The judges will use the following criteria to determine the winners of the Speaker Design Competition:
The speakers under test are driven with a music signal fed from a CD player to an Emotiva Stealth DC-1 preamplifier, with no upstream signal processing, crossovers, or equalization. The Emotiva DC-1's internal DAC and digital-domain volume control are used. The Emotiva DC-1's balanced line outputs feed a stereo Emotiva amplifier to power the entries. Designs featuring additional channels of amplification, active crossovers, equalization, or other processing (including DSP) are restricted to our Open Unlimited category. For systems in the Open Unlimited category, the available outputs from the source are balanced (XLR)/unbalanced analog (RCA), and optical Toslink.
There will be 3 one-minute snippets of music listened to by the judges. These music selections are played per entry, each one minute in length, and these selections are the same for all speakers in a category, but different sets of tracks are selected for each category, with the selections for the categories having higher priced and more complex speakers being more challenging and possibly revealing of sonic flaws. Before each speaker plays, the level is set using pink noise, with SPL monitored via our calibrated Dayton Audio OmniMic V2 system, so that all speakers play at the same level.
Each speaker will be evaluated and rated by the judges, then tabulated and results entered into a spreadsheet. These results will be combined with the audience submission votes to declare winners in the aforementioned categories.
Judging sheets will be sent by mail to the designer's home address following the event. In the event of a tie within a class, the judges will select the ultimate winner.
Commercial entries or entities are prohibited: Individuals or entities that sell finished speakers (part time, full time, or any time) are excluded from registration. Should it be determined that you are in the commercial sales of finished speakers your entry will be removed. Please contact us should you require further explanation or clarification.
Contest committee members will have final say whether a project is excluded or not from competition.
Having roots in the DIY hobby himself, Jerry McNutt holds a BS in Electrical Engineering from Auburn University. As most young DIY'ers experience, studying took a backseat as he found himself more often in the garage building cabinets and systems rather than the Auburn Library. He built his first speaker project, a DIY Subwoofer, from an article in a magazine back in 1984 using a 12" McGee Radio driver that was manufactured by Eminence. He considers this time of speaker building as preparing him for a career in the audio industry. Professionally, he's been involved in creating OEM drivers for Ford, Honda, and Chrysler. For over eighteen years, Jerry has been working at world-renowned Eminence Speaker LLC located in scenic Eminence, Kentucky. Jerry began as a Design Engineer at Eminence Speaker and now is their Product Design Manager.
Tom Perazella is a retired Group Director of IT who began building audio kits at age 15. He has a Bachelor of Science Degree from UC Berkeley and is currently a member of the Audio Engineering Society, Boston Audio Society and DC Audio DIY Group. In addition to traditional audio electronics, Tom has built sophisticated AC power soft start units that handle large arrays of electronic equipment and provide protection against over and under voltages. His speaker protection designs integrate power over time with rates to cover different heating and cooling cycles and can detect frequencies out of the range of the drivers. Tom has designed speakers using planar magnetic and Heil Air Motion Transformer drivers for mid and high range units, and very high linear displacement sealed box subs. He has also extensively used DSP for crossover and equalization. Tom has written for Audio Amateur, Speaker Builder and AudioXpress magazines for over 20 years and currently resides in the Washington, DC metro area.
