Shure RPW174 – KSM8 Dualdyne Wireless Capsule for Black Transmitters

Product Overview

The Shure RPW174 is a black KSM8 Dualdyne wireless capsule compatible with Shure interchangeable handheld transmitters, enabling wireless deployment of the KSM8’s dual-diaphragm cardioid dynamic performance. Designed for commercial AV integrators maintaining premium Shure wireless microphone systems, the RPW174 is the correct capsule for black-finished Shure wireless transmitters, and delivers the same KSM8 Dualdyne acoustic performance as the nickel RPW170. Compatible with select Shure handheld transmitters across the ULXD, QLXD, SLXD, and Axient Digital platforms.

Product Description

The KSM8 Dualdyne design uses two diaphragms working in concert within a dynamic transducer, providing extended frequency response that approaches condenser microphone performance while retaining the SPL-handling durability of a dynamic. This makes the RPW174 particularly well suited to commercial AV environments, houses of worship, and live reinforcement where both vocal detail and reliable dynamic behavior under demanding conditions are required. The black finish is designed for black-body Shure wireless transmitters, maintaining system appearance consistency. For the same capsule in brushed nickel, see the Shure RPW170.

Key Features

• Dualdyne Technology — Dual-diaphragm dynamic transducer design extends the frequency response of a dynamic capsule, providing condenser-like vocal detail with dynamic-class SPL handling and durability.
• Cardioid Polar Pattern — Natural cardioid directionality provides off-axis rejection suited to vocal reinforcement in commercial meeting spaces, auditoriums, and houses of worship.
• Black Finish — Designed specifically for black-finished Shure wireless transmitters to maintain system aesthetic consistency.
• Wireless System Compatibility — Compatible with select Shure handheld transmitters in the ULXD, QLXD, SLXD, and Axient Digital families that accept interchangeable capsules.
• Dynamic Transducer Durability — Dynamic construction handles high-SPL environments without the phantom power requirements or humidity sensitivity of condenser capsules.

Typical Applications

• House of worship wireless vocal reinforcement requiring extended dynamic range
• Boardroom and conference room wireless microphone systems
• All-hands rooms and multi-purpose commercial meeting spaces
• Live sound reinforcement in auditoriums and performance venues
• Commercial installation where black-finish wireless transmitters are deployed

Frequently Asked Questions

What is Shure’s Dualdyne technology?
Dualdyne is Shure’s dual-diaphragm design for dynamic microphone capsules. Two diaphragms work in tandem within a single dynamic transducer housing, extending the frequency response and improving vocal detail beyond what a standard single-diaphragm dynamic capsule achieves.

Why does the RPW174 come in black specifically?
Shure offers the KSM8 wireless capsule in two finishes to match the body color of compatible transmitters: black (RPW174) and brushed nickel (RPW170). Both versions deliver identical acoustic performance. Use the RPW174 with black-bodied Shure wireless transmitters.

Which Shure wireless systems are compatible?
The RPW174 is compatible with Shure handheld transmitters in the ULXD, QLXD, SLXD, and Axient Digital families that accept interchangeable capsules. Confirm compatibility with your specific transmitter model against Shure’s published documentation before ordering.

Is the RPW174 appropriate for installed commercial AV systems?
Yes. The RPW174 is well suited to installed commercial AV deployments, particularly in environments where a dynamic capsule’s durability, humidity tolerance, and high-SPL handling are preferred over condenser alternatives.
