Thanks for responding. To me it is strange that a 15 would behave so much more significantly different sealed than a 12 sealed. I heard someone else mention that too. I came across just one DCON owner in forums that went sealed, he says he is very impressed then someone responds after him saying he tried sealed and it was very disappointing. On top of that 99.9% of the rest of the DCON owners seem to go ported and say sealed isn't good with this model SSA woofer when it gets brought up. So that's my dilemma. Not seeing any love for sealed at all. I would consider going down to 2 subs ported if I am convinced that 2 ported is equally loud / performing than 3 subs sealed. I think it would be a tight fit in the area of my ride not sure yet. http://tl.acurazine.com/forums/showthread.php?t=780416 I will research cabin gain that is new to me. Looks like a interesting read. As far as how the Kickers are behaving, I am very happy with them SPL wise and I want to not sacrifice very much of that when switching to DCON sealed. I was actually hoping to be a little bit louder than the Kickers but I can live with the same levels if that's how DCONS perform. I am simply looking to add the cleaner bass component and lower end notes as Kickers are known crap out in that area. I regret selling my JL Audio W6's as I would be totally content if I still had them. Even if they would be 15 years old by now. These DCONs remind me heavily of that old JL model because it was a 300 watt SQ sub but could suck the snot out your nose and blur vision at the same time. That is what I am looking for with the wattage and price point. Here is the space I am working with that I want to stay close to. It can hold a little bigger. I haven't done official measurements yet but I am pretty confident 3 12's can fit in there.
Would the RE Audio SRX be a better choice sealed than a DCON sealed? I appreciate it.
