When it comes to weight, its not a concerning factor as I do not have a fridge. I only have an Ampeg SVT 210HE. So its only a 2 by 10. Just swapped it for a TC electronic cab. This means I wouldn't have to put it on top of a fridge and just put it on waist height. Using the cab sideways up. This makes it easier to move everything around. The head I am putting it through is an early SVT 3 Pro as shown at the bottom. This weighs a total of 11 Kilograms, 7 lighter than the 400+. Which to think about isn't much.
The tones are similar but I think my SVT misses that scoop on the top that just edges the SVT.
Funny you should mention Eden, I have tried them when I didn't know what it was. And it was not what I was looking for at all. Out the three I tried (Where I didn't know which was which) Ampeg, Eden and Aguilar. The Ampeg came first, with the Aggie second and the Eden last. It was too muffled in comparison. I do like clarity and scoop sound. I know you cannot really account it to the cab. Its down to the head as well.
