Just bought the GK 700RB-ii at Sam Ash today... haven't fully-decided on the cab(s) yet, plus I still need to save up $ for that purchase. I've been trying out a bunch of different-sized 10''s and 15''s, half/full-stacks... haven't found any 12''-speaker cabs in stores until today. The Sam Ash by me just got in a ''used'' GK Neo 4x12 recently, and they're selling for only $550 (which is like half-price of what the new ones cost, and naturally caught my eye). I didn't have time to try it out today, but I noticed that the cab's power handling is 1200W (yes, quite the monster, indeed) @ 4 ohms. With the GK head, I have the option of running either one 4-ohm cabinet @ 480W/50W or two 8-ohm cabs (in which case a lay-person such as myself would assume the wattage coming from the head is split evenly to 240W/25W between both cabs, but I have a feeling I'm dead wrong about that). Anyways- so far, in almost all of the rigs/setups I've demoed at different stores, the cabs I tried were specified with a power-handling "roughly" similar to the wattage listed on each of the heads. That's obviously not surprising since most floor-rigs you see at the stores are set up for the head to be used with only the 1 or 2 cabs sitting right next to or under it. From what I understand, the powerhandling (wattage) advertised on a bass cab is pretty misleading and often not very meaningful by itself, but I'd like to know if there's any reason that running a 480W/50W head thru a 1200W cabinet would be a bad idea? I realize that this question has arisen in previous threads, but I couldn't get a clear answer from ones I read (or from the guys working at SamAsh today). Any replies are very much appreciated, thanks!
