Crescendo Revolution 5S3 3-way speaker system

No. The Crescendo Revolution 5S3 is an active component system with no passive crossover included or required. Each driver receives its signal directly from a dedicated amplifier channel, with frequency division handled by an active DSP processor or active electronic crossover upstream. This is the design intent of the 5S3 and is what enables precise tuning capability that passive crossovers cannot provide.

A minimum of 6 amplifier channels is required for a stereo installation: 2 channels for the midbass pair, 2 channels for the midrange pair, and 2 channels for the tweeter pair. All three drivers in the system are 4 ohm nominal impedance. A 6-channel amplifier or a combination of amplifiers providing 6 total channels will work. Recommended power per channel is 50 to 100 watts RMS.

Any active DSP that provides at least 6 output channels with per-channel crossover control, time alignment, and equalization will work with the Crescendo Revolution 5S3. Audio Intensity recommends Goldhorn DSP units for this application. Goldhorn DSP processors provide the full active crossover management, time alignment, and equalization the 5S3 requires to perform at its design intent. Audio Intensity is the Original US Importer of Goldhorn DSP and can assist with configuration guidance for 5S3 installations.

Each driver in the system is rated at 50 to 100 watts RMS at 4 ohms. The 6.5 inch midbass, 4 inch midrange, and 28mm tweeter all share this rating. Total system power across all 6 channels runs from 300 to 600 watts RMS for a stereo pair. Amplifier selection should target 50 to 100 watts per channel for each driver type.

Crescendo does not publish recommended crossover points for the 5S3, as active installations are tuned to the specific vehicle and mounting locations. General starting points for a door-kick-sail 3-way layout are a midbass high-pass at 80-100 Hz and low-pass at 300-500 Hz, midrange band-pass at 300-500 Hz to 3-5 kHz, and tweeter high-pass at 3-5 kHz. Final crossover points should be set by measurement and listening in the actual installation. Use 24 dB per octave or steeper slopes on the tweeter high-pass.

The Crescendo Revolution 5S3 is a 3-way active system with 6.5 inch midbass, 4 inch midrange, and 28mm tweeter. It requires DSP and 6 amplifier channels. The Crescendo Revolution 5S2 is a 2-way system with 6.5 inch woofer and 28mm tweeter, and uses a passive crossover included with the set. The 5S3 is the appropriate choice for DSP-based active front stage builds where maximum tuning control is the priority. The 5S2 is the appropriate choice for simpler installations where passive operation is preferred.

Yes, provided the installation is properly designed and tuned. The active 3-way architecture requires more setup than a passive component set, but once a DSP is programmed for the vehicle, the 5S3 behaves as a daily driver in terms of durability and ease of use. The DSP tuning is a one-time process; after configuration, the system operates transparently. Daily listening at moderate levels is well within the driver ratings.

The Crescendo Revolution 5S3 carries a 1-year limited warranty against defects in materials and workmanship when purchased from an authorized Crescendo dealer.
