Minirig 4 (vs 3) Review
More features same sound?
Minirig 4 Overview
Firmware Tested: 14
Minirig is a company started by audio enthusiast David Trotter back in 2011 and is a UK based company.
While the first Minirig was a wired speaker subsequent versions since the MK1 have been both bluetooth and wired. As you would hope with a speaker built from the ground up by an enthusiast the auxiliary inputs and outputs are high quality and offer near zero lag. Certainly below the 16ms resolution of my own testing. Now in its 4th iteration the Minirig MK4 brings many new features. The Minirig is a 360 degree speaker when laid flat on its backside but can also be used in on-axis mode directly facing you. Let’s lay out what’s changed and what hasn’t changed.
Things that are still the same from the MK3 version:
Battery 28.9Wh
Bluetooth 5
Still does TWS and multi link-up (however TWS now requires both speakers to be turned on within 5 seconds of each other in wireless mode)
60hz-18khz rated
70mm driver
Thats thats are now different:
Mk3: 2x auxiliary connections both input/output
MK4: 2x auxiliary connections now top is input and bottom is output
MK3: barrel charger 7.5 watts
MK4: USB-C up to 30 watts two way
MK3: Aptx, SBC
MK4: AAC, SBC
MK3: high gain, low gain modes
MK4: one gain mode
MK3: one protruded LED button for all functions
MK4: 4 flush leds for volume and power info, 3 recessed buttons for power, volume up and down, Bluetooth/connection indication
MK3: max battery life was 7 hrs
MK4: max battery life now 5 hrs
MK3: Charge time was about 4.5hrs
MK4: Charge time now 1.5hrs with 30 watts PD
MK3: manual eq only, 5 band equaliser in app
MK4: Accelerometer detects orientation to adjust treble, 2 band equaliser in app
MK3: no phone calls
MK4: can be used for phone calls
MK3: 40 watts
MK4: 50 watts
MK3: separate app for updates
MK4: update via one app
MK3: subwoofer volume control via app
MK4: no separate subwoofer control
MK3: 545g
MK4: 560g
MK3: pause for multipoint
MK4: straight multipoint
Frequency Response
This shows the differences between my own Minirig 4 and Minirig 3. Due to speaker unit variability and how close the differences are your experience in how they differ audibly may be different.
The Minirig 4 overall shares the same sound signature as the Minirig 3 and I would describe that as on the bright side of neutral with a punchy but not extended bass. Being a 360 degree speaker how you listen to the Minirig will totally change your perception of its overall character. More V-shaped at low volumes to adjust for dynamics in terms of our perception of sound at lower volumes. Bass rolling off as you pass 60% volume. Turning on tilt eq will reduce treble when placed on-axis or so called studio mode.
In terms of changes vs 3 I note slightly less bass and slightly more high end. I do not know if this is just speaker variation or how it has been tuned. The Minirig 4 ultimately goes louder than my Minirig 3 but with a tad less bass while doing so than the MK3.
Minirig 4 – Sound!
You will need good ears to hear the differences between the MK3 and the MK4 based on my units. Although in an A/B the differences are there I would imagine playing only one at a time the overall character will be pretty simialr. For me the sound is on the more clinical/bright side. It certainly is a highly resolving speaker and will suit those favouring clarity over bass. It is also a speaker often spoken of as very neutral. I’m not sure I would agree with this but as is often the case a slightly bass lacking speaker with a clear high end and good mids is said to be neutral. for me personally the Minirig when played as a single unit lacks bass weight and extension. I understand this is tuned for the more discerning ear and minimising audible distortion is favoured over pushing more bass via DSP. Due to the design of the speaker as a single driver upwards or side on firing, how you listen to this speaker can totally change how it sounds. I judge the speaker l;sietnign 45 degrees above and down on the unit and straight on its side in so called studio mode. The Minirig is certainly a speaker I think of as suited to more near field intimate listening than outdoor parties but it can get pretty loud so can do both. However going loud as a single unit means a complete lack of bass.
The Minirig 4 can get pretty loud. Hitting around 106 dB(C) @1m peak when playing Onlap – Rock Ain’t Dead at 100% volume. There is little bass at these volumes however.
Options are game changing!
I have talked of the Minirig 4 as a single unit only. However when you buy into the Minirig system its all about its modular nature. You can hook up multiple minirigs in both bluetooth mode and wired mode. When you do so everything changes. When I pair two Minirig 4s in TWS the whole sound comes alive. It does so the classic way of sum of whole being greater than the sum of the parts. Imaging and soundstage are fantastic and it offers both immersive and fun analytical listening. It does sound punchy rather than warm and warm is my preferred signature. However it is still a great listen and is game changing. For me a single unit is a bit on the bland side for listening and mono is not something I enjoy anyways. But two units in TWS makes the money I spent on them worth it. TWS is now pretty solid (albeit they must be turned on within 5 seconds of each other) whereas it was often unusable on the Minirig 3.
Then we have the subwoofer option (wired only) which adds a huge push for the low end. Even the subwoofer though is more punchy than extended but does again elevate the whole listening experience to a different level. We also have the Minirig Mini which can be paired with all other units (wired with Minirig 4). So the Minirig must be thought of as an ecosystem rather than judged simply on a single unit.
Conclusion
For new buyers the Minirig MK4 is a good option if you intended at some point to buy another Minirig whether it’s the subwoofer or another MK4. At £150 it is a harder decision for those that already have the MK3. USB-C connection and better TWS pairing may be enough to make the choice. In terms of sound differences it could be same, better or worse depending on speaker variation due to how close they sound to each other anyway.
