This range allows the subwoofer to reproduce both deep bass frequencies and somewhat higher frequencies with precision and clarity. The extension up to 500 Hz is particularly useful in home theater setups, where seamless integration with main speakers is required. For discerning listeners, this means that the subwoofer is capable of conveying both subtle bass nuances and powerful audio events with impact.

Welche Materialien wurden für den Membrankonus des Ultimax II UMII15-22 verwendet?

The Ultimax II UMII15-22 is equipped with a thick, one-piece Nomex honeycomb cone that has been additionally reinforced with high-performance fiberglass. This combination of materials ensures outstanding stiffness and minimizes distortion at high volumes. The Nomex honeycomb construction provides a structured surface that effectively controls resonances and self-movements. Especially at extreme volumes, where conventional cone materials might fail, this construction ensures that the subwoofer reproduces deep tones cleanly and precisely.

Wie ist die Bauweise der Schwingspule des Dayton Audio Ultimax II UMII15-22 gestaltet?

The Ultimax II UMII15-22 features dual 2-ohm copper voice coils that are wound in two layers. This construction ensures increased thermal resilience and offers a flexible wiring configuration. You can effortlessly implement the subwoofer in various audio installations. The voice coils with a diameter of 63.5 mm not only guarantee precise reproduction but also contribute to effective heat dissipation management, which is crucial during intense musical passages.

Welche Vorteile bieten die Belüftungsmerkmale des Ultimax II UMII15-22 Subwoofers?

The ventilation of the Ultimax II UMII15-22 includes a large ventilated pole piece as well as additional ventilation under the spider. This design optimizes heat management by efficiently dissipating the heat generated during intense use. Effective temperature control is crucial for preventing performance loss and maintaining sound quality. Especially when using the subwoofer in sealed or ventilated enclosures, the lifespan of the component is significantly extended by these ventilation features.

Welche Gehäuseoptionen gibt es für den Dayton Audio Ultimax II UMII15-22?
