Aries Cerat Contendo Reference

Pulsus - bass module amplifier

Cypriot valve audio and hornspeaker house Aries Cerat bows their flagship Contendo Reference with horn-loaded custom Raal ribbon tweeter. A 4" compression Titanium midrange is loaded into a 350Hz Tractrix horn to cover 700 - 3.000Hz. Its horn flare terminates in a solid wood bullet enclosure to eliminate edge reflections. 118dB efficiency is attenuated to the 104dB system value with impedance-matching transformers. The round Tractrix midbass horn covers 110 - 700Hz with an 8-inch driver of just 13g of moving mass and also terminates in a massive wooden bullet enclosure.
The external 2 x 15" sealed bass bins are driven from the external Pulsus bass amp which combines a 6C19P tube stage in transformer-coupled parafeed mode with 2 x 400w class D amplifiers with SMPS. External 3-way crossovers handle the horn module.
