October 15th, 2005
As last year, DIY 2005 will not be a competition. There have been discussions about having another competition, but I would prefer to keep the focus on listening to whatever anyone may wish to bring and allow for feedback if desired. I don't think that my listening environment allows for ease of evaluating a large number of designs, anyway.
Auditioning Equipment This year will be a bit different. In addition to my usual hardware (and any that others bring), plans are (currently tentative) to have some equipment from a manufacturer on hand for demonstration. When I get confirmation, I'll update this page.
My equipment will be:
Anyone coming to the NE event who has any component which they would like to bring is certainly welcome and encouraged.
Measurement Systems There will be at least two and maybe three different measurement systems available. I will have sSoundEasy v11.0 and LAUD v3.0. SoundEasy will be running under Win2K with the M-Audio Delta 410 sound card. I'm planning to have LAUD in the living room for making measurements of systems auditioned. The other system withLAUD will be downstairs and available for measurements there as well.
My basement is my work area, so most measurements will be taken there. This will leave the living room primarily for listening sessions.
I have a small number of baffle inserts for my large (now 2m x 2m) baffle for testing raw drivers. If I happen to have the size needed, raw drivers may be measured if anyone requests it.
What's New SoundEasy has a lot of functionality. I've been learning it for a while in preparation for using its Digital Equalizer/Digital Filter (DE/DF) capabilies with a 3-way system. I had just gotten the DF working when my PC was dumped due to power droop (old receivers can do that when powered on). This damaged my sound card (!), but a new (used) one is on the way.
My plans are to have the DF working and if time permits between now and the 15th, have one or more versions of minimum-phase crossovers and transient-perfect ones. This system may remain in the basement, but if I have enough success I may move it upstairs for better auditioning.
Another benefit is that the capability of SoundEasy can be demonstrated. I suspect that John K will be able to show many of its functions that I have not yet had time to learn.
