HiVi Swans 3.1A Sehlin Sound Solutions mod vs Parts Express Samba MT

Last updated: September 30, 2026

Short answer: the HiVi Swans 3.1A Sehlin Sound Solutions mod. It ranks #63 of 134 bookshelf speakers by sound quality, rated 3.9/5, at $364.99. The Parts Express Samba MT ranks #85, rated 3.6/5, at $329.96, $35.03 cheaper, not enough of a saving to outweigh the sound-quality gap.

HiVi Swans 3.1A Sehlin Sound Solutions mod vs Parts Express Samba MT

Why pick the HiVi Swans 3.1A Sehlin Sound Solutions mod: CEA2034 spinorama shows a mostly smooth on-axis response for a DIY three-way kit. The catch: Some directivity error appears around 2.1kHz on-axis.

What the Parts Express Samba MT does well: A Dayton Audio designed two-way kit built around the RS180P-4 7-inch Reference paper woofer and the RST28F-4 fabric-dome tweeter, with CNC-cut MDF knock-down panels, the crossover parts and damping included. Watch for: The listening window spans 6.0dB between 300Hz and 5kHz in Erin’s Audio Corner’s measurements, less even than the best speakers here, and the preference score only reaches 6.27 with an ideal subwoofer.

Buy the HiVi Swans 3.1A Sehlin Sound Solutions mod. It is rated higher for sound quality, and saving $35.03 with the Parts Express Samba MT does not make up for the sound-quality gap.

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.

Pros: A Dayton Audio designed two-way kit built around the RS180P-4 7-inch Reference paper woofer and the RST28F-4 fabric-dome tweeter, with CNC-cut MDF knock-down panels, the crossover parts and damping included. Erin’s Audio Corner measured deep bass for a bookshelf, about 45Hz at -3dB and 34Hz at -10dB, a smooth predicted in-room response (0.69 smoothness) and wide horizontal dispersion averaging 60 degrees, for a preference score of 4.46. Measured bass extension of 45.4Hz (-3dB).

Cons: The listening window spans 6.0dB between 300Hz and 5kHz in Erin’s Audio Corner’s measurements, less even than the best speakers here, and the preference score only reaches 6.27 with an ideal subwoofer. It is a kit: you assemble the cabinet, solder the crossover and finish the raw MDF yourself, and each kit builds a single speaker.
