SB15NBAC30-4 5" Black Aluminum Cone Mid-bass
The SB Acoustics SB15NBAC30-4 is a powerful 5’’ midwoofer with a vented chassis that provides optimum strength and allows low compression. Its geometrically reinforced aluminum cone gives it an optimum piston operation and a reduced break-up.
Highlights
- Vented cast aluminum chassis for optimum strength and low compression
- Geometrically reinforced aluminum cone for optimum piston operation and reduced break-up
- Soft low damping rubber surround for improved transient response
- Non-conducting fiber glass voice coil former for minimum damping
- Extended copper sleeve on pole piece for low inductance and low distortion
- CCAW voice coil for reduced moving mass
- Long life silver lead wires
- Vented pole piece for reduced compression
