COMPETITION CRITERIA

The judges will use the following criteria to determine the winners of the Speaker Competition contest:

  1. Craftsmanship (visual)
  2. Originality / Design (visual)
  3. Tonal Balance (audio)
  4. Clarity (audio)
  5. Imaging (audio)

The speakers under test are driven with music signal fed from a professional-grade Red Book CD player (TASCAM CD-01U Pro) through a 2-channel amplifier (QSC Audio GX3), with no upstream signal processing, crossovers, or equalization. The CD player’s internal DAC and digital-domain volume control are used. Designs featuring additional channels of amplification, active crossovers, equalization, or other processing (including DSP) are restricted to our Unlimited Category. For systems in the Unlimited category, the available outputs from the source are balanced/unbalanced analog, optical Toslink, and AES/EBU digital outputs.

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 OmniMic 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 votes will be added with the project submitter votes to achieve winners in the categories listed above. From this sheet, total point winners will be selected in the categories listed above.

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, judging will move to a head to head format with the ultimate winner selected by a show of hands.

Please Note:

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.



COMPETITION JUDGES

JERRY MCNUTT

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

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.

MATT PHILLIPS

Matt Phillips has been a tinkerer since he can remember. As a young kid, he loved taking things apart to see how they worked even if he couldn’t put them back together again. When he was about 13, he decided to tear into one of his father’s old Fisher speakers (without consent). For reasons he doesn't remember, this lead to his passion and hobby of speaker building.
Matt found out about Parts Express in an unusual way - he stumbled across a catalog during marching band practice. He has no idea whose it was or where it came from but he must have read through that thing a hundred times. He was an immediate customer! He continued to build and experiment through high school until he found a job as a technician at Parts Express when he was 19.
Matt's knowledge and experience has grown substantially in the last 12 years and has allowed him to become one of the most experienced techs at Parts Express. He has designed and built countless crossovers and enclosures. He has learned many tricks of the trade and continues to build and learn as much as he can to help not only himself, but help others learn this great hobby.
