That octet of D batteries will add some weight to the unit, which comes in at 10.1 pounds (without batteries) and measures 7.7 inches high by 19.7 inches wide by 9.3 inches deep. Needless to say, this is one of the bigger portable iPod speakers out there and you probably won't want to lug it too far. But carrying it out to the patio or pool shouldn't tax you.
Thanks in large part to its side-firing 5.25-inch subwoofers (one's active, one's a passive radiator), the Mix is designed to play loud and fill a good-size room with sound. The unit also contains two 3-inch midrange drivers and two 1-inch horn-loaded tweeters, and you can adjust the bass and treble settings using the EQ settings button on the remote or on the unit itself.
Overall, we were pretty impressed with what we heard. There's good detail, and the system is well balanced (read: smooth), with no big holes in the high, low, or midrange. And what's immediately clear is that this thing has some serious kick to it. The Mix may not be able to take the place of a true component-based system, but it does sound bigger than it looks, and the bass really thumps. Indeed, this makes for a great party box.
For our testing, we used a wide range of music, including some Elvis Costello and Dan Auerbach, as well as more popular club hits from Lady Gaga and Rihanna. The Mix acquitted itself well with all of it and outperformed the identically priced iHome iP1, which we had sitting next to it.
In the end, while its retro styling may not appeal to everyone, the Mix iMT800 is a well-designed and versatile iPod speaker that you should strongly consider if you're looking for a system that sounds good, has some oomph to it, and is portable (or at least luggable). We have no reservations recommending it.
