Edifier R1855DB Active 2.0 Bluetooth Bookshelf Speakers 70W RMS

Stereo Sound With Connections That Fit Your Home The Edifier R1855DB brings dedicated stereo speakers, built-in amplification and flexible source connections into a compact home audio system. Bluetooth supports everyday wireless listening, while analogue, optical and coaxial inputs accommodate suitable computers, televisions and audio equipment. Its inclined wooden cabinets place the drivers at an upward angle, and a supplied remote makes the system comfortable to use from your seat. A subwoofer output provides an expansion path when your setup calls for more bass. Highlights A Complete Active Stereo System 70W RMS total output from dedicated treble and mid-bass drivers. DSP and dynamic range control in wooden MDF enclosures. Different Sources In One Setup Bluetooth 5.1 plus analogue line, optical and coaxial inputs. Sub Out for a separately purchased compatible powered subwoofer. Considered Everyday Operation 10-degree cabinet incline directs the drivers towards the listener. Remote control with rear-panel tone and volume controls. Key Features Dedicated Drivers With Built-In Amplification The speaker pair combines Nomex-diaphragm mid-bass drivers with 19mm silk-diaphragm tweeters. Its 70W RMS amplification works with digital signal processing and dynamic range control to manage the audio system. This gives you a dedicated stereo arrangement for music, dialogue and everyday entertainment without choosing and wiring a separate external amplifier. A Cabinet Designed Around The Listening Position The wooden MDF enclosures help control cabinet resonance, while a 10-degree incline directs the drivers upwards. That angle is useful for suitable desks and furniture, but thoughtful placement still matters. Arrange the two cabinets around your usual listening position, keep obstructions clear and leave room for the connections at the rear. Wireless Music Alongside Regular Wired Sources Bluetooth 5.1 lets compatible phones, tablets and computers send audio to the active speaker. Analogue line inputs also suit equipment with a line-level output, making the speakers useful beyond a single device. A turntable with only a phono-level output needs a suitable phono preamplifier before it connects to the line input. Digital Inputs For Compatible Television Audio Optical and coaxial connections offer a convenient link to suitable digital audio sources. Use PCM stereo at 44.1kHz or 48kHz, following the manual and the source device settings. The speakers do not decode Dolby or DTS formats. Check the output format before assuming that a connected cable alone establishes compatible audio. An Expansion Route For Low-Frequency Listening A dedicated Sub Out connection supports a compatible powered subwoofer, sold separately. The original speaker pair remains a complete stereo system, so adding a subwoofer is a choice rather than a requirement. Select any additional equipment to suit the room, preferred listening level and source material rather than the power figure alone. Control From Your Seat Or At The Speaker The supplied remote provides everyday source and listening control, with physical controls on the active speaker rear panel for direct adjustment. The active cabinet needs mains power and connects to the passive cabinet by speaker cable. Leave access to those connections when planning the installation, particularly in an enclosed furniture position. Summary Choose the Edifier R1855DB when one stereo pair needs to serve several compatible audio sources. Its built-in amplification, wireless reception, digital inputs and remote control make it a flexible home system, with the option to add a powered subwoofer as your requirements change. Frequently Asked Questions Does the R1855DB include an amplifier?ExpandCollapse Yes. Amplification is built into the active speaker, which links to the passive speaker with the supplied cable. A separate external amplifier is not required. What format should I select for optical TV audio?ExpandCollapse Select PCM stereo at 44.1kHz or 48kHz on the source. The optical and coaxial inputs do not decode Dolby or DTS soundtracks. Can I connect a powered subwoofer?ExpandCollapse Yes. Connect a compatible powered subwoofer to Sub Out. The subwoofer is purchased separately; the two supplied speakers can also be used as a complete stereo system. Are the speakers cable-free when using Bluetooth?ExpandCollapse No. Bluetooth carries source audio to the active speaker. That cabinet still requires mains power, and a speaker cable connects the two cabinets. Are the optical and coaxial cables included?ExpandCollapse An optical cable is included in the manufacturer box list, alongside the analogue audio and speaker cables. A coaxial audio cable is not included. Read more
