genz STL-10T with shuttle 9!!! safe?

blakelock · #1 10-01-2010, 02:14 PM

hi all,
prolly getting a genz benz 10T cab (super light weight 10" cab rated at 200W/8ohm). i'm planning on powering it with my 500W shuttle 9. this should be ok as long as i'm very careful not to turn the volume up, right?

any other considerations?

Be very careful - simply reducing the master volume does not lower wattage. It's always pumping 500 watts @ 8ohms. Keep the preamp turned down and let your ears guide you.

NO!

Do some searches and you will see that GB themselves have said that these cabs were specifically designed to be used with the shuttle 3/6 heads.

They will not fair well with the power of the 9.

really????...hmmm...i was pretty sure that as you increased the volume knob, you were basically increasing the voltage output from the head. this voltage output is sent to the speakers. This voltage squared times the speaker impedance results in a delivered power.
Volt^2 x Imp = Watts

so the head has a max wattage it can deliver but would deliver far less at low volumes. i could be wrong though.

ps. ukiah, i'm definitely following your "ultimate 10" cab" thread. exactly what i'm looking for.

The master volume knob does not adjust the number of watts flowing through the system. It simply "attenuates" the signal, which is always flowing at the max. wattage @ 8 ohms.

Sure. Even when your not playing.

Anyway, just be careful, listen, and don't crank the low end.

That's not accurate at all - lower master does translate to lower wattage in the general sense that it takes less wattage to produce less volume. The amp is not constantly putting out 500 W.

You should be fine as long as you use some common sense with the bass knob and understand that 1) a single 10 is only going to be so loud, and 2) the Shuttle cabs were designed to be a little less bassy than the average cab (paraphrasing Genz here, so my terminology may be wrong).

I use a GK MB500 with a 4ohm 200 watt 1x10" cab. You just have to know the cab's limitations...but there is enough power on tab to smoke the driver if I let it.

You will want to use some real common sense, but the STL-110 cabinet is fine with the Shuttle 9.0.

By common sense, this means you will not want to use the LF boost (extend) feature, or much bass eq boost if you are playing at real volume.

It's not that we designed the cabinet to be less bassy, but that physics dictates that it's not goin to have the same low end as a larger cabinet using similar drivers and more extended tunings.

thanks a lot all,

i'm certainly only going to be using this system at low volumes (coffee-hous'in). i generally run my shuttle 9 EQ'd pretty flat and i love the tone so i won't be bass-boosting too much.

if i fry her, i'll give you all the gory details.

cheers.

Shouldn't be a problem.

I think what Ukiah is saying is that no matter what setting of the master volume the amp is still capable of its full output if the signal fed in is strong enough. In other words the master does nothing to curb the available output power, It just makes the amp need more input signal to get full output.

Yup, as long as you're sensible, it should be fine.

I use a STL-10T with my TC RH450 very happily for home practice & small gigs - works a treat. Obviously, like any gear, you need to respect it's limitations, but it's fantastic to be able to carry about so easily!

hey all,
so, i got the 10-T extension cab. i'm driving it with the shuttle 9 EQ'd flat, no boosts, pre-gain and pre-vol at ~noon. i've inched the final vol up to ~10 o'clock position. this is the loudest i've run it (active EBMM bass).

sounds pretty reasonable. i guess the cab is a bit mid present cuz i drop the mids on my bass a bit and play with my pluckers a little closer to the neck to get a nicer sound (i typically play a fEarful 12/6 with this head EQ'd the same). it certainly sounds loud enough for most coffeehouses and dining rooms.

since i have the extension cab, there's no frame on top, and the handle is in the way of the shuttle sitting flat. i'm thinking about bolting a frame on the side to mount the shuttle 9....

custom, baby!!

ps. i'll let you know if/how i fry anything with this big boy head on the little boy cab.

Yep, certainly loud enough, and can *just* keep up with a drummer & reasonably loud guitarists for practice. Think I'd just about get away with a pub gig, too, but that's what my NEOX 212T is for... Yes, it's a bit more mid-dy, and hasn't got full-on bass-extension - but it sounds waaay bigger than it has any right to. Always gets looks of amazements when people realise how small & light it is. I now travel (to practices at least) lighter than my guitarists!

And the nice thing about using it with the RH450 is that the feet on the head are *just* tall enough to make it sit over the handle, so no cludgy options required. I have to say, though, I do like the routed in handle approach that Ibanez take on the Promethean - think Genz Benz could do with following their lead there...
