KEF Q Concerto Meta vs HiVi Swans 3.1A Sehlin Sound Solutions mod

What the KEF Q Concerto Meta offers: Really good in-room neutrality with consistent horizontal directivity from seat to seat. Directivity holds remarkably steady from lower treble into upper treble, where many similarly-priced speakers narrow sharply as frequency rises - one of the reviewer’s top 10 picks under $1,500. Watch for: Radiation pattern measures about ±50°, narrower than the reviewer’s preferred ±60° for a stronger sense of envelopment. Needs to be pointed closer to on-axis rather than heavily toed out - combined with its rolled-off, shelved-down top end, too much toe-out makes it sound noticeably dark.

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.
