The Monitor XT35 is a passive center channel speaker built in a shallow, wide cabinet so it can sit below a TV without blocking the screen or the remote sensor. Its front array combines four 3-inch bi-laminate paper woofers with a 1-inch Terylene dome tweeter, and the enclosure uses two front ports. The tweeter extends playback to 40 kHz, and the speaker carries Hi-Res Audio certification. It is described as compatible with Dolby Atmos and DTS:X content.

Besides the center position, the speaker can be used as a left, right or surround channel. Keyhole slots on the back allow wall mounting, and a 1/4-inch 20 threaded insert is provided as an alternative mounting point. The cabinet comes in matte black.

Connection is through nickel-plated 5-way binding posts, so it needs an external amplifier or AV receiver. The recommended amplifier power is 25 to 200 watts per channel, and sensitivity is 87 dB SPL at 1 watt and 1 meter.
