About the Alpine HDZ-65CS Alpine Status high-resolution audio system Alpine designed its Status System components for high-resolution audio playback. Their Status Series digital receiver, amp, speakers, and subs were designed to work together and play your 192kHz/24bit digital music streaming files with high-quality, studio-level purity and sonic fidelity. Ready for high-resolution Alpine crafted their HDZ-65CS 6-1/2" 2-way component speaker system for listeners in search of excellent audio quality in the car. Using many of the same design and material elements as their flagship F#1 Status speakers, this speaker system optimizes the woofer, tweeter, and crossover for near-perfect sound from premium sources, like high-resolution audio files. Optimized for Alpine These Status Series speakers make a great addition to any high-powered system, thanks to power-handling up to 100 watts RMS, but you can unlock their full potential by pairing them with Status System components, which Alpine designed with high-resolution audio in mind. Alpine uses a carbon composite cone for consistency across the speaker's ultra-wide frequency range, plus a special double gathered-edge surround, which helps minimize distortion and promote accuracy. Alpine prioritizes tweeter fit If you're upgrading a factory 3-way component system, Alpine optimizes fit to minimize the need for custom work. Their slim-fit 1" tweeter makes it easier to utilize the factory tweeter locations of more vehicles.

Please enter your vehicle information to confirm fit. Cone Material: The same carbon composite cone material is used for both the woofers and tweeters, aiding the smooth transition between the drivers. Phase Plug: The woofers and tweeters use an aluminum phase plug in the center of the cone to help produce a smooth, flat off-axis frequency response by preventing the high frequency sound waves from one side of the cone from interfering with sound waves from the other side of the cone. Tweeters: The tweeters are designed to be flush mounted, with the mounting surface sandwiched between the tweeter flange and the threaded mounting ring. Tweeter Dimensions: Flush Mount Mounting Height 0.48" Mounting Depth 0.57" Cutout Diameter 2" Frame Diameter 2.275" Crossover: The passive crossovers allow some system flexibility; the tweeter output level and crossover slope are adjustable. Tweeter Output Level: three jumper positions; choose -3 dB, 0 dB (flat), or +3 dB Crossover Slope: two jumper positions; choose 12 dB/octave or 6 dB/octave Wire Connections: inputs and outputs are screw terminals; accept bare wire or spade connectors up to 0.315" wide (no wire is included with the speakers) Crossover Dimensions: Width: 5.32" Height: 1.625" Depth: 3.94" (plus wire)
