But for hybrids like MLs, which Planckscale has, passive biamping has significant advantages.
Passive biamping an ML hybrid separates the stat from the woofer, thus presenting the amps with a less complex load.
The stat panel presents the amp a high impedance at low frequencies and very low impedance (1 to 2 ohms) at high frequencies. The woofer's impedance curve is relatively more flat. Driving them separately makes the amp's job much easier.
I biamp my Aeons with four of the five channels of my Meridian 5-channel amp. This makes the speakers more dynamic - a frequent complaint about hybrids is that they're not dynamic enough.
