RSL (Rogersound Labs) Speedwoofer 12S vs JTR Speakers Growler (2015)

Short answer: the RSL (Rogersound Labs) Speedwoofer 12S, if you are buying new. The JTR Speakers Growler (2015) ranks higher than it (#13 vs #131 of 143 subwoofers, 4.5/5 vs 3.7/5) but is discontinued, so only consider it used; the RSL (Rogersound Labs) Speedwoofer 12S is still sold new at $884.96.

Why pick the RSL (Rogersound Labs) Speedwoofer 12S: An affordable rear ported 12 inch subwoofer with strong deep bass output for movies. The catch: The 565.1H x 479.4W x 562.0D mm cabinet and 82 lbs (37.2 kg) mass make this a serious placement and moving commitment.

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

Buy the RSL (Rogersound Labs) Speedwoofer 12S, since the JTR Speakers Growler (2015) is discontinued and only worth hunting down used.
