you really need more than 18"...maybe you could pull them out for listening sessions and put them back when done...I have had the 1b's and my dad has the 2cesigs...just my 2c
p.s. Bigtee is pretty much on with his measurements so no need to repeat him...follow his advice and you'll be happy...if you feel that there is not enough bass when pulled out, big deal...there are lots of inexpensive subs that are pretty decent and you still get the incredible sound stage benefit of having the peakers pulled out.
