If you are mixing drums you need the HS-8's period. They are Yamaha's largest studio monitor and you want that so you can mix the bass right in your drum mixes. Combine with the HS8S subwoofer to work on those super low frequencies. While not mixing enjoy a very detailed and accurate listening experience. We also have users buy these for surround systems in home theaters. A great speaker! Sold as each so if you want a pair buy two of them.
