Edifier S351DB Bluetooth Bookshelf Speakers with Subwoofer 150W RMS

Stereo Detail With A Dedicated Foundation For Bass The Edifier S351DB brings two bookshelf satellite speakers and a dedicated subwoofer together as one active 2.1 system. Its separate treble, mid-bass and bass amplification supports music, films and games without requiring an external amplifier. Bluetooth handles compatible wireless sources, while analogue, optical and coaxial inputs accommodate suitable computers and home entertainment equipment. Wooden cabinets and direct speaker controls give the setup a composed, practical character, with a remote for adjustments from your usual listening position. Highlights A Complete Active 2.1 System 150W RMS total output across two satellites and the supplied subwoofer. Dedicated treble, mid-bass and bass amplification with DSP and DRC. Drivers For The Full Arrangement Titanium-dome tweeters and aluminium-diaphragm satellite mid-bass drivers. An 8-inch long-throw subwoofer with a calibrated bass-reflex port. Flexible Everyday Connections Bluetooth with Qualcomm aptX from a compatible source. PC/AUX analogue inputs, optical and coaxial digital inputs, plus remote control. Key Features Two Satellites And A Purpose-Built Bass Cabinet The supplied subwoofer takes responsibility for low frequencies while the two satellites establish the stereo image. Its 8-inch driver is supported by a dedicated 70W RMS amplifier, with a published subwoofer response of 40Hz–160Hz. This gives the system a defined bass component for music and screen entertainment, rather than asking compact satellite cabinets to reproduce the entire range alone. Separate Drivers For Treble And Mid-Bass Each satellite combines a ¾-inch titanium-dome tweeter with a 3.5-inch aluminium-diaphragm mid-bass driver. Their separate amplification works within a Class-D system using digital signal processing and dynamic range control. In practical terms, the driver arrangement divides the work across different frequency ranges. Place the left and right satellites with the listening position in mind so the stereo layout remains useful. Wooden Cabinets And Deliberate Placement The wooden speaker enclosures help manage unwanted cabinet resonance, while the subwoofer uses a calibrated flared bass-reflex port. The satellites can be positioned around a display or listening space, with the bass cabinet placed where its size and connections can be accommodated. Keep ventilation openings clear and allow at least 5cm around the equipment, following the manual. The published net system weight is separate from the weight of a shipping parcel. Digital Audio From A Compatible Screen Source Optical and coaxial inputs receive PCM stereo at 44.1kHz or 48kHz. For a television, set the audio output to a supported PCM format rather than a surround bitstream. A compatible optical or coaxial output is required; HDMI ARC and USB audio are not listed inputs on this system. Check the available connection and source settings before choosing a cable or assuming a console connects directly. Wireless Listening Alongside Analogue Sources Bluetooth makes it convenient to play from a compatible phone, tablet or computer, with Qualcomm aptX available when the transmitting device supports it. PC and AUX provide analogue line-level alternatives for equipment with a suitable output. The input labelled PC is an analogue connection, not a USB sound card. A turntable that supplies only phono-level audio needs a suitable phono preamplifier before it connects. Useful Control Without A Separate Receiver The active satellite provides direct input, listening-level and tone adjustment, with a display indicating the selected source. The supplied infrared remote adds input selection, volume, mute and standby control from your seat. Bluetooth playback controls operate in the applicable wireless mode. Speaker cables still connect the cabinets, and the system needs mains power; Bluetooth removes the source audio cable rather than every cable in the setup. Summary Choose the Edifier S351DB when you want the separation of bookshelf speakers and the presence of a supplied subwoofer in a single active system. Its wired and wireless input choices make it suitable for a considered desktop or home entertainment arrangement. Plan the space for all three cabinets and confirm a compatible source output, especially when using digital television audio. Frequently Asked Questions Is the subwoofer included with the S351DB?ExpandCollapse Yes. The system includes two satellite speakers and a dedicated 8-inch subwoofer, with amplification built into the supplied system. A separate external amplifier is not required. What audio format should I select on my TV?ExpandCollapse For optical or coaxial audio, select PCM stereo at 44.1kHz or 48kHz. The manual specifies PCM decoding on these inputs. Check that your television or source has a compatible output. Does the PC input connect by USB?ExpandCollapse No. PC and AUX are analogue line-level inputs. The listed source connections are PC, AUX, optical, coaxial and Bluetooth; USB audio and HDMI ARC are not provided. Do I need an aptX-compatible phone for Bluetooth?ExpandCollapse A compatible transmitter is required to use the Qualcomm aptX codec. Bluetooth compatibility and available playback functions depend on the source device and its software; the speakers can also use their wired inputs. Are the three speaker cabinets connected wirelessly?ExpandCollapse No. Speaker cables connect the satellites and subwoofer, and mains power is required. Bluetooth provides a wireless audio connection from a compatible source to the system. 続きを読む
