QSC K12.2 vs HK Audio LINEAR 5 112 X

Short answer: the QSC K12.2. It ranks #1 of 50 12-inch pa speakers by sound quality, rated 4.7/5, at $899.99; the HK Audio LINEAR 5 112 X ranks #41, rated 3.5/5, at $899. Close enough in price that the sound-quality gap is the deciding factor.

Why pick the QSC K12.2: The strongest all-round tonal result in this popular-model group: the vendor Spinorama data produces a 7.73 ideal-subwoofer preference score and 48Hz measured bass extension. Watch for: The underlying Spinorama source is low quality, so its apparent measured lead deserves caution.

The case for the HK Audio LINEAR 5 112 X: High-quality manufacturer measurements give a 5.51 preference score with an ideal subwoofer and 0.63 predicted in-room smoothness. Watch for: It is designed as a top for use with a subwoofer: bass measures 103Hz at -3dB and about 67Hz at -10dB, and the standalone preference score is only 2.20.

Buy the QSC K12.2. It is rated higher for sound quality, and the $0.99 you would save on the HK Audio LINEAR 5 112 X does not close the gap.

QSC K12.2: $899.99 Amazon B&H Photo Video Guitar Center eBay

Pros: The strongest all-round tonal result in this popular-model group: the vendor Spinorama data produces a 7.73 ideal-subwoofer preference score and 48Hz measured bass extension. Extensive onboard DSP, flexible main/monitor use and a long market track record make it an unusually safe general-purpose choice. Measured bass extension of 48Hz (-3dB).

Cons: The underlying Spinorama source is low quality, so its apparent measured lead deserves caution. It is not the cheapest 12-inch option, and serious dance music or high-output live use still benefits from a subwoofer.

HK Audio LINEAR 5 112 X: $899.00 Passive B&H Photo Video eBay

Pros: High-quality manufacturer measurements give a 5.51 preference score with an ideal subwoofer and 0.63 predicted in-room smoothness. A 12-inch woofer and 1-inch compression driver on a rotatable 60° x 40° CD horn give a 135dB peak and long throw, and the birch and MDF cabinet doubles as a floor monitor. Measured bass extension of 103Hz (-3dB).

Cons: It is designed as a top for use with a subwoofer: bass measures 103Hz at -3dB and about 67Hz at -10dB, and the standalone preference score is only 2.20. A 3.1dB reference band and 0.625 listening-window deviation mean tonal balance is uneven. It is passive and needs an external amplifier, and B&H lists it as special order.
