Yesterday we covered a couple of nice audio-related deals which included a Marshall Bluetooth speaker for just $130 and the Denon 7.2 1700H AVR for under $500. The AVR discount ends in less than a day as it is limited time offer.
For those who want deeper bass than what the Marshall portable speaker offers but don"t want to go for an AVR-like setup, the Polk Audio Signa S4 offers a nice middle ground. The system is currently a great deal thanks to Amazon Early Spring sales as it is up for sale at just $356 (purchase link under the specs table down below).
The big draw here is Dolby Atmos at this price range in an all-in-one soundbar system like this. Dialogue delivery is handled by the dedicated center channel and Polk’s in-house VoiceAdjust tech is said to help you raise the speech levels without cranking the rest of the soundtrack. That can be especially handy when action scenes drown out conversations, in movies like Tenet.
Speaking of sound processing technologies, BassAdjust is there to ensure that the near 6-inch wireless subwoofer blends smoothly with the bar so that mid-bass does not get overbearing. The technical specifications of the Polk Audio Signa S4 are given in the table below:
