Reference II 6.5" Bookshelf Speakers Walnut
Bookshelf speaker with 6.5" Cerametallic woofer and 1" titanium tweeter on a Tractrix® horn, delivering 44Hz–25kHz response, 94.5dB sensitivity, and 100W/400W power handling. Features rear-firing Tractrix® port in a braced MDF cabinet with dual binding posts for bi-wire/bi-amp, finished in walnut.
FEATURES:
The most versatile surround speaker available:
The RP-500SA II can be used as an up-firing immersive speaker for Dolby Atmos Technology, a height speaker, or a rear surround model — all with the flip of a switch. Immersive sound comes alive from all directions, including overhead, with these Dolby Atmos® enabled speakers. Add to any monitor or tower speaker, or use as surround speakers for a hemisphere of rich, detailed sound.
90° x 90° silicon composite hybrid Tractrix horn:
Horn loading maximises efficiency and increases detail while focusing high frequencies towards the listening area. Proprietary Tractrix® geometry provides the most efficient transfer of high-frequency waves into the listening area. The phase plug and compressed moulded silicon face ensure smooth frequency response. When combined, the cleanest, most natural sound possible is created. The second generation increases horn size for a larger soundstage and enhanced directivity.

Linear Travel Suspension (LTS) titanium diaphragm tweeter:
The exclusive Linear Travel Suspension minimises distortion for enhanced, detailed performance. LTS tweeters are a hallmark of previous Reference lines, making them a core component of some of the best speakers in the world.

Vented tweeter design:
The vented tweeter housing reduces standing waves that create unwanted harmonics, resulting in enhanced detail and clarity in high-frequency reproduction.

Cerametallic woofers – all-new design:
A signature feature on the Reference Premiere series, Cerametallic™ woofers are exceptionally rigid and lightweight for minimal distortion and maximum efficiency. New aluminium shorting rings reduce distortion as well as increase power handling, and the new motor structure improves transit response with more control, greater speed, and accuracy.

Tactrix Port:
Utilising Tractrix geometry, the Reference Premiere port allows for the most efficient, fastest air transfer from the cabinet, which reduces port noise for punchier low frequencies and cleaner, more powerful bass.

Bi-Wiring Bi-Amping Capability:
Dual input terminals for bi-wiring / bi-amping capabilities separate high and low-frequency current into different speaker cables, reducing distortion for clearer midrange. Bi-amping allows for further optimisation of performance with separate outboard power amplifiers for the high-frequency and low-frequency drivers.

Switchable crossover:
The RP-500SA II features a switchable crossover that changes between Atmos and Surround modes for optimised performance in any configuration.
New and improved input panel:
Featuring audiophile-grade wire and easily accessible aluminium binding posts for any connection type.
Furniture-grade materials and finishes:
Finishes include ebony vinyl and walnut vinyl that boast satin-painted baffles with a scratch-resistant finish.
Strong, flexible, removable grille:
Attaches magnetically for an elegant transition from powerful showstopper to discrete performance piece.
