Well if any facebook friends of mine see's this they know i'm a 6th order Nuthugger. Anyways haha, one day I told my buddy, " let me build you a 6th order". He said sure. We bought some 11 ply pine which is seriously amazing if you have it in your area. He said he wanted more lows than the last box i designed him had. So i said sure. I ended up designing a 1:2 ratio series tuned 6th order. The rear was 2.6cu^3 net tuned to 28hz and the front was 5.2cu^3 net tuned to 56hz. Now this was a expiremental box. Iv been told the 1:2 will be peaky as all hell and have no range. But hey with a Planet Audio 1400.1 @ 2ohm load before rise were playing 17hz to 65hz beautifally. But i have noticed around 25-26hz and in the 45-50hz grey area, it gets violent loud.But its actually pretty nice, because its great for daily low end and metering. Enough of my talking heres some picture of the build, and ill post a link that shows the box on youtube playing.
