Genelec HTS4B vs Magico Audio ASUB

Last updated: September 8, 2026

Short answer: the Magico Audio ASUB on measured sound quality, the Genelec HTS4B on price. The Magico Audio ASUB ranks #92 of 97 subwoofers at $6500. The Genelec HTS4B ranks #93 at $2995, $3505 cheaper.

What the Genelec HTS4B offers: Independent CEA-2010 testing records 97.9 dB at 20 Hz and 110.3 dB through 40-80 Hz. The passive radiator enclosure with 12” (305mm) driver delivers substantial upper-bass output for movie effects and music. Watch for: Deep-bass output is more limited than the strong 40-80 Hz result suggests, so it is not the right choice when the lowest movie effects are the priority. The 517.4H x 482.6W x 465.1D mm cabinet and 37.0 kg mass still require deliberate placement and calibration.

What the Magico Audio ASUB offers: Independent CEA-2010 testing records 94.3 dB at 20 Hz and 111.1 dB through 40-80 Hz. The sealed enclosure with 10” (254mm) driver delivers substantial upper-bass output for movie effects and music. Watch for: Deep-bass output is more limited than the strong 40-80 Hz result suggests, so it is not the right choice when the lowest movie effects are the priority. The 457.2H x 368.3W x 447.0D mm cabinet and 49.0 kg mass still require deliberate placement and calibration.

Buy the Genelec HTS4B if the price matters more than sound quality. Buy the Magico Audio ASUB if sound quality matters more than the price.

If sound quality matters at all to you, skip both of these and look higher up the 97 subwoofers instead.
