I was washing my car in the driveway today and needed some tunes to get me motivated, but I couldn't decide which box to use so I chose 2: my JVC Kaboom and my M70. I loaded up Earth, Wind & Fire's greatest hits on the mp3 and used a splitter to connect to both radio's line input. I put the volume on both radios to about 3/4 and the sound was incredible!! Together they make the perfect box! No individual box could touch these two together in sound quality, volume, bass and clarity...but which one is better individually??? I decided to find out. The kaboom clearly outshines in the bass category hands down, but those 3 inch mids can't seem to pump out enough midrange and highs to balance out the thunderous bass. The sound is rich and deep but it feels as if your not hearing all of the music. Where the kaboom is lacking the M70 shines, the mids and highs come in so clearly that you can hear every voice and instrument in the song. The bass is crisp and clean but not thunderous. So if you are listening to music where the vocals and instruments are the focus the M70 is the clear winner. If you are listening to music where the bass is the focus(like most of todays music) and the vocals and instruments take a back seat then it's the kaboom, but the M70 is just so nice to look at and the overall volume is louder so my personal choice is the M70...but as I said earlier together they make the PERFECT bbox.
