What is the technical reason why 2 subs are better than one?

oh yea? 2 15's is better than 3 12's [img]tongue.gif[/img]
To the original question, more cone area=louder. The amp doesn't make a huge difference, as long as you have clean power, you're still moving twice the air.....with more power you move even more air.....rule of thumb is, double your cone area, you increase SPL by 3-4 Db....or so I'm told...this is not always the case though.

Matching impedance with 3 woofers would be more difficult than with two. Unless you were running, for instance, a JLAudio amp where impedance doesn't matter. It will still produce the same power at 4/2/1 etc ohms.

Sub quantity depends on what you are trying to achieve. one is not better than the other
Lethal I know JL says there amps regulate power into all impedences but I think if you measured what the amp actually does you would be in for quite a shock.
To sum it up, my understanding is [img]graemlins/bs.gif[/img]

2 better than 1
Maybe a good formula with money....as in having 2 dollars is better than 1 dollar.
With 2 subs you get twice as much cone area as one sub....dont know if that is better...I suppose for the majority of people it is.

1 12" would have approx 60sq" and 1 15" would have approx. 110sq".
Therefor, 3 12's = 180sq"
2 15's = 220sq"

Lessy,
A 12 inch woofer has approx 108 square inches of cone area.
A 15 inch woofer has approx 168 square inches of cone area.
Therefore (3) 12 inch woofers and (2) 15 inch woofers have almost the same cone area (324 vs 336)
