The core promise of the THOR IW-SUB10 lies in its ability to generate profound, accurate low frequency energy, replicating the sub-harmonic information essential for truly immersive home cinema and deeply satisfying music playback. Earthquake Subwoofers smaller than 10 inches struggle to deliver the palpable impact required for high-end home theater; the THOR IW-SUB10 meets this criterion with a sophisticated driver complement designed for maximum performance within significant physical constraints.

At its heart are two proprietary 10-inch components working in concert within a sealed enclosure: a patented SWS (Shallow Woofer System) driver and a patented SLAPS (Symmetrically Loaded Audio Passive System) passive radiator. The SWS driver is engineered for remarkable linear movement, boasting a peak-to-peak excursion of 2.5 inches, which enables it to move significant amounts of air despite its shallow profile. The SWS-10X driver is pneumatically coupled to the SLAPS passive radiator, which augments the system’s low frequency output and efficiency. This technological synergy allows the THOR IW-SUB10 to achieve an impressive frequency response, extending down to 20Hz, ensuring the reproduction of the deepest audible frequencies.

Beyond its sonic capabilities, the THOR IW-SUB10 is fundamentally engineered for invisibility. Its physical design meticulously addresses the requirements for seamless integration into standard home construction, ensuring it can deliver powerful bass without any visual footprint. A cornerstone of this design is its remarkably shallow mounting depth, measuring just 3.75 inches (95mm). This allows the subwoofer to be installed within the confines of a standard 2×4 stud wall, a critical factor for compatibility with typical North American construction practices and for facilitating a straightforward retrofit into existing homes.

Crucially, the IW-SUB10 incorporates an integrated, sealed back box. This enclosure is not merely a housing; it is a carefully engineered acoustic component constructed from reinforced, high-density materials like high-temperature PVC, designed to be non-resonating. Unlike open-back in-wall speakers that rely on the unpredictable volume and acoustic properties of the wall cavity, the THOR’s sealed box provides a controlled, predictable air volume for the drivers to work against. This ensures consistent performance regardless of the specific wall construction, and, critically, prevents the subwoofer from unduly loading the wall cavity, which can excite unwanted resonances and rattles. The back box itself is heavily reinforced with internal bracing structures, including front-to-back bridges and crisscrossed ribs, to ensure rigidity and prevent flexing under pressure, further contributing to its low-resonance characteristics.

Aesthetic integration is paramount for an invisible speaker. The IW-SUB10 ships with a standard white metal mesh grille that is paintable, allowing it to blend with most common wall colors. Recognizing the need for perfect visual matching, Earthquake Sound also includes frames and cloth specifically designed for creating custom fabric grilles. This thoughtful inclusion allows installers or homeowners to use virtually any fabric type or color to achieve a perfect match with the surrounding décor, directly addressing the WAF without requiring additional purchases or custom fabrication. This provision of multiple grille solutions out of the box significantly simplifies the final integration step and removes a common barrier to achieving true invisibility. While primarily intended for in-wall use, the design offers some flexibility in placement. With some modifications, the unit can also be integrated into ceilings, custom furniture, or the floor and covered with a heater register.

The ability of the THOR IW-SUB10 to deliver deep bass from a shallow enclosure is not accidental; it is the direct result of two core proprietary technologies developed and patented by Earthquake Sound: the Shallow Woofer System (SWS) and the Symmetrically Loaded Audio Passive System (SLAPS). The ownership and implementation of these patented designs provide a distinct technological advantage, differentiating the IW-SUB10 from competitors relying on conventional driver approaches.

Together, the patented SWS and SLAPS technologies form a synergistic system perfectly suited to the demands of the IW-SUB10, achieving high excursion, low distortion bass efficiently augmented for deep frequency extension within a small, sealed volume, without port noise distortion, all within a shallow, install-friendly profile.
