On April 15th 2008, the Audio Society of Minnesota will host a members-only loudspeaker design challenge. Information about the challenge will be added here as it becomes available.
The design rules are simple:
1. The only drivers used in this challenge are the SB Acoustics SB025F9 1" tweeter and the Peerless 831990 5" woofer. Due to interest and the sellout of the original two drivers, the contest has been extended to the Peerless 830341 woofer (a 4 ohm variant of the original) and a nearly identical substitute SB Acoustics tweeter is available if you reference the original part number.
2. There are two categories of competition, Budget class and unlimited class. The budget class must use one each of the chosen drivers per speaker and a passive crossover. The unlimited class may use as many of the drivers as desired, and may use active or passive crossovers. Entrants using active crossovers must provide their own amplification.
3. The club system will be used in the judging, and to facilitate connection all speakers which will use the club amplifier must have available standard-spaced banana jack terminals.
The idea behind this contest is that everyone starts with the same drivers, and the difference between the finished speakers will be solely in the execution of the design of the cabinet and crossover.
Judging criteria are: Sound quality, Build quality and Technical measurements, as judged by non-participants. Results to be available soon!
