This is juuuuust a little too much of a blanket. While there definitely are benefits, it’s much more complicated than that. Iirc that JBL driver thread came about because of the BOSS?Check out the $29 JBL 12 thread on avsforum.com. The last couple pages we are discussing 1 sub vs 4 subs. If WAF is not an issue, then 4 subs moving 1mm is better than 1 sub moving 12mm in simple sealed enclosures.
