I almost jumped to the Wizard/Governor combo in my sealed 2x12 for my Fuchs BJ21 but I'm wondering if a lower wattage speaker combo would be better for this 21 watt amp. My amp itself does not put out heavy distortion but I use a variety of pedals for medium to heavy distortion and also heavy stoner fuzz. The Wizard/Governor combo will give me a 150 watt cab, I think the RF/CR will give me like 60 watts or so. I've read where the RF does well except with heavy distortion but I've also read it handles it just fine in a closed back cab. I wish I had all these speakers at my disposal to try before buy!!!!
