  • Official Grand Rapids Blind Listening Competition - May 19

    Ok, last thread on the topic. The Eclipse 5.25" woofer was chosen as the driver for this competition. You can get one by filling out the following Google form https://goo.gl/MTcdM9 which will register you for the event and you'll get a code sent to you to get the Eclipse woofer at the special discount pricing. Official rules below:


    Budget
    The budget for the event is $250 for the drivers and crossovers. The woofer will be counted at the special price ($39) for this event. A bill of materials should be submitted with your build which show retail (not sale) prices. With the exception of the woofer, no other special pricing is allowed to be used for the event. Shipping costs do not factor into the cost of the build. With the exception of waveguides, cabinets and damping material do not factor into the cost of the build. Waveguides, if purchased, must be added to the build cost at retail price.

    Drivers
    You must use the Eclipse 5.25" woofer in your build. You can use it in any alignment or configuration you want but there must be at least one per side used. All other drivers are up to the builder, but must be currently available with a reasonable certainty they will be available in the future (i.e. no closeout or buyout drivers).

    Cabinets
    Any cabinet configuration is permitted. Non-adjustable stands will be provided at the event for bookshelf speakers.

    Judging
    The judging will take place on May 19 at the Meniscus facility in Grand Rapids. Listening will be done blind. Anyone involved in the setup will not be allowed to vote. Scorecards will be handed out to all in attendance and summed by category at the end of the day. The speaker with the top score will be crowned the winner.

    Other
    At least one of your speakers must arrive at the Meniscus facility in Grand Rapids NLT May 12 for measurements. They can be shipped in at your cost or dropped off in person. Return shipping is your responsibility as well.


    That covers everything I can think of in the rules, but if you have questions, just let me know.

Got to hear some nice speakers and some good music and hang out with some nice folks. I missed a picture of an unfinished MTM entry which was lacking a crossover. I would have like to hear what a pair of ID's could do. Many thanks to Meniscus Audio for hosting.

    Hi Ron, Thanks for posting a few photos!

    Glad to hear that everyone had a good time, even if attendance was a bit lower than expected. I swear every time I see those ceramicos from JavadS and Jeff B. I get more excited about doing my own build with some of those drivers. Gonna need to hear more about this tweeter forwardness that folks are describing. Not sure if that's inherent to the design or simply the crossover choices employed. That white cone though....

    Those would be the upgraded units for the CSS Audio P215 kit.

    Those went with the Creative Sound Solutions monitors we got to hear. I believe they were a $300 upgrade from their stock crossover and the base was 3D printed.

    One of the speaker cables was hooked up out of phase from the other at the amp.

    Here are the two ID entries.* Mine are the pair in black gloss Formica.

    What happened to all the other entries?

    I had no dog in the fight but was delighted to listen.. Both designs were very different having shared the same driver .. Both did a few things well and both had some limitations.. Hearing a kit with the same driver gave some help to it all to.. Once phase issue was addressed they both* sounded good , each in their own way .. The other designs were personal builds that are always fun to listen to the* ideas and x over design.. The Usher Isobaric by Craig K had big bass and a wide stage.. The Coaxial Red and white had a detailed sound but never did get to be heard in phase.. The CSS were great at bass for a 5 inch.. The Ceramicos had a warm bass but having heard them now twice I feel the Ceramic tweeter to be a bit forward.. The best of show goes to Mark and Chad for their hospitality and the hard work* Kudos to Kerry for his nice demo work and diligent positioning of each design..* The beer was great at the local pup and as always .. Great people who really love the hobby !*
