I have a pair of a/d/s 400L's. They are an excellent little speaker. They have a 6.5" driver and a 1" soft dome tweet. (detailed but smooth) I run these with a sub. They are rated at 4 ohms. Will bi-wiring make much difference? Can yhou even bi-wire a 4 ohm speaker? It seems since they don't handle much of the bass info that bi-wiring would be a waist. Is there any info to separate?
