Description

Abaca Audio 6.5" High-End Woofer 8 ohm - AAW61B8

Composite speaker cone for less distortion and coloration and excellent damping characteristics
High loss rubber surround for long life and reduced reflected resonance peaks
High performance ferrite magnet
High power handling Kapton Voice coil former with heat-resistant SV wire
High density aluminum die-cast frame
Symmetric Motor Drive (SMD) technology
Designed and engineered in the USA

The design of AAW61B8 driver is based upon the benefit of an extended pole piece in a magnet system. Finite element analysis (FEA) simulation was also used to optimize the magnet structure and specifically to shape the pole piece to achieve symmetric flux distribution along travel path of the voice coil. This design provides better driving force linearity and it also considerably reduces VC inductance modulation and DC offset of the moving system at high power levels. The result is much less distortion and more effective VC cooling. The cone/surround design is optimized to achieve extended and balanced frequency response without apparent top end resonance. The back of the composite speaker cone (layered aluminum, foam, and fiber glass) is manually coated to maximize damping properties of the moving system. The massive aluminum die-cast frame has been developed to minimize parasitic structural resonances and dissipate VC heat rapidly.

AAW61B8 is a high performance driver with extended bass reproduction. This driver is an excellent performer even in bigger size cabinets so it can be used in top class floor-standing systems.

This woofer is a perfect match for the AAT418 Tweeter in a 2-way speaker cabinet.
