Best way to decrease the internal volume of a sealed speaker?

Best way to decrease the internal volume of a sealed speaker?

Liquid Nail a few bricks at the bottom, will make them feel heavy and expensive.

So using the Styrofoam...

Please correct me if my math is incorrect or if I am on the wrong track.

First my assumptions.
1 cu foot is equal to 1728 inches.
My present speaker cabinet is 0.75 cu feet or 1296 inches.
The woofers I am getting are said to perform best in a 0.45-0.65 sealed cabinet.

So, if I use 0.45 cu feet as the goal that would equate to about 778 total inches.
I have found available a 8x8x8 styrofoam cube and that would math out to about 512 in total inches.
So, if I subtract the 512 from my present 1296 it would leave the internal volume to be 784 inches or a little more than 0.45 cu feet internally.

Does this sound right???

Why not use the higher number as the goal? Actually you're almost there without doing anything. By the way, that should be cubic inches, not inches. 

geoffkait,

So, what is the negative of having a slightly larger internal volume than optimum size? Lack of bass definition? Low efficiency?

theaudiotweak,

Can you provide a source to obtain the Cascade V?  I see something called Cascade listed at Parts Express but it is a spray. Is that it?


BYW, The woofers I have ordered are the ScanSpeak Revelator 18w/8532G-007
