A: Hello. Thank you for your questions, and we appreciate your interest in our products. The speakers come with a wall bracket and are designed to sit flush against the wall. With it being flush, you have a nice clean look and don't have a gap between the wall and the back of the speaker. We hope this helps and thank you again for considering us for your purchase.
A: Thank you for your question and we hope all is well. Yes the SLM can be used as any speaker in a home theater application. The Folded Motion tweeters have an 80° x 80° dispersion pattern, which allows SLM and SLM XL to sound exactly the same in a horizontal or vertical orientation, making them perfect for Left-Center-Right (LCR) system applications. We hope this helps and thank you for your support.
Q: Would these work in an LCR setup behind an acoustic transparent screen?
A: Yes. They sound great. I have 2 SLMs for L/R and 1 SLM CL for C. Though not behind a screen. Any speaker will be compatible with an acoustically transparent screen. That said. If the have enough room behind the screen. I’d use 3 towers for LCR, something like 3 Motion 20i or 40i. You’ll have more natural sound experience. SVS and KEF also make fantastic towers. Good luck

Overhaul your sound system with this MartinLogan Motion SLM XL speaker.

This MartinLogan Motion SLM XL speaker has a Folded Motion tweeter that delivers accurate high and mid-range tones.

The flagship of the series, and largest “LCR” model in the Motion XT CI series includes a unique feature that brings its performance level up even higher. In addition to the FMT XT tweeter, and dual 6.5” woven Kevlar Nomex-backed bass drivers, the XTW6-LCR has a dedicated 6.5” midrange driver that elevates its acoustic performance to rival that of traditional floor standing speakers. With a rotating tweeter housing, the XTW6-LCR can be used horizontally when needed, and is the perfect choice for systems desiring a higher level of performance without the large footprint of a tower speaker. The MartinLogan Motion XT CI series takes performance to the next level over Motion CI. The Folded Motion XT tweeter gives each model in the Motion XT series even more of the clarity, output, and efficiency that the standard size FMT is famous for. With Motion XT, we wanted to increase all aspects of performance over the Motion series, so we didn’t just stop at the tweeter. All Motion XT models feature woven Kevlar woofers for increased rigidity and lightness which translates into better sound. In addition to the larger tweeter, and lighter, stronger woofers, MartinLogan’s design and engineering team has fitted the Motion XT series with a more substantial chassis to strengthen the speaker and provide a more accurate sound, like a better cabinet on a traditional speaker. With Motion XT CI, the difference is in the details. No matter which Motion XT CI speaker you choose for your room, rest assured they are designed to provide a consistently high level of performance and can easily be used with other MartinLogan speakers to make creating the perfect system for your unique listening space that much easier.

These speakers are great. They sound amazing and look great as part of our new Dolby Atmos system. You do need a good subwoofer to bring out maximum sound.

These are really nice looking and great sounding speakers. I love the slim profile with then hanging on the wall. I use this one as my center speaker. If youre using these as stereo and center channels, you need a woofer. The sound clearity is amazing but there is very little bass out of them. Dont let my photo deceive the size of the speaker. I have an 85" tv in the pic.

Nice sleek look and great sound. Can be installed on wall or comes with speaker stand. Great installation by Best Buy technician on wall with hidden wires behind the wall. These take up less room than bookshelf speakers. I have total tech membership so all my electronic and computer purchases come with a two year warranty for free.
