The Tempest
By Scott C. Blaier 31 Mar 1996
Introduction
The impetus behind this project was my sister's fiancé's need for a high output, low distortion, loudspeaker with excellent low bass extension. The caveat was to achieve these goals on a budget under $ 500.00 per pair. It is always a challenge to design a good loudspeaker, regardless of price. But it is even more difficult when cost is an issue. Throughout the design, I tried to maximize sonic performance for every dollar spent, and searched for the highest performance to price ratio components on the market today Fig. 1.
