Hi, hope someone can help me out. I've got a Traynor YBA-1a (4ohms) I'd like to run through both a 6x10 (5.3 ohms) and a single 15 (8 ohms). I believe in parallel this comes out to 3.19 ohms. I know you aren't supposed to run a head into a lesser-ohm cabinet (like an 8 ohm head into a 4 ohm cab), but would this rule apply in this situation, where the difference is not even 1 ohm? Thanks for any info.
