In the picture the two beauties - Edifier R2700 and R2800. You can see the difference in size for those who already have the experience of listening to R2700 and imagine how much more solid, more thoroughly and fundamentally looks novelty. Bass reflex ports on both models are directed forward, which greatly facilitates the installation of the speakers close to a wall, the external forms and colors correspond to the selected first classical concept. In most cases, a neutral classic design speaker looks appropriate and fits into any interior. 
The cases are made of high quality material, to be exact - from MDF. (medium density fiberboard; Engl MDF - Medium Density Fiberboard.). I must say that the quality of this material may be noticeably different. In order to avoid increasing the cost, many manufacturers use cheap material. Acoustic properties thus markedly deteriorating and MDF boards themselves contain harmful impurities that may lead to poisoning of the human body, especially under the action of vibrations. Some companies have even use of pressed chipboard waste content of harmful substances in which more and acoustic properties worse. They can absorb moisture from ambient air and lose shape deformed. Edifier uses MDF only the highest quality class E0, absolutely do not contain formaldehyde and other toxic substances.

R2800 model front panel reinforced, it is made of MFD of 18.5 mm. This exactly corresponds to the calculations for this particular housing geometry, size and power dynamics. As always - on the principle of necessary sufficiency. Even tapping on the body seems quite muted.

 

column control, volume control, bass and treble tones, the switching signal sources located on the side of the active speaker panel in a recessed niche. Source selection is made by pressing the volume control, as evidenced by the change in color of the indicator light. 


On the back of each speaker Edifier seen stamping and marking model.
