Our Review


When we consider the immersive experience that a home theater system promises, the significance of a potent subwoofer cannot be overstated. It's the cornerstone of deep, palpable bass that pulls you into the heart of the action, be it a high-octane car chase or the subtle nuances of a symphony. The Definitive Technology Fully Enclosed In-Wall Subwoofer (IWSub 10/10) is a specimen designed to blend seamlessly into your living space while promising to deliver the kind of bass that is both felt and heard.


Aesthetics and Build

The IWSub 10/10 is discreetly charming. Its white facade and minimalistic grille design are meant to integrate into the walls of your home without drawing undue attention. The build quality is robust, employing a sealed medite box that ensures the unit is not just another wall fixture but a solid piece of audio engineering.

Installation Requirements

This subwoofer demands a commitment to placement, requiring installation between wall studs. While this may seem daunting, it's a one-time effort that pays dividends in space efficiency and acoustic performance. For those building a new home or renovating, the IWSub 10/10 can be planned into the design with ease.

Space Efficiency

The in-wall nature of this system cannot be praised enough for those who value the aesthetics of their living space. It eradicates the need for bulky floor-standing units, leaving your room feeling open and uncluttered—a boon for modern minimalist design sensibilities.


Fully Enclosed Enclosure

A fully enclosed design is not just a matter of containing the driver; it's about optimizing the acoustic environment in which the subwoofer operates. By preventing sound from bleeding into other rooms or cavities in the wall, the IWSub 10/10 ensures that all the audio is directed into the living space, which enhances the listening experience.

Compatibility with SubAmp 600

This subwoofer is designed to be paired with the SubAmp 600, a dedicated external amplifier that does more than just power the system. It offers fine-tuning controls for phase, volume, and crossover, allowing users to tailor the sound to their room's acoustics and personal preferences.

Customization Options

Definitive Technology understands that aesthetics matter. The removable grilles and bezel can be painted to match any wall color, ensuring the subwoofer complements the room's decor rather than clashing with it.


Audio Quality

The IWSub 10/10 excels in delivering a bass response that is both smooth and authoritative. Movies are imbued with an extra layer of realism, while music benefits from a foundation of bass that supports rather than overwhelms. The dual 10-inch drivers—one active and one passive—work in unison to produce bass that is devoid of boominess, ensuring that what you hear is as close to the artist's or director's intention as possible.

Frequency Response

With a frequency response that dips down to 16 Hz, this subwoofer is capable of reproducing even the lowest of lows. This is the kind of performance that is felt in the chest and through the floor, bringing an extra dimension to the audio experience.

Power Handling

The IWSub 10/10's power handling, when matched with the SubAmp 600, is robust. It delivers ample headroom for dynamic movie soundtracks without distortion, ensuring that even at high volumes, the audio remains crisp and clear.


DIY vs. Professional Installation

For the DIY enthusiast, installing the IWSub 10/10 can be a rewarding project, but it is not without its challenges. Precision is key, and the uninitiated may find the task daunting. Professional installation is recommended for those who are less confident in their handyman skills, ensuring optimal performance and a polished finish.

Installation Process

The installation process involves selecting the right location, cutting into the drywall, securing the unit between studs, and connecting it to the SubAmp 600. It's a straightforward process for a professional installer, and the result is a subwoofer that looks and sounds as if it were an integral part of the home.

Pros and Cons

- Space-saving in-wall design.
- Fully enclosed for optimal performance.
- Customizable appearance.
- Deep and impactful bass for movies and music.

- Installation may be intimidating for some.
- Fixed placement limits flexibility.
- Not suitable for temporary living situations.

Use Cases

Home Theater Enthusiasts

For those with dedicated home theater spaces, the IWSub 10/10 is a dream. It delivers the kind of performance that elevates movie nights into cinematic events, all while maintaining the aesthetic integrity of the space.

Audio Purists

High-fidelity audio reproduction is about transparency and fidelity to the source material. This subwoofer, with its clean and accurate bass, meets the criteria for purists who demand nothing but the best from their audio systems.

Space-Conscious Consumers

Those living in smaller spaces or who prefer a minimalist design will appreciate the IWSub 10/10's ability to disappear into the wall, ensuring that living space is maximized without sacrificing audio quality.

Comparison to Freestanding Subwoofers

Compared to freestanding subwoofers, the IWSub 10/10 offers a different proposition. While it may lack the placement flexibility of its freestanding counterparts, it compensates with its space-saving design and the ability to deliver comparable, if not superior, acoustic performance due to its controlled enclosure.

Price and Value Proposition

The IWSub 10/10 is not the cheapest option on the market, but the value proposition lies in its blend of performance, aesthetics, and space efficiency. When considering its long-term presence in a home, the investment is justifiable.

Final Thoughts
