PIEGA INTRODUCES ENTRY SPEAKER ACE
The Swiss loudspeaker manufacturer Piega is not exactly known for cheap transducers. Rather for quite expensive models with aluminum housings and exorbitantly complex foil drivers. With the new Ace series, consisting of a slim floor-standing model, a compact loudspeaker and a center, the Confederates also have delicious offers for normal wage earners in their range.
The Ace series was designed by the Swiss designer Stephan Hürlemann and is intended to replace the previous TMicro speaker series. In terms of materials, Piega remains true to itself: The housings of the Ace series are also made from an aluminum profile with no visible screws or seams. Modified dynamic drivers are used for the bass / midrange. High frequencies are emitted by an Air Motion Transformer AMT-1.
The very compact and slim speakers should offer a “surprisingly powerful, balanced and clear sound”. In combination with an active subwoofer, the compact Ace 30 should also be suitable for sound reinforcement in larger living spaces. The floor-standing model Ace 50, equipped with three three 120 mm chassis, is said to offer astonishing bass performance even without a subwoofer. With a round base plate that is offset from the housing, the slim Ace 50 is particularly living space-friendly.
The compact Ace Center is also available for expansion into a multi-channel system. Its two 120 mm MDS bass-midrange speakers and the AMT-1 tweeter are designed to guarantee excellent speech intelligibility when playing TV and feature films.
The Ace models are available in three housing designs. In addition to a silver-colored aluminum housing with silver covering, PIEGA offers the loudspeakers in a black anodized version with black fabric and painted white with white fabric covers for a small surcharge.

DENON EXPANDS HOME SERIES WITH A HEOS SOUNDBAR
With the Home Sound Bar 550 expanded Denon his “Home” product family with a soundbar optimized for TV sound. The bar speaker, equipped with six drivers, supports 3D surround sound in the formats Dolby Atmos and DTS: X. Using the HEOS system used by Denon, users can also play audio files from streaming services or local music libraries via the soundbar. It can also be integrated wirelessly as a separate zone in existing HEOS multiroom systems, for example with other Denon Home products. The Denon Home Sound Bar 550 will be available from February 2021 for 649 euros.

KEF PRESENTS NEW DRIVER TECHNOLOGY UNI-CORE AND SUBWOOFER KC62
Deep and powerful bass, which also sound clean and precise, is difficult to conjure up from small enclosures. It is not impossible, but it requires a lot of force and stroke. KEF introduced a new driver technology last week that is supposed to deliver exactly that: Uni-Core.
At first glance, these are just two back-to-back mounted woofers based on the force-canceling principle, such as those in the KEF Blade is used. The drivers support each other, which among other things reduces the transfer of kinetic energy to the housing. Only at second glance does Uni-Core’s unusual motor construction become apparent.
The double driver of the patent pending Uni-Core technology uses a common magnet system with two magnet gaps and concentrically arranged, overlapping voice coils. This means that the voice coils can take up the same space, move a good deal closer together and still produce a large diaphragm stroke. KEF promises extremely precise, powerful and deep reproduction from an unusually small housing.
A few days after the technology presentation, KEF also conjured up a first product with Uni-Core: the Subwoofer KC62. The bass cube, which is only about the size of a football (246 x 256 x 248 mm), but weighs 14 kg, uses a 2x 500W class D power amplifier to supply the motor with power. KEF specifies an incredible lower limit frequency of 11 Hz (-3 dB). That would be really sensational for a sub of this size. The maximum level is 105 dB.
To achieve this, however, further technical tricks apart from Uni-Core were required. KEF came up with a special shape for the bead (the flexible outer suspension of the membranes), which is said to be inspired by the Japanese origami folding technique. This bead, called “P-Flex Surround”, should enable particularly large and linear strokes and better withstand the acoustic pressure in the housing without reducing the sensitivity in the same way as is the case with conventional bead designs.
Powerful excursions. (The fact that the membrane seems to wobble is due to the so-called rolling shutter effect of the video recording.)
Even more: the KC62 contains a new sensorless “Smart Distortion Control Technology” for which a patent is pending. This form of negative feedback measures the current in the voice coil and detects and corrects non-linear distortions. The total harmonic distortion (THD) should be reduced by up to 75%. The signal is optimized by special DSP algorithms. Of course, this child also has a nice marketing name: The “Music Integrity Engine” prevents overloading and ensures precisely controlled relationships between all components involved.
The KC62 can be operated with all possible loudspeaker / amplifier combinations thanks to the LFE and line-level / loudspeaker-level inputs and also offers optional wireless control with KEF SmartConnect. The KC62 can be flexibly adapted to the installation location using five preset room correction curves that can be selected using a switch.
The subwoofer, available in “Carbon Black” or “Mineral White”, has a housing made of extruded aluminum and looks very modern with its smooth, rounded shapes and screwless look. And what does the fun cost? KEF will call 1,499 euros for the KC62 when it goes on sale in February.
– We are excited.
