The HERA 150 speaker is the technical evolution of the HERA 100 model, which has been available at BOULANGER for over 5 years. This latest version significantly improves the listening experience by using a new woofer that provides better bass extension. The soundstage becomes wider and more realistic. From a physical standpoint, the model is now available in two different versions: the Walnut finish (black front panel and Walnut sides) and the more discreet black finish (all black).

The HERA 150 is equipped with 3 speakers:

  • A 16.5 cm diameter woofer made of treated and damped cellulose pulp, topped with a powerful magnetic motor. It has a decompressed 37 mm diameter core for fast and authoritative bass reproduction.
  • A 16.5 cm diameter midrange speaker made of woven fiberglass, ensuring a beautiful openness and detailed, precise vocals.
  • A 25 mm soft dome tweeter with a 25 mm voice coil, providing extended high-frequency response without becoming aggressive.

We recommend placing your speakers directly on the floor. The provided isolation spikes should be screwed in to ensure good stability of the entire setup. They help eliminate the transmission of low-frequency vibrations to the floor.

For stereo listening, we recommend positioning your speakers symmetrically relative to the listening area. They can be slightly angled towards the listener.

We recommend a distance of at least 3 meters between the speakers to achieve a wide soundstage. Position your speakers without placing them directly against the wall (about 30 cm away). The front-facing bass reflex port allows for a relatively constant bass response regardless of the placement in the room.
