Description
The Reiss RS-RX12 ULTRA is an uncompromising 30 cm (12-inch) subwoofer, designed for audio systems where raw power, endurance, and bass presence are paramount. With 1200W RMS power and up to 2400W peak, this speaker is built to handle extremely high loads without loss of control; ideal for powerful urban installations, demanding SPL systems, and extreme daily setups.
The RS-RX12 ULTRA is available in D2 (2 x 2 ohms) and D4 (2 x 4 ohms) configurations, offering great wiring flexibility and easy compatibility with a wide range of amplifiers, from high-power monoblocks to multi-amplifier systems. Regardless of the version, this speaker delivers powerful and punchy bass, with a distinct character and striking physical impact.
Designed to withstand extreme loads
The design clearly focuses on durability and stability under high power. The robust 7.6 cm (3-inch) voice coil is designed for high thermal resistance and extended operation, while the large 183 mm ferrite magnet generates a powerful and stable magnetic field for precise control of the substantial moving mass.
Thanks to its low Vas value, the RS-RX12 ULTRA is perfectly suited for compact enclosures, while its massive cone ensures deep, dense, and powerful bass reproduction. This speaker prioritizes pressure, weight, and endurance over speed and lightness – an essential characteristic of an ULTRA speaker.
For serious bass installations
With its robust construction, considerable weight, and deep motor, the RS-RX12 ULTRA is a subwoofer that commands respect, both during installation and in use. It is ideal for systems where the amplifier, power supply, and enclosure design are of as high a standard as the speaker itself.
The Reiss RS-RX12 ULTRA D2 is the ideal choice for those seeking massive power handling, powerful low-frequency response, and a speaker designed to be pushed to its limits with a 2x2Ω dual voice coil configuration.
