Three-way stereo speaker system Edifier Studio 7 (R2700): review and testing

Our lab has tested various multimedia acoustics representatives: from compact plastic stereo systems that fit in the palm to very overall and expansive sets of the format 2.1. Sometimes the price is different by far, but it shouldn’t be the only selection criterion: also important are genre preferences, the opportunity to correct placement of speakers in the room and the size of the room.

Edifier Studio 7 (R2700)

Our new guest refers to a rare class of three-way multimedia speaker system. Meet the model Edifier Studio 7 (R2700). In case of proper realization, three-way sound systems can ahead two-way counterparts in the mid-high frequencies, and in terms of lowest frequencies it usually has the advantage. In case of high volume the tweeter of three way speakers is less overloaded due to the increased frequency section.

At the same time this scheme has own characteristics. Due to the presence of midrange speakers acoustic systems are heavier and bigger, while requiring more space for the installation. The speakers are separated in space more than the two-way, so the optimal distance for listening is increased. All these observations are fully applicable to a set of Edifier Studio 7 (R2700) – it is not intended for tiny rooms with area of 8 square meters. We will describe how successful it fulfills the increased size and high price.

Packaging and content

Edifier Studio 7 (R2700)

Quite large package immediately hints that inside you will find an adult speaker system. The front of the box has a depiction of a product and complete wireless remote control, the manufacturer's logo and the model name. Gross weight is about 19 kg, so it is better to transfer the kit together.

The back of the package also has schematics image, the presence of input connectors RCA, tweeters with silk dome and a remote control. Also, there is a photo of the controls, the models with connectors, cables for connection of passive speakers and remote control. There are detailed specifications listed in the table above the specification.

The top of the box provides the images of accessories of Edifier Studio 7 (R2700).

It is good that the manufacturer did not skimp on the cables. In addition to paper warranty card and manual, we found the remote control, cables 2 RCA ↔ 2 RCA, 3,5-mm jack ↔ 2 RCA, detachable power cord, and even packed in separate plastic blister optical S/PDIF. Note that it is not specified in the list on the box.

Design and structure

Speakers Edifier Studio 7 (R2700) with grills look strictly and soundly. Black vinyl film only reinforces this feeling. Such sized system cannot be called a desktop. Therefore, before purchasing it is necessary to make sure that it has a free space in the room.

Edifier Studio 7 (R2700)

After removing the grills, we can see large speakers for multimedia speakers. The flanges of each are recessed. But now we do not pay attention to them, and case thickness. According to the manufacturer, the thickness of the used fiber-boards is up to 18 mm. This is a very important parameter, which says that the company tried not to skimp on the body, because in case of weak walls you will have housing resonances and sound will acquire an unpleasant hum. In this case this it is impossible. Now let’s proceed for the speakers.

Diffuser of woofer with diameter of 6.5 inches is made of paper or similar material of light silver color and is added by black a rigid dust-protective cap. Concentric circles probably should increase its rigidity. According to our measurements, the effective diameter of the diffuser is 120 mm or 145 mm with suspension. Woofer provides frequencies from 50 Hz to about 200 Hz, where four-inch midrange speaker which picks up the baton.

Edifier Studio 7 (R2700)

Its design and materials are identical to the low-level item. Here we only note that its presence should will provide better transmission of voice frequencies and reduce the burden on Tweeter at high volume. It plays about 2800 Hz. Even higher the role comes to dome tweeter with section of ¾”.

Edifier Studio 7 (R2700)

Edifier says its dome is made of silk. The choice of this material does not automatically mean that tweeter will get better sound: many expensive counterparts are made of synthetic materials, but silk options are also available. Although most exotic material of tweeter was a diamond.

A large port of phase inverter in model Edifier Studio 7 (R2700) is neatly displayed on the front panel and is protected by fabric mesh against foreign objects. Front-location of phase inverter allows to move the speakers closer to the wall without causing unwanted hum and improves the sound of acoustics in small rooms.

The front face of the active speaker has IR receiver of remote control. The right side of the body has level controls of low and high frequencies, as well as a digital volume control combined with the input selector. Under it is the LED, which indicates by the color change about the currently active input and label for decryption.

The rear panel of the active speaker has the panel connectors, including two analog stereo-RCA, optical and coaxial S/PDIF inputs. Above the plug for the power cord there is a power toggle and a reminder that the maximum power consumption does not exceed 150 W. Fixed cable to connect to the passive speaker has a large cross section and poor flexibility. It ends with angular DIN connector with metal housing.

At the base of the speaker are legs of a soft porous rubberized material height of about 5 mm.

At the opening of the active speaker note the presence of internal filler and insulation mid-level in a separate compartment.

Protective fabric mesh is fixed to the chassis of the fiberboard. It is easy to bend, so provides decorative function than protective one.
