I bought my first pair of Monitor One speakers from Alesis when they first came out over twelve years ago. I used them for front speakers in a home theater sound system, for recording studio monitors, as stereo speakers in my home audio system, and I've used them as PA speakers for practice drum sessions. Except for a tweeter that blew about eight years ago (and Alesis was GREAT! providing a replacement tweeter) these speakers are still going strong. You will not find a more robust, better sounding pair of studio monitors for the money, especially at the sale prices being offered now (3/4/10). In fact, I just ordered my second pair of Monitor Ones on Tuesday. I've been overdue for a pair of the MK IIs, which are magnetically shielded. The original Monitor Ones are not magnetically shielded, something to keep that in mind if you're looking to buy used. You'll want a magnetically shielded pair if you plan on housing the monitors near a TV or computer.
