Lambda SeriesApollo Upgrade Option
The Acoustic Elegance Apollo Driver classifications can be somewhat confusing. First we should note that ANY AE driver except for the Dipole Line can include an Apollo Upgrade. So what is an Apollo upgrade?
The Apollo upgrade is simply the ultimate AE driver! The already super advanced motor design is taken a major step further with the use of additional dual Aluminum Faraday Rings that sit on the *outside* of the voice coil working in conjunction with the large copper ring inside the voice coil. There are very few companies using even a single Faraday ring, here is a driver with 3 large ones!
These additional dual rings perform two important functions:
(1)They raise the "real" thermal power handling of the driver. The upper ring is solid billet aircraft aluminum, 6" in diameter and 1/2" thick, that wicks the heat from the voice coil and the into the large cast aluminum basket giving tremendous thermal reserve. The inner ring is nearly 1/4" thick. The Apollo upgrade adds nearly 2 lbs of aluminum heatsinking to the drivers!
(2)Both rings act to further linearize inductance, or in other words lower the reactance of the woofer. This causes the voice coil to act nearly as an air core throughout its entire range of travel. This further improves the transient response and upper bass sound quality of the woofer.
All of the parts in this motor assembly are machined by hand and assembled to a tolerance equivalent to the thickness of a human hair (0.003") These tight tolerances assure that the extraordinary heatsinking ability will be most effective.
Rebuilds of the Apollo Drivers are the same low cost as regular AE Drivers, so they have an excellent long term value. If you are considering buying your *last* set of speakers, then look no further!
