For best performance, configurations shown in

should be avoided unless a strict budget dictates otherwise.

Although Martin Audio MA and E Series power amplifiers work well down to 2 ohms, other power
amplifiers often suffer sonic degradation or, worse still, shut down into low impedances. Always
check your intended power amplifier’s specifications and conduct listening tests before committing
to a very low impedance system design.
