#143 Sonus Faber Gravis VI: $7,978.80 eBay
Pros: A luxury sealed subwoofer with two 12 inch drivers in a finely finished cabinet for music systems. Independent CEA-2010 testing records 86.0 dB at 20 Hz and 106.3 dB (avg of 3/4 bands) through 40-80 Hz. The sealed enclosure with 2x 12” (305mm) driver delivers substantial upper-bass output for movie effects and music.
Cons: 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 614.7H x 447.0W x 584.2D mm cabinet and 52.0 kg mass still require deliberate placement and calibration.
Is the Sonus Faber Gravis VI right for you?
Skip it if
- you need to move it often (52 kg each).
- you want the best value: the higher-rated JTR Speakers Orbit Shifter PRO costs about $3,480 less.
