Active Q Control
The Gryphon Q Controller is an innovative room-adaptive device that allows user adjustment of the total system resonance frequency and of system Q for ideal coupling to any room.
As a theoretical concept, active Q control was discussed in papers published in the 1950’s by Linkwitz and Greiner, but never successfully implemented prior to the breakthrough Gryphon Cantata stand-mount loudspeaker in 2002, offering powerful new opportunities for extensive low-frequency adjustment and room integration.
Subsequent Gryphon floor-standing models – Poseidon (2004), Trident (2005), Pendragon (2013) and Trident II (2013) have all incorporated active Q control as well as built-in Gryphon power amplification for the bass section.
Unlike compromised, universal external amplifiers, purpose-built, on-board Gryphon bass amps are conceived and built exclusively for optimal integration with our custom-built drive units, advanced crossover networks, handmade crossover components, non-resonant enclosures and proprietary, user-adjustable room integration parameters. This extraordinary degree of integration delivers a level of performance unattainable via any standard mix-and-match approach.
At the critical interface between amplification and loudspeaker, amplifiers are typically designed to ensure compatibility with the widest possible number of loudspeakers for obvious commercial reasons. And loudspeakers are designed for similar “universality.”
Inevitably, there are factors which can make specific pairings less than optimal or even untenable: radical differences in tonality, low-power amp vs. low-sensitivity speakers, low current amp vs. low-impedance speakers, etc.
As one of the very few High End manufacturers of complete system solutions from source components to amplification to loudspeakers, Gryphon has a uniquely valuable perspective on all relevant compatibility/synergy issues.
In order to elegantly and effectively resolve the electrical, mechanical and acoustical problems which plague lesser systems, the Gryphon Kodo incorporate a semi-active configuration with specially developed bass amplification. For extended headroom, available peak power is approximately 4,000 Watts or 4.5 horsepower. The dedicated, on-board Gryphon bass power amplifier weighs in at 70 kg per speaker!
Gryphon bass amps incorporate custom developed parts, the finest Sanken high current bipolar output transistors, linear power supply, large capacitor banks, DC servo-coupling, military spec. double-sided printed circuit boards and Holmgren toroidal transformers with internal magnetic shielding. Ultra-wide bandwidth and zero negative feedback contribute to extreme speed and unconditional stability.
In short, they are true, no-compromise Gryphon power amplifiers born for one purpose only, to be a perfect match for the speaker’s bass drivers, electronics and cabinet volume to an extent unrivalled by any conventional passive loudspeaker using external amplification.
