Understanding how the basic design differences influence the CDT Versabox subwoofers and how they compare with ordinary subwoofers will enable you and your installer to design a sound system both advancing your listening preferences and exceeding your listening expectations. The EF-Versabox subwoofers are designed for both audiophile & SPL user. The subwoofers are designed for the listeners who turn the volume up on some heavy rock and metal but still with a feel of smooth tight fast bass response. These engineering masterpieces simultaneously deal with the need to move large amounts of air necessary to overcome the 70+ db. of bass masking road noise in the moving automotive interior, while accurately responding to the delicate changes in the harmonic structure of the music.
