Here's a book on building your own speakers that's packed with great new ideas. Building a pair of underfloor 15-inch subwoofers for your home, integrating quality ported enclosures into your walls or ceiling - even developing your own spherical-shaped hi-fi speakers.There's also coverage of software to design speaker enclosures, to determine the specs of second-hand or unknown drivers, and to measure the performance of your new speakers. Here are ideas that you can take and apply for yourself, without needing to buy expensive brand-name drivers or have high-level woodworking skills. Practical and down to earth, the 68 large-format pages are packed with content - nearly 150 full colour photos showing step-by-step construction, and the projects start from just a few dollars. This second edition adds extended coverage on testing speakers, how to obtain quality loudspeaker drivers at low cost, how to cheaply adjust tweeter levels, and building a subwoofer from pre-built enclosures.
