would a bottom firing sub have the same room harmonics as a front firing sub ?

would a sub with a 8" woofer have the same room harmonics as a sub with a 12" woofer ?

maybe the 'ease of placement' is dependent on these and/or other variables ?

I can say i had to do the subwoofer crawl to get the flattest response in my squarish room with EP175.
