Features

Navis B51 Power Speakers: Designed from the ground up, the full-range, monitor-quality Navis B51 bookshelf speakers feature ELAC concentric-driver technology to deliver unsurpassed mid- and high-frequency performance, coupled with a custom aluminum woofer for truly impressive bass, all in one compact, elegant package. Each of the three transducers is powered by its own dedicated analog amplifier, with a selection of unbalanced RCA or XLR balanced inputs.

Discrete Powerful Amplification: Inside each Navis B51 bookshelf speaker is a Tri-Amp Pure Analog Amplifier, employing three separate amps for each transducer - a 160-watt BASH AB amplifier for the woofer, a 100-watt BASH AB amplifier for the midrange, and a 40-watt Class AB amplifier for the tweeter. A total amplifier power of 300 watts ensures that each speaker is optimally powered, eliminating clipping and crossover distortion, and driving each transducer with authority.

Custom-Designed Drivers: One reason the Navis powered speakers sound so natural is because of its in-house developed transducer, a 4" aluminum midrange driver with a concentrically mounted 1" soft-dome tweeter. Combined, this signature configuration lets Navis set the performance standard for its class. A single woofer reproduces bass with authority, thanks to the special design of its driver. Developed in-house, the 5.25" aluminum cone is the ideal structural material, specified for its ability to deliver punch and accurate low-frequency fundamentals.

Elegant Cabinet Design: The Navis B51 powered speaker's elegant cabinet design integrates perfectly with any interior or decor. Its enclosure has a fine-furniture finish, available in Gloss Black, Gloss White, and Wood Veneer. No grilles are included. A rear-firing flared port on the back of each speaker cabinet provides smooth bass response.

Balanced XLR and Unbalanced RCA Inputs: Connect the variable outputs of your preamplifier or external audio source to either the balanced XLR or unbalanced RCA inputs on each of the powered speakers. There is an input switch on the back of each speaker to indicate an XLR or RCA type connection. Balanced XLR connections guard against induced noise and allow long cable runs without compromising sound quality. There is also an input Gain switch that can be set to High or Low depending on the incoming audio signal.

Optional Wireless Audio Transmitter: The Navis B51 powered speakers feature a built-in wireless receiver that is compatible with ELAC's AirX² wireless audio transmitter (sold separately) which allows you to wirelessly transmit an audio signal from an external source device or preamplifier featuring a line-level output and variable volume control to the speakers.

• Press and hold the "Wireless Pair" button on the Navis B51 speakers until the LED begins to flash rapidly (around 2x per second).
• Press and hold the "Wireless Pair" button on the back of the AirX² wireless transmitter until the wireless pair LED on the Navis B51 speakers stops flashing and goes off (no LED means the speaker is wirelessly paired.)

Optional Discovery Connect: ELAC's Discovery Connect wireless transmitter (sold separately) gives you the ability to wirelessly stream Spotify Connect, Bluetooth, AirPlay and Roon audio content to The ELAC Navis B51 powered bookshelf speakers. ELAC's companion Discovery app (for Apple iOS 9.3+ and Android OS 5.0+) provides setup to your home's WiFi network and control of the Discovery Connect.

• Bluetooth: Bluetooth connectivity means you can easily stream audio from your Bluetooth enabled smartphone, tablet, laptop, or desktop computer to the ELAC Discovery Connect and Navis powered speakers.
• Spotify Connect: The integration of Spotify Connect will enable Spotify Premium users to instantly select and wirelessly stream music to the ELAC Discovery Connect and Navis powered speakers from within the Spotify app (Apple iOS or Android). Subscription & fees will apply.
• AirPlay: Apple AirPlay allows you to wirelessly stream your iTunes music library from your Mac computer, Windows PC or Apple iOS device to the ELAC Discovery Connect and Navis speakers . You also be able to wirelessly stream music apps from your Apple iOS device to the Discovery Connect and Navis speakers. Your Apple iOS device must be running 4.3.3 or better, and your iTunes music software must be running 10.2.2 or better.
• Optional Discovery Music Server w/ Roon & Tidal: When used with ELAC's Discovery Music Server (sold separately), the Discovery Connect acts as a Discovery endpoint and allows connectivity to your networked music collection on your Windows PC or Mac computer using Roon, and gives you access to Tidal (subscription and fees will apply).

Sound Adjustments: The Navis B51 powered speakers provide several adjustments to tailor the sound to your specific environment or taste. Please note these settings should always be set the same on both speakers (except for Right/Left Setting).

• Right/Left: You can designate which speaker will be used at the Right channel and which one will be used as the Left channel.
• 3-Band EQ: The Navis B51 speakers provide a 3-band EQ with Low frequency, Mid frequency, and High frequency adjustment. You can increase or decrease the Low, Mid, and High frequencies to best match your listening content and the room. The Low frequency can be set to +1dB if you like a little more bass or -4dB if the bass is too boomy. The Mid frequency can be set to +1dB to increase detail and vocals or -1dB to offset a room with overly bright acoustics. The High frequency can be set to +1dB to add an extra sense of air and crispness or -1dB to tame harsh sounding rooms.
• High-Pass Filter (HPF): The HPF adjustment allows the addition of a subwoofer to the Navis B51 speaker system through your preamplifier's subwoofer output (the Navis B51 speakers do not feature a sub out). The HPF setting provides a choice cutoff filters (80Hz, 60Hz, or Off) to allow optimum match with your powered subwoofer's capabilities. This setting should be set to "Flat" when no subwoofer is being used.
• Gain: The Gain adjustment allows you to match the input sensitivity of the Navis B51 speaker to the gain of your preamplifier or external variable source. If when setting your volume level you cannot turn the system up loud enough use the "High" setting, if alternatively you find that the speaker is too loud at a moderate volume control setting then use the "Low" setting.

Placement Options: For the best results and the most realistic stereo image and lifelike sound, place the speakers so that an equilateral triangle is created between the speakers and your favorite listening position. This set up creates the optimum imaging performance. If you find that the Navis B51 left and right speakers are too far apart, angle or toe-in the speakers toward the listening position to gain a more focused central image. Place the speakers approximately 1' to 2' away from boundaries such as wall(s) and especially corners. Close proximity to a side or rear wall will enhance bass performance (output), but being too close (particularly to a corner) may result in bass that is unnatural. If a corner location is unavoidable, try to position the loudspeaker so that the distance to the rear wall is not equal to the distance to the side wall.

AC Power: Each powered speaker comes with a detachable 8' AC power cord that will need to be plugged into the back of the speaker and into an AC wall outlet or surge protector (sold separately).
