JVC RV-NB70B "Kaboom" Portable Boom Box (Black)
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'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.

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

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

You can not go wrong with this product, the sound is clear and crispy, the bass is great and enhances the music I like. I bought a microphone, and know I can sing along with the music I play. Hopefully for the next generation, they include the HD radio.

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