Micca COVO-S 2-Way Passive Bookshelf Speakers
Introduction
Thank you for purchasing the Micca COVO-S Concentric Driver Bookshelf Speaker! This product has been designed for optimal audio reproduction performance in a variety of home entertainment configurations, with accuracy, clarity, and impact that discerning audiophiles listen for.
Please take the time to become familiar with the COVO-S and the placement options as detailed in this manual.
General Recommendations
Height – For stereo listening from a fixed listening area, the COVO-S should ideally be placed at the ear-level of the listener, with the listener comfortably situated in the listening location.
Separation – The distance between a pair of COVO-S speakers should be shorter than the distance from the speakers to the listener. Tilt the two speakers inward toward the listener slightly for best results.
Orientation – The concentric driver design of the COVO-S speaker allows it to be used in either vertical or horizontal orientation without significant effect to performance.
Location – Place the COVO-S along a wall or near the corner of a room for best results. Since the speakers are rear ported, keep the speakers at least 4 inches away from the wall.
Usage-Specific Recommendations
Bookshelf Speakers
When placed on bookshelves, it is important to keep both speakers at the same height. Avoid placing the speakers at different heights as this will degrade the sound. Speaker height should be selected so that it is as close to ear level as possible while considering whether listeners will be seated or standing in the listening area.
Stereo Speakers on Stands
When used with speaker stands, it is important to select speaker stands that place the speakers to the ear level of the listener. Do this by measuring the height of the listener’s ear when seated in the listening area, and subtracting 3 inches. For example, if the listener’s ear is measured at 36 inches from the floor when seated, select speaker stands that are approximately 33 inches high.
Desktop Near-field Monitor
The COVO-S can be used as desktop/near-field monitor speakers, such as when placed to the either side of a display or mixing console. If the COVO-S cannot be located near ear level, foam monitor isolation wedges can be used to slightly tilt back the speakers and to decouple the speakers from the desk surface. The COVO-S is shielded and can be safely used near to CRT displays.
Speaker Wire
The COVO-S should be connected to the amplifier with good quality oxygen-free copper speaker wire for best performance.
The gauge or thickness of the speaker wire can affect the performance of the COVO-S. Always choose a speaker wire of the appropriate gauge to prevent excessive speaker wire resistance. Using an undersized speaker wire can result in lose of volume, detail, and dynamic range.
Please select speaker wire for the COVO-S based on the following minimum recommendations:
- 50′ or less – 16 Gauge 2 Conductor
- 50′ – 80′ – 14 Gauge 2 Conductor
- 80′-120′ – 12 Gauge 2 Conductor
- 120′-200′ – 10 Gauge 2 Conductor
Amplifier Connection
Amplifier speaker output terminals are typically color coded with black for negative (-) and red for positive (+). Similarly, the COVO-S has speaker wire terminals with a black and red color coding. When connecting speaker wire, ensure that the positive terminal on the amplifier is connected to the positive terminal on the COVO-S. And similarly, the negative terminal on the amplifier should be connected to the negative terminal on the COVO-S.
Speaker wires typically use at least one of several possible methods to help maintain correct polarity, including color coded insulation or conductor strands, or printing of text and symbols along one side of the wire insulation.
Amplifier Considerations
The COVO-S’s impedance varies between 6 to 8 Ohms through its frequency range. Care must be taken to ensure that the amplifier is capable of handling a 6-Ohm load. Some amplifiers have a switch that must be set to use with speakers less than 8Ohms. Improper amplifier selection or setup may result in permanent damage to the amplifier or speaker.
The COVO-S can be used with amplifiers between 5 to 100 watts per channel as long as reasonable care is exercised. If there is audible distortion, turn down the volume until the distortion goes away. Never allow the speaker and amplifier to play for more than a few seconds when there is audible distortion.
Removing the Grill
The COVO-S has a removable grill that is held in place by four friction pegs. To remove the grill, carefully pry the grill off from edge until the pegs are fully disengaged. To avoid damaging the speaker drivers, do not touch them either with or without the grill in place.
The COVO-S can be used without the grills installed as long as care is taken to prevent the drivers from damage such as by hard/sharp objects, liquids, pets, or hands. Store the grills in a safe dry place when not in use.

FREQUENTLY ASKED QUESTIONS
Do they fit 5.1 surround satellite speakers well? the front and back?****
Yes, it will perform well.
Can these speakers be wall-mounted?****
They can indeed be mounted on a wall.
How many watts do the speakers use?****
These speakers consume a maximum of 50 watts and an average of 25 watts.
Do these have an amp built in?****
No amp. These lack power and are docile.
Are the speakers 8 ohm?****
6–8 Ohm, 50 W maximum.
Would a turntable be a good fit for these?****
As long as the turntable is connected to a receiver or amplifier with audio outputs, these would work well with a turntable.
Can these be connected to an amplifier using RCA cables?****
No, these have speaker wire binding posts.
Can you use micro female/male plugs to connect them?****
These speakers are passive; therefore, they need an amplifier and a speaker wire connection.
Do these have a back-keyhole mount?****
There is a hole with threads for a screw or bolt to screw into but no keyhole mount.
Are there any volume controls on these speakers?****
No, they don’t; for volume control, they just connect to the amplifier or receiver.
Does this have a remote control?****
No, they are passive speakers and don’t have a remote control.
How long do passive speakers last?****
A good set of passive loudspeakers can last a lifetime, which is one of its many benefits. The technological capabilities of passive loudspeakers are unrestricted, in contrast to many powered and active models of today.
Do passive speakers need a receiver?****
To receive audio from your home theatre equipment (let’s example, a turntable), passive speakers must be connected to a stereo receiver. Passive speakers must always be linked to the receiver through speaker wire; you cannot plug your turntable directly into them.
