Polk's latest sound bar, the MagniFi Max, offers up a slew of connectivity and the ability to incorporate rear speakers to become a 5.1 system.

The sound bar comes with rear speakers for $599 (MagniFi Max SR) or without for $499, the audio company announced today. The SR-1 rears are also available as an upgrade for $125. Both versions incorporate a wireless 8-inch ported sub and feature a low profile 2-inch 'bar.

The sound bar comes with plenty of sound processing tricks including the company's own Stereo Dimensional Array technology which is designed to give the user an ultrawide sound stage. It also comes with Voice Adjust for clearer dialog and from what we've seen on other Polk models it should work rather well.

The kit includes three built-In Ultra HD 4K HDMI (HDCP 2.2) inputs, one HDMI (ARC) output, an optical input for TV audio, aux 3.5mm, Bluetooth and Ethernet.

The sound bar is one of several from the company we've seen that eschews DTS Play-Fi in favor of having Google's Chromecast built-in. Polk was one of the first partners for DTS' multiroom technology, though it still has models that support it, such as the Polk SB1 Plus.

We've been impressed with Polk's latest sound bars, particularly the $199 Signa S1 and $270 Polk MagniFi Mini ($299 at Crutchfield), so we're keen to see how the MagniFi Max performs.

The two versions of the MagniFi Max will be available in the US in August. UK and Australian availability yet to be announced. Expect the UK prices to be similar figures, just in pounds, while Australian pricing is likely to be over AU$1,000 each.
