Short answer: the MoFi SourcePoint 8. It ranks #17 of 223 bookshelf speakers by sound quality (rated 4.5/5) at $2,594 and is still sold new; the JBL HDI-1600 ranks #53 (rated 4.2/5) and is discontinued, so it is only an option used.
What the MoFi SourcePoint 8 does well: A bookshelf speaker with an 8 inch concentric driver, neutral sound, excellent imaging, and wide dispersion that forgives placement. The tradeoff: Like other coincident designs, produces diffraction dips around 4kHz and 7kHz when pointed directly on-axis; needs about 10-15° of toe-out to smooth those out.
What the JBL HDI-1600 does well: A bookshelf speaker with very flat mids and treble, smooth dispersion, and a slight bass lift that sounds full and natural. The tradeoff: A dip appears above 10kHz on-axis.
Buy the MoFi SourcePoint 8. It is rated higher for sound quality, and the JBL HDI-1600 is discontinued, so it is only available used.

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.
