DIY 2019 New England

Canton, Massachusetts

November 2, 2019

Updated October 23

I've been hosting this event for most of the years that it has been held. I'm pleased to be hosting it again. The crowd has dimished in recent years, but we always have some good systems to audition and there's always a lot of discussion.

Who's Bringing What

At this time I don't have a list of who/what. I'll update this page as I get feedback. Send me an email for additions/corrections.

My primary system will be my dipoles (woofer and mid) with monopole tweeter with the Ultimate Equalizer handling crossover duties.

Years my primary system was a 3-way closed-box design. I'm putting that one back together to compare to my dipole and to have it as a secondary system. I hope to audition them both.


As before, let me say...BRING YOUR CDs!!! The crowd determines what is played and when, but please bring any CDs that you like. There's no guarantee of getting a lot of time on anything, but everyone is encouraged to request their preference during the day. At times the same passages are played for sake of comparison, but I'd like to have more variety of music to keep things from getting stale.

Auditioning Equipment

My equipment will be as noted below.

Anyone coming to the NE event who has any component which they would like to bring is certainly welcome and encouraged.

My Dipole System

SoundEasy has a lot of functionality. I've previously been using its Digital Equalizer/Digital Filter (DE/DF) capabilities with each crossover and am now using the v17 introduction of the Ultimate Equalizer. It's really convenient to audition a design without ever building a physical crossover. It's even easier to "design" a crossover by making SPL measurements (impedance not needed), selecting the Fc and slope for each section, then runing it. As simple as that. There are other considerations, of course, but those are the basics. I still like to offset drivers to prevent the need for excessive time delays that impact the off-axis. Diffraction control also helps in the same way that it does for passive crossovers, but it's once drivers are mounted on baffles, the process is quick. So many combinations can be tested so quickly.

Snacks and Lunch

I provide some finger food and snacks to carry us through to lunch, but if you have an idea of something better than chips, bagels and veggies with dip, feel free to add to it. Maybe you want something sugar-free or low sodium, etc. There's always quite a bit left over in any case, so don't go overboard. Don't feel like you have to bring something either, in the end there's usually more than we can eat.

We typically order out for lunch, most often for delivery pizzas, and everyone chips in. This usually works for everyone, but there are options if anyone wishes to make the trip to the end of my street to one of several restaurants. There's Japanese, Thai, Vietnamese and a couple of others. They are all less than a mile away.
