I'm looking to purchase a new Traditional Avatar 2x12 (semi open oval back) with Celestion Golds. In general is it preferable to purchase two 8 ohm speakers vs. two 16 ohm speakers? I was thinking of using 8 ohm speakers because 8 ohms seems much more common and flexible for mixing/matching with other cabs and amps. Then the question is: series or parallel? Do you recommend getting the Avatar multi-jack with two 8 ohm speakers? Then I can get 4 ohm mono (parallel I assume), 16 ohm mono (series?) or stereo (which I will never use). What do you guys think of the PCB multi-jack vs. just the standard Avatar mono jacks? Also is there much risk in running a series configuration? I understand if one of the speakers blow then the amp will not see a load at all in series config.
