Default JBL or Velodyne

Hello
I am trying to decide between these two subwoofers, as their any opinions out there? JBL L8400 P - SPECIFICATIONS

General
Amplifier Power (RMS) - 600 Watts
Peak Dynamic Power - 1200 Watts;
the Peak Dynamic Power is measured by recording the highest peak-to-center voltage produced by the power amplifier with its limiters disabled, across the output of a resistive load equal to minimum impedance of the transducer, using a 50Hz sine wave burst, 3 cycles on, 17 cycles off.
Bass Driver - 12" (300mm) PolyPlas™cones with rubber surround, cast-aluminum chassis, HeatScape™ motor structure, Symmetrical Field Geometry™ (SFG™), oversized fiberglass voice coil, magnetic shorting ring
Frequency Response - (–3dB) 22Hz – Low-pass crossover frequency
Low-Pass Crossover Frequencies - 50Hz – 150Hz, continuously adjustable (150Hz when using speaker-level connection)
Inputs - Gold-plated 5-way binding-post speaker-level; left and right line-level, switchable to LFE
Outputs - Gold-plated, 5-way binding-post speaker-level
Enclosure Design - Sealed
Baffle - Low-diffraction, IsoPower™
Dimensions - (H x W x D) 16-1/2" (15-1/2" without feet) x 15-1/2" x 15-1/2"
Weight per Speaker - 58 lb
