Edifier R2750DB Speaker type 2.0, 3.5mm to RCA/Bluetooth/Optical/Coaxial, Bluetooth version 4.0, Black, 136 W

R2750DB speakers These speakers boast 136 watts of power, which is very rare for speakers of similar size. The three-way Tri-Amp amplifier allows you to indulge in sounds that are both clear and powerful. Both speakers are enclosed in wooden MDF panels to minimize any possible echo, so with them you will get a whole new music experience, rediscovering your favorite songs in even better quality.     Multi-purpose With Edifier's R2750DB speakers, almost any device is compatible. Pair your smartphone via Bluetooth and leave the cables behind. Or connect your TV or gaming system via coaxial, optical or RCA connections. Digital input The coaxial connection is not as common as optical, but if your device has it, the coaxial connection tends to sound better due to its wider bandwidth, meaning it can handle higher quality audio up to 24-bit192kHz. Optical is typically limited to 96 kHz.   Bluetooth wireless connection Stream your music wirelessly to the R2750DB using Bluetooth v4.1 technology. Connect your laptop, tablet or phone via Bluetooth and get the party started with your playlist.   Remote controlled The R2750DB features an ergonomic remote control that allows you to change source, volume, Bluetooth, track selection in Bluetooth mode and a handy mute button. Take control of the sound without leaving your chair.     Fine adjustment On the side panel you'll find the treble and bass adjustment knobs you need to set your speakers exactly how you want them and, in addition, you'll find a calibrated reflect bass port on the front of the cabinet. A class-D amplifier system with digital signal processing and electronic tone control technology will give you an extra musical experience.   Additional power Use the F5 pin bi-amplifying XLR type speaker cable with angled plugs for connection. The R2750DB speakers are equipped with an additional output for an independent subwoofer, which you can plug in at any time and turn your 2.0 set into a 2.1, thereby boosting each of the bass emitted.   Specification   Total power 136 Watts Output power RMS 14W x2 (tweeters) + 14W x2 (midrange speakers) + 40W x 2 (woofers) [DRC ON] Signal-to-noise ratio (SNR) ≥85 dBA Frequency response 45Hz-20KHz Audio input AUX, Bluetooth, Optical, Coaxial Controls The remote control and handy knobs on the side panel allow you to fully adjust the parameters Bass speaker 6.5 in (178 mm) Midrange speaker 4 inches (116 mm) Treble speaker 34 inch NDFeB Weight approx. 20kg Dimensions: 218mm x 393mm x298mm (WxHxD)
