MartinLogan Motion SLM X3

Yes, this is a passive soundbar, meaning it does not have built-in amplification. You will need to connect it to an external AV receiver or amplifier to power the three discrete channels.

Absolutely. The SLM X3 includes a kick-stand, allowing you to place it securely on a media console or shelf directly below your television.

Given its frequency response starts at 120 Hz, the SLM X3 is designed to handle mid and high frequencies exceptionally well, but it will lack deep bass. For a complete home theater experience, we highly recommend pairing it with a dedicated subwoofer to handle the low-end frequencies.

Folded Motion tweeters use a pleated diaphragm that moves air much faster than a traditional dome. This design results in lower distortion and a wider, more detailed soundstage that mimics the clarity of MartinLogan’s high-end electrostatic speakers.

It is compatible with most standard receivers, provided they can handle a 4-ohm load. Since it is rated for 20–140 watts, ensure your amplifier is capable of driving 4-ohm speakers to get the best performance.

Yes, the SLM X3 is specifically designed as a 3-channel L-C-R (Left-Center-Right) soundbar intended for horizontal mounting. It includes the necessary wall-mount bracket to sit flush against the wall.
