Can you play an AVT150h through an MG412 cab?

Bucknasty · 09-07-2008, 05:44 PM

I have an MG100HDFX half stack and I'm wanting to upgrade to the avt150h can I still use the MG412 cab?

I dont see why not?

Bucknasty · 09-07-2008, 05:56 PM

yeah it's the 120 watt version 4x12.

those avt150 seem way cool...i could go for that,,,,avt50 da boss amp!

You can but don't go to full volume. The AVT150h is a 150 watt head, the MG412 is a 120 watt cabinet, the head on close to full volume would likely blow your speakers.

I've also been thinkin about puttin some verteran 30's in there.

Its OK - AVT150s only put out 150W into a 4Ohm load, which means two cabs. Anyway, they have soild state output sections, which you do not drive to the limit, (unlike all tubes amp) because they will sound nasty. So long as they are sounding good, the power is less than max.

check your running the right impedance and as somebody else already said cause of the differece in volume dont run it full tilt!

this is a subject close to my heart actually can anybody suggest something for me??

i run the avt150 head at the moment through a jcm 800 lead series cab that is 16 ohm

the avt when driving a single cab is 8 ohm out put,

the limited theory knowledge i know would sugest that with the resistance of the speaker being twice the output of my amp, its having to work harder to drive this speaker

is there any way to rewire to make my cab 8 ohm????

or any sugestions?????

The avt amps, with their solid state output sections, are perfectly happy driving higher Ohms loads, you just dont get quite as much output than it can push into 8 or 4 ohms. No need for you to change anything if it sounds good.

Its actually not possible to rewire 4 16 Ohm speakers (as you have) to make 8 Ohms. The only other sensible option is all in parallel to make 4 Ohms. The AVT head can actually drive a 4Ohm load, at which it will give its max 150W power. It will be working harder however, so if its OK now I'd keep your cab as it is.
