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 Seeburg X6 ranks #22, rated 3.9/5, and costs $1,975, so there is not much of a tradeoff to weigh.
What the QSC K12.2 does well: 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. The catch: The underlying Spinorama source is low quality, so its apparent measured lead deserves caution.
What the Seeburg X6 does well: Manufacturer measurements give preference scores of 3.07 standalone and 6.04 with an ideal subwoofer, on par with the JBL PRX912. The tradeoff: Bass reaches 80Hz at -3dB and about 66Hz at -10dB, so a subwoofer is still needed for full-range music.
Buy the QSC K12.2. It is rated higher for sound quality than the Seeburg X6 and costs less, which makes it the one to get unless you need something the other one does better.

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.

Seeburg X6: $1,975 Passive Thomann eBay
Pros: Manufacturer measurements give preference scores of 3.07 standalone and 6.04 with an ideal subwoofer, on par with the JBL PRX912. The coaxial 12-inch woofer and 1.4-inch compression driver give a 2.2dB reference band and consistent sound across the 80° x 60° pattern. With 99dB sensitivity and a 131dB peak rating from an 18.5kg cabinet, it suits bands and venues that need output without bulk. Measured bass extension of 80Hz (-3dB).
Cons: Bass reaches 80Hz at -3dB and about 66Hz at -10dB, so a subwoofer is still needed for full-range music. It is passive, so you need an amplifier and a processor with Seeburg presets, or the self-powered X6 dp version. A 4.34 directivity-index deviation means off-axis balance shifts more than the flattest designs here.
