How to calculate resistance for a sub woofer
My 55 year old McIntosh MC-225 has speaker connections for 4, 8, or 16 Ohms. I use the standard speaker connections to connect to a Acoustech PL-200 subwoofer, which has in impedance of 8 Ohm. The PL-200 is connected to Focal 807v’s which are also 8 Ohm.
So what output should I use on the MC-225? I don’t know if the PL-200 connects to speakers in series or parallel (and the Acoustech support page doesn’t seem to work). Is there a standard way sub woofers work that I should assume?
I was using the 8 Ohm, but the amp died! Don’t know if this is related.
