Heco BellaDonna

They developed every component and every structural detail of the Bella Donna from scratch. Of course, this is all based on decades of experience. Naturally, using Heco tried and tested technology. It's just even better. Even more elaborate.
They have equipped the Bella Donna with a 200 mm diameter woofer chassis. This produces a cone surface area of 225 cm2. Heco developers had to utilize this surface area to move as much air as possible, i.e. to generate a good bass range. In doing so, however, they also had to ensure the Bella Donna's woofer reproduces vocals and instruments with the utmost precision. And precision means control. They achieved this with a newly developed cone. Of course, this is based on tried and tested kraft paper, which is made from selected Nordic softwood and consists of particularly long fibers. Combined with the wool threads inserted into the cone, it creates a fiber structure that makes our cones particularly sturdy. Nevertheless, they are still lightweight and easy to control - which is an important component for a precise sound.
While the woofer has to take on numerous tasks, they have also placed special demands on the tweeter. It takes over proceedings at the aforementioned 2,600 Hz, which is earlier than the majority of other two-way speakers. The silk compound dome measures a full 30 mm, making it the largest in Heco current portfolio. In addition, the bead that surrounds the dome also vibrates. This develops a radiating energy and level of dynamics that are clearly superior to other tweeters. Of course, tried-and-tested Fluktus baffle is also used here, the waves of which are precisely calculated to ensure optimum radiation across all frequencies.
The Bella Donna's housing isn't just a pleasure to look at, as it also ensures optimum technical conditions. The deviation from a simple cuboid shape ensures any standing waves inside the housing are nipped in the bud. Targeted struts make the already sturdy exterior panels, some of which are 25 mm thick, even more resistant to vibrations. This is also manifested in its weight. The high-end speakers, which measure approximately 28 cm wide by 45 cm tall, weigh in at 17.8 kilograms - and that's per speaker.
