Octasound's SP810A is a full-fidelity (40 Hz - 20 kHz) central speaker system.  The SP810A tuned port enclosure contains an efficient 10" woofer matched to 4 compression horns & drivers.  The frequency spectrum of the woofer and horns is determined by an internal crossover network that is optimized to maximize performance.  This combination ensures full fidelity reproduction from an extremely compact central speaker system.

The SP810A is extremely sensitive with an SPL of 99 dB per watt at 1 M, hence very little amplifier power is required to obtain the required sound pressure levels.  At maximum RMS input power, the SP820A can produce 123 dB SPL at 1 M.

The SP810A can withstand input power of 250W RMS.  The SP810A also contains a built-in, self-resetting thermal protective circuit.  This protects the high frequency drivers from excessive and distorted (10% THD) input levels.

The SP810A provides coverage over 360° Horizontal & 180° Vertical plane.  These wide dispersion characteristics will permit a large area to be covered by a single SP820A.

The SP820A is only 10" (25.4 cm) high & weighs 44 lbs. (20 kg).  The SP820A can be installed in low ceiling areas and close to lights without casting shadows.  The low weight permits suspension using readily available hardware such as closed link chains, wire, rope, etc.  The combination of small dimensions and low weight permits the SP820A to be shipped inexpensively via standard couriers or parcel service companies.
