[QUOTE="VereChronicus, post: 1493759, member: 565864"] That is what SOME have said. The way to really "try" to compare is to take a look at super high dollar home audio systems. The subwoofers come in both ported and sealed offerings. To move the piston as LITTLE as possible is the name of the game when it comes to distortion, so tons of surface area makes output possible with little excursion. Most larger subs have extreme mass to go along with them, so most companies stick with 15's 12's and 10's. Servo controlled systems do the job well also. Martin Logan broke out a big *** system that utilizes a bunch of 12" subwoofers in sealed enclosures. Tight impact and very good low frequency extension with tons of cone area making excursion very minimal to achieve high output. To think that "a ported enclosure" cannot track with heavy metal kick drums only comes from a particular A/B comparison that someone may have made. Not all sealed applications will fit into "A" nor all ported into "B". The guys that own Rainbow use a pair of DD 3512's in a ported enclosure in their SQ demo vehicle in Germany. There is truth to one being better than the other via personal preference, but it is only true to yourself. I've got a personal preference for multiple TL enclosures as well as ELF circuitry running multiple smaller drivers. My home system consists of two 4.5" wide x 8.5" long x 48" tall that each house (8) 6.5's. That is the cone area of (2) 18" subwoofers with the speed of 6.5's. Pure cone area along with the Bagend ELF circuit enables them to hit blue whale ejaculation frequencies. I'm all 'bout it-bout it' if it gets fairly low and loud and can track with Neil Peart and Mike Portnoy when they're pissed off. [/QUOTE]
