I had been using some Yamaha monitor speakers in my home studio for many years, and thought I was happy. Then I heard some powered Alesis monitors and was intrigued. I knew I was missing something. I started doing some research and it was clear based upon all the positive reviews that the Alesis Monitor One MK2 speakers had something special. I ordered them (how could you not at such a low price!). When I received them I had the thought that if they didn't work out, showing a clear advantage, I could return them. On first listen, I was startled! Was that really my favorite music? But, wait a minute, listen to all that detail.....oh, oh, I was hooked. Then I REALLY ran them through the paces. I am driving them with a MacBook Pro, Logic Pro, ART SLA1 100 watt studio amp. Oh, boy, now I understand why my mixes always came out different on my monitors than how they sounded through other systems. All I can say is, the Alesis monitors are incredible, just amazing. I listen to them at a fairly high volume, and honestly cannot get used to the clarity. It seems I am stepping into the music, and can find EVERY part now clear as a bell. It's like I just took my listening experience out of a muffled room, and came into the open for the first time. Just a very, very nice experience. I'm looking forward to using these for many years. I would buy them again, without hesitation. Alesis has always been a good value, and with these monitors, they continue to impress.
