[QUOTE="helotaxi, post: 1953313, member: 550915"] Most of the tonality of the subbass comes from the drivers playing the harmonics of the subbass freqs. As long as the midbasses are up to the task of providing the impact of the transients, all the sub has todo is provide the fundamental. When you need accurate output in the 20hz range, only a sealed enclosure is going to get you there. Try to tune a ported enclosure low enough to play those freqs and the phasing and group delay would totally ruin any chance of accuracy. As Loyd mentioned, minimizing excursion is important as well to keep the sub operating in its most linear range. But I will say again, one of the best ways to get a sub to sound good is to limit the range that it needs to play by crossing it over as low as possible. and pairing it with a midbass that will cover the rest.
