A Popular Bookshelf Speaker with Mark Audio 4 Inches Full Range Unit

A popular Bookshelf Speaker with Mark Audio 4 Inches Full Range Unit 

As you know, the greater the material density of the speaker enclosure, the less the vibration produced by the enclosure. Solid wood is more reflective of sound than other materials, and tightness of the wood is higher, and the sound can be effectively expressed by the vibration of the air inside the box. We often say that the sound of wooden speakers is warm, in fact, the word warm means the balance of tri-band that are low, medium and high frequency; if the frequency is too low or too high, it will make people feel uncomfortable. The advantage of wooden speaker is that its playback effect is good, the vibration of the sound inside the box is stable, and the sound effect will be balanced and full.

Here, we made a pair of bookshelf speaker with solid wood, and matched with mark audio 4 inches full range units. This enclosure is designed for the unit, its volume is about 7.6L, and you may place them into your bookshelf, or place on the stands as the photos showed below, thank the audiophiles share the photos and comment below.

"Like a bookshelf speaker, it is the size that can be put in an actual bookshelf. The amount of bass is just right, so the sound doesn't get muffled even if you put it like that. Works great with MarkAudio speaker units."

And comment it, "The feeling of hand-made natural wood is very good. The sound is great too."

Here, we offer the empty cabinet and full range speaker unit for DIY if you like.
