Short answer: the JBL Stage 250B. It ranks #97 of 179 bookshelf speakers by sound quality, rated 3.2/5, at $439.95; the Definitive Technology ProMonitor 1000 ranks #167, rated 1.7/5, and costs $498, which makes this an easy call rather than a real tradeoff.
The JBL Stage 250B is the more accurate, deeper-bass option. Affordable current bookshelf speakers with a waveguide tweeter for smooth dispersion, magnetic grilles and solid build. Its measured preference score, a predictor of how neutral it sounds, is 4.06 against 3.20 for the Definitive Technology ProMonitor 1000. Its bass reaches about 64.5Hz before falling 3dB, against 95Hz for the Definitive Technology ProMonitor 1000. Watch for: Its objective score is good rather than class-leading, and the rear port needs some wall clearance.
The case for the Definitive Technology ProMonitor 1000: A small satellite speaker with low bass distortion and a footer that keeps the light cabinet planted. Watch for: CEA2034 spinorama shows severely reduced bass energy between 40-120Hz, a directivity mismatch between the tweeter and woofer, and a severe resonance/interference issue around 14kHz.
Buy the JBL Stage 250B. It is rated higher for sound quality than the Definitive Technology ProMonitor 1000 and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
