April 26, 2019 – April 27, 2019 all-day
Hampton Inn Fort Wayne
5702 Challenger Pkwy
The 13th annual InDIYana speaker-DIY event!
Hampton Inn, Dupont Rd; Ft Wayne, IN
Friday 26th, April –
8am(open) Music 9am to 10 pm (nothing loud after 9pm, per hotel’s request. Background music only.)
We usually go out for dinner about 6-7pm, and then return and chat. Friday’s schedule tends to be informal. However, with typically over 20 designs usually lined up for demonstration, expect something interesting going on all day long! Normally most start arriving after noon, but I will be there all day for whomever shows up. The first 3 hours can be interesting with only a few people present, so come at 9:00 am if you can swing it, or 8am to help set up!
Saturday 27th, April –
8am(open) Music 9am to 6 pm (we have the room until 10pm)
There will be a couple breaks, plus lunch break in the day. Electronic gear will be provided (amps, sources, cables). Please make sure your project can use banana jacks, or bring adapters so you can use the bananas in the speaker leads that will be present. Bring stands if you wish, but a pair of 22″ stands will be present if you should need them. (If your bookshelf speakers have spikes underneath, please bring a pad to set them on.)
Presenter will have 5 minutes of their own music on an audio CD, to be played following the house tracks. If you do not bring music, you only get 5 minutes play time per project. There will not be 10 minutes on the event disc, only 5 minutes. For the theme, only the house tracks are played, but we can revisit them later for more if time allows. Please withhold synopsis until after the contest is over. Contest portion is normally started about 11am on Saturday, with the goal to be done by lunch.
Project theme or challenge details –
Bare Minimum: First off, let me say I am not trying to have entries sound terrible or worse than average, but I am allowing the monkey to throw a wrench into the game with this certainly being a possibility- however this shakes out. Taking a side-step from last year’s approach resembling that of some commercial products, and using a bit of ingenuity from the former Black-Box contest, I came up with a set of ideas I like to call “The Acceptable Flaw” approach. As chosen in a poll by your fellow builders, Bare Minimum was the selection most favored.
Driver modifications are allowed, but if made, approximate cost of mod should be added. Cost of resin if you print your waveguide, for example. Please keep cabinet volume under 1.25ft^3. Stand-mount preferred, but not required. No single driver should cost over $125, and utilize a 2-way strategy. Overly minimalist xover is the MO here. For example; cap on tweeter only. 5 crossover parts or fewer per cab. $300/pair including xover parts and cost of driver mods if done. Decent drivers = fewer parts? We’ll see….
“C-Note” PE kit drivers are not allowed in this challenge. 38mm dome tweeter or smaller if using a dome, and must be labeled as a tweeter by the manufacturer. No wide-band/full-range drivers this time around for tweeter use. Multiple woofers/midbasses are allowed as long as the price restriction is met. Design should stand alone and play as full-range audibly as expected. No subwoofer can be added.
Q: Is an adjustable rotary L-Pad Attenuator one part or two? A: Splitting hairs, but I think it depends on how you use it;
Like a rheostat (single resistor) = 1.
Like an L-pad (2 resistors) = 2.
No active xovers or line-level xovers in this passive xover contest.
Gross volume inside the 6 walls(?) Of the cabinet. Bracing will come out of volume requirement if using max volume. I have no problem with thicker walls, et al, but the outer shell should be the max dims.
Ports should all be internal this time around, as there is no outer max dimensional criteria like in the nanotech theme. These are expected to be a basic cabinet with all contained inside.
One theme entry per person, please. Also to keep chances for everyone to demo over the 2 day event, please bring no more than 2 pair; one theme and one not max, please.
***Challenge entries will play 3-5 minutes of challenge-music, and on to the next pair. This is to keep the entries playing consistent selections. You are welcome to play music of your own on your challenge entry at a time outside of the challenge. This is to keep the extent of time usage in the contest to a minimum.
Good luck to those who enter the challenge! You can bring whatever speaker project you want, but challenge entries must meet the above criteria.
Gloating rights will be the reward if you win the challenge. Nothing more, nothing less. This is just for fun!
Sponsors will soon be lining up.
PS- no buyout drivers allowed, unless a regular price can be located, and that price is to be used to total costs.
PPS- Design must be repeatable, so drivers must be available for purchase. Waveguides and PRs are included in the driver cost calculation. Drivers that go on clearance or become NLA after your purchase has been made and no longer are available elsewhere will be allowed. Since the event themes are being announced about 10 months in advance, this is bound to happen occasionally. The basis will be left on the honor system. NLA drivers that have a twin ‘newer rebadged model’ can be used at the new model’s retail cost.
PPPS- Adult beverages:
OK, BIG CHANGE FROM LAST YEAR!!! PLEASE TAKE NOTE.
THERE ARE TO BE NO, AS IN ZERO, ADULT BEVERAGES CONSUMED WITHIN THE MEETING PLACE/CONFERENCE ROOM THIS YEAR. THE HOTEL’S ‘MEETING PLACE POLICY’ HAS CHANGED, AND THEY ARE NO LONGER ALLOWED. IF WE WANT TO KEEP HAVING THIS EVENT AT THE HAMPTON DUPONT, OR EVEN AT ALL, I HIGHLY SUGGEST WE ABIDE BY THIS NEW SET OF GUIDELINES.
PPPPS- All tracks selected for the house tracks are done by a select few, myself included, and are not revealed until the day of and at the event. Theme tracks typically are not compiled or known by anyone except the person picking them, which is typically done by Shawn Adams, this event’s 2007 founder. If and when everything goes right, there should be CD copies of the house tracks available in limited quantities for those that might like one. MAC has in the past graciously hosted the tracks on their event-archiving website.
