The Harbeth Compact 7ES-3 are a set of studio and hi-fi monitors, suitable for a variety of purposes. Harbeth is a company out of the UK, and is one I didn't know about until I tried out these monitors. We have these up as main monitors in the B room at the studio where I work, used in tandem with another set of monitors. The Compact 7ES-3's are passive monitors, so they do require an external power amplifier, although I'm not 100% sure on which amp we have hooked up with these right now. They are pretty large monitors, bigger than most but not the biggest I've seen out there by far. These monitors can be used across the board, but my experience using them has been during tracking and little bit of mixing. Without a doubt, these are some of the most precise and accurate sounding monitors that I've used to date. For tracking, the sound comes through exactly as it sounds going into the mics, and the few mixes that I've done on these monitors translate as well as any monitors I've used, which is really the name of the game as far as I'm concerned with monitors. I haven't seen these monitors anywhere other than the room that we've got them in at the studio where I work, although since they are from the UK I would imagine that they are more widespread over there. I also don't really know what kind of price the Harbeth Compact 7ES-3's will cost, but judging from their quality I would think that they're quite expensive. Either way, if you're in the market for a set of high end passive studio monitors, there's no way you can go wrong with these monitors as they are simply awesome and need to be heard to be fully appreciated!
