About the Opus 1

The Wharfedale Opus 1 is a high-end 3-way floorstanding speaker designed with advanced materials and construction techniques. It features an 8-inch (200mm) Kevlar bass driver, a 3-inch (75mm) soft textile dome midrange driver, and a 1-inch (25mm) textile dome tweeter. The speaker has a nominal impedance of 6 ohms and a sensitivity of 89dB. It covers a frequency response of approximately 37Hz to 44kHz (+/-3dB), with a low frequency limit of 26Hz (-10dB). The recommended amplifier power is between 60 and 300 watts, with a maximum peak SPL of 109dB. The cabinet is constructed from 18 and 33mm MDF with real wood veneers finished in a deep gloss piano lacquer. The curved cabinet design, made from a composite of Australian eucalyptus and pine with synthetic resins, helps prevent standing waves and maintains bass energy. The speaker includes gold-plated tri-wire terminals and integral plinth stands with spikes for stability. The Opus 1 is noted for its dynamic, linear bass response and smooth tonal balance, making it suitable for serious audiophiles seeking a neutral yet powerful sound signature.
