Haha, I can vouch for that. I've moved mine at least 2400km in roughly the same period. Everything still works great and I push these speakers pretty hard... They play probably at least for 10 hours a day. Never regretted getting them for an instant. They even fell once while I was carrying the 30kg box downstairs - luckily on top of me so they didn't get damaged, although my foot ligaments were torn in the process. Haha, small price to pay. Only problem I've had is a blown fuse and some backlight issues which seemed to fix itself since it's fine now. Probably a dry soldering joint or something.
