Madison Knight 10" in SpeakerBox says 366L right? [message #41908]

I am about to cut wood, and I am a little stuck with PiAlign.
I assume I have to use a pre-set speaker name, and the associated file in order to run PiAlign. Is this right. I've taken the T/S from Madison's site for the Knight 10", and this is what I get:
Qts=.578
Qes=.599
BL=13.89
Re=10.4
Xmax =4mm
eff=95db/1w
200w
I'm not sure if this is all, but the reflex box comes out at 366L, 36hz
So, I'm xover at 90 hz to subs, so I think I am going to take the 260L aperiodic options.
'does any of this sound correct.
Thanks for your help to a newbie.
Sincerely,
-3db
too big

366 liters for a 10" driver? oooo.... thats really big

As you go through pi aling enter the following fields

description= anything you want to call it
Type= M
lo cut= 50 (if you have 70hz sub 50 would be good)
hi cut= press enter for no entry
Eff= spl 1w/1m
power= watts max
impedance= Re (4,8,16 might get you close)
quantity= number of drivers per enclosure

for pi align you need to know from the t&s parameters
Vas this will be the VAD input (must convert to Cubic Feet)
Qts 1 devided by the Qts will be the QD input 1/.578=1.7301
Fs this will be the FD input

Enclosure type= B ( for bass reflex)
Port= C / cylinder R / rectangle

you now have all the dimensions and volume in cubic feet acording to pi align.
