Short answer: the JTR Speakers Growler (2015) if sound quality matters most, the SVS PB-4000 if price matters most. The JTR Speakers Growler (2015) ranks #13 of 110 subwoofers at $2995. The SVS PB-4000 ranks #62 at $2158.97, $836.03 cheaper.
What the JTR Speakers Growler (2015) offers: 12-inch ported driver reaches 130.2dB CEA-2010-A average, nearly matching the class leader for about $1,000 less. Watch for: Ported design room interaction, 45 kg size, and $2,995 cost.
What the SVS PB-4000 offers: Independent CEA-2010 testing records 115.3 dB at 20 Hz and 120.3 dB through 40-80 Hz. The ported, front enclosure with 13.5” (343mm) driver with ported design has the headroom for demanding film bass in a large room. Watch for: The 594.4H x 520.7W x 703.6D mm cabinet and 69.5 kg mass make this a serious placement and moving commitment. Ported output does not solve room modes, so careful placement and calibration remain essential.
