Short answer: the DAS Audio Vantec 15A. It ranks #46 of 62 15-inch pa speakers by sound quality, rated 3.1/5, at $1,818.99; the JBL SRX835P ranks #52, rated 3.0/5, and costs $2,499, which makes this an easy call rather than a real tradeoff.
Why pick the DAS Audio Vantec 15A: Medium-quality vendor data shows 52Hz measured extension, and its 90° x 50° coverage and 135dB claimed peak carry over the DAS Audio Vantec 12A’s Class-D amplification and Bluetooth control into a 15-inch cabinet. It keeps a wired aux input, which the JBL SRX835P lacks. The tradeoff: The 2.87 ideal-subwoofer preference score is one of the lower results in this ranking, well below the DAS Audio Vantec 12A’s own measured result.
The JBL SRX835P is the more accurate, deeper-bass pick. A powered three-way PA speaker from JBL Professional with a 15” woofer, a midrange and a compression driver on a horn, rated at 2,000W. Its measured preference score, a predictor of how neutral it sounds, is 2.01 against 0.45 for the DAS Audio Vantec 15A. Its bass reaches about 39.6Hz before falling 3dB, against 56Hz for the DAS Audio Vantec 15A. Watch for: Audio Science Review found an uneven response (1.70 average on-axis deviation).
Buy the DAS Audio Vantec 15A. It is rated higher for sound quality than the JBL SRX835P 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. The two were measured by different sources, so small differences, especially in the bass, can come from the measurement setup rather than the speakers.
