Short answer: the O.S. Acoustics DBS8. It ranks #35 of 119 powered bookshelf speakers by sound quality (rated 4.4/5) at $5,600 and is still sold new; the Dynaudio Core 47 ranks #75 (rated 4.1/5) and is discontinued, so it is only an option used.
The case for the Dynaudio Core 47: A professional three-way studio monitor with useful bass and flexible installation controls, with analog and digital inputs. The catch: The measured 3.1dB response span from 300Hz to 5kHz and listening-window unevenness keep it below the leading accuracy choices.
The O.S. Acoustics DBS8 is the more accurate option. Sealed active studio monitors with balanced sound and DSP adjustment, a good fit for a system with a subwoofer. Its measured preference score, a predictor of how neutral it sounds, is 5.88 against 4.99 for the Dynaudio Core 47. Watch for: The measured -3dB point is 48.5Hz, not especially deep for a large monitor.
Buy the O.S. Acoustics DBS8. It is rated higher for sound quality, and the Dynaudio Core 47 is discontinued, so it is only available used.
