HIGH - IMPEDANCE/CONSTANT - VOLTAGE SYSTEM: The Programme 1LT features an internal line-matching transformer with five power/impedance selections for 100 volt line. In speaker systems anything over 32Ω is considered high impedance. Use of constant-voltage distribution in installation increases the impedance to the desired level at the speaker location. With the line impedance well above the nominal speaker impedance, power loss in long speaker lines is minimised. Smaller wire can be used without excessive power loss. The five switchable power tappings are 0.6W,1.25, 2.5, 5.0 and 10 watts accessed through an external connecting block at the rear of the cabinet.

1LT specifications

The Wharfedale 1LT is a compact bookshelf speaker that delivers impressive audio performance, catering to both casual listeners and audiophiles alike. Known for its exceptional build quality and advanced acoustic technologies, the 1LT series brings Wharfedale's rich heritage of speaker craftsmanship into a more accessible format.

One of the key features of the Wharfedale 1LT is its 5-inch woven Kevlar bass driver. This unique material is not only lightweight but also offers excellent rigidity, ensuring that the speaker can reproduce low frequencies with precision and clarity. The Kevlar construction minimizes distortion, allowing for a cleaner and more powerful bass response, which is ideal for a variety of musical genres.

Complementing the bass driver is a 1-inch soft dome tweeter that excels in delivering a smooth and extended high-frequency response. The tweeter's design allows it to reproduce delicate details in music while maintaining an overall balanced sound profile. This combination of drivers results in a well-integrated soundstage, making the 1LT suitable for both music and movie audio experiences.

The cabinet design of the Wharfedale 1LT is another highlight. Constructed from MDF (Medium Density Fiberboard), it significantly reduces unwanted resonance, thus improving sound clarity. The speakers also feature a rear-firing bass port, which enhances low-frequency performance and allows for flexible placement within a room. The thoughtful engineering ensures that even in smaller spaces, the 1LT can deliver dynamic sound without compromising on quality.

In terms of connectivity, the Wharfedale 1LT is equipped with standard binding posts, making it compatible with a wide range of amplifiers and receivers. This versatility simplifies integration into existing audio setups and offers users the flexibility to choose their preferred equipment.

Overall, the Wharfedale 1LT is a remarkable speaker that balances performance, design, and value. With its advanced driver materials, robust cabinet construction, and user-friendly connectivity, it stands out as an excellent choice for anyone seeking high-quality sound in a compact package. Whether used for casual listening or serious audio enjoyment, the Wharfedale 1LT is sure to impress with its engaging acoustic performance and timeless aesthetics.
