Should I convert the 15" to an 18"

The human ear can only determine differences in volume of 3 dB or greater.

Nope. The human ear can detect changes of 1db. 3db is a doubling of acoustical power (technically "twice" as loud). But to say that human's can not detect a change smaller than 3db is inaccurate.

Also need to realize that an 18" is going to use a much larger enclosure. You got room for it?



Yes, a few months ago they were out of 18" baskets. So, those threads were correct at the time.

:werd:

An 18 takes a LOT of room....as you can see from my sig....and I am still putting it in a 8cube ported box soon
