PreSonus Eris E4.5BT Bluetooth Monitors

The Eris line of studio monitors from PreSonus provides powerful, balanced sound perfect for referencing mixes and mastering in the studio. The Eris E4.5BT expands this offering with Bluetooth built in. The 4.5-inch main woofers are crafted with a woven composite material that—alongside the rear-firing bass port—delivers solid bass performance without too much boom and resonance; while the one-inch silk dome tweeters add a delicate performance for the high end. The Class AB amp brings with it 25 watts of handling for each speaker, ideal for nearfield use in the studio. The inputs and outputs are where the E4.5BTs really differentiate themselves, though. There are balanced quarter-inch inputs for main monitor connections, plus RCA and unbalanced options, and a front panel-connected headphone amp. The Eris E4.5BTs also offer wireless connectivity via Bluetooth 5.0, great for connecting quickly to a variety of sources.
