The Soundsplinter doesn't model well in 1 cu.ft. from what I can remember, plus it's out of stock. CSS has a new 8 inch sub, the TRIO8, it has a lower Fs then the Dayton, has a Xmax of 14mm, and is $95 shipped. I'm at work and can't model it at the moment. Try modeling it and see how it does.

I did some modeling of the subs. The problem with the 240watt plate amp is it has a rumble filter at 18 hz and both subs will bottom out below 22 hz. If you were to use the Bash 300 amp, the rumble filter can be changed to 25 hz and both subs would be protected. The Dayton is a 4 ohm sub and the CSS is a 8 ohm sub. The Dayton will take 80 watts to reach Xmax. The TRIO 8 will take 150 watts to reach Xmax and has much more output.

I'm getting different port lengths then you are. A 3 inch port would be 22 inches long and two 2 inch ports would be 20 inches long. Both WinISD and the P.S.P. port length calculator say the same thing.

Also, changing the high pass filter to 25 hz involves changing 2 resistors on the amp board.(R26 and R25) If you're not comfortable doing this you'll have to find someone who is.

If you did go with a 10, what would the internal volume of the box be?

Go with the 8. Being corner loaded it should do fine for what your needs are.
