I was bored today and I tookout my Radioshack SPL meter to see what my new subwoofer can do, and with today's hiphop music (say Freek-A-Leek by Petey Pablo) I was getting an average reading of 120dB+, from a bit below 40Hz up to 60 some Hz, at my listening position, which is on my bed. This is with the meter set at C weighting(for frequencies 32~10000), at 120dB with the SLOW setting. I did the same test again at 20Hz and I got a little over 100dB. I thought 120dB is supposed to be pretty hard to get in home audio? My sub setup is a home built box, a P.Miller series 12" sub and an old Technics integrated amp, the whole thing costs me about 160 bucks.

So this subwoofer setup I threw together in a few minutes is louder than most sub-1000 dollar powered subs? Correct me if I'm wrong

The other pic is what I used to have...two twin 10" towers and a dual 15" tower off a Proton D1200. Who knows what SPL that was...
