Yamaha SPW-1 Wheel Kit — Purpose-Built Transport Solution for DXS Subwoofers

The Yamaha SPW-1 Wheel Kit is the official caster upgrade for Yamaha DXS-Series powered subwoofers, converting a stationary low-frequency cabinet into a mobile, rig-ready unit. Each kit ships with four pre-engineered casters that mount to the subwoofer's factory-prepared attachment points, eliminating drilling or aftermarket fabrication. Designed in-house by Yamaha, the kit preserves the original enclosure geometry while adding smooth-rolling mobility for touring crews, mobile DJs, and rental houses. Audio professionals who need to move heavy DXS subwoofers between venues without lifting will appreciate this specific model.

What Sets the SPW-1 Apart from Generic Caster Sets

Unlike universal wheel boards that require drilling and add bulk, this model bolts directly to the cabinet using Yamaha's pre-threaded mounting points. Radial ball bearings inside each caster deliver quiet, low-friction rolling that won't rattle during quiet program material or broadcast work. Shipped with dedicated protection sheets and a hex key, the installation requires no extra hardware runs.

Subwoofer Compatibility — Direct Fit Across the DXS Family

Compatibility is the primary asset of this kit: one caster set covers nearly the entire current DXS lineup, simplifying fleet management for rental and touring operations.

• Compatible Models: DXS18, DXS15mkII, DXS15, DXS12mkII, DXS12, DXS18XLF(-D), DXS15XLF(-D) — full current DXS subwoofer range
• Mounting Style: Direct bolt-on to factory-prepared points — no drilling, no cabinet modification
• Equipping one subwoofer with this set is a simple task that requires no cabinet modifications.

Caster Specifications — Quiet Rolling Under Load

The casters are engineered for the weight class of DXS subwoofers, so bearing quality directly affects how the cabinet feels during transport.

• Wheel Diameter: 75 mm (3") — clears standard stage edges and cable runs
• Caster Dimensions: 100 x 95 x 62 mm — compact footprint keeps the cabinet close to the ground
• Radial ball bearings provide smooth and rattle-free rolling performance during quiet segments.

Package Contents and Installation Hardware

Everything needed for a single-subwoofer install ships in the box, so the upgrade is a one-purchase job rather than a parts run.

• What's in the Box: 4 casters, 4 protection sheets, 1 hex key — complete installation kit, no extra hardware required
• Washer Plate: Included per caster — distributes load and protects the cabinet finish
• Each caster includes a washer plate designed to distribute weight evenly and maintain cabinet integrity.
