5. Connecting

Connecting your Linear Centre to an amplifier is fundamentally a simple process, however, there are some choices to be made and issues to consider concerning connection mode, connectors and cable type.

Linear Centre is fitted with two pairs of binding- post terminals - one pair each for the low frequency and high frequency drivers. Two pairs of terminals enables Linear Centre to be connected conventionally (single wire), bi- wired or bi-amplified. As supplied, the high and low frequency terminals are connected together by metal shorting links ready for conventional connection.

The terminals can accept either stripped wires, spade connectors, or 4mm plugs. Each of these termination methods is potentially equally effective and the choice is likely to be influenced by type of speaker cable used. Your dealer, distributor or cable manufacturer will be able to offer advice.

Conventional [single wire] connection

Conventional connection requires that the shorting links remain in place between the high and low frequency terminals. Simply connect the speaker cable to either pair of terminals ensuring correct connection polarity as described below.

Bi-Wire Connection

Bi-wiring separates the low and high frequency connections and can provide enhanced sound quality. A second set of cables (or alternatively, a multi-way bi-wire cable) is required. The shorting links should be removed and stored for any subsequent single wire use.

The two cables for each speaker should be connected in parallel to the amplifier terminals. At the speaker, one cable should connect to the high frequency terminals and one to the low frequency terminals. Ensure correct connection polarity as described below.

Bi-Amplifier Connection

Bi-amplifier connection adds a second power amplifier to the system so that high and low frequency sections have dedicated amplifiers. Significantly enhanced sound quality is possible. One stereo amplifier should be connected to the high frequency terminals of each speaker and a second stereo amplifier connected to the low frequency terminals. The shorting links should be removed and stored for any subsequent single wire use. Ensure correct connection polarity as described below. Follow the amplifier manufacturer’s guidance on connecting the amplifier input signals.

The shorting links must be removed for bi-amplifier connection. Failure to do so will likely result in damage to the amplifiers.

Connection Polarity

It is important when connecting speakers to ensure that each terminal is connected with the correct polarity. Positive speaker terminals should always be connected back to amplifier positive terminals, and negative speaker terminals connected back to amplifier negative terminals. Performance will be seriously degraded if connections are made with incorrect polarity.

Take care when connecting cables not to touch the negative and positive terminals together and “short-circuit” the amplifier. Make connections with the amplifier switched off.

Choice of cable type will be influenced by the characteristics of other components in your hi-fi system and your dealer or distributor will be able to advise. Even so, there are some simple guidelines to consider:

•Cable runs to should be kept as short as possible.

•Short cable runs are especially important if the cable is of relatively small cross-sectional-area.

•If the cable is advertised as “directional” care should be taken to ensure that its orientation is as recommended.

Linear Centre specifications

The Acoustic Energy Linear Centre is an innovative loudspeaker system that represents a significant leap forward in audio technology. Designed for both audiophiles and casual listeners, this cutting-edge device offers exceptional sound quality and a unique design that elevates any audio experience.

At the heart of the Acoustic Energy Linear Centre is its impressive driver configuration. The speaker features a dual 5-inch woofer arrangement that enhances low-frequency response, ensuring a balanced sound that fills the room with rich, vibrant audio. Complementing these woofers is a precision-engineered 1-inch tweeter, which produces crystalline highs that add clarity and detail to music, movies, and other media.

One of the standout characteristics of the Linear Centre speaker is its advanced cabinet design. Constructed from high-density MDF, the cabinet minimizes unwanted resonances and vibrations, resulting in cleaner sound reproduction. Moreover, the speaker's unique curved design not only provides aesthetic appeal but also helps to optimize acoustic performance by reducing standing waves within the enclosure.

The Linear Centre is equipped with a range of technologies that contribute to its superior sound quality. One notable feature is the dual port bass-reflex system, which enhances the speaker's low-frequency output while maintaining precision. This design allows for deeper bass without compromising overall sound clarity, making it an excellent choice for home theater setups as well as music playback.

Additionally, Acoustic Energy employs a sophisticated crossover network in the Linear Centre, which is finely tuned to ensure seamless integration between the woofers and tweeter. This results in a coherent soundstage, allowing for a more immersive listening experience. The speaker's impedance and sensitivity specifications are also optimized for compatibility with a variety of amplifiers, making it a versatile addition to any audio system.

Overall, the Acoustic Energy Linear Centre is a remarkable speaker that combines state-of-the-art technology with elegant design. Its exceptional sound quality, innovative features, and thoughtful engineering make it an ideal choice for anyone seeking to enhance their audio experience, whether for movies, music, or more. With the Linear Centre, listeners can expect profound depth, clarity, and an enveloping sound field that transforms ordinary audio into an extraordinary experience.
