The NEW 2009 EX-550i/25 “Transient Optimized”
crossover design
now available as an upgrade option.
The
EX-550i/25 is the latest in a line of CDT Audio "transient
optimized" crossovers. All the experience gained in
the design of this historic line of crossovers was applied
to the design of the 550i/25.
The lower crossover
frequency of 2.5kHz avoids dispersion and response anomalies
in the mid-woofer to tweeter transition seen when crossing
over at higher frequencies. This lower crossover frequency
provides superior blending in a range of installations and
with various drivers. Below the 2.5kHz crossover frequency
the tweeter is attenuated 24dB at 1.25kHz. This is at just
1/2 the crossover frequency. This rapid roll off is very
effective especially at this lower crossover frequency in
providing protection for the tweeter in high power systems.
A two position woofer response "crossover trim"
corrects response differences seen between a range of mid-woofers
from 4" to 6.5". Combine this with the 5 tweeter
level settings to get a smooth natural sound.
The response shape
which the crossover applies to the tweeter adds a touch
of EQ to restore energy to the normal power response roll-off
characteristic observed in virtually all tweeters. In the
550i/25 this is focused higher with a flatter response "approach"
than earlier models so only the 15kHz area is selectively
boosted.
The response
shape and user friendly adjustments were gleaned from working
with the line to produce this optimally effective 550i/25.
The result is an easy to install substantially universal
module that works extremely well. The 5 tweeter level steps
are larger than before and cover enough range to work in
virtually all installations.
This new xover design is specially designed fort M6 and
ES-06 and 06+ woofers but is available as a high-end musical
perfect defined and detail blend upgrade to any CDT woofer/tweeter
combo.
This is the silver bullet among our crossovers!
Test it and get a
smile that will last for ever!
