BOSS Dual Cube LX Review

It’s the Dual Cube LX in its guitarist version that we’re unlocking today. It is a small 10 watt speaker with two 4 inch speakers providing 5 watts each. The chassis is made of plastic that inspires confidence, as in the Cube series. We’re also surprised by the 3.3kg featherweight and dimensions of 341mm x 162mm x 215mm making this speaker easy to transport or place on the corner of a desk for work. It will be possible to operate the Dual Cube LX using the included block or with 8 LR6 batteries. Of course, we can’t help but see it as a direct competitor to the Yamaha THR10II, we’ll come back to that point later in this test.

In terms of functionality, the Dual Cube LX is fairly well equipped with two inputs that allow you to connect a guitar, but also a multi effect that turns the amplifier into a FRFR amplifier, microphone or even a potential keyboard. Of course, you can also connect headphones in the 3.5 mm jack format. Cube series regulators, myself included, would be out of place to find a potentiometer that allows them to cycle through 7 amplifier simulations from the clearest to the most saturated. There is also a “MIC” mode and a “STEREO IN” line mode.

The suggested simulation is as follows:

  • audio sim
  • JC Clean = Roland JC-120
  • US Combo = Echo Fender Deluxe
  • Brit Combo = Vox AC-30TB
  • Hi Stacked = Marshall 1959
  • Metal Stack = Peavy EVH5150
  • Max = Channel 2 Modern Mode for Dual MESA/Boogie Rate

We find classic and basic potentiometers for gain, volume, bass, midrange, treble, and mr. ComingSignal Add two potentiometers to adjust the combined effects including: Chorus, Flanger, Bridge, Vibration, Heavy Octave, Delay and Reverb. There is also a tap rhythm button. It is possible to save the setting quite easily by holding down the “Memory” button. This provides three memories for each simulation. After that, you can call up the presets either using this same button, or by connecting a foot switch of the type Boss FS-5U or FS-7, unfortunately it is not provided.

The Dual Cube LX also has a looper for recording up to 90 seconds of music, which is great. However, this can only be controlled with a second foot switch, and is not supplied. This is even more annoying, because it is impossible to use it in another way. There are no buttons on the main board to start recording as on other Cube series models. It will be necessary to pay an additional fifty euros if you want to have a brand switch. Likewise, this speaker has a non-functional Bluetooth connection out of the box. Again, you will have to buy the brand’s “BT-Dual Bluetooth” adapter, always for an additional fifty euros. If brands always, for the most part, sell their foot switches separately from less expensive amplifiers, not allowing certain key features of a device to be used without these switches is an unfortunate practice. Especially since in 2022, while some coffee machines have an automatically integrated Bluetooth / Wifi connection, it’s surprising that Boss simply didn’t integrate the original Bluetooth interface into the Dual Cube LX.

BackConnectivity is completed with the i-Cube Link / Aux In input that allows you to connect a smartphone or headset with a microphone. This input is bidirectional and allows, for example, to record the audio of the Dual Cube LX directly into the tape recorder / camera type application on the smartphone. Great idea to show off on Instagram!

Finally, this amplifier has a USB connection that turns the device into a sound card and offers the possibility of recording in a completely convenient way thanks to the ASIO drivers that can be downloaded from the Boss website.

Let’s end this owner’s tour by noting that the Dual Cube LX is made in China and currently sells for around €300, which is a bit cheaper than its more legitimate rival from Yamaha.

good double?

For these first audio snippets, I used a classic Shure SM57 that I placed in front of one of the small bowls on the Dual Cube LX. Here are the results obtained:

1 – audio chip + frequency

12 o’clock00:30
  • 1 – audio chip + frequency00:30
  • 2 – JC Clean Gain 5 + Frequency00:25
  • 3 – Win an American Combo 5 + Frequency00:32
  • 4 – GC Clean Gain 5 + Heavy Octave + Echo00:22
  • 5 – GC Clean + Course + Echo00:31
  • 6 – Brit Combo Gain 7 + Frequency00:22

  • 11 – Brit Combo Gain 4 + Phaser00:30
  • 12- Brit Combo Gain 4 + Tremolo00:26
  • 13 – JC Clean gain 4 + pulse frequency00:18

As far as it can be said right away, this new cube doesn’t honor the streak that’s always been considered a safe bet with perfectly valid simulations. Here, in general, everything is average. It’s no surprise that the display is a little “boxy”, but it’s really hard to expect better from such a small speaker. The clean sounds in the “JC Clean” and “US Combo” modes are perfectly fine with a small preference for the former, which I found clearer and more enjoyable. Saturation varies greatly. When the crunchy sound of the Vox AC-30TB simulator is somewhat realistic, the Peavy EVH5150 is really disappointing with a very muffled and runny sound despite the extreme parity of trying to correct this defect. The “High Gain” setting, on the other hand, proves convincing with a fairly balanced display and a gain range that covers most patterns between hard rock and more modern metals. The ‘Extreme’ mode, which simulates the MESA/Boogie Dual Rectifier channel, will only be really usable for playing deadly metal riffs and other derivatives. It’s somewhat cartoonish mode reminiscent of the famous “R-Proud” mode found in other more powerful speakers in the Cube series. Overall, I found the gameplay disappointing with notes that are hard to grab under the fingers. Also, lower frequencies quickly become fluid once the gain is increased. The equation is not very interactive, it is sometimes necessary to put the triple layer at 9 or 10 without adding enough.

It was no surprise that Boss combined the most popular effects with a selective and intensity modulation system operated by two potentiometers. These effects are true with algorithms that are probably nearly identical to the entire Cube series. Presentation is sufficient for daily practice.

connected cube

editorThe Dual Cube LX, as we saw in the first part of this test, offers several types of connections. If you have a BT-Dual Bluetooth unit, you can control a lot of the settings that are not accessible on the amplifier board using the Dual Cube LX Editor app. However, this same application is also available for PC and MAC via USB connection. In this aspect, the president has done a very good job. We discover with surprise that very advanced settings for effects have been accessed. First of all, you can select different types of chorus, flanger, buzzer, etc. Then, you can access a bunch of settings for each of these effects. Finally, just save everything in the memories of the Dual Cube LX. A real success for this part of the program! In addition, there is a tuner that, oddly enough and unfortunately, was not originally built into the amplifier.

It’s a pity that Boss hasn’t made an effort to make the Bluetooth part completely original for the Dual Cube LX. The mobile format of this speaker is meant to be taken from right to left, and if almost all of us have a smartphone on hand, that’s not necessarily the case for a laptop.asian

For recording, it is possible to use the mono outputs available on the back or via the updated ASIO driver.
Chief planning. The latter proved to be stable and low in latency during testing. Perfect for doing some things comfortably.

This test couldn’t quite be complete without saying a word about Yamaha’s THR series from which Boss seems to have drawn inspiration in certain aspects. So I got a Yamaha THR30II and let’s be clear, there’s a pretty big gap between the two machines. Yamaha is more organic and fun to play. Of course, my view might be a little distorted by the power difference between the two devices, but the idea is there.

14 – JC Clean Gain 5 – Line Out

12 o’clock00:37
  • 14 – JC Clean Gain 5 – Line Out00:37
  • 15 – high gain stacked gain 10 – line output00:27
  • 16 – metal stack gain 10 – line output00:32
  • 17 – super gain 10 – line output00:20
  • 18 – Gain Brit Combo 6 – Line Out00:27
  • 19 – Gain Brit Combo 6 – USB00:26
  • 20 – metal stack gain 6 – USB00:24


The Dual Cube LX is a small speaker whose audio performance has left us questionable. It’s clearly not a device we’d get for the magic of its simulations. It is a practical, light and easy-to-carry tool. For example, it will be a perfect travel companion for street parties thanks to the battery power supply and stereo inputs and outputs. We can applaud the work that Boss has done on the software to tweak the settings making it possible to improve and patch some of the initial weaknesses of this newcomer to the Cube series. On the other hand, we can conflict with the obligation to use the foot switch to use the looper in addition to the bluetooth module for other functions, which will quickly increase the amount of the bill.
