More Than You Probably Want to Know About Room 
Acous cs  

 

The

 

acous cal

 

characteris cs

 

of

 

your

 

listening

 

room

 

have

 

a

 

major

 

e

ect

 

on

 

sound

 

quality.

 

This

 

is

 

so

 

important,

 

it

 

bears

 

repea ng

 

(so

 

feel

 

free

 

to

 

re-read

 

the

 

fi

rst

 

sentence).

 

If

 

your

 

room

 

has

 

good

 

acous cal

 

quali es,

 

even

 

mediocre

 

speakers

 

can

 

sound

 

pre y

 

good.

 

In

 

turn,

 

if

 

your

 

room

 

has

 

poor

 

acous cs,

 

high-end

 

speakers

 

can

 

sound

 

lacking.

 

Acous cal

 

quali es

  

are

 

determined

 

by

 

the

 

dimensions

 

of

 

your

 

room

 

and

 

the

 

amount

 

of

 

sound-absorbing

 

materials

 

present.

 

 

Because

 

this

 

manual

 

covers

 

the

 

installa on

 

of

 

your

 

new

 

subwoofer,

 

we

 

will

 

concern

 

ourselves

 

with

 

how

 

your

 

room’s

 

acous cs

 

a

ect

 

bass.

  

Bass

 

distribu on

 

is

 

strictly

 

determined

 

by

 

a

 

room’s

 

dimensions.

 

A

 

room

 

with

 

evenly

 

distributed

 

bass

 

will

 

deliver

 

the

 

same

 

volume

 

of

 

bass

 

in

 

di

erent

 

sea ng

 

posi ons.

 

Obviously,

 

you

 

can’t

 

do

 

a

 

heck

 

of

 

a

 

lot

 

about

 

the

 

dimensions

 

of

 

your

 

room.

 

Don’t

 

worry;

 

few

 

rooms

 

are

 

close

 

to

 

perfect.

 

You

 

can

 

however

 

maximize

 

the

 

even-

ness

 

of

  

bass

 

distribu on

 

by

 

properly

 

posi oning

 

your

 

subwoofer

 

(if

 

you

 

have

 

that

 

fl

exibility)

 

and

 

in

 

more

 

extreme

 

cases

 

using

 

mul ple

 

subwoofers.

 

 

And

 

note

 

that

 

while

 

virtually

 

all

 

of

 

today’s

 

Audio/Video

 

receivers

 

and

 

processors

 

include

 

mi-

crophones

 

and

 

room

 

correc on

 

circuitry

 

that

 

can

 

help

 

to

 

smooth

 

bass

 

frequency

 

response,

 

they

 

will

 

not

 

correct

 

for

 

bass

 

distribu on

 

problems.

 

 

Posi oning Your Subwoofer 

 

The

 

goal

 

in

 

placing

 

your

 

subwoofer

 

is

 

to

 

get

 

even

 

bass

 

distribu on

 

in

 

various

 

listening

 

posi-

ons.

 

Pre y

 

much

 

anything

 

goes

 

as

 

far

 

as

 

where

 

to

 

place

 

it.

 

We’ve

 

included

 

a

 

few

 

drawings

 

to

 

indicate

 

rela ve

 

posi oning.

 

We

 

know

 

that,

 

because

 

these

 

drawings

 

have

 

such

 

fi

ne

 

detail,

  

you

 

may

 

think

  

we

 

hid

 

in

 

people’s

 

homes

 

to

their

 

rooms

 

when

 

they

 

weren’t

 

looking.
