There is just one prerequisite: you simply have to cost this suitcase of yours for it to play songs for you.

South Korean shopper electronics agency LG’s X-Growth RK3 (or Celebration Audio RK3) is such a ‘suitcase’ albeit a completely locked one, however you don’t have to unlock it to get the promised goodies. For the goodies of music are distributed to every person, with out discrimination by the central woofer with the assistance of the inbuilt rechargeable battery sitting contained in the speaker unit.

We performed this ‘suitcase of sound’ over a span of some weeks to see if it could please music-lovers and justify its MRP of Rs 19,990. Here’s what we discovered:


The X-Growth sequence of mini and micro HiFi audio programs by LG have been launched available in the market as all-in-one (unibody) party-centric audio system. A few of these are the LG X-Growth OK99 (MRP- Rs 49,990), the X-Growth OK75 (MRP- Rs 32,990), the XBOOM OK55 (MRP- Rs 24,990) and the X-Growth Useful at an MRP of Rs 15,990.

The highest panel of the RK3 speaker unit homes two columns of buttons alongside the physique, flanked on each the edges by rotatable knobs — mic vol. (to regulate microphone quantity) on the left facet and major vol. (to regulate the speaker quantity) on the correct facet. The utmost permissible quantity (that may be seen on the show) by means of mic quantity is 15 and that by means of the principle quantity button is 40.

The centre of the highest panel consists of two sequence of buttons, the left one near the mic quantity knob and vice versa. The left-side sequence of buttons includes of soft-rubber buttons for energy on/off, vocal results and echo/demo, key changer buttons, and a voice canceller button for karaoke. The opposite sequence of buttons includes a operate button to alter the enter modes, buttons to alter the tracks, a reset/repeat button and a sound impact/bass blast button.

As we talked about earlier, there’s a telescopic adjustable deal with to hold the unit round. The deal with might be adjusted to 3 completely different lengths relying upon your want. Near the deal with lie the ports — Mic In, USB and Port In — lined by a protecting rubber port cowl.

The entrance panel is taken up majorly by the 6.5’’ woofer unit protected by a metallic grille.

The rear of the speaker unit homes a built-in valve regulated (12 V/7.0 Ah) lead-acid rechargeable battery. The battery is non-removable. Below one other rubber port cowl, a battery-charging indicator, energy on/off switches to modify the speaker on/off and an AC socket for charging.

The speaker’s dimensions are 370 x 480.5 x 310 (W x H x D) mm and its gross weight is 12.3 kg. The physique is made up of sturdy sturdy plastic and will face up to a couple of hits and knocks. Each the edges have depressions in order that the unit could possibly be lifted simply with each the fingers. A pair of wheels is current on the backside to facilitate shifting it round.

No FM antenna was included within the carton though it says on LG’s web site that it comes within the bundle.


The speaker took 7-8 hours to cost fully. As soon as totally charged, it gave a powerful again up of 9-10 hours on common. The battery might be charged even when the unit isn’t on. One can take heed to music whereas charging the speaker in ‘on’ state.

With 320kbps information of Snow Patrol’s Chasing Automobiles, Run and Open Your Eyes at 70 % of desktop quantity, 24 % of Win 10’s Groove Music and a major quantity degree of 28 on the RK 3 (most doable quantity is 40) and with ‘Rock’ on the equalizer setting, it felt as if Gary Lightbody had determined to carry the band’s present for you solely. Listening to him sing with the speaker unit 15 toes away from us, his vocals deeply-tinged with disappointment and longing, felt as if he was there with you within the room, in a one-way personal musical dialog with you, singing his woes and his hopes, compelling you to drop every little thing, something that you just had been doing, simply to take heed to him and the band.

The sound surrounds and envelops you, makes you are taking a dip in its assorted moods as per your most well-liked music genres be it Rock, Pop or Digital. It’s balanced, not room-shaking loud however loud sufficient and might be equalized as per your music tastes. When you’ve bought the music flowing from the RK3, you’ll be able to take heed to it for hours on finish with out getting a headache, even on loud volumes. The bass feels optimum; it doesn’t intrude on the territory of treble and mids and might be elevated through the Bass Blast/Blast+ setting if you would like that further punch.

The speaker output sounds nice on 320kbps information and above however not that nice on low-bitrate information. At most quantity, a slight distortion was felt, that too in some guitar-centric tracks.

With low-bitrate information of Comfortable Rock, Pop and digital music, be they MP3s or YouTube music movies, the speaker gave a passable listening expertise with little or no distortion at full quantity. Nevertheless, audio replica of low-bitrate information of genres like Exhausting Rock, Grunge and Heavy Metallic felt missing in audio steadiness. Nonetheless, the X-Growth RK3 was in a position to handle each the low and high-bitrate information of well-liked musical genres.

The USB operate doesn’t work with all kinds of USBs, as talked about by LG itself within the speaker handbook. The suitable USB units are a Flash-type MP3 participant, USB2.0 or USB1.1. A number of pairing of Android units shouldn’t be doable.

A few of the pre-set sound choices that may be accessed by means of the sound buttons are Pop, Basic, Normal, Rock, Jazz, Bass (Bass Blast) and Bass+ (Bass Blast+).

To verify the Bluetooth-connectivity, we stored shifting the speaker (the wheels and the telescopic deal with had been very helpful) round in a number of rooms (with partitions to hinder the connection) and stored the laptop computer/smartphone stationary and vice-versa, and the Bluetooth connectivity labored very effectively until nearly 30 toes (about 9 metres) and began breaking off after that.

This speaker may reproduce and sustain with the sonic vitality of bands like Nickelback and Bullet For My Valentine.

You would want a microphone for karaoke as a result of the speaker doesn’t include one. Voice canceller doesn’t cancel the voice however drastically lowers the lead vocal quantity preserving the backing vocals untouched — which we beloved — whereas on the identical time rising the amount of the accompanying music, and generally decreasing the sound of acoustic devices too, thus permitting you to guide the vocals as a substitute and belt it out fortunately. The mic quantity might be adjusted to be loud sufficient for a giant corridor with a dimension of 33 x 36 x 26 toes (L x B x H) and can be enough for outside ‘karaokeing’ with a small group. There are 18 vocal results at your disposal like Bass, Soprano, Helium, Robotic, Duet Man, Duet Lady, Echo1 and many others. to deliver a bit, generally humorous selection to the voice output.

The pair of wheels current on the backside shouldn’t be very appropriate for uneven unpaved roads. In any other case, they do an admirable job whereas shifting the unit round.

Coming to the issues that we desired on this speaker, we needed an audio enter cable because it doesn’t include one and a remote-control unit too for ease of use. There may even have been an choice to play it with the assistance of an exterior energy provide.


The LG X-Growth RK3 has been designed preserving the occasion lovers in thoughts. Particularly when you find yourself partying outside and your concept of getting enjoyable constitutes of hanging out along with your gang, getting tipsy whereas listening to music and belting it out whereas doing karaoke. The transportable grab-and-go unit with wheels and an adjustable deal with, its splash-proof (IPX4) sturdy design, the karaoke characteristic, lengthy battery backup, robust Bluetooth connectivity (that labored flawlessly until 25 toes) and many others. are all an affidavit to this truth. Whereas it’s constructed for partying outside, it’s equally competent indoors too.
