What’s included with the Minx C46?
Last updated: Enero 19, 2023 05:43. Revision #8468
1. 1 x Minx C46 Ceiling Speaker.
Installation instructions
-
Firstly use the included template to mark the position for the mounting hole at the selected location.
Note: We recommend the use of a 75mm (3”) downlight hole saw
-
When mounting speakers flush to a ceiling or wall, ensure that there is enough depth/clearance within the respective cavity. For the Minx C46 you will require a minimum clearance of 95mm (3 ¾”).
-
Connect the RED positive (+) and BLACK negative (-) speaker cables to the relevant terminals on the Minx C46. It is important that these are matched correctly.
-
Next, press the metal clips upwards and fit the two longer arms into the ceiling hole.
-
Push the speaker upwards until firmly within the mounting hole.
Technical specifications
Sensitivity (SPL)
86dB (2.83 Vrms input)
Frequency Response
120Hz – 20kHz
Impedance
8 Ohms compatible.
Recommended amp power
25-200W. Using a high powered amplifier lower down its volume scale results in
lower distortion and better sound. If you hear a distorted sound or mechanical
‘crack’ as the speakers hit their end stops, you are playing the speakers too
loud and this may cause damage. With an AVR the Minx C46 speakers should be
set to ‘small’ with a crossover frequency of 140Hz. In this configuration,
power handling is considerable increased.
Drivers
1 x 2.25” woofer.
Speaker Dimensions (H x W x D)
98 x ø 88mm (3.6 x ø 3.4”)
Weight
0.46kg (1.01lbs)
Frequently asked questions
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 addedrepresents a doubling of
power.
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
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.
