“Pi-Phi” by Ben “Wolf” Shaffer; Completed 9/14/06

Design Goals:

I wanted to try and see how well a speaker can be implemented using textbook formulae, and a ready-made Dayton crossover. I also wanted a simplistic approach to get the most out of a 2-way speaker barring any frequency response abnormalities, or prior measurement.

Driver Selection:

I chose a set of drivers found at a surplus electronics shop. The tweeters are a vintage pair ...

“Compellurgy 8” Subwoofer

-Design goals-

I received a door prize at a Parts Express sponsored event known as “Dayton DIY” in 2005. The driver was not as yet released to the public, and was the first finished production unit of this model. I had no specifications or parameters to utilize in the modeling and creation of this project. I had no idea of what this driver was capable, and decided I needed to create a project worthy of its menacing looking attitude. I went ...

“Bitty-Boom V2 pair” by Ben “Wolf” Shaffer 5/27/07

I built these about 2 yrs ago.

Design Goals:

I saw a post by “Nate-Diggidy” on the tech-talk forum, about trying a Dayton classic 8 ohm unshielded 6.5” in an 8” diameter tube, with an 8” SDVC PR on the opposing end. This project was to further its performance characteristics, and Nate is okay with the fact that I did this. I have his permission. The project is for a decent set of stereo subwoofers that ...

The Sir Audinums/Duke Audinum by Ben “Wolf” Shaffer, 1-23-07

-Design Goals-

This project is an offshoot of my Audinum design, using the same drivers in an MTM driver arrangement. The purpose is to have timbre matched Left-Center-Right speakers to complement the previous project placed in the Surround location. This will enable the same sounding setup to be used for all but the subwoofer in a 5.1 home theater arrangement. The purposes for the new MTM layout are: a wide ...
