DIY 2007 will, as usual now, not be a competition. I prefer to keep the focus on listening to whatever anyone may wish to bring and allow for feedback if desired.
Who's Bringing What
I added this section because some folks tell me what they expect or have in mind to bring. There's no guarantee that these will be present, however. This isn't a complete list of the possiblities at this point. Some other systems being considered did not come in email, so I've gone back online to find the posts. If I've missed any or if anyone has more to add, please send me an email and I'll update the page. I've also left last names as initials or all intials. If you have no issue with full name, please email on that, too.

Anyone coming to the NE event who has any component which they would like to bring is certainly welcome and encouraged.
Measurement Systems There is usually little time to measure upstairs due to the auditioning and limited space. My basement is my work area, so most measurements will be taken there. LAUD v3.0 will be available for systems that can be moved there. This will leave the living room primarily for listening sessions, but if it's not prudent to haul a system downstairs, we may try to measure upstairs when things slow down.
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 This Year SoundEasy has a lot of functionality. I've been using its Digital Equalizer/Digital Filter (DE/DF) capabilities with each crossover. It's really convenient to audition a design without ever building a physical crossover. This isn't really new this year, but I'll be using it with some new crossovers. There are also quite a few new changes in SE from last year's version.
Soundeasy will also be available downstairs if a demonstration is desired and if time permits. John K has may also give a demo of his ABC Dipole as well.
