Short answer: the KEF R3 Meta for better sound quality, the HiVi Swans 3.1A Sehlin Sound Solutions mod for the lower price. The KEF R3 Meta ranks #10 of 130 bookshelf speakers at $2499.99. The HiVi Swans 3.1A Sehlin Sound Solutions mod ranks #61 at $364.99, $2135 cheaper.
What the KEF R3 Meta offers: Three-way design with an unconventional concentric layout: the 1” tweeter is recessed into the throat of the 5.25” midrange driver, deeper integration than a standard coaxial arrangement. A quasi sealed/ported bass alignment gives an extended low-end shelf tuned to match typical in-room gain, reaching about 50Hz for most content - deeper than recently-tested rivals like the Focal Aria 906, Polk R200, and an 8” Aperion design. Spinorama measurements show class-leading directivity and sound power, plus very linear on-axis response (at the recommended 10° toe-out) and early-reflections directivity, so it takes EQ exceptionally well. The vertical sweet spot extends to about ±20-30° off the reference axis with nearly identical tonality, unusually wide for a two- or three-way design. A clear upgrade over the earlier, non-Meta R3, eliminating the treble brightness the original had even when toed off-axis. Outperforms similarly-priced rivals (Revel M106, Wharfedale Linton, Philharmonic BMR V2, JBL HDI 1600) specifically on directivity and linearity in the reviewer’s measurements. At $2,200/pair, called the best value in its class with near-reference-level anechoic performance. Watch for: Pointed straight on-axis, there’s a 1-2dB bump around 9kHz that stays consistent across angles thanks to the constant-directivity waveguide - only toeing the speaker out about 10° tames it. Minimum impedance dips to about 3.2 ohms nominal (EPDR as low as 1.9 ohms), so it needs a 4-ohm-stable amplifier; a standard AVR likely won’t cut it. Distortion crosses the reviewer’s 3% threshold around 80Hz at 96dB output and shows added deviation again near 50Hz, indicating it runs out of headroom at higher volumes - a subwoofer is recommended for loud listening. Horizontal radiation narrows from about ±70° at low frequency to ±40° at high frequency. Below about 100Hz, compression testing shows fairly wide deviations at both 86dB and 96dB output, though the reviewer notes this is typical for speakers in this size and price class. Current R3 owners who are already happy with that speaker have little reason to upgrade.
What the HiVi Swans 3.1A Sehlin Sound Solutions mod offers: CEA2034 spinorama shows a mostly smooth on-axis response for a DIY three-way kit. Horizontal beamwidth of about ±70 degrees is wide and consistent. Distortion stays under control down to 40Hz at 96dB SPL/1m, a strong result for a 6.5” woofer in this class. Watch for: Some directivity error appears around 2.1kHz on-axis. Predicted in-room response needs about 1-2dB of correction to fit an ideal target curve. Vertical directivity is just okay, so listening height matters more than with a coincident design. Minimum impedance dips to 3.8 ohms with several peaks, a moderately demanding load. Requires DIY assembly (kit only), with additional Sehlin-mod parts and labor beyond the base kit price.
