2 Sundown E15's / DCON 15's

[Chris Hammer]

I have a single SA-12 now....box already makes my back seat uncomfortable and I dont like driving people anyway...soooo

Looking to go to 2 15's. Lower power like GCON 15D4 or Sundown E15. I know its not earth shakers like the DC's and Nightshades you guys have going on but I have a fairly tight budget...(motocross/streetbikes take all my money )

Between the two I was looking at specs and noticed sundown list xmax as one way 12mm...SSA lists the DCON xmax as 16 but doesn't say one way. Do they normally list xmax as one way or does that mean the GCON has 8mm one way?

From specs which is suited batter for ported enclosure..I dont understand Qms Vas BL...but see some pretty big differences in their specs.

Will be run off my BRZ1200.1

What would you guys go with? I have pretty much unlimited space on box size so I can build optimal boxes for each? Any input on which would be louder/more low end/better SQ....just looking for opinions.

Also I'm not locked in on these....anything comparable that you have in mind please suggest it..
