I know a solid nobel network and overbuilt amp is the key to driving low impedance loads however i am not keen on using an inductor in my amp for various reasons. I know ICs can act as a zobel without the inductance or emi/rfi potential issues as well as some transistors. What can be done in place of a zobel at the amp level and since my amps are built to pair specifically with my speakers, can i use a zobel on the speaker ins prior to the XO for same results? Most designs are using active crossing with bi/tri amping depending on the speaker array. for the rack mount version, what can be done to eliminate the need for an inductor? I would like to be stable at 2 ohms with possibility of 1 ohm stability.
