Harbinger V2218S vs JTR Speakers Growler (2015)

Last updated: September 16, 2026

Short answer: the JTR Speakers Growler (2015). It ranks #13 of 110 subwoofers by sound quality at $2995; the Harbinger V2218S ranks #15 and costs $3495, so there is little reason to consider the other one.

Harbinger V2218S vs JTR Speakers Growler (2015)

What the Harbinger V2218S offers: Independent CEA-2010 testing records 81.7 dB at 20 Hz and 128.9 dB through 40-80 Hz. The ported, front enclosure with 18” (457mm) driver delivers formidable 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 825.5H x 673.1W x 754.4D mm cabinet and 40.8 kg mass still require deliberate placement and calibration.

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.

Buy the JTR Speakers Growler (2015). It ranks higher for sound quality than the Harbinger V2218S and costs less, which settles it without a real tradeoff to make.
