The Osborn Grand Monument loudspeaker is a flagship model designed without compromise to achieve perfect sound quality. It stands 1.62 meters high and weighs 175 kg each. It projects a stunning, life-sized, three-dimensional soundstage with realistic dynamics, scale, and authority, providing the listener with the best seat in the house for every performance. It has been rated by International Audio Review in the USA as 'unsurpassed by any other speaker, at any price, and the first speaker ever to gain an A1+ rating.' The speaker uses premium Focal drivers, including 12" Focal 'W' cone woofers, a 5.5" Focal 'W' cone midrange driver with a cast aluminum basket, and a 1" soft-dome SEAS tweeter. The frequency response extends down to 15 Hz. The cabinet features heavy lead lining and acoustic felt layers for an inert, box-within-a-box construction, resulting in exceptional transient performance and intimate musical detail. The design philosophy emphasizes simplicity and musicality, with only two key drivers mounted closely together to act like a large two-way mini-monitor, achieving high efficiency (92 dB), moderate impedance (5 ohms minimum), and high power handling (recommended max power 120 watts RMS). The Grand Monument is considered among the easiest large speakers to drive and sonically surpasses many other 'ultimate statement' large speakers in its price range. It is finished in high-quality veneers such as Gloss Bubinga, Gloss Redgum, or Gloss Spotted Gum. The This model is highly regarded for its integrated, focused sound and ability to reproduce music with scale and accuracy across the entire spectrum.
