Box Size Requirements

[Karz_2000]

Guys, what would happen if I build a box that is significantly larger than the required volume, say, by 50% or more, assuming that the sub manual only gives a minimum volume?

the bass wouldnt be as tight and the power handling of the sub would decrease

not to mention losing output.

Stick to the recommended enclosure size. The manufacturer know what size box that sub will work best in.

to a certain point, a larger box will allow the sub to reach lower frequencies, at the expense of sheer volume. it will also require less power to get the sub to that maximum volume. sometimes there can be a difference in tightness, but as long as you don't overdo it (stay under twice the rec'd minimum), i'd say give it a shot, see how you like it, you can always build a box to spec

btw, the comment about the 'powerhandling' of the sub is slightly misleading... it's all about xmax...

and mac's right, the manufacturer tends to know what's best for their sub, but your situation could be unusual...
