Thanks for choosing

Velocity!

Congratulations on your purchase of your new

Velocity

product! We have invested tremendous eﬀort

in the de-sign process of the new

Velocity

subwoofer series, in order to achieve superior musical

performance.

For maximum performance and reliability we highly recommend that your new

Velocity

subwoofers

be installed by an authorised Velocity dealer. By using our

Velocity

line component speakers and

ampliﬁers you can be as-sured of making the best out of your high-quality audio hi-ﬁ system without

spoiling the sound by using com-ponents of inferior quality.

For additional information on the

Velocity

Product Line (technical data, user notes and soon also a

simulation programme for subwoofer housings) visit our Internet site at: http://www.velocity.de.

NEW COMPONENT FEATURES

High Power handling

Incredibly ﬂexible installation: The new

Velocity

subwoofers perform well in sealed, vented and

bandpass boxes.

Due to the low resonance values, the new

Velocity

subwoofers also work well in inﬁnite baﬄe

installations in which the woofer is mounted on the rear deck, using the trunk of the car for its acoustical

enclosure.

New ultra-linear long-throw suspension.

Corrugated mica polypropylene design yields tremendous rigidity.

Additional loudness is achieved through longer cone travel, so we designed the

Velocity

subwoofers-

with 6 to 9 mm peak-to-peak excursion.

The new reinforced spider renders spider tears a thing of the past.

Butyl rubber surrounds oﬀer linear cone movement without compression or the risk of tearing from

over-excursion even for longer cone travel.

New strontium ceramic ferrite magnets yield smaller magnet sizes without reduced magnet strength

but retain their magnet power far beyond the expected life of the woofer.

Four layers of high-temperature wire on DuPont Kapton Polyamide voice coil bobbins allow for voice

coil temperatures exceeding nearly 225 degrees Celsius without damage.

Rear vented T-yokes allow fresh air to move in from behind the woofer to cool the voice coil.

Safety precautions

Before starting to mount your speakers, please read carefully the instructions on installation and

connection.

Disconnect the negative terminal of the battery before carrying out installation and connection work.

Observe the vehicle manufacturer’s safety instructions (regarding airbags, alarm systems, trip

computers, vehicle immobilisers).

When drilling holes, take care to avoid damage to vehicle components (battery, cables, fuse boxes).

Do not mount the subwoofer onto ﬂexible rear decks (hatchback vehicles) or anywhere where they may

fall for-ward.

DUAL VOICE COIL ADVANTAGES

The dual voice coil woofer is actually quite old in the home audio industry but still relatively new to the

car audio world. The largest advantage of the DVC woofer is in the ﬂexibility in installation. In order to

raise the sound pressure level (loudness) in a car, you can either add more speakers or add more

ampliﬁer power to drive a single speaker. Many cars cannot ﬁt two subwoofers and their necessary

enclosure volumes but can easily ﬁt large power ampliﬁers and a single woofer. Simply speaking, the

DVC woofer allows you to make up for speaker deficiencies with additional amplifier power.

SUBWOOFER ENCLOSURE TYPES

Sound is created by the movement of the woofer

cone back and forth. If a woofer cone moves

forward creating a positive pressure wave, this

same motion creates a negative pressure at the

back of the woofer. If these two waves combine

due to the lack of a wall separating the front of the

speaker sound from the back, the output from

the woofer is eﬀectively cancelled thus substan-

tially reducing the bass output of the speaker.

This wall is absolutely necessary and is referred

to as an acoustical „baﬄe“. It can be accom-

plished using a box of some kind or simply the

rear package shelf of an automobile to isolate

the front and back waves of the speaker.

THIELE-SMALL PARAMETERS

Every woofer has its own electromechanical characteristics which are called THIELE-SMALL

parameters. The three most important parameters include RESONANT FREQUENCY („fs“- the

frequency where the speaker moves with the least mechanical resistance), TOTAL Q („Qts“- the

„magniﬁcation“ of the cone movement at its resonant frequency), and VOLUMETRIC COMPLIANCE

(„Vas“- the equivalent volume of air that the woofer cone can displace for a given power input). Using

these parameters we can then calculate an optimum box volume for a particular woofer and reasonably

predict its frequency response.

COMMON ENCLOSURE TYPES

In the car audio world there are ﬁve types of subwoofer enclosures commonly used: INFINITE

BAFFLE, SEALED BOX (closed box), VENTED BOX (bass reﬂex), SINGLE-VENTED BANDPASS

(often incorrectly referred to as „5th“ order), DUAL-VENTED BANDPASS (often incorrectly referred

to as „7th“ order). No single design is superior because each has its own compromise in performance,

power handling and design complexity. The bandpass name implies a „built-in“ acoustical response

which has a natural highpass response (@ 30 Hz for example) but also a lowpass response

suppressing high frequencies (e.g., > 80 Hz).
