Smaller box = ???

What kind of difference will I see with a smaller sealed box? Right now I have my sub in a 1.5 cuft sealed box, but I was told that for this sub the optimal box size is 1.0 cuft. Any ideas on how this will effect the sound? BTW it's a custom sub using a TC9 motor that TeamPSI made for me.//content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

 
A smaller sealed box will generally...

a. increase mechanical power handling

b. increase SPL (tends to make a peak in the response)

c. decrease efficiency

d. decrease SQ (tends to not play as flat)

e. increase roll-off (tends to not play as low)

I'd asterix b. and d. those would be comments aimed towards a very small enclosure.

Do you think it would make a difference in going from a 1.5 cuft box to a 1.0 cuft box? BTW, he recommended a 1.0 cuft box for this sub.//content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

 
I've used a 1cf. box for a sub very similar //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

Pretty good performance.I didn't really test it in a larger sealed box.But I honestly doubt you'd hear THAT much of a difference.Although, you might.Depends on how sensitive your ears are.

 
Eh it'll work...not optimal but not horrible either //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
Appearently you have no hands on experience with the sub at hand //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

Generalizations are a no no!

 
I got a 12 made by TeamPSI as well off a tc9 motor. I was going to put it in a 1.4 cube sealed enclosure.

Everything I see about the TC9 it self and subs that use the same motor they do fairly well in smaller sealed enclosures. Check out Tcsounds site and soundsplinters site.

I have the TS parameters for mine but it probably will not do you any good as they are customs...

 
Well, in this case maybe I'll build a wood box and see how the sound is before I build the fiberglass box so I only have to make one of the fiberglass ones. Thanks for all of the input guys!!

 
I think it is the same as the SS RL-p. If it is SS says 1.25 sealed. But if the guy that made it says 1 go for it. A bigger box will most likely help with the low end but will lower the power handling a little.

My advice still applies //content.invisioncic.com/y282845/emoticons/tongue.gif.6130eb82179565f6db8d26d6001dcd24.gif
