The JVC RV-NB70B "Kaboom" Portable Boom Box (Black) is a high-powered blast from the past, complete with modern features including Bass Enhance and iPod/iPhone dock. It also boasts 40W of total output power, which will have you rocking and bumping up and down your block. Designed for portability, the system even has a modern and tough urban-landscape aesthetic that evokes a rough/cool sensation associated with a bustling metropolis. Plus, it has forty brain-thumping watts.

The speaker system that generates all that power is JVC's twin full-range, sealed drivers and twin Super Woofer subwoofers with Bass Enhancement Function. They're powered by a quad-amp, 4-mode configuration that delivers 15W of stereo output to the Super Woofers and 5W of stereo output to the full-range drivers - yielding 40W total output. Plus, you can listen to your jams at home, or wake up the neighborhood by taking the battery-operated portable boom box down the street or to the park.

Besides the iPod/iPhone dock, the "Kaboom" is outfitted with an FM Tuner, single-CD player, high-speed USB 2.0 host port, and an auxiliary line-in jack for connecting alternate audio sources like MP3 players and laptops. The USB 2.0 host interface if front-facing for quick access and supports playback of MP3 and WMA file types. The CD player supports CD, CD-R, CD-RW, MP3 and WMA file playback, as well as repeat and random playback. The iPod/iPhone dock supports devices 4G or later and also has a composite video output jack for viewing your iPod/iPhone video content on a large screen. The "Kaboom" is even accoutered for karaoke battle. The integrated Karaoke Function uses the system's microphone/guitar input and level control to connect the karaoke mic; how loud it gets is up to you. With so many playback and connection options, the "Kaboom" Portable Boom Box can keep the whole family (or neighborhood) entertained.

    Did some checking around and decided to buy JVC latest boombox. I am impressed how this radio looks and this thing can put out some serious sound! No problems when using with a 2nd generation iPpod/iTouch and can be controlled by a remote that comes with this system. My 16 year old uses it to teach her Zumba class and everyone enjoys the beat and sound. Bit pricey but, in overall, I am happy with my purchase.

    I bought this unit at Boxing Day. Never used it until now as I started working in the backyard. Disappointed to find out that there is no AM accessibility. I love 740 and 1150 AM stations for the old music. I don't know if I can exchange it or return it. I have the old kaboom and it no longer works but it was very powerful and there was AM accessibility.

    Comments about JVC RV-NB70B "Kaboom" Portable Boom Box (Black):

    I use this for my outdoor patio parties and the sound is great, lots of power just like my home stereo system. The Base is very powerful and the other speakers balance out the highs and midrange quite well. I like that my Ipod is enclosed and wont get damaged. The pre-set EQ settings are OK but I would prefer complete manual control. I wish the remote had more control over the Ipod and if the Ipod stayed lit all the time so I can see what song is playing.

      Comments about JVC RV-NB70B "Kaboom" Portable Boom Box (Black):

      I've owned Kaboom for several months. I use it frequently alongside volleyball on grass and beach. Included shoulder strap handy. Protects iPod nicely. Good controls. A bit bulky, as expected. Finish mars easily in car trunk, as expected. More than enough volume, although it delivers only moderate bass for my taste, as expected. Good sound quality. For me a problem is that it requires 10 D cell batteries, and I'd usually need to carry an extra set of 10 with me. Throwing away used-up batteries not good for environment. 20 NiCad D batteries plus chargers would run $200. Instead I use a 20Ah 12V gel battery (15 lb) which I charge with a 15A smart charger. Supplies about 20 hours continuously. Made my own cigarette lighter cord using plug 693-4840. Carry extra fuses with me.

        Comments about JVC RV-NB70B "Kaboom" Portable Boom Box (Black):

        As an audiophile and electronics retailer, I know when I see a good product: this is. The sound is impressive both in volume and quality. The bass can get a bit muddy at higher volumes with the bass turned all the way up; but there is a dial on the top that makes it very easy to fix this problem. Also, this thing has just about everything: Mic input that can also be used for electric guitars, Aux Input, and a video output for the ipod dock. It also has the features that you would expect from all boom boxes. Bottom Line Great Product for the money, And a great product over all.

        I'm a 65 year old woman who never was drawn to boom boxes, but I am totally thrilled and appreciative of this JVC Kaboom. I searched every nook and cranny on the web for a portable CD player that had decent sound and was continually disappointed until I got this Kaboom and the quality of construction and sound is stunning. I am beyond pleased. Even though it has many other great features, I was really looking for a really good portable CD player before you can't find them at all.

              I use the kaboom for audio in exercise classes that I lead. The sound easily fills the room, including elementary gymnasiums. This is one of the few boom boxes that provide input from both CD media and apple products. I could only give four stars because the kaboom is bulky to carry to and from classes. If it did not need to be regularly portable I would rate it at five stars.

                  I use this boom box as an audio refrecence while recording video clips on Havana and yes is heavy but at the same time so loud ( with no distortion ) that the singer can stay on track beside the street noise on the city.

                      Husband uses it to sing at various functions instead of a much larger system with head, c/dpayer or computer and speakers. It delivers a great sound and is easy to use in case I can't be there to do music for him. Just wished there was a way to control mic volume and some reverb would be great also. Price was very reasonable for what you get.
                      Have not found anything major against recommending someone else purchasing it. We do not have an ipod, so that is wasted on us, but available if we desire to go that way in future.

                      Did some checking around and decided to buy JVC latest boombox. I am impressed how this radio looks and this thing can put out some serious sound! No problems when using with a 2nd generation iPpod/iTouch and can be controlled by a remote that comes with this system. My 16 year old uses it to teach her Zumba class and everyone enjoys the beat and sound. Bit pricey but, in overall, I am happy with my purchase.
