Freshen up your sound. Looking to add a little oomph to your system? Swap out your old speakers for Hertz’s Dieci Series 6-1/2″ component speaker system and take your sound to a new level. An external crossover channels the lower frequencies to a specialized V-cone woofer enhanced for off-axis listening, and directs high frequencies to a separate PEI dome tweeter.
Improved linearity and reliable performance give you impressive dynamic range for new enjoyment of old favorites. Hertz believes that a good speaker should bring out the emotional power of the music you love. That’s a high bar, but with their commitment to using premium components and boundary-pushing design, they’re more than up to challenge.
