Mass Loading, Fitting Plinths & Floor Spikes

MASS LOADING

These loudspeakers are designed to be mass loaded, if wished, to lower the centre of gravity and improve stability, resulting in improved sound quality. To do so, remove the 4 screws securing the access plate to the bottom of the loudspeaker. The loading volume can be filled with sand (which must be dry), or propriety materials available for such purposes from your retailer. Feel free to experiment with the volume of loading material used, to achieve optimum bass performance and stereo imaging. (See fig. 2)

FITTING PLINTHS & FLOOR SPIKES

Attach the two plinth sections using the screws and hex tool provided. These loudspeakers are designed to perform best with the carpet piercing spikes fitted, for optimum stability. These are supplied, along with locking wheels, and should be inserted into the threaded holes in the base of the cabinet. Level the speaker, using the hex tool and then tighten the locking wheels firmly but without using undue force. Spike locating cups are provided in the accessory pack and these may be used to protect sensitive floor surfaces. (Shown also in fig. 2)

Warning:

Ensure that the spikes are levelled and that the lock nuts are tightened firmly. The spikes should be pushed through the carpet to locate into the flooring surface by applying pressure to the top of the cabinet. Failure to do so could render the speaker unsteady and result in damage or injury should it be knocked over.

INSTALLATION

To avoid potential damage to your loudspeaker, ensure that the amplifier is switched OFF prior to connecting or disconnecting any cables. Before switching on double check that all connections are secure and that polarity is correct.

CONNECTION IN SINGLE WIRE MODE

Using the supplied link cables, connect the high frequency (HF) and low frequency (LF) terminals respectively, as shown. These must be removed to Bi-wire the speakers - see section entitled Connection in Bi-wire Mode. For optimum performance in single wire mode, loudspeaker cable connections from the amplifier should be made to the high frequency (HF) terminals of the loudspeaker: (See fig. 3)

•The positive (plus) terminal on the amplifier left channel (marked + or coloured red) must be connected to the positive

HF terminal on the left speaker. The left speaker is the one on the left as you look at the stereo pair from your listening position.

•The negative (minus) terminal on the amplifier left channel (marked - or coloured black) must be connected to the negative

HF terminal on the left speaker.

•Repeat this connection process for the right speaker. Remember that the positive (+ or red) on the amplifier must be connected to the positive (+ or red) on the speaker and the negative (- or black) to negative.

•Select a signal source, such as a CD player; switch on the amplifier and slowly turn up the volume control to check that both loudspeakers are reproducing bass and treble information.

DC10A specifications

The Tannoy DC10A is a flagship loudspeaker from the British audio company Tannoy, renowned for its commitment to high-fidelity sound reproduction. A distinctive feature of the DC10A is its Dual Concentric driver design, which places the high-frequency driver at the center of the low-frequency driver, ensuring a point source of sound. This innovative design helps maintain phase coherence and delivers a well-integrated soundstage, providing a listening experience that is both immersive and precise.

One of the standout characteristics of the DC10A is its impressive frequency response. The speaker is capable of reproducing audio frequencies from 36 Hz to 40 kHz, making it suitable for a wide variety of music genres and audio applications. This extensive frequency range allows listeners to experience the subtle nuances in both high and low frequencies, ensuring that every instrument and vocal is rendered with clarity and depth.

The cabinet of the DC10A is meticulously crafted from high-quality materials, further enhancing its aesthetic appeal and acoustic performance. The speaker enclosure is designed to minimize resonances that could color the sound. Additionally, the cabinet features a rear-firing port, which helps to enhance low-frequency response and improves overall bass performance.

The DC10A also showcases advanced crossover technology, which divides the audio signal into different frequency ranges to be handled by the respective drivers. This ensures that each driver operates within its optimal range, providing a more accurate and dynamic sound reproduction. The precise engineering of the crossover allows for smooth transitions between the low and high frequencies, contributing to the speaker's overall natural sound signature.

Another significant aspect of the Tannoy DC10A is its power handling capability. The speaker can handle up to 500 watts of peak power, making it ideal for both home listening and professional environments. This ensures that even at high volumes, the speaker maintains sound quality without distortion.

In summary, the Tannoy DC10A is a sophisticated loudspeaker that incorporates innovative technologies and high-quality materials to deliver exceptional audio performance. Its Dual Concentric driver design, broad frequency response, sturdy cabinet construction, and advanced crossover technology make it a standout choice for audiophiles and professionals alike. Whether for music appreciation or critical listening, the DC10A provides a sound experience that is both engaging and accurate, affirming Tannoy's legacy in the world of high-fidelity audio.
