Will 2 Eden D-410XLTs perform the same as the Eden D-810 XLT? Or better yet, if you put a D-410 XST, upside down on top of a D-410XLT that is on it's side, all the drivers will be very close to each other, closer than the 8-10 or 2- 410s stacked normally. I'm looking to try to emulate what an Ampeg 8-10 does with my 71 SVT head, but with Eden cabs. I'm tryin to get more punch with the 300 watt tube head. Currently I use a 4-10XLT and 2-10XLT and some rooms are punchier than others. Also, does the the fact that Eden uses ports, and high power drivers, make the damping factor slower than a sealed 8-10 with lighter drivers. I really don't want to, and can't lug an 8-10 around. I hope I'm being clear.
