Connecting Multiple Speakers

If you must connect more than one speaker per channel, there are two methods in which to do so: Series or Parallel. Parallel connections are harder on the amplifier than series connections, as the total impedance is lower compared to driving a single speaker, and the amplifier must produce more current to drive them. The following diagrams show “bridged” connections from the amplifier. For more in depth information on series and parallel speaker connections, please visit the DAT website at www.diamondaudio.com
