Minx MIN22 installation
Last updated: February 2, 2023 04:43. Revision #10924
1. Firstly, ensuring to match the polarity/colour coding, connect the supplied speaker terminals to the speaker outputs of your amplifier or receiver
by unscrewing the ends, and securing the speaker cable in the available hole on each terminal. These terminals can then be installed into the rear
of the MIN22 with the cables connected.
2. If mounting the MIN22 speakers to a wall you will need to attach the included keyhole bracket using the mounting screw to the rear of the
speaker.
3. Alternatively, we offer several other mounting solutions including a pivoting wall mount, desk stand, and floor stand.

Minx X301 unboxing and installation
Last updated: February 2, 2023 04:43. Revision #10923
Unboxing your Minx X301 subwoofer.
Follow the diagram and take care when unboxing your Minx X301 so not to damage the speaker cone.
Installation of your Minx X301.
Dependent on your desired setup, there are a few different ways to connect your Minx X301 subwoofer.
1. If you are using an amplifier with a L+R pre-out then use the left and right line input connections to connect your Minx X301.
2. If you are using a receiver, or amplifier with a dedicated sub out then connect the Minx X301 using the left channel (LFE/Sub) input.

11
3. Once connected you can decide where to position your subwoofer. As low frequency content is largely unidirectional, you can experiment to find
a place that suits your setup.
4. Use the crossover frequency, phase, and volume controls to adjust the subwoofer output to fit with the rest of your system, and your
requirements.

Frequently asked questions
Last updated: February 2, 2023 04:43. Revision #10921
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.

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.
No sound through subwoofer.
• Check that the amplifier is turned on.
• Ensure that the correct input source is selected on the amplifier.
• Check that the subwoofer is turned on.
• Confirm that all connections between the amplifier and subwoofer are secure.
• Check that the connections between the source equipment and amplifier are secure.
• Check that the volume control is set correctly on the amplifier.
• Check that the volume control is set correctly on the subwoofer.
There is no power to the subwoofer.
• Confirm that the connection to the mains is secure.
• Confirm that the plug is switched on at the wall.
