All the way up... danger Will Robinson?

[Kitsho]

I'd like to know if I can turn up my GK MB112 all the way (including EQ)
without worry, using a passive bass. Are these amps designed
to withstand full volume without damage? Juss wonderin'....

There's no way to answer that question. Every bass has a different amount of gain so who knows, but my guess is that you're asking for disaster.

Listen to it.

The speaker will sound different as you get "too" loud, and eventually different will turn into dead.

You should consider the cab usable right up until the "sound different" point, and then back down.

One of the craziest questions I've seen on TB!!

I just still don't get it.....Why people buy inexpensive, single speaker combos that are little more than practice amps, then want to push 'em like an SVT.

They can afford that, they are at a playing level that they think that's what they should buy, they watch MTV etc. and dream, they haven't put in the time to bring out the music .

Who said anything about wanting to? Its a reasonable question.
If the amp or speaker can't handle the parameters it was designed for,
then why design it that way? Am I supposed to assume that everything that is made can't handle the limits for which its made? I had a Peavey
bass amp that could play at full volume for hours. Heartley Peavey knows how to design amps that can HANDLE FULL VOLUME. Why did I run the amp at full volume? Because it was a lower wattage amp in a live band situation. **** happens.

7 posts and already with the swearing.

Kitsho, step back a bit and take a breath. You just got here and said you had a lot to learn, which you won't be able to do if you bristle so easily. We might have a lot to learn from you, too. It would be a shame if you flamed out so spectacularly from the tiniest of perceived slights.

So, by watching MTV, lesser bassists think a single speaker combo is what they should buy.

I get what your saying, but you said it poorly.

Hey, Kitsho, don't damn us all from one response. The forum allows for all types and opinions and if you post on it you are going to get a wide variety of responses, although I can understand why you feel offended. For what it's worth, I have only ever owned one combo that I could crank all the way and that was many years ago, a Peavey Databass I think it was called. It must have been one of the first digital amps, anyway it monitored and controlled the speaker excursion to keep it safe - so logically I suppose it is feasible that modern research can do the same if a manufacturer wants to include it. Unfortunately I don't know if this is the case with your GK, ultimately your ears will tell you if the speaker is overworked. Keep smiling, buddy

Specs mean nothing.

That wasn't a mistake. Specs mean nothing.

When it sounds like it's having problems, turn it down.

i wouldnt do it cranking your amp can cause the amp to clip which blows speakers even with speaker protection circuitry. I wouldnt do it upgrade your amp and cab if you want to crank it, or crank it and blow yours its your money your going to have to give to a tech to fix it or buy a new one.

Yes mate you are in luck!, the GK MB112 is along with all other GK equipment, designed specifically to be totally idiot proof.
No matter what sort of horrendous buzzy farty noise you find the amplifier makes when dime'd rest assured there is nobody stupid enough or insensitive enough to actually damage one.
We tried sending one to the bloke that thought it was a brilliant bit of foreign policy to report the execution of an unarmed terrorist leader rather than simply claim that he had taken his own life to avoid capture.
Special testing sessions are also carried out by well qualified participants from West Virginia otherwise appearing on the
Jerry Springer show.
Since The maximum output level of a bass guitars jack socket varies between 100 mV rms to well over 1 V rms for some of the higher output active types.
It has been found that using a dime'd musicman stingray active in the passive input gets well over 10 times as loud as an old dan electro with passive lipstick pickups + the value of the -&db active pad which can be calculated very simply (other than by US foreign policy gurus and Jerry Springer show guests) by following this simple equation:
Voltage dB are calculated as
dB = 20 log(v/V) where log is the common (base 10) log, v is output, and V is input. So
30 = 20 log(v/V)
3/2 = log(v/V)
10^(3/2) = v/V = √1000 = 31.622 so
v = 31.622*V
Anything else you need to be made aware of.

PS The only Knob position that has any finite bearing on anything at all without knowing the input voltage, is the side a gentleman dresses.
