JVC RV-NB70 Kaboom review: a big sound in the small boombox and iPhone instead of the cartridge

I knew long ago about existence of such term as "boombox" and speech not about Russian to group, and about the device. It is own sort the street musical system, capable is juicy to rumble and work far from an electric network. Practically, autonomy and relative compactness also distinguishes devices such from house minisystems. Though, there is one more printsipny moment — a form factor. Modern I rub the boombox kept such feature of own primogenitor, the two-cassette tape recorder as pair of huge built-in columns along the edges, but its form exchanged, it from angular became cylindrical. Vperva I fleetingly faced the real boombox more than 10 years ago and me struck both its form, and a given-out sound. At present it was possible to test such piece without the aid of others, at all this piece not simple, but directed on introduction together with iPhone, iPod and even an electric guitar.

Brutal cylinder

JVC RV-NB70 Kaboom review: a big sound in the small boombox and iPhone instead of the cartridge

«Brutal and portable» — directly such expression came up, when the companion dragged JVC RV-NB70 Kaboom on test. Severe appearance, a belt for carrying, rough qualitative plastic, pair of big handles from above, the bent lattices of loudspeakers — all these details in aggregate form very visible and unusual accessory, directly an accessory, in a different way and will not tell.

By the way, so unusual form at it not simply so. The similar design of a sound pipe allows the small, 7-kilogram device to give out fervent звукан. By the acoustic possibilities it absolutely can посоперничать with house sound system Logitech Z5500. The last, naturally, more feasibly and a little basovity but if to start to unscrew loudness on a maximum, in both cases there is a fear about integrity of glasses in a room and the heads.

And it is concrete, pair of 13-centimetric low-frequency radiators is built in sides of the boombox, and on the forward panel two shirokodiapazonny loudspeakers a diameter on 8 cm are located, and that the most interesting — for each loudspeaker is the certain amplifier. The general capacity of acoustics makes 40 Watt of RMS that in comparison with 100500 Watts about which write on «the Chinese rattles», it seems not enough, but, believe, the device rumbles as it is necessary. On bigger loudness nearby it is heavy to stand, if the device plays in a small room. Not including that, it is really working 40 Watt on which acoustics does not rattle and not пердит, and "swings" the most powerful sound, and at the same time all round, including neighbors on pair of floors up and down.

Therefore costs with a significant shred of scepticism and irony to treat hundred parts Watt of the capacity, written on devices not the most known companies. Well and terrible vendors in cheap products too quite often dissemble with capacity, specifying peak properties only for the amplifier (which, usually, can give out even more than radiators are capable to reproduce) or for loudspeakers which will play so some minutes and "will burst".

In this case the boombox far not from cheap, on start of sales last year cost $450, and now the price for it fell to $300-350. However, this unit for our market quite rare that bears in itself some inconveniences, but about them we will have a talk later, as well as about a sound. For now we will more in details study the device outside.

iPhone instead of the cartridge

In the top part of JVC RV-NB70 the CD player settles down. It is possible to tell that the archaism but while disks are still actual, the device understands plus not only Audio CD, but also the MP3 and WMA files which have been written down on CD R/CD-RW.

The mechanism of discovery of a cover of a CD player is interestingly made — it is necessary to turn the small handle. A trifle, adding stylishness and the general brutality to the device. Besides is at it and functional loading — such lock a case will not reveal when carrying and jolting boombox. After all it is portable acoustics.

Pair of powerful handles which I mentioned above, are responsible for bass and loudness level. The course at their soft, is slightly remarkable click during turn. As a whole, they very much комфортабельны. Near are заушины for fastening of a humeral belt — it is executed from rigid and strong nylon, but accessories plastic. As it seems to me, metal would be here superfluous. If the belt disturbs or it simply is not necessary, it can be unhooked simply, and two "crossbeams" will promote in carrying on lateral sides. First thought about them as of decorative elements, but late in the instruction read that after all they for carrying there are.

Between forward loudspeakers the main unit of management of the device and dock for iPhone or iPod settled down. On the design it reminds old kassetnik, only instead of the cartridge iГаджет is inserted. A latch same, as well as in a CD player. Dock quite spacious and I simply contained in it iPhone 4S both with a karbonovy slip, and with Clever sticker. It is a pity only that no emphasis or the fixing mechanism for the portable device of Apple inside is provided and, in fact, it keeps only on the socket. It not discrepancy when the boombox costs on an equal surface. But here to transfer it with iPhone inside costs accurately, and it is better to take out phone or a player in general in that case. Over dock there is a monochrome LCD display with blue illumination, it hours.

Also JVC RV-NB70 contains the FM receiver and alarm clock function. At desire of the user the device can wake him in the afternoon a favourite melody. The dock is compatible practically with though by what iPhone and iPod models, in the latter case times the complete adapter can be demanded.

But even if iГаджета available is not present or it someone from members of the family (for example, the child took to play), in other words in a flash borrowed the next option how to compel the boombox to play, not including uses of a musical disk or FM radio. Take though what flash drive, write down on it the loved music and connect to the relevant port in JVC RV-NB70, hiding under a folding shtorka. As well as in a case with CD, acoustics understands the MP3 and WMA files. The unique minus of work with flash cards — this absence of any sorting or support of separate folders and playlists. From the store everything is reproduced.

To operate a gadget very easily, the child will understand also. All necessary buttons are assembled in 2 blocks along the edges of dock. For each of sources of a sound there is the копка activation and a playing/pause, there are general buttons of switching of tracks and a playing stop.

Under the right block window IK-priyemnika for the DU panel takes place. By the way the panel most that on is oldskulny, big and with malekhanky, soft, rubber keys. To someone such, can be and are pleasant, but I would prefer something more modern and thin, the Apple Remote type

With the beautiful and brutal boombox some is delivered strange and the DU powerful panel

Here such handsome would amuse more

On the back panel it is possible to find many any holes and the telescopic aerial for the FM receiver. The most part of holes conduct to fixing болтикам, they are not necessary to the ordinary user, only the service center. Interestingly, why at each such opening the arrow is drawn? That the languid servisnik did not thrust a screw-driver not in that hole?

Under the aerial the block of more suitable openings is located, and is direct: the network socket, an audioentrance, an exit to earphones, a composit video output for an image conclusion with iPod/iPhone on a TV set and a special counter of specifically this model — a 6,3-millimetric entrance for an electric guitar, in it it is possible to thrust a microphone and to arrange a karaoke.

Also there is a similar RV-NB50 model by musical possibilities, but in it there is no video output and a guitar and microphone entrance. Wishing can save up guide attention to it.

In the lower part of the device behind a small cover the voluminous compartment for 10 R20 batteries hid. However, I did not find mentions of time of independent operation of the boombox.

JVC somehow magnificently arrived at the time of when devices eating from the power supply network generally are equipped with the universal power unit working both at 120 volts, and at 220. It is dependent on the region at which JVC RV-NB70 Kaboom is aimed, in it the corresponding BP — or under a 120-voltny network, or under 220-voltny is established. In this case the 1st option got to me, and it was necessary to use some hellish transforming adapter. It, naturally, universal and all such multipurpose, well and in the sizes not the small. Generally, will choose such boombox or JVC RV-NB50 — pay attention to its requirements to a food.

Megasound

Well, here we also reached the most interesting and the most head that is in a considered accessory. Slightly earlier I a little mentioned given-out JVC RV-NB70 Kaboom a sound meaning that it powerful, at present let’s discuss its quality.

Having thoroughly had heard plenty by means of the boombox of various music I thought a simple thing — such speaker systems are aimed Only at dancing, electronic and heavy genres. The classics, the opera — better and not to try to listen to such music by means of JVC RV-NB70/NB50, will be very disappointed. But when the melody is filled with low frequencies, a bass, a rhythm — here then the device opens itself in all beauty. In particular abruptly it sounds at installation of an equalizer of Beat (there is still Pop, Flat and Clear).

The sound big, powerful, at all this does not hammer a continuous bass neither average, nor high frequencies, acoustics sounds is rather balanced, though accent, naturally, on low frequencies. But, I will repeat, strikes dimensions of sounding that in particular it is appreciable on some tracks, like that below:

First music plays silently, is weakened, and on the 40th second «low-frequency meat» is cut, and JVC RV-NB70 Kaboom actually blows up, filling with the SOUND all room and the listener. It very much, it massivno, it «tears a roof» in good sense of expression. The bass swings so that in a stomach gives, and the head inadvertently shivers in a step to a rhythm. Such feelings stand high. In particular, if so compact acoustics can provide them. I test similar feelings and from attached to the personal computer with the Sound Blaster X-Fi sound card of acoustics of Logitech Z5500, but in it one subwoofer weighs as three boomboxes. And still smartly sounds different dabstepishche and Drum&Bass. For example, Nero:

I do not know, how JVC achieved such effect, but the fact remains — small 7-киллограммовая portable acoustics is capable to undermine simply a brain of the fan filled with Bass, a rhythm and low frequencies of music. Тяж too perfectly sounds. Perhaps, one of events is the cunning design of the boombox, its form and actually application to a meeting of 2 subwoofers. After all each low-frequency loudspeaker is isolated and possesses the fazoinvertor. And there can be it simply special Japanese magic.

As a result of JVC made smart, but quite uzkonapravlenny on genres the acoustic unit for owners of iГаджетов. It is a fine choice not only for those who needs the uncompromising portable decision, well and for the people constrained in a living space. The small boombox is capable to rumble as "adult" computer acoustics or home theater, it is universal, works with CD disks, flash cards, contains the FM receiver and an alarm-clock. The built-in audioentrance allows to use it as external acoustics for the personal computer or TV, and wish — can arrange a karaoke a party, having connected to the device a microphone, well and with an electric guitar it is possible to be indulged. If a microphone/guitar are not critical, safely we save and we take the JVC RV-NB50 Kaboom model (but it does not support iPhone, only iPod(!)). Is a pity only that such device is absolutely not widespread on the native market.

The founder expresses gratitude to Igor Osipenko for acoustics of JVC RV-NB70 Kaboom provided on the test.
