Mesa tt800 at 5.33 ohms?

[Rambo]

Have a cab at this impedance and was curious if it is safe to run this amp with it? If it's fine I'm assuming the 4ohm setting on the amp is the correct one?

 

[Arjank]

Is that the impedance (DC resistance) you've measured? If so then that is a 8 ohm cab.

More info would be better:

Where did you get that 5.33 Number?

From a meter testing the cab itself?

What cab is it?

How many speakers?

It is not its a 6x10 Cab with 8ohm speakers that are wired into 3 groups of 2 speakers in series.

It is a 6x10 cab I replaced the speakers on- it was very hard to source the odd impedance ones required to get a normal end result- so it is 8 ohm speakers wired in series parallel- (3 groups of 2 speakers in series) I get 5.33 ohm by dividing the impedance of each group (16) by the number of groups (3).

Then it's a 5.3 ohm cab like you already mentioned in the title.
Did you try it at 4 and 8 ohms? Which sounded better?

I recommend using the 4 ohm position on the amp.

Cool- thank you.

You're good. Solid state amps don't care if it's 4ohm or 100ohm. As long as you're above the minimum.

I would not risk running it at 8 Ohms. If your info is accurate, run it at 2 or 4 Ohms.

Because of the impedance/damping matching network on the TT's, it's better to set the impedance on the amp to the lower (4 ohm) position.

Epifani 310T cab is 5.3 ohms/750 watts. Found a used one for $350, might use it with a 800+
Is the power rating between the 800 watts at 4 ohms and 400 watts at 8 ohms?

Yes, somewhere around 600 watts.
