Kenwood XH Series KFC-XH170 High-Resolution Audio Certified 17 cm (6.5″) 2-Way Coaxial Flush Mount Speaker System

Description

The Kenwood KFC-XH170 represents the ultimate 2-way coaxial speaker system engineered for audiophiles seeking point-source acoustic accuracy without modified pillar pods. As part of Kenwood’s prestigious XH Series flagship line, this 17 cm flush-mount speaker combines a rigid glass-fiber woofer cone with a central silk-dome tweeter to deliver studio-quality clarity directly into factory door locations.

• Hi-Res Audio Certified Performance:

  Pushes frequency limits smoothly from 40 Hz low-end bass extensions up to 40,000 Hz, bringing out every micro-detail in high-bitrate digital music recordings.

• High-Rigidity Woven Glass-Fiber Cone:

  Features a lightweight yet extremely rigid glass-fiber woofer matrix that eliminates diaphragm flex, delivering fast mid-bass attack and uncolored vocal performance.

• Concentric Silk-Dome Tweeter Integration:

  Houses a high-grade soft silk dome tweeter right at the acoustic center of the woofer cone, ensuring perfect time alignment between high and mid frequencies.

• High-Efficiency 3-Ohm Impedance Design:

  Engineered with a low 3-ohm voice coil to optimize amplifier current draw, extracting maximum power output and headroom compared to standard 4-ohm speakers.

• Pro-Grade Die-Cast Aluminum Frame & Motor Assembly:

  Supported by a heavy-duty cast basket structure equipped with direct-mounted crossover filter networks and gold-plated terminals for lossless signal transfer.

• Seamless OEM Flush-Mount Capability:

  Designed with factory-fit depth dimensions and protective grilles, providing reference-level sound output while retaining your car cabin’s original aesthetic.

HIGH-RESOLUTION AUDIO (HI-RES) PERFORMANCE

• Official Hi-Res Audio Certified:

  Passes strict acoustic standards to reproduce uncompressed 24-bit digital formats (FLAC, WAV, DSD) with lifelike realism.

• Extended 40,000 Hz (40 kHz) Frequency Ceiling:

  While conventional speakers roll off at 20 kHz, the KFC-XH170 reaches 40 kHz, ensuring upper harmonics and vocal ambient air are reproduced with liquid smoothness.

• Clean 40 Hz Low-End Response:

  Delivers deep, articulate mid-bass impact down to 40 Hz, giving drums and basslines natural presence without speaker strain.

• Linear Point-Source Phase Alignment:

  By aligning the tweeter and woofer on a single axis, sound waves reach your ears simultaneously, resulting in precise soundstage focus and zero phase smearing.

COMPREHENSIVE TECHNICAL BREAKDOWN & WORKING MECHANISM

1. WOOFER / MID-BASS DRIVER (17 cm / 6.5″)

• Glass-Fiber Woven Diaphragm: High-stiffness cone material designed for rapid piston motion and tight, articulate mid-bass output.

• Durable Rubber Surround: Controls edge resonances while enabling long linear excursion under high power loads.

• Die-Cast Aluminum Basket: A rigid frame that dampens motor resonances and acts as a heat sink for the magnet assembly.

2. COAXIAL TWEETER ASSEMBLY (Silk Dome)

• Pure Silk Fabric Dome: Renders smooth high frequencies up to 40 kHz without harshness or listener fatigue.

• Integrated Crossover Network: High-grade inline crossover components mounted directly on the frame to route high frequencies safely to the tweeter.

3. MOTOR & IMPEDANCE SPECIFICATION

• 3-Ohm Low-Impedance Voice Coil: Safely pulls extra wattage from car amplifiers, maximizing total acoustic output and dynamic headroom.

TECHNICAL SPECIFICATION INDEX:

WHY COAXIAL SPEAKERS ARE SPECIFICALLY DESIGNED FOR REAR DOORS

1. No Dedicated Tweeter Slots in Rear Panels:

Most car manufacturers do not provide dedicated tweeter housing, sail panels, or A-pillar mounts in the rear doors. Installing a component system would require drilling holes or custom body modifications. Coaxial speakers solve this by integrating the silk dome tweeter directly over the center of the woofer cone, fitting 100% into factory door cutouts without modifying the vehicle interior.

2. Built-In Tweeter for Instant Point-Source Sound:

Because the tweeter and woofer share a single axis (point-source architecture), all high, mid, and low frequencies originate from one spot. This guarantees clean, full-range frequency response for rear passengers without needing extra crossover boxes or separate wiring runs inside the rear door panels.

3. Ideal “Rear Fill” Acoustic Staging:

In high-end car audio design, the front soundstage (handled by component speakers on dashboard/A-pillars) creates primary vocal and instrument imaging. Rear coaxial speakers provide essential rear fill—filling the back cabin with dynamic ambience, mid-bass weight, and subtle treble details so the cabin feels like a full 3D soundstage rather than flat front audio.

4. Hassle-Free Plug-and-Play Installation:

Upgrading rear doors with coaxial speakers requires zero custom fabrication. They connect directly to existing factory speaker harnesses, saving installation time while maintaining clean OEM finish and full dynamic performance.
