STAMPEDE AND STRATA 5
Stampede and Strata 5 are designed as closed box systems. For their cabinet volume and drive unit, this arrangement offers the best compromise between extension and power handling. With smaller cabinets, the addition of a port to make it a reflex design can result in excessive port noise, which manifests itself as ‘chuffing’ when very low frequencies, such as organ pedal notes, are reproduced. Worse, a small cabinet will not extend down as deeply as its closed box alternative.
The cabinets are manufactured from 30 mm thick MDF (Medium Density Fibreboard). This is the material of choice when the very highest quality is demanded. There can be no substitute for weight and density in the quest for accurate low frequency reproduction.
Stampede and Strata 5 offer microprocessor control of all functions, either via the remote control or the encoder on the front control panel. Remote control makes it easier for the user to
For optimum 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 performance. The line level and filter stages are fully regulated to ensure total isolation from the power amp stages. The filter stages are unique, bespoke designs which utilise the highest quality components. The capacitors are high quality nitrogen filled polystyrene types of 1% very close tolerance and indefinite life. The use of very close tolerance components also ensures consistency of performance throughout the life of each model. Although digital control is used, the audio signals only pass through analog circuits, thus ensuring no digital hash is added to the signal.
Great care is taken to
There is further filtering of the higher frequencies to ensure optimum performance at all settings of the ABC (Active Bass Controller). The
