so i input all the specs for the Celestion G18Q-400 because i want to make a nice cabinet for electric bass...and everything seemed nice until i looked at the depth measurement. i used a 0.75" wood thickness offset too. anyway, it says 14 inches. that doesn't seem right at all for a cabinet with an 18" driver...what could i have done wrong? try it yourself, see if you get something better.the specs for the G18Q-400 are as follows:
