Do you guys have an opinion if 4x12s sound spikier in the highs vs. a closed back 2x12 or 1x12 with the same speakers? Is there a physics behind one of these size cabs sounding smoother or spikier when listening directly in front of the cabinet listening at speaker level? Yes, I've tried beam blockers, tone bras, and different speakers. This is a question about the nature of a 4x12 vs 2x12 vs 1x12 sounding harder or spikier in the highs when right in front of the cabinet. Thanks!
