CNET Editors' Rating

The Good Deep bass tones. Variety of inputs, including iPod, USB and Guitar Video output.

The Bad Huge bass control only has six level settings. iPod cover falls open too easily. No DAB+ compatibility.

The Bottom Line The BoomBlaster RV-NB70B is big, bold and brash, but we wish that it was ever so slightly better built.

7.5 Overall


It's fair to say that you're not going to be interested in the BoomBlaster unless its particular mix of 80s Ghetto Blaster style with modern inputs visually appeals to you. After all, at 666x231x 240mm and a hefty 6.8kg carrying weight, it's not exactly a subtle music option. It does have some aspirations to being portable, with the capability to run from a whopping 10 D-Cell batteries, although they'll also add to the carrying weight.

The one thing that we expected to find on a box like this was an easy top-mounted carrying handle. No luck, though; where a handle might have been placed is the pop-up CD tray, locked down with a circular dial. Instead, the unit comes with a single "guitar-strap" that hooks onto the sides. Around the front, under another circular dial, is the cover for the iPod dock, while at the back you'll find inputs for external audio sources, including a selectable switch for guitar or microphone input, along with a level control. It'd be feasible, therefore, to use the RV-NB70B as a small portable amp.


The RV-NB70B's total output for its size is 40W, spread across two 5W main speakers and two 15W subwoofers; as such, it's not surprising that JVC's touting the RV-NB70B as a bass-thumping machine.

In terms of input formats, the RV-NB70B supports iPods of all types, and is shielded for iPhone audio, although the cassette deck-style dock makes it tricky to operate any touchscreen iPod or iPhone with any degree of finesse. Video outputs on the back make it feasible to run video from an iPod or iPhone over composite connections. CD audio is also supported, and the top-mounted tray will also read MP3 and WMA files, as will the front-mounted USB host port. Radio is also supported, but only FM, with no inbuilt DAB+ facility.
