Best Passive Soundbar To Complement Your Audio Setup In 2018

There are two types of speakers – Active and passive. Active speakers are those that come with built-in amplifiers. They are also known as powered speakers and can be directly connected to a mixing board. Passive speakers, also known as non-powered home theater receivers, are traditional speakers that need external amplifiers or AV receivers. They lack digital signal processing and inputs. But passive speakers have a lot of flexibility. You can select your own amplifier and receiver, decode a large number of audio formats, connect more number and type of sources and experiment with various subwoofer and soundbar settings.

We tested and short-listed few quality passive soundbars. These products can complement your home theater systems and active speaker setup. Check the below list to know more.

The Best Of The Best Passive Soundbar List For 2018 :

Definitive Technology Mythos SSA-50 Passive Soundbar :

Definitive Technology Mythos SSA-50 passive soundbar is a 5 channel 3D surround sound non-powered home theater receiver. The 3 front channels – left, right and center – include tweeters that are positioned in front of the corresponding drivers. Definitive Technology has named this specially engineered tweeter-midrange driver alignment ‘Axially Aligned’. This arrangement helps project high precision sound to make it more exact and life-like. The Mythos SSA-50 is equipped with Spatial Array technology which enhances the 5 channels to produce room-filling surround sound. This advanced technology focuses sound on specific positions for better spatial presentation of the 5 channels. This produces the illusion of sound coming from five different speakers placed in different parts of a room. Spatial Array technology does not require sound from the soundbar to be reflected off of walls to create theater-like sound. This means you can use the Mythos SSA-50 in any room irrespective of its size, shape or layout. The soundbar also comes with Balanced Dual Surround System (BDSS) technology which provides double support or surround points to the speaker cones. BDSS drivers promote precise frequency response and linear cone motion by suppressing cone resonance. The Mythos SSA-50 is made of aircraft-grade aluminum. It has damping technology which improves surround sound effect. The soundbar is fitted with pure aluminum ceramic-coated dome tweeters for smooth and unmatched detailed sound.

Klipsch Gallery G-42 Passive Soundbar :

The Klipsch Gallery G-42 is a one-piece cross-over 5.1 channel home theater speaker system. It is a passive soundbar that functions as a receiver as it does not have internal receivers. This is a big advantage because it means you won’t have to buy a separate receiver. Also, built-in amplifiers that soundbars generally come with aren’t very powerful. Therefore, the Klipsch Gallery G-42 does away with them completely. Instead it uses advanced horn-loaded speaker technology to produce stunningly clear sound and sound effects. The soundbar has 3 Tractrix horns with 1 inch titanium dome tweeters. This produces superior audio that emphasizes on depth and detail of vocals and dialogues. The design of the tweeters is specially engineered to project more volume per watt than the standard flush-mounted dome tweeters. The flared horn keeps ceiling and floor distortions in check and makes sound more realistic by projecting the sound beams with greater precision and sharper imaging. The dynamic 1 inch tweeters are designed for left, right and centre channels.
