99s10dowork Posted October 31, 2009 Report Share Posted October 31, 2009 I was wondering what the differences were if you were to go with a box as big as a company says to go, or as small as a company says to go? how will it affect a woofer? like if a company says ported-1.75-2.5...which would perform better? any input appreciated...anymore info or explaining what i mean better ill try...didnt know how to go about askng this!

OrionStang Posted October 31, 2009 Report Share Posted October 31, 2009 This^^^. You'll need a more powerful amp with the smaller box. Quote SMD Super Seller My Feedback Thread Link to comment Share on other sites More sharing options...
99s10dowork Posted October 31, 2009 Author Report Share Posted October 31, 2009 if you make the box bigger would the sub still be able to handle about the same amount of power or would you actually have to run less than in a smaller box?

raytard Posted October 31, 2009 Report Share Posted October 31, 2009 there is a minimum and a maximum in which the woofer works well. towards the minimum, output and low end extension (ability to hit low lows) is usually hindered. power handling is increased though. on the larger side, the box is more effecient (louder with the same power) and there is more potential for hitting the lows, at the sacrifice of some control and "crispness", but mechanical power handeling is also decreased. its all a tradeoff and you have to chose whats right for you. if you dont know split the difference. if its being overpowered go near the min. if you have alot of room/really know what your doing/want all out spl/cant ever power it properly go for max. otherwise you'll fall somewhere in the middle.

Decaf Posted October 31, 2009 Report Share Posted October 31, 2009 (edited) if u are referring to ur 12" bl in 1.8cuft with a bxi2000 then thats already pushing it whats ur port size btw? lows will sound better with a larger box and it should be less peaky as well Edited October 31, 2009 by Decaf Quote Link to comment Share on other sites More sharing options...

99s10dowork Posted October 31, 2009 Author Report Share Posted October 31, 2009 (edited) what do you mean pushing it? ok haha just caught that...thats what i was wondering. this box likes to hit certain notes and after that it drops of really quickly on both sides of that...thats kinda what i was trying to get at...if making the box a little larger would help make it better overall on response.

raytard Posted October 31, 2009 Report Share Posted October 31, 2009 yes, a larger box generally can have a flatter response. check out a program called WinISD, it lets you play with box size/port size/and your specific woofer to determine the like mathmatical response of your woofer in an open air environment. you can smooth peaks and see how the box performs before building it (it even recognizes a DB gain from a new design, so you can play around before cutting wood) just keep in mind that cabin gain comes into play, so the idealized open-air calculations can really go to hell in a vehicle.
