Any resistance or inductance in the trace between the device and the capacitor can cause a loss in efficiency Using speakers more resistive than 4-Ω dramatically increases the thermal performance by reducing the output current and increasing the efficiency of the amplifier. Note on speaker choice (4/8/16/32 ohm, etc.): The audio input pins (INR+/- and INL+/-) must run side-by-side to maximize common-mode noise cancellation.
