PreSonus' range of Eris monitors is made up of the compact E4.5s, slightly larger E5s and the largest of them all, the E8s, which provide the deepest bass response out of the three. All have made quite a name for themselves as speakers that offer a very neutral response across the entire frequency range, especially give their low price.
Anyone who purchases a pair of Eris E5 or E8 monitors before the end of March 2014 will receive a FREE download of PreSonus' Studio One Artist DAW for recording and mixing.
