2024 InDIYana Event Info

Where: 

Hampton Inn, DuPont Rd. Fort Wayne.

When:

Friday April 26th -

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 we 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 April  27th- 

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 theme tracks are played (roughly 3 minutes time), 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 -

"Inner Sanctum" the complementing secondary volume for a woofer alignment in a 2way or 3way consisting of 1.5ft^3 gross. Stand mounts preferred, but not required.

Passive xover implementations only, please, for this challenge, but entering the challenge is not required for attendance if more than observing.

Photos or drawings of internal construction must be provided for verification as visual inspection will not likely be possible. Simple large window braces or simple large holes do not conform to the dual chamber specifications. This should be specified as a vent, PR, driver, or air flow restriction between the 2 chambers in the most common definitions.

Basically, the woofer alignment must incorporate a dual chamber arrangement. This allows isobaric, 4th or 6th order bandpass, Augmented PR (noted in the LDC, and recently included in Hornresp), multichamber aperiodic(MAPD), dual (or more) chamber bass reflex or DCR+, HPAS, or any other dual-chambered or more arrangement. Feel free to do the same with the optional midrange if you wish, but it is not required, nor will it take the place of the required woofer envelopment.

Since multiple woofers can be used, 2 different alignments or one for each woofer can be applied. They do however have to be different alignments if both woofers do not share both chambers. However, using a pair of woofers in the same plane facing externally will require it be a 2.5way, no matter either TMM or MTM. Same plane dual woofer 3ways, or 3ways with dual woofers facing externally are not allowed. Dual external woofers are for 2 or 2.5ways alone.

Dual transmission lines are also allowed via a single driver like the Bose cannon, or dual driver while following the above rules.

Stubbed vented alignments, as in 4thtry's Plummer's Delights from the Nano challenge a few years ago are allowed, BUT the stub chamber and port diameter must not be of the same shape or cross-sectional area. This constitutes 2 chambers, and therefore is allowed.

• Open back tweeters are allowed, no open-back midranges.

- multiple drivers are allowed.

- no dollar limits, spend or not!

- no in-stock, buyout, or NLA driver limits. If you have it on the shelf, the above apply, and wish to use it- PLEASE DO! Use up the stuff you've had sitting.

- No cabinet over 40 lbs will be hefted for demo by the InDIYana planning crew. If you build heavy, you can set them up! =-) 

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 non-theme max, please. If Max of 40 is not reached, then more will be entertained.

***Challenge entries will play 3-4 minutes of challenge-music, and on to the next pair. This is to keep the entries playing consistent selections. You are (normally) 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/award if you win the challenge. Nothing more, nothing less. This is just for fun!

Sponsors will soon be lining up. See Sponsor page for more information.

PS- Adult beverages:

PLEASE TAKE NOTE:

THERE ARE TO BE NO, AS IN ZERO, ADULT BEVERAGES CONSUMED WITHIN THE MEETING PLACE/CONFERENCE ROOM. THE HOTEL'S 'MEETING PLACE POLICY' DOES NOT PERMIT THEM IN ANY SHAPE OR FORM. IF WE WANT TO KEEP HAVING THIS EVENT AT THE HAMPTON DUPONT, OR EVEN AT ALL, I HIGHLY SUGGEST WE ABIDE BY THIS SET OF GUIDELINES.

PPS- 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 are typically not done by me. 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.

If you are not on the attendee list and would wish to attend, or would like to confirm your presence please send me an email. If you have questions you can ask via email to InDIYanaOrganizer@gmail.com

We would like to give a gigantic THANK YOU to our sponsors!

(Please see list linked above)

Thanks for your time, and interest, and I hope to see or meet you /here/there!
