This sound horn equalized the sound wave speed coming from the tweeter and smoothes the dispersion pattern for a smooth response. Below the horn, there are three 6.5" fiber composite woofers, whose light and powerfull design give deep bass response. There is also a front firing flared port below the three woofers for bass reflex. There is a removable grill cover over the horn for an even cripser sound, while the lower grill cover is fixed to protect the woofers from damage. The MDF cabinet has internal bracing to prevent unwanted vibrations, and is covered in a stylish black furniture-grade wood veneer making these speakers as good looking as they sound. There is a high-definition, precision-voiced crossover for tighter tolerance and higher accuracy and the speaker is magnetically shielded to avoid TV interference. The Klipsch VF-36 is available at Best Buy, and is sold individually for $499.
