I've always played out of an Ampeg V4b. Served me well for many years, but lately I've had an itch to get a proper, modern rig. I'm going to buy an Eden wt550, because I like the tone and options. I plan to pair that with a 410 cab. My question is, what are the differences in these 410 cab models, other than price, and wattage handling? D410XLT E410XST EX410 Are the EX models still made of plywood or do they use cheap mdf? Do they all use similar speakers, or are the EX speakers cheap? How big of a role do the added ports play? Thanks for your help.
