Immaculate and great sounding monitor system small-medium small rooms. The BM5 MKIIIs have a 7in woofer and a 1.1 inch tweeter. These guys can produce up to 118db. (That's loud) Add the sub which is 9.5 inches and 300 watts, and you get full, deep, accurate monitoring for almost any type of music. Am selling because we're changing the space. From Sound on Sound: "Overall, the sound has the expected Dynaudio attributes, which means it comes over as well balanced, with crisp and open-sounding highs that do not at all sound harsh. There’s also a creditable sense of front-to-back perspective in the sound, especially considering that these are not esoterically priced speakers. Importantly, the speakers are able to expose the flaws in poor mixes as well as sounding good on high-quality material. Voices come over as sounding extremely natural, which is always the hallmark of a good speaker." "Add the sub and the lows become deep and visceral, far belying the small size of the sub. Taking the low-end load off the main speakers also means you can work at an even higher SPL without the speakers sounding strained, though to be fair they can go pretty loud anyway before they start to sweat. Fortunately, the lows always manage to stay adequately tight-sounding, as the use of a sealed subwoofer cabinet helps reduce overhang."
