ITEM 1. BUSINESS


Boston Acoustics, Inc. (the "Company") engineers, manufactures and markets
moderately-priced, high-quality audio systems for use in home audio and video
entertainment systems, in after-market automotive audio systems and in
multimedia computer environments. The Company believes that its products deliver
better sound quality than other comparably priced audio systems. Most of the
Company's products are assembled by the Company from purchased components,
although certain automotive speakers are manufactured by others according to
Company specifications. All of the Company's products and subassemblies,
including those supplied by outside sources, have been designed by the Company's
engineering department. Boston Acoustics' speakers are marketed nationwide
through selected audio and audio-video specialty dealers and through
distributors in many foreign countries. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations -- International
Operations" which is included in the Company's 1999 Annual Report which is filed
as Exhibit 13 hereto.

The Company was organized as a Massachusetts corporation in 1979 by Andrew G.
Kotsatos and former Chief Executive Officer, Francis L. Reed, who passed away in
November 1996. Its principal executive offices and manufacturing facilities are
located at 300 Jubilee Drive, Peabody, Massachusetts.

PRODUCTS

The Company has determined it has two reportable business industry segments:
Core and original equipment manufacturer (OEM) and Multimedia. Prior to fiscal
1998, the Company operated as a single segment. The Company's reportable
segments are strategic business units that sell the Company's products to
distinct distribution channels. Both segments derive their revenues from the
sale of audio systems. They are managed separately because each segment requires
distinct selling and marketing strategies, as the class of customers within each
segment is different. Each business segment has distinct product lines as
discussed below.

The Home Loudspeaker line consists of six bookshelf models currently ranging
in price from $100 to $420 per pair, four floor-standing systems currently
priced from $500 to $1600 per pair, two home theater subwoofer/satellite
systems currently priced at $700 and $1000 per system, and three powered
subwoofers priced at $400, $600 and $1200. Additional products for the home
theater market include five different center-channel speakers currently
ranging in price from $130 to $600 each and three diffuse-field surround
speakers ranging in price from $200 to $500 per pair. The Company also
produces magnetically shielded versions of most of its models and produces
three indoor/outdoor speaker systems (Voyager-Registered Trademark-,
Runabout-Registered Trademark- I, and Runabout II) currently priced from $200
to $400 per pair. The Company also produces a complete THX-Registered
Trademark- Home Theater speaker system priced at $3,600 and the
DigitalTheater-TM- 6000, a complete digital home theater sound system priced
at $599.95.

                                       1
<PAGE>


The Designer Series line is a collection of speaker systems engineered for
flush mounting in the walls or ceilings of homes, businesses and recreational
vehicles. There are eleven models in the Designer Series line with prices
currently ranging from $130 to $500 per pair.

The Automotive Series consists of 39 models of automotive speakers with
prices currently ranging from $60 to $700 per pair. The automotive line
includes high-quality full-range replacement speakers, sophisticated
component systems, and subwoofers. The component systems permit flexible
speaker placement and provide sound rivaling that of fine home speakers. The
automotive line includes the CX Series, the 700 Series of plate speakers, the
Boston Rally-TM- RC Series of component speakers, the Boston Rally RX Coaxial
Series, the Boston Rally RS Subwoofers and Band-Pass enclosure systems, the
Boston Rally RM Series, and the premium performance ProSeries Speaker Systems.

The Multimedia category of products sold through the Company's retailers and
via a direct Internet-based sales channel currently consists of three high
performance powered subwoofer/satellite speaker systems for computing
environments priced from $99.95 to $249.95 per system. The OEM sales of
Multimedia speaker systems sold to Gateway, Inc. ("Gateway"), a leading
global direct marketer of PC products, include the BA635 three-piece system,
the Digital MediaTheater-TM- three-piece system, and the DigitalTheater-TM-
6000, a complete Dolby-Registered Trademark- Digital 5.1 Channel Home Theater
System.

NEW PRODUCTS

In fiscal 1999, as in previous years, the Company introduced new systems for
all of our markets. These new products, described below, supplemented or
replaced certain products which in the Company's opinion had matured. The
Company believes that its new product offerings will increase penetration in
current markets, and help gain footholds in new markets.

A highlight of fiscal 1999 was the Company's introduction of the
DigitalTheater 6000. The DigitalTheater 6000 system is the first complete
home theater sound system with 5.1 channel Dolby-Registered Trademark-
Digital processing (the step beyond Dolby analog processing). It includes
five sonically matched satellite speakers and a powered subwoofer, driven by
a powerful six-channel amplifier. It is designed to utilize minimal space
while producing superior sound quality. It has a suggested retail price of
$599.95.

In fiscal 1999, the Company added an important new model to its
highly-regarded Lynnfield VR Series of floorstanding speakers. The new
Lynnfield VR940, priced at $500 per pair, utilizes an innovative new bass
driver designed and built by the Company that delivers exceptional
performance from a sleek enclosure. The VR940 received an "Innovations '99"
award for new product design and engineering excellence at the International
Consumer Electronics Show in Las Vegas.

The Company expanded its home theater speaker offerings with the introduction
of the System8000. This system is a complete six-speaker package with front
and rear satellites, a center channel speaker, and a 65-watt powered
subwoofer. It features the Company's MagnaGuard-Registered Trademark-
magnetic shielding and a DCD-TM- long excursion bass driver. The suggested
retail price is $700 per system.

The Company added two new models to its line of Compact Reference Series
bookshelf speakers. The CR4 and CR5 are both smaller than a typical hardcover
book, but offer smooth, wide-range sound. These new models are suited for use
in small, high-quality music systems, as extension speakers or as an upgrade
for speakers that are packaged with "shelf" audio systems. The CR4 and CR5
have suggested retail prices of $100 per pair and $150 per pair, respectively.

                                       2
<PAGE>


The Company's new Digital MediaTheater-TM- desktop home theater system also
debuted in fiscal 1999. Digital MediaTheater is a fully digital, self powered
sound system for the personal computing environment. It uses Dolby Digital
Decoding and Virtual Dolby to create a full 5.1 channel Dolby Digital sound
experience for games, movies, music and other PC multimedia audio sources.
The basic system includes two satellites and a hideaway subwoofer and has a
suggested retail price of $299.95. Optional surround sound speakers are
available for $50.00 a pair.

In addition, the Company introduced the BA635 three-piece multimedia sound
system. The system includes two diminutive desktop satellite speakers and a
miniature hideaway subwoofer. It has quickly become one of the Company's best
selling models. The suggested retail price is $99.95 per system.

Introduced in fiscal 1999, the Company's new Designer Series DX Pro in-wall
diffuse-field surround speaker is designed to be mounted flush with the wall
surface. The DX Pro is designed to duplicate the performance of surround
speakers in a movie theater, projecting sound along walls, ceilings, floors
and other surfaces to provide a realistic three-dimensional sound field while
remaining virtually invisible. DX Pro grilles and frames can be painted to
match their surroundings. The suggested retail price is $500 per pair.

In addition to the DX Pro, the Company added three additional new speakers to
our popular Designer Series in fiscal 1999. Two of the new speakers are
flush-mounted wall speakers--the Model 261, a 6 1/2-inch two way with a
suggested retail price of $250per pair, and the Model 251, a 5 1/4-inch two
way with a suggested retail price of $200 per pair. The third speaker, the
Model 315, is a ceiling mounted speaker priced at $150 per pair and can be
used to bring audio into hallways and small rooms, or to provide rear-channel
surround in home theater systems.

The Company also introduced in fiscal 1999, a completely new generation of
its flagship ProSeries products for car audio enthusiasts. The ProSeries
family is designed to handle high power without distortion and with accurate
frequency response to produce detailed, clean sound. ProSeries components
include woofers and distinctly small tweeters that can be mounted in a
variety of places. These components can be installed in most stock factory
locations without modifying car interiors, or in custom arrangements
virtually anywhere in the vehicle. They have suggested retail prices ranging
from $400 to $750 for the system.

In addition to the ProSeries .5 component speakers, the Company also
introduced completely redesigned 8-inch, 10-inch and 12-inch ProSeries .5
subwoofers for loud, undistorted bass sound in automotive environments and
are priced from $220 to $300 each.

In June 1996, the Company acquired the business of Snell-Registered
Trademark- Acoustics ("Snell"), a manufacturer of high-quality speaker
systems for traditional audio and home theater use. Snell specializes in
creating furniture-quality speakers for discriminating customers. Snell's
line of speakers includes products in four ranges - - compact speaker
systems, floorstanding systems, in-wall speaker systems and THX home theater
systems. Products range from $450 per pair for small bookshelf speakers, to
$45,000 per system for a complete 7-speaker THX theater system with
state-of-the-art digital room correction.

ENGINEERING AND DEVELOPMENT

The Company's engineering and development department is actively engaged in
the development of new products and manufacturing processes, the improvement
of existing products and the research of new materials for use in the
Company's products. The Company designs all of its products and
subassemblies, including those supplied by outside sources.

The Company's engineering and development staff includes 59 full-time
employees and three outside consultants. During fiscal years 1997, 1998 and
1999 the Company spent approximately, $3,187,000, $3,513,000 and $5,106,000,
respectively, for engineering and development.

MARKETING

The Company employs 29 salespersons and retains 13 manufacturer's
representatives who service the Company's dealer network. In addition, the
Company retains the services of two freelance public relations consultants
(one in the United States, one in Europe) to assist in the professional
promotion of the Company and its products. Boston Acoustics' home audio,
Designer Series (in wall/in ceiling models) and outdoor speaker products are
distributed in the United States and Canada through approximately 551
selected audio or audio specialist retailers, some of whom have multiple
outlets. The Company's car audio products are sold through approximately 332
similarly specialized retailers, some of whom also sell the Company's home
audio products. The Company's dealers usually stock and sell a broad range of
audio products including, in most cases, the Company's competitor's products.
The Company seeks dealers who emphasize quality products and who are
knowledgeable about the products they sell. The Company's Multimedia products
are sold through an OEM agreement with Gateway, through the Company's
retailers and via a direct Internet-based sales channel
(www.bostondirect.com). During the fiscal year ended March 27, 1999 one
customer accounted for 49% of net sales.

Boston Acoustics' products are also exported to dealers in Canada and sold
through exclusive distributors in over 50 foreign countries, primarily in
Europe, Asia/Pacific and South/Central America. Export sales accounted for
approximately 21% of net sales in fiscal 1997, 19% in fiscal 1998, and 14% in
fiscal 1999. See also Note 7 to Consolidated Financial Statements
incorporated herein by reference, pursuant to Part II, Item 8.

The Company emphasizes the high performance-to-price ratio of its products in
its advertising and promotion. Boston Acoustics believes that specialty
retailers can be effective in introducing retail customers to the high dollar
value of the Company's products. The Company directly supports its domestic
dealers and international distributors via a cooperative advertising program,
prepared advertisements, detailed product literature and point of purchase
materials. The Company also regularly advertises in national specialist
magazines including SOUND AND VISION, AUDIO, CAR AUDIO AND ELECTRONICS, CAR
STEREO REVIEW, VIDEO, HOME THEATER and AUDIO VIDEO INTERNATIONAL. During
fiscal 1999 the Company spent approximately $2,704,000 (2.3% of net sales)
for advertising.

COMPETITION

The Company competes primarily on the basis of product performance, price and
the strength of its dealer organization.

The market for branded loudspeaker systems is served by many manufacturers,
both foreign and domestic. Many products are available over a broad price
range, and the market is highly fragmented and competitive. The Company
distributes its products primarily through specialty retailers where it

                                       4
<PAGE>


competes directly for space with other branded speaker manufacturers. Audio
systems produced by many of the Company's competitors can be purchased by
consumers through mass merchandisers, department stores, mail-order
merchants, and catalogue showrooms. The Company believes it is more
advantageous to distribute through specialty retailers who provide sales
support and service to consumers.

Boston Acoustics competes with a substantial number of branded speaker
manufacturers, including Bose Corporation, Infinity and JBL (divisions of
Harman International Industries), Advent (division of Recoton Corp.), Polk
Audio, Inc., and Klipsch and Associates, Inc. Some of these competitors have
greater technical and financial resources than the Company and may have
broader brand recognition than Boston Acoustics.

In addition to competition from branded loudspeaker manufacturers, the
Company's products compete indirectly with single name "rack systems". Rack
systems contain all the various components needed to form an audio system,
and are sold by Sony, Pioneer, Technics, Yamaha and many others. Rack systems
are generally sold through mass merchandisers and department stores, although
many of the Company's dealers also sell rack systems.

MANUFACTURING AND SUPPLIERS

Most of the Company's products are assembled by the Company from components
specially fabricated for the Company, although certain automotive speakers
and multimedia audio systems are manufactured by others in certain foreign
countries according to Company specifications.

The Company purchases materials and component parts from approximately 274
suppliers located in the United States, Canada, Europe and the Far East.
Although Boston Acoustics relies on single suppliers for certain parts, the
Company could, if necessary, develop multiple sources of supply for these
parts. The Company does not have long-term or exclusive purchase commitments.
The Company does have a written agreement with one of its inventory
suppliers, which accounted for more than 10% of the Company's purchases
during fiscal year 1999. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations--International Operations"
which is included in the Company's 1999 Annual Report which is filed as
Exhibit 13 hereto.

SEASONALITY AND CONSUMER DISCRETION

The home and automotive audio markets are both somewhat seasonal, with a
majority of home speaker retail sales normally occurring in the period
October through March and a majority of automotive speaker retail sales
normally occurring in the period April through October.

The Company's sales and earnings can also be affected by changes in the
general economy since purchases of home entertainment and automotive audio
products, including loudspeakers, are discretionary for consumers.

PATENTS AND TRADEMARKS

Boston Acoustics holds seven United States patents and numerous international
patents, which relate to certain speaker technologies, assemblies and cabinet
design. The Company also currently has several registered trademarks
including Boston-Registered Trademark-, Boston Acoustics-Registered
Trademark-, PowerVent-Registered Trademark-, Tempo-Registered Trademark-,
Voyager-Registered Trademark-, and Runabout-Registered Trademark- .
Trademarks used by the Snell subsidiary include Snell Acoustics, Snell
Multimedia, Snell Music & Cinema and Room Ready-Registered Trademark-. The
Company believes that its growth, competitive position and success in the
marketplace are more dependent on its technical and marketing

                                       5

skills and expertise than upon the ownership of patent and trademark rights.
There can be no assurance that any patent or trademark would ultimately be
proven valid if challenged.

SIGNIFICANT CUSTOMERS

A significant portion of the Company's sales currently are to Gateway, Inc.
("Gateway") pursuant to a purchase agreement that extends through July 2,
1999. Since this purchase agreement with Gateway does not contain minimum or
scheduled purchase requirements, purchase orders by Gateway may fluctuate
significantly from quarter to quarter over the terms of the agreement.
Although the Company expects Gateway to continue as a significant customer,
the Company anticipates a decline in the quantity of products to be sold to
Gateway in fiscal 2000. The loss of Gateway as a customer or any significant
portion of orders from Gateway could have a material adverse affect on the
Company's business, results of operation and financial condition. In
addition, the Company also could be materially adversely affected by any
substantial work stoppage or interruption of production at Gateway or if
Gateway were to reduce or cease conducting operations.

BACKLOG

The Company currently has no significant backlog. The Company's policy is to
maintain sufficient inventories of finished goods to fill all orders within
two business days of receipt.

WARRANTIES

Boston Acoustics warrants its home speakers to be free from defects in
materials and workmanship for a period of five years, its Designer Series
speakers and its automotive speakers for one year and its multimedia audio
speaker systems for a period of three years. During the years ended March 27,
1999, March 28, 1998 and March 29, 1997, warranty costs recorded by the
Company were approximately $241,000, $193,000 and $232,000, respectively.

EMPLOYEES

As of June 24, 1999, the Company had 353 full-time employees who were engaged
as follows: 219 in production and materials management; 59 in engineering and
development; 49 in marketing and sales support; and 26 in administration.

None of the Company's employees are represented by a collective bargaining
agreement and the Company believes that its relations with its employees are
satisfactory.
