About the PreSonus Ceres™ C4.5 BT

Versatile performance and wireless convenience for studio or home

We've seen our share of powered studio monitors here at Crutchfield, but the PreSonus Ceres 4.5 BT are the first we've ever come across that offer the convenience of wireless Bluetooth audio. They make it a snap to enjoy music, movie and video game soundtracks streamed wirelessly from your compatible smartphone, tablet, or computer. But these versatile monitors don't stop there. They also give you the pro-quality sound and accuracy that PreSonus monitors are known for, plus a flexible set of connections and controls that make them easy to integrate into your studio or home system.

PreSonus Ceres C4.5 BT

The versatile PreSonus Ceres C4.5 BT monitors deliver outstanding sound for the home or studio with the added convenience of wireless Bluetooth playback.

We've seen our share of powered studio monitors here at Crutchfield, but the PreSonus Ceres 4.5 BT are the first we've ever come across that offer the convenience of wireless Bluetooth audio. They make it a snap to enjoy music, movie and video game soundtracks streamed wirelessly from your compatible smartphone, tablet, or computer. But these versatile monitors don't stop there. They also give you the pro-quality sound and accuracy that PreSonus monitors are known for, plus a flexible set of connections and controls that make them easy to integrate into your studio or home system.

Flexible connection and control options

Although the Ceres 4.5s function as a pair, the amplification, connections and controls are all found on the left speaker, which provides signal and power to the right speaker through a regular speaker wire connection. One pair of balanced 1/4" TRS inputs and a pair of unbalanced RCA inputs give you flexibility for line-level input. You also get a 1/4" TRS subwoofer output for plugging in a powered sub. Handy front-panel 1/8" aux-in and headphone output jacks add to the convenience.

PreSonus knows you don't always have control over the space you're working in, but the C4.5 has you covered. Separate bass and treble controls let you create a more accurate listening environment. If your work takes you overseas, the C4.5 also has an "AC select" switch so you can adapt to voltage requirements outside the U.S.

Features

Two-Way Active Speaker: Each CERES C4.5BT loudspeaker houses a 1" low-mass silk-dome tweeter and a 4.5-inch Kevlar low-frequency woofer powered by a 25W Class AB high-current amplifier. The PreSonus Ceres C4.5BT active speakers deliver professional sound quality that lets you hear your music clearly and accurately.

Bass Reflex Enclosure: Each active Bluetooth speaker features a Bass Reflex enclosure with a rear-firing bass port that adds greater efficiency and even bigger bass response.

You'll be able to wirelessly stream stored music and music apps on  your Bluetooth-enabled device to the CERES C4.5BT speakers. You'll still use your Bluetooth-enabled device to control music playback and view song/artist information.
