No way the Meridian will do 118 db at 18Hz. I could do that with my old system but it had 32 12" woofers. I ran that for quite some time and still miss my old speakers (Infinity IRS V mains, IRS Betas for surrounds and IRS Gamma for a center channel) but it is a rare system that doesn't need a sub.
Certainly there are more people who think they don't need a sub than ones who actually don't need a sub.
