GK 1001 RBII and a 300W (8 ohm) cab

[ValmiX]

Hi, are there contraindications if i use a 300W (8ohm) 1x12 cab with a GK 1001 RBII (460W 8 ohm)?
Are there risks for the cab (or the amp)?
I'm talking about using it with gain at 12 and master volume at 12 (maybe a bit more in extreme conditions) with a bit of boost.
I also but not always use a compressor to limit the signal.

thanks

I think you may have the volume a bit high for that cab. Does the speaker get farty? I can easily fart my 250 watt avatar neo 8 ohm 112 with a GK 400RB-III. I have to turn the bass down a bit for more volume. Maybe use the limiter on the amp?

its not good to overpower a cab, should just blow the cab rather than damage the head. theres a real good article as a sticky in amps, which is called overpowering and underpowering

The bad in the above is the premise of determining your settings without using your ears ...

You can run that amp with a cab rated for 10 watts safely IF you start low and bring it up slow and listen to it - When things start getting fuzzy or farty - you've gone too far and need to back down.

It's pretty dang simple...

i have the same head....and in my opinion, youve got the gain too high......i run my input gain at 9 oclock, my boost at 9oclock, and my master volume at 1 oclock......Cleeean tone for miles!!!!! but i guess that would depend on whether or not your using active/passive pickups......im obviously in the active dept.....

I don't see a problem with using a amp that has more power than the cabinet is rated. I mean the amp pushes 400+ watts, and the cabinet handles 300 watts, when are you going to push that much watts? If you need that kind of volume, I would think you are going to have Pa support. The extra wattage lets you get a good clean sound as you turn up without straining your head. I use the 800 RB and have never had to turn half way up, when I need that I'm going into the main, then my set up is just for stage volume.

That's an awful lot of amp for one little 12" speaker. If you need to be loud, you should be using a much bigger speaker box, like something with 4 10's or equivalent. What you've got going right now is almost a sure-fire recipe for blowing that 12" driver.

The question is how loud is he going to turn up? He has power to spare, and if he need more he can get another cabinet. That would give him a nice light wt stack that he should be able to do any gig with. I agree a 112 cabinet would not be enough for a rock band, but if he comes through the mains, he just need enough volume to hear himself on stage, the sound man will take care of the rest.

Invariably as the night goes on, the ears get tired and the crowd gets more rowdy the bands volume goes up. I too can see that little twelve giving up during the third set. A single 12 is, at best, a stage monitor. Using one on a gig is, IMO, courting disaster.

Amen!

[RickenBoogie]

Yeah.

[woody357]

I take it that you cats don't use the pa, and use your amp as backline, because if you did, you would know that the sound man would rather you keep your stage volume down and let him do the mix out front.

The problem with this statement is that it assumes that there actually IS a sound man or even a PA. Since coming to the Toronto area in the early Seventies I would guesstimate that ninety percent of the gigs I've played had no PA. Of the ten percent at least half what PA there was was completely incapable of handling a bass. A sound man was provided on very few gigs. Several of those the band was expected to pay for his services out of the gig money.

To me, that seems like a massive monster of a head for such a small cab. I guess to each their own and all that though. =]

I blew a 412 Marshall cab in less than 5 minutes with the same head. All depends on how loud you need to be. Obviously the Marshall wasn't loud enough for where I needed to be, or it wouldn't have blown. Effeciency is the key.

[johnk_10]

IMO, it'll work but it's way too much head for a single 12 cab. with your volume and master settings at noon, i wouldn't expect the speaker to last very long before you blow it.

Are there risks for the cab (or the amp)?

What specific cab and what genre of music, with what band configuration? FOH support, or no?

I rarely use more than a single 112 on my gigs, with anywhere from 180 to 600 watt amps working just fine for me. If more is needed, so is a different bass player, unless it's my own band. As always, it just depends...
