Bowers & Wilkins 803D4 45.9" Floor Standing Speakers Rosenut
Product Description
The Bowers & Wilkins 803D4 is a marvel of compact engineering, marrying technical innovation with space-conscious design. Its Turbine Head and decoupled midrange cone ensure clarity and precision, making it ideal for audiophiles who demand accuracy in sound reproduction. This speaker is not just a smaller sibling in the 800 Series Diamond range; it boasts its own unique strengths in delivering a detailed soundstage.
With its Diamond tweeter and Continuum cone FST midrange, the 803D4 delivers a frequency response from 19Hz to 28kHz, while the Matrix bracing reduces resonance for an authentic listening experience. The 3-way vented-box system, featuring dual 180mm Aerofoil cone bass units, ensures that the bass is both powerful and controlled, making it perfect for a dedicated theater space or a refined living room setup.
The 803D4’s reverse wrap cabinet and solid aluminum bass pods set it apart, offering both structural integrity and aesthetic appeal. This attention to detail ensures a sound quality that's as beautiful as the speakers themselves. For those in Houston, Dallas, or Austin, MODIA offers an opportunity to experience these speakers firsthand, with professional installation and calibration available to optimize your setup.
Whether you’re upgrading your existing system or building a new one, stop by our Texas showrooms for a personal demonstration. Discover how the 803D4 can transform your listening experience with the expertise and service that only MODIA can provide.
