Peerless 830984  2.5" Full Range
8 ohm
Black Aluminum cone

Features include: A Neodymium motor structure and double-venting system that helps keep dynamic range intact, as the transducer can handle more power and dissipate excess heat efficiently.  An anodized aluminum dome provides superior sound dispersion and off-axis response.  A semi-progressive surround reduces distortion, especially at high output through long excursion.  The drivers’ direct connected dome dust cap (connected to the magnet system voice coil) improves dispersion at high frequencies, providing superior sound on the high notes.  The inserted copper cap on the pole piece ensures control the system impedance, thereby extending the upper frequency range.
