Short answer: the SVS SB-3000 R|Evolution. Both are rated 4.1/5 for sound quality (#23 and #24 of 212 subwoofers), and the SVS SB-3000 R|Evolution costs $1,299 against $1,599 for the Rythmik E15, so with nothing between them on sound quality, price settles it.
The case for the Rythmik E15: A compact sealed 15” Direct Servo subwoofer, narrower and shallower than Rythmik’s F15, driven by the 600W H600 amplifier. The catch: No independent measurements yet, so its output can’t be compared directly with ranked subwoofers; the rating is estimated from the measured sealed Rythmik F12 and ported Rythmik FV15HP (119.3 and 122.0dB in the 40 to 80Hz CEA-2010 bands).
Why pick the SVS SB-3000 R|Evolution: Compact sealed 13-inch high-excursion driver backed by a 1,200W RMS (4,000W peak) Sledge STA-1200D2 MOSFET amplifier with a 295MHz DSP engine. The catch: A sealed enclosure trades raw low-end output below 25Hz compared to ported models like the SVS PB-3000 R|Evolution, requiring careful room boundary placement or dual subwoofers in large open spaces.
Buy the SVS SB-3000 R|Evolution. Both are rated the same for sound quality, and it costs $300 less than the Rythmik E15.
About the ratings: neither speaker has been measured yet, so both ratings are estimated from measured siblings and predecessors (likely ranges: Rythmik E15 3.7 to 4.2; SVS SB-3000 R|Evolution 3.9 to 4.3). Treat this verdict as provisional.
