Does Cubic Feet Really Matter With A System?
Does Cubic Feet Really Matter With A System? Im about to by a subwoofer & all the ones i want they say there is not cubic space for the subwoofer...does space really matter to a sub? or is that a bunch of bull? thanks!
I am not sure exactly what you are asking, but the box you use will definitely effect the frequency responce of the driver. What drivers are you looking at that you are unable to accomodate?

the amount of air inside your box GREATLY affects the output of the sub, loudness, clarity and tone are all changed when box volume increases/decreases
and whomever said you don't have enough space doesn't know how to build a box...

What type of sub is it and what type of box are you looking for?
Any particular reason for having to have a 15" sub. Done properly you could pull more out of a 13" sub or two 12' subs. It would also be alot more verstatile as far as balance between SQ and SPL I would think. What vehicle is this going into? And like everyone else has already mentioned airspace volume is very important in driver efficiency and sound. If you build your enclosure too small or use the wrong enclosure your throwing away the money you spent on your sub. Instead get the right sub for the amount of space you have and build the enclosure accordingly. It will sound better and more importantly it will fit.

No way you will get it in the trunk compartment......unless you do some custom building and get creative. According to that ebay site, the sub would like a vented box....which requires more space typically (the specs listed there recommend 5 cu ft - I know nothing about your sub besides the specs there). If you want subs in the trunk area only your best bet is build or buy a custom box for that area...you aren't really going to just throw a box down there (then again I have no idea what year Camaro you are talking about). If you go with the hatch area - there are 15" subs out there producing just as much power, and work well in sealed enclosures with usually only 1.5cu.ft-2.25cu.ft of volume...

Verdad Gallardo According to Memphis Audio web site: there are 2 MOJO subs listed both have the same airspace requirements for the M3MOJO15 and the M3MOJO15Q. The first number is the minimum required airspace volume and the other is the optional airspace volume direct from thier pdf. files.
sealed: 1 sub= 2.5/3.0 cu.ft. 2subs= 4.0/4.5 cu.ft.
vented: 1 sub= 3.5 cu.ft. tuning frequency of 40 slot port dimension of 15.5x2x16.5
To give you an idea of how much airspace is required the average stealth enclosure is .5-.6 cu.ft. So about 4-5 stealth enclosures is equal to the amount you'd need for 1 15" M3MOJO sealed. Guess it could be done but these subs are also recommended for SPL which may or may not be a good thing as far as SQ. Some SPL subs are really only good for a loud "burp" designed for SPL competition. Don't know if this is the case of the MOJO subs. I know the standard M3's are really nice but the M3MOJO I am not as familiar with. Good luck and hope it works out!!!

Just wanted to ask if you had any specs for the "hifonics 2000"?
I'm having a hard time finding specs on mine, but it's an old Zeus and it was a 2 channel.
Thanks.

I never did like doing this, I believe you should do it once and do it right.
Sometimes I am so limited on space that I have no choice.
I always try to steer them into getting a smaller sub in the right airspace.
yes air space is very important. It is actually the most important part of the design process

Unless you go with the free air subs , it does matter big time....
