The purposes of the study are as follows: 1. To delineate the functions of the different component parts of a loudspeaker so as to show its working relationship with the enclosure or baffle 2. To analyze the basic types of speaker enclosure designs and to define their application for use in woodworking shop projects. 3. To explore the skills and knowledge needed to build correctly a highly functional speaker system cabinet. 4. To present these construction techniques in such a way as they might be helpful to the prospective builder of a speaker system enclosure. 5. To provide a helpful guide for the design and construction of hi-fidelity cabinetry and to help the builder avoid needless and costly mistakes of acoustic and aesthetic design.

A combination of fax and mail questionnaires were used to estimate consumption of wood based products by the U.S. cabinet industry and evaluate current management issues affecting the cabinet industry. Group 1 companies (>$20 million in sales) were contacted and sent a fax questionnaire. A random sample of 1034 Group 2 companies (<$20 million in sales and >10 employees) were sent a mail questionnaire. A total of 19 usable questionnaires were received from Group 1 companies and 217 usable questionnaires were received from Group 2 companies. Group 1 respondents averaged 1,108 employees and $125.81 million in sales. Group 2 respondents averaged 27 employees and $2.31 million in sales. A shortened questionnaire (questionnaire 2, one page) was sent to half of the Group 2 sample frame resulting in twice the response rate as that of the long questionnaire (questionnaire 1, three pages). Results indicated that the cabinet industry used an estimated 484 million board feet of hardwood lumber. Nearly 95% of the hardwood lumber purchases were grade 1 common or better. The most common used species were red oak (44%) and hard maple (24%). An estimated 58 million board feet of components and 68,344 doors were also purchased by cabinet manufacturers in 1999. Softwood lumber use was estimated at 25 million board feet, consisting primarily of white (49%) and southern yellow (36%) pine. The most commonly used panel products were particleboard and hardwood plywood, at an estimated 1,044 million square feet (1/2 inch basis) and 279 (3/8 inch basis) million square feet respectively. Other panel products used by the industry were medium density fiberboard, hardboard, and softwood plywood. Approximately 156 (any thickness) million square feet of veneer was used. Lumber purchases were primarily direct from sawmills (66%) for Group 1 companies and from wholesalers/distributors (53%) for Group 2 companies. Panel product purchases followed the same trend with Group 1 companies buying primarily direct from manufacturers (44%) and the majority of Group 2 purchases coming from wholesalers/distributors (84%). Group 1 companies sold their products through factory sales people (54%) and to home improvement/building supply centers (37%). Group 2 companies sold their products through factory sales people (77%) and to builders and remodelers (62%). The largest proportion of cabinet types sold by both Groups 1 and 2 were face frame kitchen cabinets (74% and 38% respectively). Companies from both groups reported producing certified (green) products. The majority of companies indicated they purchased some parts from outside sources. Companies from both groups reported considering alternative materials to substitute for wood. Products that were mentioned include strawboard, urban waste MDF, and plastic mouldings. Concerns rated highest by cabinet companies were finding qualified employees, increasing raw material prices, keeping qualified employees, and wood quality. / Master of Science

The idea of curiosity has evolved over time and is a major building-block in the foundation and expansion of museums and their precursors, cabinets of curiosity. These proto-museums began in Italy and spread throughout Europe in the sixteenth and seventeenth centuries. Cabinets of curiosity and museums transformed as visitors traveled to burgeoning collections across the Continent and England. Individuals visited curiosities for a variety of reasons. Some treated outings to collections as social events in which they could see others in their social circles and perhaps rise in social status if seen by the correct people. Others were merely curious and hoped to see rare, astonishing, monstrous, and beautiful objects. Scholars of the era often desired to discover new items and ideas, and discuss scientific and philosophical matters. The British Isles are removed from the main body of Europe, but still play a major role in the history of collecting. A number of private collectors and the eventual foundation of the British Museum contributed seminally to the ever-increasing realm of curiosities and historic, cultural, and scientific artifacts. The collectors and collections of Oxford and London and its surrounding areas, drew a diverse population of visitors to their doors. Individuals, both foreign and local, female and male, visitors and collectors in Early Modern England chose to actively participate in the formation of a collecting culture by gathering, visiting, discussing, writing about, and publishing on collections.
