Applications

In recent years, there has been a shift in market demand for commercial

sound systems to deliver higher fidelity sound. Retail, restaurant, and

hospitality owners and managers are finding that their customers are

expecting the quality of their shopping or dining experience to be enhanced

by music reproduced at nearly the same sound quality they expect in

their home theaters and car stereos. Business owners now realize that

the excitement caused by a quality audio system can turn into increased

customer satisfaction. The FAPSUB-1, when used in conjunction with

other Atlas Sound full-range speakers, provides great sounding background /

foreground music reproduction suitable to these applications.

General Description

The FAPSUB-1 consists of a highly efficient 8” subwoofer designed

for optimal performance in its included enclosure system. The woofer

features an extended, vented pole piece for higher excursion and better

heat dissipation and a Kapton® voice coil former for increased power

handling.

A highly efficient, 3-pole filtering network eliminates unwanted high

frequencies from the woofer, while the 937 in3, tuned and ported, deep

drawn steel enclosure provides frequency response down to 45Hz

(±10dB). A specially designed rippled speaker dust cap helps eliminate

nearly all frequency artifacts emanating from the center of the woofer

cone.

A special low saturation 70.7V / 100V transformer is included with

primary taps at 1.9, 3.8, 7.5, 15, 30, and 60 watts (@70.7V) to match

and balance the subwoofer with full range speakers without the need

for separate amplification. A convenient front mounted selector switch

allows tap selection without the need to remove the speaker from the

ceiling. This tap selector switch also includes a transformer bypass

setting for 8 direct coupled applications.Ω /

Mounting is simplified with Strategy Series® style "Dog Leg" tabs that

allow easy installation into drop tile or drywall ceilings with the provided

tile bridge assembly. The tile bridge consists of two “V” shaped formed

mounting rails and a C-Ring assembly. The C-Ring can be attached to

the rails with the screws provided to extend support to the T-Bar grid in

suspended ceiling applications. Multiple hole locations are provided to

allow the C-Ring to be positioned to the outer edge the tile if necessary.

For existing dry-wall applications, the tile bridge C-Ring and support rails

can be inserted into the hole cut for the FAPSUB-1. For easy positioning,

the “V” shaped support rails match the shape of the C-Ring tabs for easy

maneuvering and location when working "blindly" above the deck.

For new construction drywall ceiling applications, the optional FAP82-TR

trim ring is available. This unit provides a marked location for drywall

installers to cut around, essentially reserving the desired location in the

ceiling until final installation of FAPSUB-1. Mounting holes are provided to

accommodate 16" or 24" OC stud / joist mounting.

A support ring is also provided on the top of the FAPSUB-1 enclosure to

facilitate an auxiliary support cable.

NOTE: IT IS MANDATORY THAT THIS SECONDARY SUPPORT

BE UTILIZED IN DROP CEILINGS FOR SAFETY AND SEISMIC

CONSIDERATIONS.

System Design Considerations

How many subwoofers to use, where to place them, and at what

wattage to tap them will be different in almost every situation.

Variables include:

Size of the Room

Speaker Mounting (Ceiling) Height

Ambient Noise Level

Type of Music

Available Speaker Locations

Generally speaking, separate electronic crossovers and amplification

are not necessary for the FAPSUB-1. However, in certain high SPL

situations the increased efficiency gained by using an active crossover

and dedicated amplifier is beneficial. The Atlas ASP-MG24 or models

from the Blue Bridge product line have DSP based crossovers for such

applications.

For contemporary music reproduction, the minimum subwoofer level

should be set to match the volume of the full range speakers; however,

for some high energy music applications the maximum level could be as

much as 10dB louder than the full range speakers.

Like any speaker, use of the boundary effect will increase the output of

the FAPSUB-1. Placing the loudspeaker within 3' of a wall will increase

the output by 3dB. Placement within 3' of a corner will increase the level

another 3dB (6dB total).

Subwoofers and the Inverse Square Law

Even though frequencies below 200Hz are relatively omni-directional,

listeners can still "localize" the subwoofer from the volume produced. To

avoid "hot spots" it may be necessary to use two or more subwoofers

tapped at a lower setting spread throughout the room instead of a single

subwoofer tapped at maximum wattage.

Ratio of Subwoofers to Full Range Speakers

Due to the many potential variables, it is difficult to give accurate

suggestions on system design. It is important for the system designer to

look at the required SPL at ear level, ambient noise in the room, speaker

/ transformer efficiency, and transformer insertion loss to determine

the number of speakers and amplifier power required. In 70.7V / 100V

systems, care should be taken so the total speaker power taps do not

exceed the amplifier's 70.7V output capability.

The following “rule of thumb” information and examples are offered to

provide a starting point for system design.

For “good” low frequency augmentation in a full range system (all

full range speakers and FAPSUB-1s on the same amplifier), a single

FAPSUB-1 should be used for every four full range speakers.

For “excellent” low frequency augmentation in a full range system (all

full range speakers and FAPSUB-1s on the same amplifier), a single

FAPSUB-1 should be used for every two full range speakers.

Ampliﬁer Limitations

Even with the extreme efficiency of the FAPSUB-1 it will not overcome

the limitations of an underpowered system. Be sure to allow sufficient

headroom by using basic system design parameters in choosing an

amplifier.

Example Small Sports Bar

Square Feet 1,500

Ceiling Height 9'

Peak Ambient Noise Level 75 dB

Program Digital Music

Full Range Speakers

Eight Atlas Sound FAP42T speakers tapped at 4 watts each (32 watts

total) will provide 90dB on axis at 3.5' ear height (15dB above ambient).

13.5' spacing between speakers provides minimum overlap coverage at

4kHz.

Subwoofers

Two Atlas Sound FAPSUB-1 subwoofers tapped at 30 watts each (60

watts total) will fill out the low frequencies at 8dB above the level of the

full range speakers. If boundary loaded into one corner of the room the

level will be increased another 6dB (14dB above the full range speakers).

Total Wattage: 92 watts x 1.3 Multiplier (for headroom) = 119.6 watts

Amplifier Power Suggested: 120 Watts Atlas Sound AA120

Ampliﬁer Low Frequency Capability

Many 70.7V / 100V power amplifiers on the market today are from the

era when business music systems extending down to only 100Hz were

widely accepted. These less expensive amplifiers are not capable of

driving today's high fidelity systems that require sound below 100Hz.

When specifying the Atlas Sound FAPSUB-1, which operates well below

100Hz, it is VERY IMPORTANT to use a power amplifier capable of full

output down to and below the lowest frequency going INTO the amp,

which is often around 50Hz. An amplifier with low-frequency capability is

absolutely crucial whenever the system includes a subwoofer and is very

important for today's high fidelity business music systems.
