In the pipeline this year...
- Each of the the projects will be revisited, adding details of what worked and what didn't
- An Infinite Baffle sub has been built. With a displacement of over 20 litres, this is giving some serious enjoyment
- A new section will describe the use of the Room EQ Wizard software and a BFD to tackle in-room response
- The free software will continue evolving, although most people seem happy with it already
- The Port flaring experiments now look at how much the inside flare can be reduced before it becomes noisy
- The WinISD section will be expanded with more tutorials and help on entering parameters
- As always, there will be plenty of links to sites more knowledgeable than this one
