size differences

[allConfused 0]

what differences would i notice with a 12 inch with these differnt box sizes, 1.0CF, 1.3CF, 1.5CF

would i loose any sound quality or puchiness as i went bigger? i ask becuase i found a way to make a bit more space in my truck and as you all saw my box design in another post it ended up around 1.25CF after displacement.

if you think it will make a "good" difference i can crank it up to about 1.3-1.4CF after displacement.

I had my box done today, and this issue was brought up. The designer insisted on having it 1.25 cubes, and I kept resisting. I specifically instructed him to have it 1.5 after displacement. So what can we expect from the differences(0.5 - 1.5 cubes)??

Larger box = lower F10's, higher F3's. More bottom bottom end. There won't be a huge difference in sound, but a larger sealed enclosure almost always gives you more bottom end. SQ will still be great in any box bigger than 0.4 cubes for a Magnum 12.

who wait Nick, .4 cubes???????? or .4 cubes over 1.5?

Nick ignore the last reply, I completely understand it. My box without brackets and driver is around 1.5. I guess after displacement it would fall somewhere around 1.2-1.3. I am happy that it complies with your parameters and recommendations. =)

In my enclosure building experiences, I have almost always gotten a lower F3 as well as F10 as box volume has increased. Now this is only in general, but I have found when I go too large, that is when my F10 lowers and the F3 rises. But that's just my experience.

well i got it up to 1.3CF after displacement without redesigning the whole box so thats as big as it gets hehe.

should be a bit of a step up from 1.25

wow i just multiplied 1.3CF by 20 and 30 percent( this is the increase most say you get with an effective polyfil job) and after displacement my box would be like 1.6-1.7CF

will polyfill really do that or am i smokin crack?

...........

[Electrodynamic 2]

Yes it will effectively increase the box size (make the speaker think it's in a bigger box that is).

[allConfused 0]

that just seems like a huge increase. should i tone my box down so it stays around 1.5CF with polyfil or is your recomended top box size or 1.5 on the site assuming it guna have polyfil in it?

[Electrodynamic 2]

No, just keep what you have and either use polyfil or don't use it. You can always take it out if you want (or vice-a-versa).
