Funk Audio Classic 18.0 vs JL Audio Fathom f212v2

Short answer: the Funk Audio Classic 18.0. It ranks #17 of 143 subwoofers by sound quality, rated 4.4/5, at $9,875; the JL Audio Fathom f212v2 ranks #41, rated 4.3/5, and costs $10,000, which makes this an easy call rather than a real tradeoff.

What the Funk Audio Classic 18.0 does well: Independent CEA-2010 testing records 106.5 dB at 20 Hz and 127.3 dB through 40-80 Hz. 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.

Why pick the JL Audio Fathom f212v2: JL Audio’s dual-driver Fathom: two 12” W7 drivers and a 3600W amplifier in a tall sealed cabinet, rated 20 to 97Hz (±1.5dB) and 15Hz at -10dB anechoic, with automatic room optimization. The catch: No independent measurements yet, so its output can’t be compared directly with ranked subwoofers; the rating is estimated from the measured JL Audio Fathom f113 (118.9dB in the 40 to 80Hz CEA-2010 bands): two 12” drivers with twice the cone area and 3600W should add several dB, putting it among the louder sealed subs.

Buy the Funk Audio Classic 18.0. It is rated higher for sound quality than the JL Audio Fathom f212v2 and costs less, so only choose the other one for a particular feature it does better.

Worth knowing: the JL Audio Fathom f212v2 has not been measured yet. Its rating is estimated from related models, with a likely range of 3.9 to 4.5, so treat this verdict as provisional.

Funk Audio Classic 18.0: $9,875 Funk Audio eBay

Same family: the Funk Audio Classic 21.0L (larger subwoofer, ranked lower, rated 4.2/5).

Pros: Independent CEA-2010 testing records 106.5 dB at 20 Hz and 127.3 dB through 40-80 Hz. The sealed enclosure with 18” (457mm) driver delivers formidable upper-bass output for movie effects and music.

Cons: 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 571.5H x 558.8W x 520.7D mm cabinet and 52.2 kg mass still require deliberate placement and calibration.

Notes: Data-bass labeled this sub as ‘FW18.0’, but original name is 18.0
