Resonance 2-way 

pedal division speaker  

shown without grill

Resonance is a speaker range specifically designed to reproduce the ranks in the pedal division with power and character.   These designs are applicable for instruments  that can provide dedicated outputs for the pedal division or for individual pedal ranks.  Resonance is an excellent choice for adding digital ranks to a pipe organ installation. 

The R-15 system (shown in picture) includes a 15"  500 watt high compliance woofer and a 6"  75 watt mid range driver in a specialized tuned and voiced enclosure.  The R-10 (see picture below) includes two 10" 300 watt high compliance woofers and a pair of 5" 60 watt mid range drivers. These systems use a passive crossover for the 6" mid range driver,  but the woofers connects directly to the amplifier to accommodate the maximum damping available from the circuit. Heavy gauge wire(12 or 10 ga.) is highly recommended. These combined elements improve the speech and release for all organ tones. The larger wooden enclosures use the LDAC (low diffraction acoustically coupled) venting system to reveal all the color and texture of the voices.  The systems designed to fit into tight places use a manifold venting scheme that maintains a smooth response through each octave.


Two of the R15 enclosures above were built for a 400 seat church.  The R10S and R210S shown here are dual channel systems for home installations.
