MARROW SPEAKER
Designed for adventurers who demand uncompromising audio fidelity in the most unpredictable environments, this speaker redefines the boundaries of portable sound. Engineered with a rugged, acoustically inert chassis to withstand high-impact urban transit, its form factor remains fluid and intuitive, echoing the organic movement of coastal landscapes. Inside, a precision-tuned driver array utilizes active resonance management to achieve stadium-level sound pressure in a device no larger than a smartphone, ensuring your soundtrack remains as dynamic as your lifestyle.
YEAR
2026 6-week project
SOLO PROJECT
Completed independently from research through final concept.
DESIGN GOAL
Create a phone-sized audio powerhouse for a life in constant motion, blending street-level toughness with coastal fluidity to deliver pristine, stadium-level sound anywhere.
DESIGN PROMPT
Create a sustainably responsible product that expresses a unique and purposeful form.
Pure Resonance
The industry forces a choice between size and sound, trapping power behind unnecessary bulk. We are breaking that compromise. By ditching bloated design for rugged, compact precision, we’ve created an acoustic powerhouse built for the friction of the streets and the volatility of the coast. This is stadium-level impact in a frame that refuses to be weighed down.
Portable speakers prioritize size over sound quality, why not have both ?
Designer can only achieve two out of three core goals: deep bass, small enclosure size, and high output efficiency. this is called Hofmann’s iron law
— Josef Anton Hofmann
We set out to design the speaker that would shatter Hofmann’s law.
Building on that foundation, we launched into rapid 15-minute whiteboard sketching sessions. These quick bursts of initial ideation pushed us to translate our component map into physical shapes. Iterating fast allowed us to discover dynamic silhouettes that balanced rugged armor with a clean, pocketable form.
Our process began at the whiteboard, talking through the layout of core components within a smartphone-sized footprint. We let the protective exterior organically wrap around this internal architecture. This natural, component-driven form ensures intuitive interaction, perfectly bridging urban grit with coastal freedom.
