Media 4 is Q Acoustics’ first soundbar, which might be the perfect soundbar that gives you the classic sound you have always wanted. Q-Acoustics is well known as a Hi-Fi audio maker and designer based in Britain, and Media-4 is the first model introduced in the US.

We tested its 7000i and 2000i 5.1-speaker bundles and were amazed by the quality of sound produced in a wide variety of audio settings and ranges.

M4 soundbar is a superior dynamic speaker made to provide hi-fi music and top-notch sound from a TV, set-top box, tablet, or smartphone. You can play your music from a phone via Bluetooth or by either using Spotify or Apple Music.

Design of Q Acoustics M-4 Soundbar

Q Acoustics M-4 Soundbar

Media 4 is a solid unit. During the manual physical examination of the soundbar, we found that it is made from high-quality materials, very close to finished matte plastic, and a durable metal speaker mesh combined to produce a loud sound.

In the Q Acoustics M-4’s box, you get all the necessary cables, including an optical one, because optical wires are known for delivering better outputs than their other alternatives. 

You additionally get rubber blocks to be put below the soundbar to reduce vibrations from strong bass, thus,  to keep the sound crisp and clear.

It’s not the most stylish soundbar, but it is also not the smallest one as having a size of 5.6 x 39.4 x 3.6 inches. 

The back end of the soundbar houses two keyhole fixings that enable you to hang the Media 4 on your living room wall. The inputs and outputs are situated on one of the slanting back edges, giving you a small space to connect cables when mounted on the wall. 

We wanted to mount the soundbar on the wall. We were pleased to find out that the holes in the mounting plate enable you to make exact adjustments while attaching it to your walls. After fixing the mounting plate, it had been merely a case of putting the bar on the plate. Then we were good to go. 

Next, connect the power cable and the audio input cable (Analog or Optical). The included analog cable is about two meters long, which is enough in most cases.

The M4’s digital, optical and analog inputs allow a wide range of entertainment sources, including your TV, Sky or Virgin box, CD, DVD or Blu-Ray player, iPhone, smartphone, tablet, convenient music player, PC, or online radio. With Bluetooth availability (utilizing aptX Lossless for sound spilling), the soundbar can practically connect to any Bluetooth sound gadget and remember up to eight pairings. 

The lack of HDMI attachments implies everything that needs to get through your TV using the optical or analog input. Yet there are two analog inputs (RCA and 3.5mm minijack), to connect to an external subwoofer. However, you won’t need one, but it’s nice to choose if you are a bass lover.

Operation of Q Acoustics M-4 Soundbar

Its simple design makes the Media 4 easy to use. The Media 4’s small LED makes things understood – red for off, green and white for analog, and blue for Bluetooth.

The top buttons let you change the volume very precisely, and there’s a remote control included with it. 

Fortunately, the Media 4 can be used with any digital remote that utilizes Philips RC5 codes, such as the Sky handset.

For watching TV and movies, the dialogue is splendidly clear. We were very worried that the shortage of a middle speaker would make dialogue trickier to recognize surround content. We are pleased to mention that this is not the case.

As we mention, the soundbar starts to sound fantastic at volume. At low volumes, the dialogue is distinct, but the music feels lacking. At size, it seems like a correct HiFi setup.

The M4 likewise has a power-saving mode, which is naturally initiated following 20 minutes of inactivity. You are covered if you forgot to turn off the soundbar while it is not being utilized.

Smart Home Integration 

The M4 is enhanced with a smart pre-amplifier and is intended to give louder and clearer sounds from the TV. You can utilize the Optical Out from your TV (2 channel PCM), and the M4 will identify when you need to watch the TV. The only thing you have to do is turn ON your TV.

Performance of Q Acoustics M-4 Soundbar

It’s an excellent set up than the ordinary flatscreen sound, bringing the full-bodied, pleasantly rounded and deep tones that we have expected from the Q’s stereo speakers to a soundbar.

The Media 4 Soundbar utilizes BMR amplifier drive units, and the frequency response range of this soundbar is 20Hz to 20000Hz +-0.5dB. 20Hz means you get the deepest bass that human ears can hear. Although we have seen lower frequency responses, it’s nice to see Q’s commitment to quality industry standards.

We played several music tracks with Media-4 Q Acoustics, from classic style to pop, electronic, and rock, the M4 deals with it wonderfully. 

The sound is so detailed and precise that if you have heard a soundtrack from another set of soundbars, you will notice things that you might not have seen before. 

The sad part is refinement and fineness of the M4 works best only for the music and is limited for the action film sequences.

In our Movie tests, we tested Avatar, Perfume, and Interstellar. All the bass-heavy sounds were delivered with clarity with enough headroom, and the highs were crisp and clear for all the metal clatters and screeches.

It should be noted that its maximum volume could also be insufficient for an oversized room, or the very hard of hearing because it is by no means super powerful and loud.

We have read criticism that there’s no way of adjusting audio delay, but that wasn’t a deal for us. It appeared to be right with no noticeable lag.

The only complaint is the poor remote. It’s tiny (4 cm x 8.5 cm x 0.7 cm), and as a consequence, it could quickly go down the side of the sofa or be thrown out with the newspapers. Some users require more control than directly on/off, volume, source, and mute. This is a definite concern. 

We investigated employing a one for all remote rather than the supplied device. We looked upon OFA’s website for the code, but Q Acoustics’ soundbars weren’t listed. We contacted QA support, and it had been suggested that a Philips code may do the trick. After a touch of twiddling with our OFA (model 7980), We found that system 0641 worked. QA told us that they’re in-tuned with OFA to get their products listed.

Innovative Room Filling Acoustics 

The M4 guarantees that no matter where you are in your room, you will hear all the details, each beat, and make the most of your music to its highest potential. 

This is due to smart, extensive scattering driver innovation and a powerful subwoofer, which not just quickly fills your life with fresh and detailed sound yet, also, gives you powerful controlled bass.

It uses twin 65mm BMR (Balanced Mode Radiator) drive units, the Media 4 gives pinpoint accuracy and overflows with detail straight up to high volume levels. BMR innovation combines the benefits of flat panels and speakers with the goal that the M4 is genuinely compelling and won’t turn harsh when the music or film activity gets too loud. BMR speakers also have spatial imaging – compared with ordinary drive units; they give a comprehensive and extensive sound that comes right out ‘into’ the room.
