[QUOTE="Bassick, post: 8207736, member: 656783"] Does anybody have any experience in isobaric loading. I'm currently pondering my next trunk setup. I have 2 15" subs that will take 4 cubes each. I have the space for a 8 cubed enclosure, but it doesn't leave much room for amp, crossover install. Sure I can still install the 3 amps I'm using and the crossover, but it just wouldn't be attractive at all. So, I'm thinking instead of a dual sub configuration (8^3feet), I'll opt for just 1 sub configuration (4^3feet). Which leaves me with 1 subwoofer unused. But, and there is always a BUT, I paid for two subs and I would like to use both of them. So, now I'm thinking ISOBARIC. With isobaric loading, I get to use a 2^3feet box instead of a 4^3feet box. My question is this, can I make a 4^3 box and isobaric load tow subwoofers, that are rated for 4^3feet each. Ok, here is my reasoning. Research (internet searches) tell me that manufacturers sometimes gives a recommended enclosure size thats sometimes half of what the sub can really handle. So, if one of my subs is recommended at 4 cubes, I'm thinking it will perform with a lower extension if placed in 8 cubes. Now, if I take the 8 cube thinking and apply isobaric loading, I get 4 cubes. So can anyone give me insight on using isobaric loading in double the size enclosure? [/QUOTE]
