Tymphany NE85W-04 2-1/2" Full Range Woofer

Tymphany's NE Series full-range drivers feature an innovative sculpted, open cast aluminum basket design that minimizes internal acoustic reflections and acts as the neodymium motor's heatsink. The cone is aluminum, with a butyl rubber surround designed by finite element analysis for linearity of performance. FEA techniques also contribute to the motor's copper cap, which reduces inductance and extends high frequency performance.

Tymphany NE85W-04 2-1/2" Full Range Woofer
Tymphany NE85W-04 2-1/2" Full Range Woofer is rated 3.5 out of 5 by 2.
Rated 3 out of 5 by from High/Low distortionJust tested this driver with SoundEasy and a new high dynamic range microphone I made following Linkwitz's recommendation. Distortion tested at at 2.83V and 8V RMS is moderately high (3-10%) below 200-1,200 Hz and remarkably low above 1,200 Hz (0.1-0.2%). So it would make a great upper midrange but not so good as a woofer. Did not test below 200Hz.

Rated 4 out of 5 by from Small, high quality...loud!Cast basket, quality construction.I initially purchased these as replacement dash speakers for my BMW X5, but they are too deep won't fit, so I installed these as replacements in my JVC bookshelf system, could have used the next size larger, but oh well...These little things have brought new life into my 12 yr old 25w x 2 system. Very clear, loud, and surprising amount of bass. Glad I got them.
