PreSonus Ceres BT speakers are based on our Eris line of studio monitors. Since studio monitors are designed to provide extremely accurate sound, Ceres speakers give the listener a very detailed reproduction of the program material.
Granted the tuning of the Ceres is modified relative to Eris in order to accommodate the design, such as the grilles over the woofers. The internal volume of the Ceres enclosure is different in order to handle the Bluetooth electronics. However we have tried to keep Ceres speakers as accurate and detailed as the Eris studio monitors.
Of course speaker placement is always important so please be mindful of placing them close to walls and corners, if possible. But there is no need to set up your Ceres speakers in an equilateral triangle unless you want to. You can set them up as you would any pair of stereo speakers in order to accommodate your room.
