Rythmik FV15HP vs JTR Speakers Growler (2015)

Short answer: the Rythmik FV15HP, if you are buying new. The JTR Speakers Growler (2015) ranks higher than it (#13 vs #55 of 143 subwoofers, 4.5/5 vs 4.2/5) but is discontinued, so only consider it used; the Rythmik FV15HP is still sold new at $2,127.

The case for the Rythmik FV15HP: A 15 inch ported subwoofer with output matching pricier rivals, plus balanced and RCA inputs for flexible setups. Watch for: Premium price ($2127), ported design room gain dependency, and mid-to-large 114.6 lbs (52 kg) footprint.

What the JTR Speakers Growler (2015) does well: A 12 inch ported subwoofer with output close to far bigger flagships, a strong used pick now that it is discontinued. The tradeoff: Ported design room interaction, 99.2 lbs (45 kg) size, and $2995 cost.

Buy the Rythmik FV15HP, since the JTR Speakers Growler (2015) is discontinued and only worth hunting down used.
