The new esprit subwoofers really come into play when space is scarce but the desire for rich bass sound is at the top of the list. Although the black fiberglass coating on the outside is the only thing that makes them look different to their predecessors, what is on the inside is completely new. Dual voice coils with an impedance of 2 x 2 Ohms predestine them for use in compact, sealed enclosures with the best in impulse response. Their extremely flat structural shape allows for forms never dreamed of before for the enclosure design.
Features
- 2 x 2 Ohms dual voice coil for more flexible speaker configurations
- Extremely stiff honeycomb membrane with fiberglass coating
- Massive and rigid aluminum diecast basket
- Very low mounting depth for shallow subwoofer constructions
- Massive gold-plated terminals
- Wide rubber surround for maximum cone excursions
- T/S parameters optimised for use in compact sealed enclosures
