Does the SL2500 tweeter ULV magnetic fluid ever dry up?
My tweets are now 11 years old. They don't sound quite
as nice as either the SL2000 or the SL3000. Are they at
all perishable strictly due to age?
Featured in the Monitor 4.6, 5jr+, 5, 7, 10 and 12, the SL2500 tweeter makes a major contribution to the improved performance of the Monitor Series 2. Sharing much of the technology of the incomparable SL3000 tweeter used in the Polk flagship SRS series, the SL2500 is a highly refined, technically advanced driver.
The voice coil, wound around an aluminum voice coil former, is cooled by an exotic ULV (ultra-low viscocity) magnetic fluid. This material, which has a viscocity close to that of water, enables the SL2500 to exceed normal listening levels without loss of performance or reliability. The resulting dynamic range is dramatic, indeed unique for speakers in this price range.
