low pass sums to a fourth order Linkwitz-Riley. The
Tweeter Crossover Network is a second order design; how-
ever, this acoustically sums to a fourth order Linkwitz-
Riley high pass. Refer to figure 7. All these acoustic Fourth
Order designs keep the speakers operating within their opti-
mum frequency range while offering the best blending of
each speaker. All network inductors are air core designs; so
they will not add distortion. All network capacitors are film
type for extra reliability. All the Capacitors and Inductors
are chosen for high current capacity. Each section of the
network utilizes it own self resetting high current PTC type
fuses to provide an extra measure of protection.
Performance Features
• High Temperature Neodymium-Iron-Boron Alloy
Magnets
The 6 twelve inch Woofers, 64 four inch Midranges and 40
three-quarter inch Dome Tweeters all use this Alloy. The
Neodymium-Iron-Boron Alloy has the highest flux density
per unit of volume and helps to keep the Loudspeaker Sys-
tem weight to a minimum while preserving the utmost in
performance.
• Shielded Magnetic Field
The XRT2K may also be used in Home Theater Installa-
tions near a television receiver or monitor without causing
the television image to degrade. By design, all of the speak-
ers’ magnetic structures are inherently shielded which pre-
vents interference.
• Low Harmonic and Intermodulation Distortion
The XRT2K Loudspeaker System is capable of reproducing
the full dynamic range of a symphony orchestra including
pipe organ without audible distortion of any kind.
• High Power Handling
The Loudspeaker Elements and Crossover Components of
the XRT2K are all chosen for use with powerful amplifiers
up to 2,000 watts.
• Superior Imaging
Locating the Column of Tweeters between the two Columns
of Midranges generates a symmetrical horizontal polar
response for superior imaging.
•
Versatile Operation and Placement
In additional to the regular connections, the XRT2K Loud-
speaker System provides separate connections for Bi-Am-
plification and Tri-Amplification hookups, as well as Bi-
Wiring and Tri-Wiring.
• • • • • Extruded and Machined Side Panels and Column
The sides of the XRT2K Low Frequency enclosures and the
Midrange/Tweeter Column enclosure are machined from
extruded thick aluminum panels to be non-parallel and are
given a High Gloss Black Piano Type Finish.
•
Gold Plated Input Connectors
The XRT2K input connectors are gold plated for superior
corrosion resistance and high electrical conductivity.
