REL Acoustics HT/1003 300 Watt Subwoofer Black

Our Price £449.00 RRP £559.00 Save: £110.00
The REL Acoustics HT/1003 300 Watt Subwoofer is a compact sub that remains big on performance, with a 10 inch carbon fibre driver for high excursion. With a Class D 300W amplifier, the HT/1003 sub has plenty of power for your home cinema system to bring you a cinematic experience.

The 10 inch driver of the REL HT/1003 subwoofer uses CarbonGlas to produce a lightweight yet extremely stiff cone. Tough carbonfibre is backed by lightweight glasfibre for a driver that performs with speed and dynamics, when compared to other models with slow and heavy cones. High quality butyl surrounds remain pliable and soft for years to come.

The REL HT/1003 uses a NextGen5 Class D amplifier to produce 300 Watts of high impact power. Freeing up interior space whilst running cool allows for greater cabinet volume to achieve ultra-deep bass. With specific inverse filtering on the input, the CarbonGlas driver is able to extend deeper.

The subwoofer cabinet is constructed of high grade line-grained composite, with a top surface of hand lacquered rubber, for a minimal, stylish look. The HT/1003 is Zero Compression Wireless compatible, with the HT-Air wireless system. Place your subwoofer anywhere in the room and enjoy powerful bass without cables.
