Stumpy is one of the few RDA's that I haven't switched over to "bought" coils - I still use simple, single-wire coils, dual, probably netting out at 0.4 (yes - for the pair, lol) ohms or so. If I recall correctly...So 1st go with the stumpy cap gets hot, like screaming hot. Very non aggressive build, 2x 27g K 36g N80 fused claps @ .24. Will certainly do some playing around, but any thoughts from the stumpy users? I am not against using it single coil, just doesn't look like the best design for that?
I'll check, but I ate a sub made for two people, and I can't get up right now.
