REL Strata III Subwoofer - Black

Strata is designed as a closed box system. For its cabinet volume and drive unit, this offers the best compromise between extension and power handling. With smaller cabinets, such as Strata, the addition of a port to make it a reflex design can result in excessive port noise heard as chuffing sounds on very low frequencies, such as organ pedal notes. The cabinet is manufactured from 30 mm thick MDF (Medium Density Fibreboard). This is the material of choice where the very highest quality is demanded. There can be no substitute for weight and density as far as low frequencies are concerned.
For maximum performance we believe the electronics, cabinet and the drive unit should all be designed to work together.
All REL amplifiers are fully DC coupled to avoid phase shifts and compromises in their low end performance. The line level and filter stages are fully regulated to ensure total isolation from the power amp stages. The filter stages are unique designs using the highest quality components. The capacitors are high quality nitrogen filled polystyrene types of 1% very close tolerance and an indefinite life. The use of very close tolerance components also ensures consistency of performance throughout the production life of each model.
Great care is taken over the star earthing to maximise sound quality. There is further filtering of the higher frequencies to ensure optimum performance at all settings of the ABC. The built-in power amplifier is built onto a separate circuit board and uses ultra rugged audio grade MOSFET output devices. The power supply is the engine house of the amplifier, the smoothing capacitors are long life with very low equivalent series resistance (ESR), the bridge rectifier is very conservatively rated at 35 Amps. The transformers are ultra quiet audio quality toroid’s with very low losses, these are especially manufactured to our strict specifications. Great care has been taken to deliberately over engineer all REL products to ensure ruggedness in service. This ensures an exceptionally robust, long lasting device.
