One sub, especially a SVS, will probably do, but two will almost always sound better. Subs are all about displacement, double the drivers and your subs no longer have to work as hard to put out the same spl and that means less distortion. ie an ib  BTW if an ib is an option I will side with the other guys and say go for it. |
....and if you check some of the test where the frequency response is plotted at various SPLs, you'll find that many subwoofers loose their bottom end the louder they're played. The workaround for this is to use multiple subs so that when you reach those sound levels, you're still at the flat part of the subs operations.
