McCauley Model 6174 Single 18" LF Transducer
The 6174 18" transducer is an ultra-high performance woofer designed to reproduce low and extended low frequency material at very high SPL's. The 6174's twin coupled magnet structures increase the power handling to 800w RMS / 1600w PROGRAM, while the system's convective cooling chambers actively dissapate heat. The 6174 offers over 2" of controlled, peak to peak cone excursion for exceptional performance, making it an ideal choice in high performance applications like touring class sound systems and theme park installations.
Features:
2" Peak to Peak Excursion - High excursion design allows this unit to outperform most other transducers in this class
Extreme Power Handling - Unique double-magnetics structure allows this unit to handle an enormous amount of power
Natural Fiber Ribbed Cone - This cone material demonstrate's high rigidity for tighter response
4" In Wound Voice Coil -
Able to dissipate heat quickly, this coil design actually strengthens under high-heat conditions
6000 Series Magnet Assembly - Standard magnet for all 6000 series drivers, this assembly can be interchanged among all standard 10", 12", 15" and 18" designs
Cast Aluminum Basket -
Durable and lightweight, this basket provides superior strength over weaker stamp-frame designs
Field Serviceable Basket Assembly - Allows 5-minute repairs in the field with only a simple allen wrench
InWound Voice Coils -
Thermally and geometrically stable, this design actually strengthens under high-heat conditions
Large Vent - Eliminates back-pressure and convectively cools the voice coil
Nickel Plated Brass Terminal Posts - Corrosion resistant posts enable quick and easy connections, up to 10 gauge speaker wire
One-Piece Backplate / Pole Piece - Eliminates shifting even under extreme conditions, and focuses maximum flux density for high efficiency
Twin Front side / Backside Gasket - Natural material gaskets are used on both the front and the back of the mounting diameter, to provide a tight and musical seal
