Shure RPW186 – KSM9HS Wireless Replacement Cartridge, Black

Product Overview

The Shure RPW186 is a genuine OEM replacement cartridge and housing assembly for Shure wireless handheld transmitters equipped with the KSM9HS condenser capsule in black. The KSM9HS uses hypercardioid and subcardioid polar patterns rather than the cardioid/supercardioid patterns of the standard KSM9, making it the preferred choice for applications where maximum rear rejection and tight pickup control are specified. Compatible with Shure wireless systems that accept the KSM9HS interchangeable capsule, including select ULXD, QLXD, and Axient Digital handheld transmitter models. Limit of one per order applies.

Product Description

The KSM9HS is Shure’s hypercardioid condenser wireless capsule, featuring dual-diaphragm construction with gold-layered Mylar diaphragms and switchable hypercardioid/subcardioid polar patterns. The hypercardioid pattern offers tighter forward pickup and greater rear rejection than a standard supercardioid, making the KSM9HS specifically suited to high-feedback-risk environments such as monitor-heavy stage setups and acoustically challenging commercial spaces. When an RPW186 capsule is damaged, this replacement element restores the KSM9HS’s tight polar response and premium condenser vocal performance to the transmitter body. For the standard KSM9 cardioid/supercardioid variant, see the Shure RPW184.

Key Features

• KSM9HS Hypercardioid/Subcardioid Polar Patterns — Tighter polar response than the standard KSM9, delivering superior rear rejection and narrow forward pickup for demanding feedback-control environments.
• Premium Condenser Performance — Dual-diaphragm condenser construction with gold-layered Mylar diaphragms provides extended frequency response and low self-noise for high-fidelity wireless vocal reproduction.
• Black Finish — Designed for black-bodied Shure wireless transmitters, maintaining consistent system appearance in commercial AV installations.
• OEM Replacement Assembly — Genuine Shure factory replacement element ensures acoustic performance identical to the original KSM9HS specification.
• Limit One Per Order — Order restriction applies; contact Creation Networks for volume purchasing requirements.

Typical Applications

• Broadcast studios where tight pickup pattern control is required for vocal isolation
• House of worship with active monitor fills where maximum feedback rejection is necessary
• Government spaces and auditoriums with challenging acoustic environments
• Boardrooms and conference rooms where high-ambient-noise conditions warrant a tighter polar pattern
• All-hands rooms and large commercial meeting spaces with installed premium wireless

Frequently Asked Questions

What is the difference between the KSM9HS (RPW186) and the standard KSM9 (RPW184)?
The KSM9 (RPW184) uses switchable cardioid and supercardioid polar patterns. The KSM9HS (RPW186) uses hypercardioid and subcardioid patterns. The hypercardioid pattern has a narrower acceptance angle and greater rear rejection than supercardioid, making the KSM9HS better suited to environments with high ambient sound levels or active monitor systems. Always use the replacement element that matches the capsule originally installed in the transmitter.

Which wireless systems accept the RPW186?
The RPW186 is compatible with Shure handheld wireless transmitters that accept the KSM9HS capsule, including select ULXD, QLXD, and Axient Digital models. Confirm your specific transmitter model against Shure’s published compatibility documentation before ordering.

Is the RPW186 a complete assembly?
Yes. The RPW186 ships as a complete capsule and housing assembly. It includes the KSM9HS element and housing for straightforward field replacement.

Is this a genuine Shure OEM part?
Yes. The RPW186 is a genuine Shure factory replacement capsule, manufactured to the same specification as the original KSM9HS supplied in new wireless transmitters.
