[QUOTE="Papermaker85, post: 8492378, member: 572595"] the driver has alot of do with the way it responds. generally they are similar to a vent box as in the need subs with more mechanical control over their mass to sound correct. typically you tune one chaber low and the other a octave above and half the size just as a starting basis.. im pretty god with box design. as long as the manufactures specs are accurate i can get you a good design. typically you start with about 80% of your typical ported box for the low tuned chamber. sometimes you can go much larger though if the driver has a very stiff suspension. The front chanmber is generally somewhere around 1/2 the size about around 2x the tuning frequency.. they can have substantual output gains over both ported and 4th order alignments when you build it to do so.. or you can build it to be about as loud as a ported box but flatter.. heres one graph that shows its nearly aas loud as a peaky vent box alignment but you can see it has a wider bandwidth.. you have winisd? ill help you try to understand it if ya want.. i will warn you though. its tricky to implement into the cabin because you never know how the cabin will respond to it, you just have to kinda tweek it.. you might have to drop your tune 3 hz and raise one 2 hz but they usually work fairly well.. dont be intimidate though. that's how you learn. hell thats how i learn. started off with a idea and worked at it till i succeeded.. btw i just got windown 10 once i get a screenshot uploaded ill show you the graph..
