#46 One Systems 212HC Passive eBay
Pros: The flattest on-axis response in this group (0.36dB average deviation in manufacturer measurements), with bass to 73Hz (-3dB) and about 51Hz (-10dB). Sensitivity of 99dB and 1,200W handling give high output for outdoor venues. Measured bass extension of 73Hz (-3dB).
Cons: Preference scores of 2.23 standalone and 4.88 with an ideal subwoofer trail its three-woofer 312HC sibling, and off-axis tone is less consistent. The 32.8kg cabinet has a narrow 60° pattern. It is passive and sold through pro dealers with no published price.
How it compares: Just above it: HK Audio LINEAR 5 112 X. Just below it: PreSonus CDL12.
