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

Strip 1/2" of insulation from the ends of the wires.

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.

Possible Mounting Locations
