This Resonance Box is dedicated to the Muro Box-N40 model.

It was designed to enrich the details of the sustaining sound effect of Muro Box N40, not just to amplify its volume, because the current volume of Muro Box N40 is loud enough for regular home settings.

Explore the sustain effects of different resonance boxes and find your favorite. Then, choose the resonance box design that best matches the color of your Muro Box N40.

Listen to the N40 Sublime Model Music Box With the Performance Effects of Different Material Resonance Boxes!

Millettia Laurentii (Chicken Wing Wood) is a harder wood option, while Pinewood is a softer wood option. From the video, you can hear that the Millettia Laurentii resonance box produces a brighter and clearer sustain, while the Pinewood resonance box creates a rounder, fuller resonance.

We selected the classic piece “The Old Clock” to help you compare the sound quality differences using a familiar melody. The recording was done in the same setup environment with various combinations of different models and resonance boxes, allowing you to directly compare and find your favorite sound combination!

Pinewood

Pinewood has a clean white color, which turns slightly yellow after applying transparent protective varnish. Pinewood is easy to process, the material is readily available, the wood grain is clean, and the color variation is stable. Due to its low hardness, the residual echoes are noticeable. However, traditional music boxes emphasize the vibrational sensation of the bass side’s aftertaste, and the more pronounced residual echo is exactly the characteristic sound when used as a traditional music box.

The unfinished Pinewood resonance box is the default version provided with the purchase of the N40 music box, unless you have upgraded to the Pinewood resonance box with clear lacquer finish or the Pinewood resonance box with black walnut lacquer finish, or selected the Millettia Laurentii (Chicken Wing Wood) resonance box for your N40 music box shipment. In those cases, we will ship the N40 with the selected resonance box as per your instructions.

Which Color of the Pinewood Resonance Box Do You Prefer?

Taiwanese Acacia wood

Taiwanese Acacia wood is a deep coffee color, and due to additional heat treatment, it has the highest hardness of all the woods mentioned. The high notes are solid and clear with each note, but they don’t feel as dry or dull as maple. Instead, they have a pleasant, proper aftertaste.

More importantly, it has a unique caramel aroma, allowing you to almost “smell the taste of music” when you’re close to it. Each Acacia wood resonance box is hand-waxed, avoiding spray painting in order to preserve the unique caramel scent created by the heat treatment.

Millettia Laurentii

Millettia Laurentii (its Chinese name means “Chicken wing wood”), as its name suggests, features the most pleasing deep black feather-like wood grain. The sound leans towards cleanliness, but it’s slightly more complex than acacia wood, with additional characteristics reminiscent of the wings of chickens.
The residual echoes in the bass are more pronounced, but it doesn’t feel sticky together like pinewood. Apart from the wood itself lacking any noticeable odor, the sound quality is top-notch. I consider it a reliable choice of wood. However, there is one drawback to the appearance of chicken wing wood: the prominent fibrous texture and occasional small pieces of wood may chip off at the edges.
Please note that this flaw is inherent to the material and unavoidable; we will ship it out as standard quality products.

Summary of Insights from Experimenting with Various Resonance Boxes

Here is the evaluation from Muro Box inventor Dr. Chen-Hsiang Feng, comparing the wood characteristics of various resonance boxes based on sound quality and appearance after actual prototyping:

Considering both sound and appearance, Millettia Laurentii > Pinewood. This ranking also corresponds to the order of hardness of the woods themselves. Music boxes are indeed more suitable for resonance boxes made of hardwood.

N40 Resonance Box Assembly Steps

1. Use your fingers or a screwdriver to remove the 8 hand-twist screws.

2. Screw the 4 shock absorbers into the 4 corners’ holes under the resonance box. Place the 4 shock absorbers above their pads to prevent the shock absorber scratching the table surface.

(3) Next, place the sound post. Its primary function is to support the weight of the music box on the top board, while also enhancing sound transmission.

First, adjust the sound post to the appropriate length, then check the length against the edge of the resonance box.

The goal is for the sound post to “just” protrude slightly above the resonance box to touch the top board. As long as there is slight contact, it will be effective. Do not extend it too much, as this could cause the top board to crack. Please be careful to control the protrusion to be less than 1mm.

(4) The position of the sound post can be placed according to your preference. Place the top board on the resonance box to feel the contact position of the sound post, or confirm the placement of the sound post from the side lifting holes. Then, screw the hand-twisted screws to fasten the top board on the resonance box. Be sure to tighten the hand-twisted screws to avoid noise during music box playback caused by vibration.

(5) We’ve left a little fun for you. In addition to placing the sound post in the middle, you can try placing it in other positions to hear the sound effect. Once you find your favorite position, remember to ensure that the hand-twisted screws on the top board are tightened when experimenting with the sound effect.

(6) The C-shaped sound hole on the top board of the resonance box is designed based on the principle of violin sound production. The curved square groove of the Muro Box Logo is for securing the bottom feet of a 20-note Muro Box music box, while the four small circular grooves are for fitting the 4 feet of the N40 music box. The two types of grooves allow customers who own both a N20 model and a N40 model of music boxes to interchangeably use this same resonance box for amplified playback effects.

(7) Place the four feet of your N40 music box on the four small circles on the music box, plug in the power, and you will hear the default music box melody (a jingle) when the music box is turned on. You can press the knob on the front side to play the preset music box melody, or start pairing it with your Muro Box App to experience the thousands of melodies in our online music library.

You might be curious as to why only two of the four bottom feet of the N40 music box have these soft pads, instead of all four being installed.

The reason is that we need to ensure that two of the wooden feet make direct contact with the resonance box to achieve the best sound transmission effect. Therefore, only two of the bottom feet are equipped with shock-absorbing pads.
