roadster speaker impedance

[biller G]

hey all
Just picked up my roadster 212 combo ,great amp.
my dealer set it up for me and ran the speakers to the 16 ohm input.
i think it should be run to the 8 ohm conection but was hoping someone could confirm before i change it .Mesa tells me the 212's are 16 ohm speakers but i thought they were 2 8 ohms bringing the load 4 ohm

thanks in advance

If they are each 16 then plug them in the 8... if they are each 8 ohm then plug them in the 4.

Plug it into the 8 ohm for a 2x12.

well it all depends on if they are wired series or parallel. you will have to look at how they are wired and what the impedance of the speakers are.

Mesa uses 16 ohm speakers for the roadster...the amp had a 16, 8, and 2 4 ohm connections.

The 1 x 12 has 1x16 ohm speaker and uses the 16 ohm connection.

The 2 x 12 has 2x16 ohm speakers and uses the 8 ohm connection.

The roadster 2x12 cabinet is 8 ohm and when i plug that in with the amp speakers still connected, i use the two 4-ohm connections.

So, since you are just using the 2x12 combo you should be using the 8 ohm connection on the amp to the amps speakers.
