need to know asap

iv seen alot of post about the GK 1001RB II head on here by none about the problem im having. see i have a GK 4x10 cab and a GK 1x15 the 4x10 is 400 watts and the 1X15 is only 200 watts both at 8 ohms.. ok so if i get this head that puts out 700 watts at 4 ohms will it damage my rig if its sitting at 600 watts at 4 ohms? or is that how it works? or should i get another cab that sits at 400 watts?

It has been covered a ton on here. Check out the links at the top of the forum. The short answer is that the head won't put out consistant 600 watts into your cabs. Regardless of that, it is in fact better to have a head with more power than your cabinets. Just use common sense when playing through them so that you aren't over extending. I put 500 watts through my 300 watt Mesa cab all the time and it sounds great. Just use your ears/eyes. You'll be fine. That should be a killer sounding rig.

Technically speaking, your 1X15 and 4X10 rig will only have a capacity of 400 watts because the wattage from your head is split evenly between the 2 cabs. therefore, since the weak link in the chain is the 200 watt 1X15, you would double that amount (because of 2 cabs) to find your limit.

Even more technical - that rating is only a thermal rating for the voice coil in the speaker to melt. It has nothing to do with real world power handling capabilities. *MOST* speakers run out of gas around 50% of their thermal ratings due to mechanical limitations.

If your 1x15 and the 4x10 are both 8 ohms, you can run them together. Your load will be 4 ohms. The 1x15 might not handle the wattage.

Watts are a minor concern. But the fifteen is the weak link, not only with respect to watts but also excursion. Two matched 410s will work better than a 410/115 nine times out of ten.

I would add a caveat. If you are using a compressor or overdrive pedal this will increase your average level. Also if you crank up the bass knob a lot, so yes the 700 watts could get you in the danger zone.
ANother thing to consider is that your 22 watt cab will likely run out of headroom before your 400 watt cab, so in reality you dont have 600 watts of speakers, you have 400 watts.

I thought questions like this were answered in some of your other threads, but...........

Your 410 is a Goldline, right? Those are cheap drivers in there and can be totally destroyed by the power of a 1001.

I disagree. Sure, if you want clean headroom, you'll be wanting a lot of power. But I think it's also best to have cabs that can take as much of a pounding as possible. For clean headroom guys, I would think that the ideal scenario would be to have a head powerful enough so that it was never clipping no matter how loud you needed it, and speakers rated high enough that there was never much danger of farting out.

that all depends if the op is sensible or dopey, though. the more wattage than the cab can handle thing is from pro audio circles to keep clipping from blowing expensive tweeter horns, but most pro audio guys know what they're doing. the average bass player doesn't

so you listen to the cab for signs that it's struggling, and you turn down when you do.

Yes.

Well, if you needed to know ASAP, then I'd offer a few suggestions....

A. Type in a manner that makes it easy to read your post. Put in capital letters, attempt correct punctuation, etc.

B. Search the forum first for the answers- especially this one. It's been done to death.

Bottom line is, the amp doesn't "sit" at any watts. It's capable of delivering up to 700 WRMS @ 4 ohms. The two cabinets are rated at 8 oms so both together will put a 4 ohm load on the amp. The amp will be safe (because 4 is the minimum) and it will be able to give you up to 700 WRMS. The cabinets are rated at 600 watts total thermal power handling. That spec is essentially meaningless. Basically it only tells you where the voice coil will melt. You'll most likely destroy the speaker well before the voice coil melts. The cabinets don't draw power from the amp, they only react to the power the amp sends to them. So, if you like the sound of those two particular cabinets together^* they'll work fine for you.

Could it be better? Yeah, a pair of 4x10 (both 8 ohms, and even better if they're the same model cabinet) will give you a much larger sound and give you much better control than a woefully mis-matched rig like a 4x10 and a 1x15. But there are a lot of threads here that go into that discussion so we don't need to rehash the reasons here.

Just don't assume the 1x15 is adding any particular lows that the 4x10 don't have. Any noticeable increase in low end is generally only because you're moving more air with the second cabinet. Just about ANY other cabinet would add low end and volume. It's not because it's a 15, it's because it's more speaker moving more air. That's why another 4x10 is generally considered to be better.
