Short answer: the Axiom ED120A. It ranks #18 of 78 12-inch pa speakers by sound quality, rated 4.0/5, at $1,790; the Seeburg X6 ranks #23, rated 3.9/5, and costs $1,975, so there is not much of a tradeoff to weigh.
The Axiom ED120A is the deeper-bass option. High-quality vendor Spinorama data gives it a 5.73 ideal-subwoofer preference score and 52Hz bass extension, a solid tonal showing for a professional cabinet. Its bass reaches about 60Hz before falling 3dB, against 80Hz for the Seeburg X6. The tradeoff: The 132dB claimed peak is competitive rather than class-leading, and the asymmetric 60°-to-100° pattern needs more deliberate aiming than a conventional symmetric horn.
Why pick the Seeburg X6: Manufacturer measurements give preference scores of 3.07 standalone and 6.04 with an ideal subwoofer, on par with the JBL PRX912. Watch for: Bass reaches 80Hz at -3dB and about 66Hz at -10dB, so a subwoofer is still needed for full-range music.
Buy the Axiom ED120A. It is rated higher for sound quality than the Seeburg X6 and costs less, so it is the default pick unless a specific strength of the other one matters more to you.

Frequency Response Compared
Both speakers’ spinorama measurements, overlaid. A flatter line is more neutral: peaks sound forward or harsh, dips sound recessed. Each curve is shifted so its average from 300 Hz to 3 kHz sits at 0 dB, so loudness differences between the two are removed and only the shape is compared.

Axiom ED120A: $1,790 eBay
Same family: the Axiom ED60P (smaller model, rated 3.3/5), the Axiom ED80P (smaller model, rated 3.4/5) and the Axiom ED150A (larger model, rated 3.8/5).
Pros: High-quality vendor Spinorama data gives it a 5.73 ideal-subwoofer preference score and 52Hz bass extension, a solid tonal showing for a professional cabinet. CORE DSP, PRONET remote control and an asymmetric rotatable horn add useful installation flexibility. Measured bass extension of 60Hz (-3dB).
Cons: The 132dB claimed peak is competitive rather than class-leading, and the asymmetric 60°-to-100° pattern needs more deliberate aiming than a conventional symmetric horn. Availability and service coverage are less broad than the mainstream QSC, JBL, Yamaha and RCF choices.

Seeburg X6: $1,975 Passive Thomann $1,975 eBay
Same family: the Seeburg X1 (smaller model, rated 3.4/5), the Seeburg X2 (smaller model, rated 3.6/5), the Seeburg X4 (smaller model, rated 3.9/5) and the Seeburg X8 (larger model, rated 3.5/5).
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.
