Short answer: the NX 912-A for raw amplification and build, the Vantec 12A for Bluetooth and an onboard mixer. These rank #38 and #20 out of 83 12-inch powered PA speakers, priced at $1,645.99 and $1,449, a $196.99 gap.
The Vantec 12A is feature-rich but measures below the category leaders. The 135dB claimed peak, 90° x 50° coverage, FIR processing, onboard mixer and Bluetooth audio make this a feature-rich event cabinet. Medium-quality vendor data shows a 3.40 ideal-subwoofer preference score and about 68Hz bass extension, a below-average measured tonal result for this ranking. Bluetooth is useful for convenience playback, but wired inputs remain preferable for reliable low-latency production audio, and at 47.4 lbs (21.5 kg) the plywood cabinet is not especially light.
The NX 912-A has more amplifier power and a wider horn, but no confirmed measurement. Its plywood enclosure, 2100W amplification, FiRPHASE/Bass Motion Control and flexible rigging make it a sturdier systems alternative to the ART 912-A, with medium-quality data indicating extension to roughly 58Hz and broad 100° x 60° coverage. The truncated vendor measurement doesn’t yield a preference score, though, and its 130dB peak claim matches rather than exceeds the cheaper ART 912-A.
What the Vantec 12A adds:
- Bluetooth audio streaming and DASlink app control, absent on the NX 912-A.
- An onboard mixer with 2 XLR mic/line inputs plus a 3.5mm aux input.
- FIR-based processing alongside standard EQ and delay.
What the NX 912-A adds:
- More total amplifier power, 2100W peak versus the Vantec’s 1500W peak.
- A wider 100° x 60° coverage pattern, versus the Vantec’s 90° x 50°.
- 6 x M10 fly points for permanent rigging versus the Vantec’s simpler M10 mounting.
Buy the NX 912-A if you want more amplification and a wider dispersion pattern for systems use.
Buy the Vantec 12A if an onboard mixer and Bluetooth convenience matter more than the strongest measured tonal result.

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.
