Klipsch RSM-400 Indoor/Outdoor Speakers (Pair)

Legendary Klipsch Sound. Compact Design. Built for the Outdoors.

Bring the unmistakable clarity and energy of Klipsch to your patio, deck, porch, or outdoor entertainment space with the Klipsch RSM-400 Indoor/Outdoor Speakers.

Featuring 4-inch injection-molded polypropylene woofers and precision ¾-inch titanium compression drivers, the RSM-400 delivers clear, detailed sound and impressive musical performance from a remarkably compact, weather-resistant enclosure.

Designed for customers who appreciate premium audio without bulky speakers, the RSM-400 combines Klipsch's legendary horn-loaded technology with exceptional durability and installation flexibility.

Exceptional Sound in a Compact Design

The RSM-400 brings the dynamic, engaging sound Klipsch is famous for to smaller outdoor listening areas.

Its 4-inch woofer delivers natural vocals and articulate midrange performance, while the titanium compression driver provides crisp, detailed high frequencies.

Klipsch's modified Tractrix horn helps distribute sound evenly throughout your listening area, making these speakers an excellent choice for background music, outdoor dining, and entertaining friends and family.

With 85dB sensitivity, the RSM-400 offers enjoyable musical performance when paired with appropriately matched amplification.

Precision Horn Technology for Outstanding Clarity

At the heart of the RSM-400's performance is Klipsch's advanced horn-loaded driver design.

The ¾-inch titanium compression driver is coupled to a 90° × 90° modified Tractrix horn, providing wide, consistent sound coverage and exceptional high-frequency detail.

This combination helps maintain clarity and intelligibility across your outdoor listening area, allowing music to remain engaging without excessive volume.

Unlike the larger RSM models, the RSM-400 features a sealed enclosure, making it particularly well suited for compact installations.

Engineered for the Elements

The RSM-400 features a rugged, paintable all-weather ABS enclosure designed for demanding indoor and outdoor environments.

Its IPX6-rated construction provides excellent resistance to rain and water exposure, while secure grille set screws help keep everything firmly in place.

The included adjustable mounting brackets allow flexible positioning, making installation practical beneath eaves, on exterior walls, or around covered patios and decks.

Available in black or white, the RSM-400 complements a wide variety of architectural styles.
