Audio Development W40

AD W40 mid-woofer diameter 100mm made of glass fiber, rubber and ferrite.
External diameter, including fins: 123mm
Mounting hole diameter: 93.5mm
Installation depth: 48mm

CONE: Fibreglass with rubber suspension.
- VOICE COIL: Pure copper wire on aluminium former (26 mm diameter).
- BASKET: PPO chassis injected with fibreglass, in order to low down undesired distortions.
- DUST COVER: ABS, glued directly to the V/C former, with calibrated weight and dimensions in order to reach the desired Mms.

The 100mm midwoofer of AD is the answer for the request of such a small diameter woofer; very extended and with an excellent control, it grants the reproduction of the medium-lows in a very correct and realistic way.
Phase and impedance curves are measured after 20 hours burn-in at 20 W RMS, so are the T / S parameters.
