First Look

2016 Midwest Audiofest

Speaker Design Competition


Under $200 winner "DCT-1 by AcoustaKip," by Shawn Kipka

What do 45 home-built speaker entries and more than 80 enthusiastic DIYers equate to? A fantastic two days at the Midwest Audiofest Speaker Design Competition. Sponsored by Parts Express and held in Springboro, OH, at a venue around the corner from its offices, this year's competition spanned two days, starting the evening of July 8 and continuing into July 9. This will be only a taste of that event with an in-depth report to come at a later date.

The Midwest Audiofest Speaker Design Competition has been held for 12 years. To sum up the 2016 event, when I first saw the entries I was completely blown away with the range of sizes, design philosophies, and finishes. To make things interesting there were four categories in the competition, total cost of drivers for a pair under $200, total cost of drivers for a pair over $200, all drivers sourced from Dayton Audio (the house brand of Parts Express), and unlimited.


	Open Unlimited winner "Stink Eyes," by Nick Santorineos

Entries were judged on performance in five categories; craftsmanship, originality/design, tonal balance, clarity, and imaging. Rankings ran from 1 to 10, with 10 being the highest. Each of the judges submitted 1-minute music segments that they thought would be good for testing. Those were reviewed and four sets of three segments were selected to match the expected capabilities of each category. All speakers in each category were auditioned using the three selected segments for that category in the same order. Before each entry was auditioned, a pink noise track was used to set the same output level, offsetting any sensitivity differences assuring an even playing field.

The evening of July 8 was reserved for a Meet and Greet where the contestants mingled and swapped stories and got to know the judges. There were three judges-Jerry Mcnutt from Eminence Speaker, Tom Danley from Danley Sound Labs, and myself, Tom Perazella from audioXpress. All three of us have extensive experience in speaker design and testing. Following that, competition began with the unlimited group.


Dipole speaker with push-pull dipole bass

As soon as the first entry began playing, it was very clear that we had something special here. Additional entries generally confirmed those first impressions. After attending many shows and hearing some commercial speakers that promised much but sometimes did not deliver, it was very refreshing to hear so many of these speakers perform so well. I just kept saying to myself this is phenomenal.

The next day the anticipation was high to see if the level of quality carried over to the other groups. I won't keep you waiting, it did. Although in some cases, performance was limited, especially in the under $200 category which is understandable, I was impressed at the level of performance in each category. Especially considering the Draconian restrictions that can occur when dealing with a less than $200 total driver price limit for a pair of speakers. It was hard to believe how high the performance was in that category.

In summary, DIY is alive and well! All of the contestants can hold their heads high and revel in the knowledge that they really get it when it comes to building great speakers.

Congratulations to all of the Midwest Audiofest Winners!

Show Report

The Exciting Sounds of Audio Expo North America (AXPONA) 2016

By Oliver A. Masciarotte

In this show report for audioXpress, Oliver Masciarotte highlights some of new and notable products, from headphones and DACs to amplifiers and (some) speakers that caught his attention. "A placid six-hour drive brought my trusty hybrid and its passengers from the Twin Cities to the suburbs of Chicago for another spring exploration of the new and novel in high-end consumer audio. Held April 15-17, AXPONA 2016 was hopping, with attendance up 16% this year. The count settled at 5,934 attendees through the doors to see 400 exhibitors in Rosemont's Westin O'Hare."

Acoustic Simulation of Audio Devices with Actran Software

By Diego Copiello
(Technical Marketing Manager, Free Field Technologies)

Loudspeaker design is not a trivial exercise, and as a result, high-performance acoustic simulation software is essential to get accurate predictions that help an engineer develop superior products. Demand for simulations at early design stages are increasing because cost and timing constraints make it impossible to prototype and test every design idea and much can be learned from simulation results, which cannot be obtained in the test chamber. Acoustic simulation software enables audio system manufacturers and integrators to determine the acoustic performance easily, accurately, and early by providing detailed information about what to expect before hardware is built, and more importantly, why because simulation illuminates the physics involved in each design. Second, a simulation enables designers to rapidly evaluate several different configurations at initial stages of product development and enables the assessment of complete system performance to ensure superior audio quality. Actran, MSC Software Company's acoustic simulation solution is based on Finite Element Analysis (FEA) technology. It provides predictive simulation capabilities to assess the vibro-acoustic performance of audio devices, which include speakers and microphones.
