The PB42X is how we take an already great product and make it even better. It is the natural extension of the MB42X’s success – everything we love about the MB42X is there, and now powered. The frontier of affordable high quality sound is pushed ahead even further with the addition of high quality amplification.

Design, Value, Performance
Micca speakers have never been about being cheap, but rather value and performance. This same philosophy guided the design of the amplifier that transforms the MB42X into the PB42X. Using the latest generation class-D chip from Texas Instrument, the PB42X’s amplifier offers a level of performance far superior to existing low cost amplifier products on the market. Its frequency response is smooth and even, along with exceptionally low distortion and noise floor. Together with the included high quality UL-certified 18V/2A power adapter, the PB42X has on tap 15 watts of clean power for each of its two channels.

We won’t repeat all that goes into the MB42X in making it one of the best reviewed small speakers on the market. Suffice to say, everything you love about the MB42X is in the PB42X, from the drivers to the magnetic grill system. The critical 8-element crossover is also completely unchanged, perfectly preserving the voicing of the speaker.

Versatile and Affordable
The PB42X is designed to be simple to use, with both RCA and 3.5mm stereo input jacks. The rear mounted volume control preserves the clean look that customers have come to love about the MB42X. Use it with your computer, TV, or just plug in your smartphone/tablet. The PB42X is the perfect solution for when your space needs a simple and uncluttered speaker setup. Best of all, it doesn’t break the bank and comes at an extremely affordable price.

Try the PB42X risk free in your home with your music. Place them along a wall or near a corner of the room for best results. They can be used on desks, book/wall shelves, or on speaker stands. If you are not absolutely delighted with the PB42X’s performance, simply return them for a refund.

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

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.

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.
