Delivering extraordinary audio experiences and exceptional performance via system intelligence and premium components, the LS118 is the result of a deep understanding of customer needs and application requirements. The LS118 is easy to configure and deploy for applications ranging from simple, portable, plug-and-play setups, to demanding, networked, high-tech AV productions and fixed installations.

Featuring QSC Acoustic Linear Phase (ALP) design, which permits effortless combination and coherent deployment of QSC loudspeakers within the same sound system, the LS118 also provides daisy-chain connections for analog, networked digital audio (Dante®) and AC power (PowerCON TRUE1). Two or more LS118 can be configured in a cardioid arrangement, maximizing low frequency output in front while minimizing unwanted energy around the sides and rear of the system.

Together with the LA108 or LA112 active line array loudspeakers, the LS118 can be deployed with either an array frame/ground-stack adapter or using loudspeaker poles in both horizontal and vertical orientations.

Features

  • Very high output (138 dB peak SPL) with impressive low frequency performance
  • Purpose-designed, 18-inch (460 mm) long excursion direct radiating driver
  • Energy-efficient, 3600 W peak power Class D amplifier module with Power Factor Correction and extremely low AC consumption
  • Acoustic Linear Phase (ALP) design provides complementary coherence between QSC loudspeakers deployed in the same audio system delivering a uniform listening experience across the entire venue.
  • QSC SysNav™ (System Navigator) App allows the user to easily design, configure, control, monitor and apply signal processing to individual subwoofers, full arrays or groupings of both.
  • Network solution includes digital audio-over-IP (Dante®) for interoperability with other audio equipment and seamless control and monitoring integration into the Q-SYS Ecosystem via Q-SYS Inventory Extensions
  • Omni-directional or cardioid radiation modes (cardioid setup requires min. 2 units)
  • Selectable DEEP™ mode for extremely low frequency extension
  • Rugged wooden enclosure with Polyurea coating for lasting durability
  • Four low-noise, heavy-duty casters
  • Vertical or horizontal deployments (M20 threaded pole receivers) combined with array frame/ground-stack adapters or loudspeaker poles.
  • Complemented by LA108 and LA112 active line array loudspeakers
  • Industry-best global 6-Year Extended Warranty with product registration.

Good value for the money.
Color: Black, Size: 6 Panel
This partition package is a great value. I looked at many options and this one had long length to cover an entire room with the six partitions. The pieces went together easily, took about 30 minutes to assemble and has the needed Allen wrench included. It is stable with no fear of being easily knocked down. The black fabric does not completely hide everything and if there is a light on the inside, it can illuminate what is going on. It does the job but if you wanted complete privacy you would need thicker material. Overall it does what I need in that it make a TV room into a kind of guest room of sorts.

Worked amazing during christmas
Color: Black, Size: 6 Panel
We had a ton of people over for Christmas so I had to make an extra place for someone to sleep so I used these and surrounded an air mattress and made a small shelter basically. The dividers are light but sturdy , not heavy duty of course but not expected for this price. They do an excellent job of blocking out light and are not see thru and worked very well. Assembly was straight forward and even comes with an included wrench but I used my own to speed the process. 100% satisfied

Satisfactory
Color: Black, Size: 6 Panel
Everything was advertised. But the box it was shipped in was torn up pretty bad and taped up to compensate. Nevertheless, the product itself was not damaged.

Easy to use.
Color: Grey, Size: 6 Panel
These are easy to put together and to use. We have used them with all the panels. We have also used them broke down into 2 and 3 panels. They work well for blocking views. They don't block noise or help quiet the room being used, however. Only bad thing about them. We use them for our Auxiliary meetings.

Easy to assemble. Still used for over a year 🙌🏾
Color: White, Size: 6 Panel
Everything is perfect! I would buy again in other colors and heights if I need additional separation in the basement.
