Three-band stereo speaker Edifier Studio R2730DB: review and testing

When meeting with photos and characteristics of the models Edifier Studio R2730DB there is a strong sense of deja vu. After all, it is like as two peas to Edifier Studio 7 (R2700), who stayed with us last fall. There are the same diameter and size of the case. And the index clearly says about the changes that will be described.

Edifier Studio R2730DB

The first change is reflected directly in the index of the model. Edifier Studio R2730DB has got built-in receiver Bluetooth, which allows listening to music using the smartphone and tablet without spending time searching for connecting cables. Another significant improvement is the increased power of amplified sections: now each woofer can be bear 40 W (previously 32 W), and supplied to the midrange and tweeter output is reduced by 2 W to 14 W. Also here is a connector for connecting a subwoofer. The remaining advantages remained unchanged.

In terms of size, body materials and finishing the device Edifier Studio R2730DB reminds a model Edifier Studio R2700. Black vinyl film covers the fiberboard panels with thickness up to 18 mm. Appearance is familiar and respectable. The case s qualitative, so there is no sense of fragility. Reliable and resonant structure is a necessary condition for qualitative sound acoustics.

Middle and high frequency speakers are made of cellulose or polymer material. Their light silver color good harmonizes with the black body. Silk dome tweeter with diameter of 3/4 inch is adjacent to the infrared receiver for the remote control (in the active column). Phase inverter is on the front panel, so the speakers can be placed close to the wall (but not too close).

On the right side of the active speaker you can find level controls of high and low frequencies and input selector with LED, informing about the change of color of the currently active input, and a sign to decipher. The control circuit has not changed since Edifier Studio 7 (R2700), except that the added blue LED that lights up when you Bluetooth is connected.

Flanges of all speakers have rubberized adhesive film that prevents parasitic movement of air in the gaps between the housing and speaker. Neodymium magnet system of tweeter has a radiator. Modules of midrange and woofers are stamped and magnet systems are shielded. The base of dome is fabric. Midrange is placed in a separate sealed compartment made of fiberboard. The manufacturer provided foam filling, slightly reducing the effect of "standing waves" in rectangular blocks.
