Ok, so I'm looking for opinions. I know there's a lot of them out there, so let's hear 'em! I recently purchased an Ashdown EB 12-180 and must say that I'm a very happy camper. Best darn bang for buck amp that I could hope for. However, now I'm lusting after an extension cab so that I can use the whole 180w... decisions, decisions. Should I get a 210, 410, or 115 cab? But wait, there is more to consider... I anticipate getting a new head eventually (maybe a MAG but hopefully an ABM) and so I want to plan for this now and the cab will have to do double duty. Ultimately I anticipate that my desired rig would contain, at least, a 210 over a 115. But I can't afford to get both cabs immediately, so which one would be better to buy now so that I could also use it with my combo immediately? Also, if I'm considering a 210, is there any reason that I shouldn't consider going a little further and doing a 410? Pros/cons anyone? By the way, I'm mainly looking at MAG cabs right now. And finally... Since my bigger rig would be more powerful (575w minimum) I'll have to make sure that the cab I choose will be capable of handling the larger wattage. However, I once heard (and I'm not sure if I understood correctly) that if a driver that is rated for higher wattage is also harder for a smaller amp to push (stiffer cones, or something???). So if I were to get a 410 cab with a 600w rating, and tried to use it as an ext. cab for my 180w combo would it really do any good? Would the amp handle it? Would I have to worry about underpowering the cab and damaging the drivers? If so, maybe a 115 cab with a 200w rating (or 210 with 250) would be better for now. I realize that I've actually asked a lot of questions an introduced a lot of variables and have created a scenario with lots of possible outcomes. That's part of my point in this post (and part of the fun), I want to hear your opinions, experiences, and pros/cons. Its not enough for me to know what you think is best, I'd like to know why, as well. Thanks! p.s. Is there anyone out there who will claim that the EB12-180 (with a ext. cab) is actually a sufficient rig in and of itself (or am I dreaming)? If someone could make a valid argument for that, then I'd perhaps only buy a second 112 combo (avatar perhaps). I know, one more variable to consider... but while the possibilities seem endless, unfortunately my cash supply is not, so I have to buy wisely.
