Rythmik FV25HP vs JTR Speakers Growler (2015)

What the Rythmik FV25HP offers: Independent CEA-2010 testing records 116.6 dB at 20 Hz and 126.2 dB through 40-80 Hz. The ported, front enclosure with 2x 15” (381mm) driver has the headroom for demanding film bass in a large room.

Ported output does not solve room modes, so careful placement and calibration remain essential.
