Skater229 Posted March 10, 2013 Report Share Posted March 10, 2013 I just built the box that Joe X gave me the specs for (12's up port back)... My question is "how far should the box be from the rear door on my blazer" 2010 Chevy HHR Panel (Work in progress) Pioneer AVHX-5800BHS McLaren MLM880's and MLT2's 2ea per door on a DC 175.4 Two DC Audio M4 Level 5 15's On A DC5K Alt CES 200/270+ 4ea Banks of Maxwell 2.7v 3000f caps for a total of 2000f 1ea XS 3100 and 2ea NSB FT170 Batts for 450+ah Not a HUGE build but here it is...

Krakin Posted March 10, 2013 Report Share Posted March 10, 2013 Normally Joe posts how far to keep it away from something at the bottom of his posts. Krakin's Home Dipole Project http://www.stevemeadedesigns.com/board/topic/186153-krakins-dipole-project-new-reciever-in-rockford-science/#entry2772370 Krakin, are you some sort of mad scientist? I would have replied earlier, but I was measuring the output of my amp with a yardstick . . . What you hear is not the air pressure variation in itself but what has drawn your attention in the two streams of superimposed air pressure variations at your eardrums An acoustic event has dimensions of Time, Tone, Loudness and Space Everyone learns to render the 3-dimensional localization of sound based on the individual shape of their ears, thus no formula can achieve a definite effect for every listener.

Krakin Posted March 10, 2013 Report Share Posted March 10, 2013 Then I would say as far away from anything as possible.

Skater229 Posted March 10, 2013 Author Report Share Posted March 10, 2013 Then I would say as far away from anything as possible. I wasn't trying to be smart with my comment... You are right Joe X did put the min distance to keep away, but I am asking if there is a distance that is the "sweet" spot to aim for... I know the test is tune is about the only way to find out, but also reaching out to other blazer installers if you have any info... 2010 Chevy HHR Panel (Work in progress) Pioneer AVHX-5800BHS McLaren MLM880's and MLT2's 2ea per door on a DC 175.4 Two DC Audio M4 Level 5 15's On A DC5K Alt CES 200/270+ 4ea Banks of Maxwell 2.7v 3000f caps for a total of 2000f 1ea XS 3100 and 2ea NSB FT170 Batts for 450+ah Not a HUGE build but here it is...

I don't think that there is really much of a difference after the minimum. If it is any closer it may interact with the way the air travels in and out of the port. Edit: Also is your back row folded down or do you just have a bunch of room to work with?

Skater229 Posted March 10, 2013 Author Report Share Posted March 10, 2013 no worries... But didn't know if there would be a distance that would let it load up more... 2010 Chevy HHR Panel (Work in progress) Pioneer AVHX-5800BHS McLaren MLM880's and MLT2's 2ea per door on a DC 175.4 Two DC Audio M4 Level 5 15's On A DC5K Alt CES 200/270+ 4ea Banks of Maxwell 2.7v 3000f caps for a total of 2000f 1ea XS 3100 and 2ea NSB FT170 Batts for 450+ah Not a HUGE build but here it is...
