Hidden, the company behind the pop-up HiddenRadio speakers, presents the HiddenHUB-- a 360-degree speaker promising adaptive acoustic sound and smart features within a sleek design.

The HiddenHUB features interesting adaptive sound technology making use of an accelerometer to detect whether the speaker is on a flat surface or mounted on a wall. Meanwhile a combination of IR sensors and proprietary logic board scans the room housing the speaker and dynamically adjusts audio to fit the space.

The result, at least according to the company is "no more dead spots... you will always experience the perfect audio set up."

Harman presents a compact TV audio system at IFA 2015-- the JBL Boost TV, a soundbar the company says suits multiple TV sizes and features JBL Soundshift, a means for instant switching between TV and mobile device audio.

A Red Dot Award for product design winner, the Boost TV is all of 380mm long, with two bass ports at either end. It is covered in black fabric and carries a pair of 50mm transducers, 30W of digital amplification and onboard DSP with virtual surround and Dolby Digital decoding.

Logitech's Ultimate Ears announces the Boom 2-- a sequel to the popular Boom Bluetooth speaker featuring louder (by 25%, apparently) sound, longer wireless range and a completely waterproof design.

According to the company the Boom 2 has an IPX 7 rating, is drop-proof from up to 1.5m and has 30m wireless range. The battery also promises improvement, as it powers up to 15 hours of use on a single charge.

Tales of the audio cassette's death might be slightly exaggerated-- US-based National Audio Company is not only still alive and making cassettes, but sees the best sales since 1969.

According to Bloomberg the company produced over 10 million cassettes in 2014, and while 2015 sales growth clocks at 20%. Not too shabby for a supposedly dead medium.

NAC attributes such results to the retro movement, where younger audiences are dropping the digital convenience of MP3 in favour of the "warm" analogue sound of tape. Music tapes make 70% of NAC sales, with the rest being blank. NAC has deals with major record labels (such as Sony and Universal), as well as small contracts with indie bands.

Described by Canton as a "powerful home entertainment hub," the DM90.3 appears ideal for customers wanting a one-box solution complete with Dolby Digital and DTS decoding, amplification, 3D and 4K pass-through, and Bluetooth aptX streaming.

The soundbase portion of the DM90.3 carries 10 custom-made speakers-- 2 tweeters, 4 mid-range drivers and 4 subwoofers, with the option of adding an external subwoofer for extra bass.

Samsung announces 3 additions to the Wireless Audio 360 speaker lineup-- the R5, R3 and R1, all featuring "ring-radiator" technology from the egg-shaped R7 and a built-in tap-and-swipe user interface.
