Cambridge Audio SX-50 Standmount Speakers

Product Information

The SX-50 Standmount Speakers are a pair of speakers that come with an installation guide, 8 rubber pads, and 2 foam bungs. The front panel of each speaker features a 25mm silk dome tweeter and a 5.25-inch treated paper cone driver. The rear panel includes a bass port and +/- speaker connection terminals. The speakers have a sensitivity of 87dB, a frequency response of 50Hz – 22kHz, and an impedance of 8 Ohms. The recommended amplifier power is between 10-100 watts, and the speakers weigh 3.0kg (6.6 lbs).

Product Usage Instructions

1. Using high-quality speaker cables, connect the SX-50 stand-mount speakers to the speaker terminals on your amplifier. Make sure to match the polarity of each connection.
2. For the best results, use speaker stands to mount the SX-50 speakers. Alternatively, place the speakers on a shelf and leave at least a 5cm space behind the rear of each speaker.
3. If placing the speakers on a desk or close to a wall, use the included foam bass tuning bungs by placing them into the rear port of each speaker to reduce low-frequency output.
4. When positioning, ensure that the distance between the speakers and the listening position is equal. Experiment with placement until you find a solution that works for your space.

Frequently Asked Questions

1. What is meant by speaker sensitivity?
   Speaker sensitivity refers to how loud a speaker can get with a given amount of power. The higher the sensitivity rating, the louder the speaker can play with less power.

2. What is a crossover?
   A crossover is an electronic circuit that filters and separates the audio signal into different frequency ranges for the tweeter and woofer of a speaker.

3. What is impedance?
   Impedance is the measure of resistance at a given frequency, measured in Ohms. It is important to consider when setting up an audio system as it determines the load placed on an amplifier by the speakers.

Introduction

• Thank you for purchasing these Cambridge Audio SX-50 stand-mount loudspeakers. We hope that you enjoy many years of listening pleasure from them. Your loudspeakers can only be as good as the system it is connected to. Please do not compromise on your amplifier or cabling. Naturally, we particularly recommend amplification from the Cambridge Audio range, which has been designed to the same exacting standards as our loudspeakers. Your dealer can also supply excellent quality speaker cables to ensure your system realizes its full potential.
• Thank you for taking the time to read this manual; we do recommend you keep it for future reference.

Installation instructions

Last updated : января 19, 2023 01:56. Revision #8410

1. Firstly, using high-quality speaker cable connect the SX-50 stand mount speakers to the speaker terminals on your amplifier. Ensure that you pay close attention to match the polarity of each connection.
2.  For the best results we would recommend using speaker stands to mount your SX-50 speakers. Alternatively, the speakers can be placed on a shelf, and in either case we would suggest leaving at least a 5cm space behind the rear of each speaker.
3. If placed on a desk, or close to a wall you may benefit from using the included foam bass tuning bungs. These can be placed into the rear port of each speaker to reduce the low frequency output.
4. Finally, when positioning, we would suggest that the distance between speakers and the listening position is equal. However, we would encourage experimentation until you find a solution that works for your space.

Frequently Asked Questions

Last updated: января 19, 2023 01:56. Revision #8412

What is meant by speaker sensitivity?

Speaker sensitivity is the level produced by the speaker at one meter, when supplied with one watt of power from an amplifier. It’s a way of describing how well the speaker produces acoustic energy, based on a given input. The level is measured in dB SPL – this shorthand for ‘sound pressure level’ – sound is basically fluctuations in air pressure, so any time you see SPL, this means ‘sound in the real world’. So, let’s say we have a speaker with an 87dB sensitivity, and a speaker with a 90dB sensitivity – the 90dB speaker is going to be considerably louder, as every 3dB added represents a doubling of power.

What is a crossover?

Most speakers will have multiple drivers. A driver is sometimes called a transducer, which is a device that turns one type of energy into another – in this case, electrical energy to sound energy. In a loudspeaker, it is often the case that we might want multiple drivers – one to handle low-end, one to handle the mid-range, and one to handle the treble. This latter driver is often called a tweeter. To get the benefit of this arrangement, we need to split the signal into different frequency components. The circuit that does this is called a crossover.

What is impedance?

You will often see impedance mentioned when researching speakers, and amplifiers. Impedance is basically resistance measured at a given frequency, given as a value in Ohms (Ω), and is incredibly important to consider when setting up an audio system as it determines the ‘load’ placed on an amplifier by the speakers.
For example, let’s say we have an amplifier that is rated to deliver 100W into an 8Ω speaker load. If we were to then use speakers with an impedance of 4Ω with the same amplifier, the amp would then need to supply 200W as a halving of the impedance results in a doubling of the required power due to the reduction of the load on the amplifier.
In a situation such as this, if the amp can’t supply the required power for a lower impedance, then it can result in overheating, and damage to the amplifier and speakers.
For this reason, it is important to pay attention to amplifier specifications, and suggested impedance ratings.

Troubleshooting

Last updated: января 19, 2023 01:56. Revision #8413 No sound through one or both channels.

• Check that the amplifier is turned on.
• Ensure that the correct input source is selected on the amplifier.
• Confirm that all connections between the amplifier and loudspeakers are secure.
• Check that the connections between the source equipment and amplifier are secure.
• Check the polarity of the loudspeaker connections.
• Check that the volume control is set correctly on the amplifier.

There is distorted or inconsistent sound.

• Confirm that all connections between the amplifier and loudspeakers are secure.
• Check the polarity of the loudspeaker connections.
• Check that the connections between the source equipment and amplifier are secure.
