Which of these subwoofer can produce a deeper lower base? (SEE INSIDE)?

i am looking for a subwoofer with base so low just like the one in the movie theaters that shakes your whole body... best if they can shake windows & floor too.. which of these is closer to doing it?

JBL Venue Series SUB12 12-Inch

OR

Sony's SAW3800 15" Subwoofer

If those are your only 2 choices go with the Sony sub

The JBL sub has 300 watts rms but the frequency only goes down to 50 Hz while the Sony goes to 20 Hz but has 250 watts rms

.the lower the frequency range, the deeper the bass. Neither of the "sub"s you mentioned have earned the right to be called SUB-woofers. Both will do an acceptable job of reproducing upper bass. Nether ventures into the sub-bass frequencies. I'd suggest you look at HSU, SVS, or for an entry level sub the Acoustech H-100. It gets just barely low enough to be called a sub-woofer. It will dig down to 27Hz which is a true sub frequency but it falls off very quickly after that. However it is very reasonably priced (I got mine for $230 including shipping) and it will give you a taste of real sub frequencies. dumpthem both get a plok audio 12 inch
