Aluminum isn't anything special. A wood box will be just as loud if not louder if built right.The aluminum is thick enough to not flex the way my guy designed the box on the inside let's the bass flow just fine no unwanted vibration or none of that it's really loud on the inside I had a wood box before this one and the wood box is no competition for the aluminum one
The material isn't what gets it loud bro, the box size to port dimensions is what gets it loud. What you had before was a sh*t design thats all there is.if you build the exact same box with same port specs and airspace all exact, the wood will be louder. Theres been a whole write up all about how metal enclosures are vastly inferior to wood and has been proven so.The aluminum is thick enough to not flex the way my guy designed the box on the inside let's the bass flow just fine no unwanted vibration or none of that it's really loud on the inside I had a wood box before this one and the wood box is no competition for the aluminum one
