Glass Fiber Woofer Cone for Controlled Midbass and Natural Vocals
At the heart of the Kenwood Excelon Reference XR-1701 is a lightweight, rigid 6.5-inch glass fiber woofer cone.
Speaker cone materials must balance strength and responsiveness. A cone that flexes excessively can introduce unwanted distortion, while excessive moving mass can reduce responsiveness.
Kenwood’s glass fiber construction is designed to provide the structural rigidity necessary for accurate sound reproduction without unnecessary weight.
This helps the XR-1701 deliver:
- Controlled midbass response
- Natural vocal reproduction
- Detailed lower-midrange performance
- Responsive reproduction of musical transients
- Consistent performance across a broad listening range
Circle Rib Woofer Cap for Improved Stability
Kenwood incorporates a circular rib structure into the woofer cap to help reinforce the cone assembly.
This design supports controlled movement during demanding musical passages and helps maintain structural stability.
For listeners who enjoy complex music with rapid bass transitions, acoustic instruments, or layered vocals, consistent woofer behavior is an important part of maintaining sound quality.
Asymmetrical Surround Roll for Focused Bass
The XR-1701 also features an asymmetrical surround roll design.
The surround helps control cone movement while allowing the woofer to move through its intended excursion range.
Kenwood’s asymmetrical geometry is designed to support more focused bass reproduction and controlled movement.
Combined with a properly sealed installation, the woofer can provide satisfying midbass without the loose, muddy character often associated with worn factory speakers.
Although the XR-1701 offers strong potential for midbass performance, drivers seeking substantial deep bass should consider adding a dedicated subwoofer.
Oversized 30mm Titanium Dome Tweeter for Exceptional Clarity
One of the defining features of the Kenwood XR-1701 is its 1-3/16-inch (30mm) titanium hard-dome tweeter.
This larger-format tweeter is engineered for detailed high-frequency reproduction, helping bring vocals, cymbals, strings, and other musical elements into focus.
Its compound-curvature diaphragm contributes to the extended high-frequency performance expected from a Hi-Res Audio Certified speaker.
Titanium’s combination of low mass and rigidity makes it well suited to reproducing rapid high-frequency changes.
The result is a tweeter designed to deliver precise upper-frequency detail without requiring a separate mounting location.
Unlike the XR-1701P component system, the XR-1701’s tweeter is integrated into the coaxial speaker assembly.
This makes installation more straightforward while retaining the advanced materials and premium engineering associated with Kenwood Excelon Reference speakers.
100W RMS Power Handling for Serious Aftermarket Audio Systems
The Kenwood XR-1701 is rated at 100 watts RMS and 300 watts peak power.
For amplifier selection, the 100W RMS rating is the more meaningful specification.
Continuous power handling helps determine how much sustained amplifier output the speaker is designed to accommodate under appropriate operating conditions.
The XR-1701’s 3-ohm impedance also deserves attention.
Compared with a conventional 4-ohm speaker, a 3-ohm speaker can draw more current at the same output voltage. This may allow compatible amplifiers to deliver additional power, but amplifier stability must be verified before installation.
A properly matched aftermarket amplifier can help the XR-1701 deliver cleaner dynamic peaks and greater listening headroom.
Our car amplifier setup guide explains how RMS ratings, impedance, gain adjustment, and amplifier selection affect performance and speaker reliability.
For enthusiasts building a premium audio system, matching the XR-1701 with clean amplification is a worthwhile investment.
Premium Coaxial Design for Convenient Factory Speaker Replacement
One of the greatest advantages of the Kenwood XR-1701 is its ability to deliver high-end speaker technology in a practical coaxial configuration.
Component systems require separate tweeter mounting positions and additional wiring considerations. The XR-1701 simplifies the process by combining its drivers into one speaker assembly.
This makes it especially useful for factory speaker replacements where maintaining a clean interior appearance is a priority.
Potential installation locations include:
- Compatible front door speaker openings
- Rear door speaker locations
- Rear side-panel installations
- Custom speaker enclosures
- Factory locations designed for 6.5-inch speakers
The XR-1701 includes multi-use mounting brackets intended to accommodate a variety of vehicle configurations.
However, nominal speaker size alone does not guarantee fitment.
Before purchasing, verify the factory cutout diameter, mounting depth, bolt pattern, available clearance, and wiring connections.
Kenwood specifies a 5.5-inch cutout diameter and 2-5/16-inch mounting depth for this model.
Proper speaker mounting is essential for achieving the best possible midbass response and minimizing unwanted door-panel vibrations.

Kenwood XR-1701 vs. XR-1701P: What’s the Difference?
Although the model names are nearly identical, the Kenwood XR-1701 and XR-1701P are designed for different installation preferences.
The XR-1701 is a coaxial speaker system that integrates the tweeter into the woofer assembly.
The XR-1701P is a component speaker system with separately mounted tweeters and external bi-ampable crossover networks.
Both models share several important characteristics, including glass fiber woofers, 30mm titanium dome tweeters, 100W RMS power handling, and 3-ohm impedance.
Choose the XR-1701 if you want premium sound with a simpler installation and fewer separate components.
Choose the XR-1701P if you’re building a more elaborate front soundstage and want the flexibility to position tweeters independently.
For many daily drivers, the XR-1701 provides an excellent compromise between premium audio performance and practical installation.
