When we play a hi-fidelity recording in our listening room, the sound that we hear is the product of many things: the performers, the recording environment and the skill of the recording engineers, the quality of our playback electronics and loudspeakers, and the room/acoustic environment in which we are listening.
This article, the second in a series of tutorials on the miniDSP, demonstrates how to use the miniDSP as a crossover/eq for a 4-way loudspeaker. The speaker is an open-baffle loudspeaker, a configuration that has been gaining popularity in DIY circles in recent years.
This is the second in my series of articles on building full-range loudspeakers. I decided to build a pair of small Fostex-based speakers for my next project, and chose the Solo 103 speaker from Humble Homemade HiFi.
Kris Adams writes about the first in a series of single-driver loudspeakers that he is building as a learning exercise. This first pair is the Pensil-70 design for the mark Audio CHR-70 fullrange driver.
This article by Nyal Mellor introduces three fundamental acoustical issues that room correction cannot address. They can only be addressed through good design, appropriate use of acoustic treatment, and appropriate system setup techniques.
This is a tutorial on using the miniDSP 2×4 “DSP in a box” for equalizing a subwoofer and integrating it into a two-channel audio system.
Duke LeJeune of AudioKinesis explains the theory behind the controlled-pattern offset bipole loudspeaker, and demonstrates how this configuration can – if used correctly – lower room-related frequency response anomalies.
Jason Wong describes his journey into DIY with the dual build of the Simple SE amplifier from tubelabs.com, and used in his active speaker system.
One of the great joys of the hi-fi hobby comes from doing it yourself – especially when restoring vintage tube equipment. Bill Thomas walks us through the first stage of restoring a Dynaco Stereo 70.
Distributed Audio Using Apple’s AirTunes, or ‘How I Came to Love the Airport Express.’ Joe Quinn walks us through the process of setting up our wireless home audio network.
