DESIGN

CONSIDERATIONS

Far

the

technically

minded.

The

harman/kardon

Sixty

and

Fitly

represent

harman/kardon's

most

ambitious

loudspeakers

to

date.

The

design

objectives

and

engineering

parameters

were

the

result

of

a

careful

consideration

of

the

technical

functions

a

loudspeaker

has

to

perform

in

a

listening

room,

as

well

as

the

impact

those

have

on

the

psycho

-acoustic

processes

that

interpret

those

functions.

The

design

objectives

for

the

Sixty

&

Fifty

included:

■

"Flat"

amplitude

response

across

the

audio

band,

both

on

and

off

axis

for

tonal

accuracy.

■

Maximally

wide

and

smooth

dispersion

with

a

minimum

of

dis-

continuity

for

accurate

imaging

and

a

wide

choice

of

listening

posi-

tions.

■

Undetectable

levels

of

coloration

for

fine

resolution

of

musical

detail.

■

High

sensitivity

and

power

handling

for

accurate

capture

of

musical

dynamics,

even

with

modest

power

amplifiers.

The

sound

radiated

directly

forward

from

the

loudspeaker

is

known

as

the

0°

or

"on

-axis"

response.

The

Sixty's

0°

axis

coincides

with

the

midrange

which

has

been

placed

at

ear

level

for

the

"average"

seated

listener,

the

Fifty's

with

the

tweeter.

The

0°

signal

reaches

the

listener

first,

and

with

more

intensity,

than

any

of

the

additional,

reflected

signals

so

it

is

critically

important

that

the

0°

response

be

"flat".

Sound

radiating

at

various

angles

from

the

loudspeaker

also

reaches

the

ear,

at

reduced

amplitude,

as

it

reflects

from

room

boundaries.

If

this,

"off-

axis"

sound

is

not

also

tonally

balanced,

the

speakers

will

prove

problematic

in

set

up

and

restrict

the

listen-

er's

seating

options.

"Coloration"

is

the

result

of

poorly

controlled

resonances

in

the

drivers,

in

the

cabinet

panels,

or

even

electrical

resonances

in

the

crossover.

By

carefully

designing

the

drivers,

a

maximally

wide

non

-resonant

range

has

been

achieved.

By

utilizing

steep,

4th

order

cut-off

slopes,

the

crossover

ensures

that

out

-of

-band

driver

reso-

nances

are

highly

attenuated.

The

latest

digital

data

acquisition

and

analysis

techniques

have

been

utilized

to

design

out

any

likely

elec-

trical

resonance

-problems.

The

reduction

of

cabinet

colorations

has

also

received

an

unusual

amount

of

attention.

The

best

materials

and

scientific

panel

studies

ensure

that

the

structure

is

extraordinarily

rigid

and

resonance

free.

The

fact

that

efficiency

and

power

handling

translates

to

wide

dynamic

range

in

speakers

has

not

been

overlooked.

You

will

notice

that

your

harman/kardons

capture

musical

dynamics

with

power

and

grace

absent

in

other

systems.
