​The company has unleashed a slew of new soundbars, subwoofers and Bravia TVs.  

​Sony already has a robust collection of soundbars in its Bravia Theater lineup. Today, the company is adding two more, as well as new rear speakers and three new subwoofers. The Bar 7 will sit in Sony’s premium tier, alongside the existing (and larger) Bar 8 and Bar 9 models, while the Bar 5 will offer a more compact and more affordable solution just below the current Bar 6.The Bravia Theater Bar 7 utilizes nine total drivers to produce Dolby Atmos, DTS:X and IMAX Enhanced sound. More specifically, that arrangement includes three woofers, two tweeters, two up-firing units and two side-firing drivers, in addition to four passive radiators. Compare that to the Bar 8 and Bar 9 which house 11 speakers and 13 speakers respectively. Sony says the Bar 7 has new two-way front speakers and the center, up-firing and side-firing drivers all have the company’s oval-shaped X-Balanced design. In terms of features, you get Sony’s 360 Spatial Sound Mapping and Sound Field Optimization for more immersive audio performance. The Bar 7 will come bundled with Sony’s new Bravia Theater Sub 7 for $870, but you can also purchase it without the subwoofer (pricing TBA). For a more robust system, the Bar 7 can be paired with the company’s Bravia Theater Rear speakers. Sony Bravia Theater Sub 7SonySpeaking of subwoofers, Sony debuted three new models today. The aforementioned Sub 7 is the smallest, employing a 5.1-inch driver for the low-end tone. Move up to the new Sub 8 and you get a 7.9-inch driver for “enhanced atmosphere, clearer bass,” according to the company. The largest of the new options is the Sub 9 which has two opposing 7.9-inch drivers for “powerful, clean bass.” Unfortunately, these add-ons don’t come cheap: the Sub 7 is $330, the Sub 8 is $500 and the Sub 9 is $900. Sony also touts dual subwoofer connectivity as part of the refreshed Bravia Theater lineup. All three of the new subs can be used as a pair, so long as you have a Theater Bar 7, Theater Bar 8 or Theater Bar 9. You can also use two subwoofers with some of Sony’s receivers (STR-AZ7000ES, STR-AZ5000ES, STR-AZ3000ES, STR-AZ1000ES and STR-AN1000). The company explains that opting for two subs provides “stronger, more balanced bass,” obviously, that fills the room for a more “cinematic effect.” Sony also says two subwoofers enable “richer, fuller bass” at lower volumes. Rear speakers are something you’ll need if you truly want immersive audio, and the new Theater Rear 9 units are a big upgrade over the current Rear 8s. Most notably, you get an up-firing driver for enhanced overhead sounds along with two passive radiators, in addition to a tweeter and a woofer. The drivers all have aluminum diaphragms instead of paper, and the Rear 9s come with a swivel wall mounts that enable 60-degree movement. A pair of Theater Rear 9 speakers will set you back $750.
