Wiring
What makes “Ribbon” tweeters better than” Dome” tweeters?
Ribbon tweeters use a very low mass metallic ribbon to reproduce faster, more sparkling
highs. Dome tweeters use the same type of voice coil as regular speakers.
Don’t “Ribbon” tweeters have lower impedance than 4 Ohms?
Because “Ribbons” do not use a voice coil they do have lower impedance than dome
tweeters. This is corrected by a built-in impedance matching transformer that gives them a
constant 4 Ohm impedance.
The frequency response claims 3,000 Hz to 40,000 Hz. Is that real?
Yes. The human ear cannot hear sounds above 20,000 Hz, but it can perceive harmonics
well above that. Ribbon tweeters are known for exhibiting extremely wide frequency
response.
Why is the Crossover network needed? Can’t I just connect the ribbon tweeters
directly to my speaker wires?
The Crossover network protects the Ribbon tweeters from being damaged by low
frequencies. This permits the Ribbons to play at higher volume settings.
One of my VRT18 Ribbon tweeters is not producing any sound. What should I do?
Call Technical Service (1-800-445-1797) for assistance.
Recommended Method For Splicing Wires
#1
Strip 1/2" of insulation from the ends of the wires.
#2 #3
Twist together and bend as shown. Wrap with electrical tape.
Mounting
Flat Surface Mount
1. Attach the flat surface mount
brackets to the Ribbon tweeters using
the supplied screws.
2. Attach the brackets to the selected
location using the supplied screws.
3. Route the wires to the Crossover
network and connect them by pushing
down on the Quick release terminals
and inserting the wires into the holes.
Release the terminal to secure the
wire.
Angled Surface Mount
1. Attach the angled surface mount
brackets to the Ribbon tweeters
using the supplied screws
2. Attach the brackets to the
selected location using the supplied
screws.
3. Route the wires to the Crossover
network and connect them by
pushing down on the Quick release
terminals and inserting the wires
into the holes. Release the terminal
to secure the wire.
If you are installing the VRT18 Ribbon speakers to upgrade/replace your
existing speakers, mark the polarity of the speaker wires, disconnect the
speaker wires and remove the existing speakers from your vehicle.
Temporarily place the VRT18 Ribbon speakers in the location you selected in
your vehicle and connect the existing speaker wires. Temporary placement of
the speakers in the vehicle helps in estimating length of wiring needed, as
well as, how the speakers will sound in various locations of the vehicle.
We understand that automotive audio equipment installations can be
troublesome at times, even to the most experienced of installation
technicians. If you are not confident working with electrical wiring, removing
and reinstalling interior panels, carpeting, dashboards or other components
of your vehicle, please call our TOLL FREE help line (800)445-1797 and our
in-house technical service team will answer your installation questions.
