I'd been hoping the answer would turn out to be a clear cut 'amplifier' but not to worry. Almost without exception:
1. It's better to implement a sub along with bass management as opposed to using speakers full-range;
2. It's better to use multiple subs as opposed to just one.
...and this got me thinking:
'why don't manufacturers specifically manufacture subs using high quality drivers yet combine them with amplifiers that aren't particularly powerful'?
I reasoned that if a sub was specifically marketed for incorporation within a multi-sub system, that with the excursion of each sub being (markedly?) less than that of just a single sub doing all the work, amplifier power could be (significantly?) reduced yet still remain sufficient. Reduced manufacturing costs would then ensue.
Lower manufacturing cost = lower cost to customer (in theory
![Roll Eyes :rolleyes: :rolleyes:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
) = more units sold (remember that a minimum of 2 would be bought and it's unlikely that the cost of each would be as low as half that of one) = good for both manufacturer and customer.
What say you?
