Precision Power HTW.654 – 6.5" 4-Ohm Weather-Resistant Horn-Loaded Motorcycle Speakers

What's Inside

Horn-loaded titanium tweeter. The HTW.654 uses a titanium tweeter mounted within a horn waveguide that focuses high-frequency output forward. The horn geometry concentrates the tweeter's radiated energy toward the rider's listening position rather than allowing it to disperse in all directions – increasing the intensity of what reaches the rider at highway speed and making the high frequencies more resistant to wind noise attenuation. Titanium provides the rigidity and low mass required for extended high-frequency response without the resonance of softer dome materials.

Polypropylene cone with Santoprene surround. A polypropylene woofer cone handles midrange and upper bass, co-moulded with a Santoprene surround. Santoprene is a thermoplastic rubber that maintains its elasticity across the temperature range and moisture exposure of open-air riding – resisting the UV, heat cycling, and road spray that cause foam surrounds to crack and rubber surrounds to harden over the service life of a motorcycle speaker installation.

High-output neodymium motor. A neodymium magnet motor delivers a high force factor within a compact form factor, keeping mounting depth within the constraints of standard fairing and lower fairing pod positions while supporting the HTW.654's 92 dB sensitivity.

ABS/fibreglass basket. The glass fibre reinforced ABS basket is dimensionally stable under motorcycle vibration loads, UV-resistant, and unaffected by corrosion in weathered open-air applications. No grilles are included; the fairing housing or aftermarket enclosure provides the finished appearance.

Integrated high-pass crossover. An internal crossover network manages frequency distribution between the woofer and horn-loaded tweeter, protecting the tweeter from low-frequency excursion and maintaining tonal balance across the operating range.

Sensitivity and Frequency Coverage

At 92 dB (1W/1m), the HTW.654 delivers strong output from standard amplifier power levels – appropriate for multi-speaker front-stage configurations where a single amplifier channel may drive both upper and lower fairing speakers. The 80 Hz – 20 kHz frequency response covers the full fairing speaker range in a system where low frequencies are managed by a subwoofer or high-pass filter. A high-pass crossover above 80 Hz at the amplifier is recommended to protect the woofer from excessive low-frequency excursion.

Why 4Ω

A 4Ω speaker is compatible with the full range of aftermarket motorcycle amplifiers, making it the practical default for amplified builds where the amplifier is not specifically rated for 2Ω operation. For riders running multi-channel systems where amplifier load stability across all channels matters – particularly when combining front and rear speakers on a shared amplifier – 4Ω loading provides a reliable operating point across the full system. Where 2Ω loading would allow more peak power extraction from a 2Ω-stable amplifier, the HTW.652 is the matching 2Ω variant.
