activated versions downloaded as ISO's and installed without further settings. This works great, in the Windows 7 virtual environment runs among other apps SolidWorks 2013.
