Polk's newest soundbar is the Signa S4 ($399) and it is coming soon. This soundbar is the first from the company to offer Dolby Atmos, in this case, 3.1.2 sound using up-firing speakers. Additionally, it has the ability to upmix standard surround-sound to virtual 3D immersive audio.
"The Signa S4 sound bar’s advanced seven speaker array was designed to deliver a lifelike Dolby Atmos 3.1.2 listening experience. Its dedicated center channel provides crystal clear dialogue and its optimized left and right tweeters and woofers deliver a huge, wide sound stage. Plus, dual, up-firing speakers take advantage of Atmos’ height channels to send sounds over your head, rounding out your 3D sound immersion."Polk Audio
This is a fairly large soundbar, measuring 41.2" x 3.7" x 2.4", the compact wireless sub measures a mere 7.9" x 12.9" x 11.0”. There are seven total drivers on the soundbar itself, and one HDMI input with eARC capability, one optical input, an analog 3.5mm input, and a USB port for firmware updates.
Get great sound and Dolby Atmos for only $400 from a company known for providing great value in sound, Polk.
