Pros: 1” aluminum dome tweeter with a distinctive partial-lens waveguide design paired with a 6.5” third-generation aramid fiber cone woofer, in a robustly built cabinet for the price. Shallow bass rolloff (F3 76Hz, F10 40Hz) allows placement close to a wall without excessive boominess, useful for smaller living rooms. Solid measured performance for the price: on-axis linearity within about 2.5dB, impedance dipping only to about 4.4 ohms (easily AVR-driven), and roughly 20-26dB of usable dynamic range. A clear improvement over its sibling ELAC DB62, which has a sibilance issue tied to the crossover that can’t be fixed with EQ. Wide horizontal radiation of about ±60°, giving a spacious soundstage. Distortion looks good at a moderate 86dB and still reasonable at 96dB. Takes well to EQ correction - the reviewer provides a specific filter set (a low-shelf boost at 650Hz plus peaking cuts/boosts at 550Hz, 660Hz, and 3kHz) that meaningfully smooths out its known deviations. Measured bass extension of 76Hz (-3dB), with a measured sensitivity of 86.2dB.
Cons: A dip in the lower midrange (300-600Hz, about 1.5dB) reduces vocal warmth and can make voices sound slightly hollow. A high-Q resonance around 650-750Hz shows up clearly in measurements, though the reviewer couldn’t reliably hear it in his own A/B testing. A dip around 2-3kHz (roughly 1-2dB) slightly reduces speech intelligibility and attack in the upper midrange. Directivity droops above about 2kHz as the midwoofer narrows toward its beaming frequency while the tweeter’s pattern behaves differently - an inherent trade-off of physically separated drivers that can’t be fully corrected without introducing other issues. Multitone distortion crosses the reviewer’s 3% threshold in the 200Hz-1kHz range, and adding a subwoofer at an 80Hz crossover only modestly reduces it. Toeing the speaker away from the listener loses noticeable top-end air and cymbal energy, giving a softer upper register. Practical loudness ceiling is around 90dB at typical listening distance before midrange distortion and bass attack begin to degrade. Still needs a subwoofer for extension below about 40Hz.

HiVi Swans 3.1A Sehlin Sound Solutions mod: $364.99 per pair for the kit (assembly required) Amazon eBay
Pros: 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. Measured bass extension of 60Hz (-3dB), with a measured sensitivity of 86.5dB.
Cons: 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.
