[QUOTE="Silas Pradetto, post: 84103, member: 34"] Re: More double 18's in progress. One driver in a box half the volume with half the port area should be identical to two drivers in the box (with double the volume and port area of the single driver box). I'd simulate it but there's no Bassbox on this shop computer. Also - recall that a single driver handles half the power and has double the impedance - you need to correct your input numbers as such - it looks like you're simply applying the same power to the single driver box - and it should be half that. Also version 2 - have you ever measured Fb of a completed sub? The calculation is usually quite far off from reality. [/QUOTE]
