[QUOTE="sundownz, post: 5933045, member: 549523"] I am going to start putting corner pieces in my box as well as adding resin. I will be tracking my gains from these things here. I will do each corner with a 45 degree piece first (ripped 4x4 lumber). I will also try pieces that are cut into an arc (same 4x4 but with an arc cut) to see which is louder. This will be done one corner at a time. This may take a while but I am going to start today. Base-Line score from the end of my dampener log : 155.2 dB @ 48 Hz --- First piece in place - screwed in with tape along the top as that edge was rough: [IMG]http://www.sundownaudio.com/misc/96_Jeep/v2_dual15_box/Modifications_Begin_5-13-09/CIMG2224.JPG[/IMG] This resulted in a GAIN : [IMG]http://www.sundownaudio.com/misc/96_Jeep/v2_dual15_box/Modifications_Begin_5-13-09/CIMG2225.JPG[/IMG] --- I tested 49 Hz as well to make sure my frequency did not change - I metered 155.2 dB @ 49 Hz. I also gained 0.1 dB here compared to before but it is still not as loud as 48 Hz. [/QUOTE]
