you could be correct as Ive not heard the unit in this post, but was going by sub woofer size.
I know that 6' subs if powered right can hit decently. but certainly not as hard as an 8" sub powered right
I guess it depends on who designed it :)
there is also the difference between cab sizes. the BOSE tends to be used in a more open cab. that said, it did sound exactly like you stated, even in the cab of my ranger, nice deep bass, but never hit hard.
