Micca ON3 Powered Bookshelf Speakers
The Micca ON3 is a great looking and sounding pair of powered bookshelf speakers that can be used in any room in your home or office. Its compact size makes it suitable for use with your computer or TV, or for playing music from a smartphone in the kitchen. Equipped with front and rear input jacks and a convenient remote control, the ON3 is both versatile and easy to use. Its full and rich sound signature is a good match for all music types, from modern pop songs to classic vinyl records.
More Than Skin Deep
Speakers are not invisible, so the ON3 is designed to look good with its clean classic lines, warm walnut pattern finish, and rich grill fabric. The ON3 looks good anywhere. The front grill is removable, with a magnetic attachment system that does not leave unsightly holes when removed. Take the grill off for a bold look, or leave them on for a more classic appearance and to protect the driver from small hands and curious pets.
Below its attractive exterior, the ON3 is packed with technology. Its 3 inch full range driver uses lightweight fibrous paper cone, rubber surround, and a neodymium magnet structure. The combination of 1-inch voice coil, raised-dome center cap, and a copper shorting ring reduces distortion and improves efficiency at high frequencies. The result is a driver that is capable of output to the limit of human hearing at 20kHz, without the typical harmonic, intermodulation, and cone breakup distortion that is common with other full range drivers. Carefully engineered driver suspension characteristics together with matched enclosure port tuning allows the ON3 to provide in-room bass output down to 50Hz. Driven by a 24-Watt x 2 stereo amplifier with DSP tone shaping and dual EQ profiles, the sound signature of the ON3 is surprisingly full and well extended for a speaker of such compact dimensions.
Single Driver Design
Using a single driver in a speaker design has the benefit of being naturally coherent, eliminating the problem of acoustic lobing, time alignment, as well as potential phase problems caused by crossover circuits. The result is that music sounds more natural and true to life
Advanced Amplifier
The ON3 has a 24W x 2 amplifier built in, with front and rear input jacks to allow connection with any analog audio source. The amplifier is enhanced with DSP processing circuitry that works together with the driver and ported enclosure to deliver rich and full sound from 50Hz to 20kHz.
Remote Control
A convenient IR remote control is included that allows quick setting of volume, mute/unmute, and selecting between two EQ profiles. The remote control can be stored neatly on the side of the speaker. The volume knob on the speaker provides full controls in case the remote is misplaced.
Owing to its handsome and classic good looks, the ON3 is especially suitable for use with a record player. Built-in linear-phase high pass filtering safely rolls off frequencies below 30Hz for effective rumble control. Note that the record player must have a built-in phono amp, or an external phono amp (not included) must be used. Use EQ profile 1 for a flat frequency response that brings out musical details, or use EQ profile 2 for a more laid back and classic sound signature where the bass is slightly enhanced and the treble is lowered a touch.

Why is the impedance 4-8 Ohms? Will it work with my receiver?
Micca is one of the few manufacturers that specifies the impedance of its speakers as a range, rather than a fixed nominal value. The impedance of a speaker varies depending on the frequency being played, and it is normal for most 8ohm rated speakers have impedance that dip as low as 4ohms or even lower.
While the Micca speakers work just fine with most amplifiers and receivers rated for speakers designed to handle 6ohm or 8ohm speakers, the 4-8ohm rating is a reminder to users that these speakers do have impedance that go down to as low as 4ohms and care should be taken with the listening volume so as not to damage the amplifier or speakers. Please observe the following precautions:
- Do not play the speakers at a volume where there is audible distortion
- If the amplifier’s output protection is triggered, immediately discontinue use
- Ensure that the amplifier has plenty of ventilation and is not in an enclosed space
- If the amplifier has a “4Ohm” or “High Current” mode, enable it

Different versions of Micca MB42X and MB42X-C: Original, MKII, MKIII
At Micca, we continuously look for ways to improve our products for better performance, quality, and value. Since introduction, MB42X and MB42X-C speakers have undergone evolutionary updates as described below:
Original Release – Based on MB42, with the following differences
- 8-element 12dB/Octave crossover upgrade
- Matte black vinyl
- Magnetic grill system.
MKII – Serial numbers start with “MB42XMKII” or “MB42XCMKII”.
- Slight adjustments to woofer and tweeter response characteristics
- Flared plastic port tube (MB42X only)
- Additional internal bracing at four side enclosure walls
- Poly fill stuffing added
MKIII – Serial numbers start with “MB42X3” or “MB42XC3”
- 9-element 18dB/Octave crossover
- Tighter driver response tolerance
MKIII crossovers are backwards compatible with all previous versions and provides the following benefits:
- Steeper slopes for reduced distortion and acoustic lobing
- Adjusted roll off frequency for improved phase integration
- Updated driver level matching to result in overall smoother response

Micca MS10/MS12 Subwoofer No Sound
There have been a small number of Micca MS10 and MS12 subwoofers that does not play sound when received by the customer. The symptom is that the subwoofer turns on, the power light turns blue, but there is no sound. The cause of this is that an internal subwoofer connector has come loose during shipping and need to be plugged back in. If your subwoofer has this behavior, please follow the steps below to check if it applies to you. Please read the instructions carefully and if you are not comfortable doing any of the steps, please contact our support and we will exchange the subwoofer for you. The steps here are to save you the trouble of boxing up the subwoofer and returning it.
Step 1: Remove all audio connections.
Step 2: Use a philips screw driver, remove the 12 screws along the border of the metal amplifier plate on the back of the subwoofer.
Step 3: Tilt the amplifier out and check if the connector at the circled location below has come loose. Reconnect the connector if necessary. Note that the red wire is to the left, and black wire to the right
Step 4: Reinstall the plate amplifier, hand tighten all 12 screws along the border of the metal amplifier plate.
Step 5: Reconnect audio connections, and plug the subwoofer back into AC power. The subwoofer should now be working correctly. If you continue to experience issues, please contact email support@miccatron.com and we will provide additional assistance.

Micca MB42 vs MB42X, What’s the difference?
When it comes to the MB42 vs MB42X decision, it’s important to understand the similarities and differences between these two speakers. We hope this guide is helpful in making the right purchase choice.
Similarties
The MB42 and MB42X uses the same drivers, consisting of a 4-inch carbon fiber woofer, and 0.75-inch silk dome tweeter. Both use the same size enclosure and the same tuning frequency. With their grills on, it is difficult to tell them apart visually from a few feet away.
Differences
Even though the MB42 and MB42X share the same drivers and enclosure design, the MB42X represents a sizable upgrade in terms of audio performance. The most significant improvement offered by the MB42X over the MB42 is the inclusion of a 9-element crossover network. This crossover significantly improves the tonal balance and clarity of the speaker and is what’s responsible for the MB42X being such a favorite among hi-fi enthusiasts. There are also other improvements included in the MB42X, such as a flared port tube and a magnetic grill system. Lastly there is the cosmetic difference of a matte black finish on the MB42X, versus the black faux wood grain on the MB42.
The table below contains the differences between the MB42 and MB42X.
| MB42 | MB42X | |
| Woofer | 4-Inch Fiber Woofer | 4-Inch Fiber Woofer |
| Tweeter | 0.75-Inch Silk Dome | 0.75-Inch Silk Dome |
| Crossover | None, protective capacitor on tweeter | Advanced 9-element crossover, 18dB/Octave woofer and tweeter |
| Enclosure material | MDF | MDF |
| Enclosure Finish | Black faux wood grain vinyl | Matte black vinyl |
| Tuned Port | Cardboard tube | Plastic tube, external flare |
| Protective Grill | Cloth, peg mount | Cloth, magnetic mount |
