Please scroll down for more info.īassBox 6 Pro – A powerful speaker box design program with many professional features, including a design wizard and a huge driver database with the specs for thousands of drivers. Lastly, we offer two more tools: a collection of audio fonts and a utility to help preserve user changes to the driver database of our 'pro' software. It provides an affordable way to measure drivers-including woofers and many midrange drivers and tweeters. That's why we're pleased to list the Woofer Tester 2 by Smith & Larson Audio. Sadly, some companies fail to provide a full set of parameters and many allow considerable variation due to manufacturing tolerances. Most driver manufacturers provide them and the 'pro' versions of our software include a huge database with parameters for many thousands of drivers. Our speaker design programs require Thiele-Small parameters for each driver. It can import box designs from BassBox Pro and Lite and add to them the response of a midrange driver and tweeter to estimate the response of a full-range speaker. It models two-way and three-way speakers to help you design a passive crossover network for them. They do not model high-frequency or sealed-back drivers like tweeters. This is controlled primarily by the desired bass response and both programs focus on that aspect of design. They help the speaker designer determine a good box volume and, if vented, how it should be tuned. We offer two versions: BassBox Pro and BassBox Lite. This is the home of BassBox, our famous speaker enclosure design program. Welcome to the Harris Tech Audio website!
