Got some clips of the Force 12's in the XXX cab. They definitely sound less "on-axis" than the other clips I mentioned but haven't posted. For now, here are the V30 and Force 12 clips for the XXX slant 4x12. I think I need to start re-amping or looping a riff for this, playing variations like how hard I hit the strings seems to make a significant difference based on several takes I got, so that's going to obscure inherent speaker differences. Not to mention the slop.
For this pair I really like the Force 12.
I'm not particularly fond of either of these following clips. I think the V30 sounds mostly better, though the Force feels like there's just a little something missing for me to like it best. I think if I whacked the strings harder I would have got a "yowl" that completed things for me.
Rig was Schecter Reaper 6 into '82 2204: Pre 7, Master 10, Treble 10, Mids 10, Bass 0, Presence 5. I had a Fryette PS100 to tame the volume, and I had it up loud enough to not notice string noise on playback of the recordings, though I hear a little now. Cabinet was a Peavey XXX slant 4x12 "detuned", with each speaker pair getting put in the top slots and covered with mitchell donut beam blockers. Mics were a PZM wedge stereo array with the PZMs level with the cone centers. Only post-processing was an EQ bus to flatten out the PZM's HF peak.
