2x12 mesa speaker 8 ohms. Where to connect?

[metalmaster21]

Hi guys, i own a mesa 2x12 cab, with two vintage30 speakers. The impedance is 8 ohm, and on my mark V i see four inputs (two for 8 ohm and two for 4 ohm). I've heard that plugging the 8 ohm cab in a 4 ohm input it should sound better. Is it true?
Anyways, which is the most correct combination? I've read the manual, it says there are two 4 ohm inputs, one 8 ohm and one 16 ohm...So why there's just written 8 and 4? As you can see i'm not expert in these things! Please help me

Cut and paste from page 43 of the manual:
"Two 4 Ohm and two 8 Ohm jacks are provided for speaker interfacing. The MARK V is not very sensitive to speaker mismatches and will not be damaged by them, except that very low ohmage loads will cause the power tubes to wear faster. A single twelve-inch 8 Ohm speaker should generally be connected to an 8 Ohm output. When using two 8 Ohm speakers, connect them both to the 4 Ohm outputs provided (because the total load is 4 Ohms in that case.) Check out the information further back in this manual regarding speaker impedance and possible speaker hook-up schemes.
4x12 cabinets may be 4, 8 or 16 Ohms. If you are not sure of the impedance of your cabinet, you may need to remove the Rear Panel in order to verify the impedance rating of the individual speaker or speakers. MESA 4x12 and 4x10 cabinets come standard wired to 8 Ohms, and are wired in series-parallel. Some Non-MESA 4x12 cabinets are wired 16 Ohms using four 16 Ohm speakers. By wiring all four speakers in parallel, you can reduce the cabinet to an impedance load of 4 Ohms (assuming the speakers are 16 Ohms each.) No matter how unusual your speaker setup, it is always possible to get good performance."

Connect to 8ohms.
either combo or not combo... its the same!

MrMarkIII: you know the manual by heart heehhehehe
