    Not sure if I'm reading this correctly. Does R6 represent the driver? Or is that a real resistor?

    Also, are 10 watt resistors suitable for application? Or should I double the value and run two in...

    Thanks 4313B, that's what I meant.

    I think I'm going to use the N4671 lo pass filter as I'm using the 2035HPL which doesn't seem to need the zobel. I measured the imp of mine a while back and...

    Aftermarket, about $30ea. Thought I would try them, given the cost of the jbl parts.
