Whise® understands the extreme demands accurate music reproduction places on loudspeakers. By using the most advanced computer design techniques, Whise® research and development engineers have produced the world's first Profunderreference sub bass loudspeaker series that are designed on the new and patented Parametric Acoustic Modelling (PAM) technology.

The Profunder 624 is a premium quality, high performance reference sub bass loudspeaker designed with a 24HZ corner frequency rated @ 600 watts rms. The speaker reproduces high SPL in excess of 121db from  24Hz -200Hz. @  ± 2db. The speaker is TMH Qualified being fully compliant with TMH Corp's stringent performance standards.
The Profunder 624 effortlessly reproduces the dynamic transients and finest bass nuances for professional studio and domestic home theater installations. You can be confident that the performance of the Profunder 624 will exceed specifications demanded but rarely given by other manufacturers.

The Profunder 624 is protected by “Guardian” as standard. Guardian is a unique design that allows no interference with the signal path except under gross fault conditions, and automatically resets when the fault clears. For optimum performance the Profunder 624 requires an appropriate crossover. The Whise® FFX 25 Active crossover meets these precise requirements.
