[QUOTE="dragonrage, post: 7238203, member: 574321"] Comparing 1 12 to 4 8s is not quite fair. CHEMMINS, it doesn't matter what the power handling of the sub is, as long as it's equal to or greater than the power it will be receiving. Otherwise, sensitivity and Vd (Vd is comprised of Sd (cone area) and Xmax (linear excursion), for those who don't know). Trying to find a subwoofer rated for exactly/close to the power you will be giving it is not necessary. SA-8 sensitivity: 78dB N3 sensitivity: 91dB 2xSA-8 = 78dB+3dB = 81dB 2x2xSA-8 = 84dB+3dB = 84dB Actually, one N3 WILL beat 4xSA-8. By a LOT. You'll need about 16 SA-8s to equal a single N3 watt-for-watt. For maximum output (assuming we hit Xmax before we hit power limits), compare Vd; I don't have the specs for that offhand, but it's just Sd * Xmax. [/QUOTE]
