Safemark Expands Marshall Portable Speaker Lineup for Hotels

Kilburn III, Stockwell II, and Tufton Bring Premium Sound to Every Corner of the Guest Experience

ORLANDO, FLA., April 28, 2026 — Today’s hotel guests don’t just expect great sound in their room — they expect it everywhere. Safemark, a global leader in guest room security and hospitality solutions, is proud to announce the addition of three Marshall portable Bluetooth speakers to its hospitality lineup: the Kilburn III, Stockwell II, and Tufton. These new offerings expand Safemark’s Marshall portfolio beyond in-room fixed audio, giving hotels a range of portable, premium sound solutions — from poolside lounges and outdoor terraces to spa suites and event spaces.

“Guests already expect the basics — a comfortable bed, a clean room, and good climate control. We want to help hotels go beyond that. Marshall speakers give properties a way to create moments guests actually remember and talk about. That’s what drives the five-star review, the repeat booking, the recommendation to a friend.”

— John Foley, Vice President of Sales, Safemark

Marshall Kilburn III — Premium Portable Power

The Kilburn III is Safemark’s most powerful portable Marshall offering, delivering an immersive 360° True Stereophonic audio experience that fills any space with rich, detailed sound. With over 50 hours of battery life on a single charge — more than enough for a full weekend of events — the Kilburn III is designed for hoteliers who demand both performance and reliability. Its IP54 dust and water-resistant construction makes it equally at home at the pool deck, in-room, or at a property event.

• 50+ hours of portable playtime on a single charge 
• IP54-rated dust and water resistance 
• Dynamic Loudness for perfectly balanced audio at any volume 
• Auracast™ wireless connectivity and built-in phone charging bank

Marshall Stockwell II — Compact Versatility

Weighing just over 2lbs, the Stockwell II is the ideal grab-and-go speaker for hospitality environments where portability is key. Its guitar-inspired carry strap and pint-sized frame make it effortless to move between rooms, spa areas, or event setups. Despite its compact size, the Stockwell II packs three Class D amplifiers driving a subwoofer and dual tweeters in a bass-reflex enclosure, delivering a 360° True Stereophonic experience that punches well above its weight.

A 3-way driver system including a 40W subwoofer, dual 15W full-range drivers, and a 10W tweeter, complemented by a rear-facing mid-range driver, delivers true 360° Blumlein stereo sound up to 102dB. Quick charging means 20 minutes plugged in gets guests 4 hours of continuous play — perfect for event setup turnaround.

• 20+ hours of portable playtime on a single charge 
• Rear-facing mid-range driver for true 360° Blumlein stereo sound 
• 102 dB maximum SPL — fills large indoor and outdoor spaces
