Transducer Specification Sheet
Model Number: P830984
Description: 2 1/2" Full Range
Revision: rev 2_1
Date: 20-May-09
Peerless Lifestyle full range drivers set the standard for quality audio in products including flat
panel televisions and sound bars, MP3 and cell phone docking stations, and multimedia PCs. With
their high power handling, smooth, even dispersion and low distortion, the Peerless full range
drivers can be paired with the Tymphany LAT250 for great bass performance.
Features include: A Neodymium motor structure and doubleventing 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 semiprogressive 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 cupper cap on the pole piece ensures control the system impedance, thereby
extending the upper frequency range.
