What the JTR Speakers Captivator 1400 offers: Independent CEA-2010 testing records 116.1 dB at 20 Hz and 125.2 dB through 40-80 Hz. The ported, front enclosure with 18” (457mm) driver has the headroom for demanding film bass in a large room. Watch for: The 508.0H x 762.0W x 571.5D mm cabinet and 64.4 kg mass make this a serious placement and moving commitment. Ported output does not solve room modes, so careful placement and calibration remain essential.

The ported, front enclosure with 13.5” (343mm) driver with ported design has the headroom for demanding film bass in a large room. Watch for: The 594.4H x 520.7W x 703.6D mm cabinet and 69.5 kg mass make this a serious placement and moving commitment. Ported output does not solve room modes, so careful placement and calibration remain essential.
