  1. *and dont forget, you'll need false corners for those Khorns if there arent suitable ones in your space!
  2. Hey Doug. A couple of additional thoughts. Definitely raise up the tophats if you're going to be getting a dance party together (a riser equal to the height of the bass bin is a good rule of thumb). Doesnt have to be complicated, but make sure it's secure (ratchet straps securing through the top hat). Getting the mids and highs above the average human height means that nobody will block your high end by dancing in front of a speaker. For 100 people, a single horn loaded sub (which you can place the La Scala on top to also raise it up) will be a nice addition. Search "keystone sub" for a great design with plans that isn't too hard to fabricate. They're a great match. If you want to ensure that your tweeters and the guests ears stay intact, invest in an inexpensive DB meter, and before the event, take some measurements in the middle of the room. Set your max db by taking a reading and mark that place on your mixer or preamp. You can slowly climb to there as the night goes on and the room fills up, without any worry. Most importantly, your first responsibility as the host of an event is the safety of your guests, so make sure there are enough exits and have a plan in case of any common emergency that any volunteers also know. Boring stuff, but it will give you peace of mind, especially if your events grow. Best of luck!
  3. Hi all. Just received a pristine 4 way MCM setup through the forum and am planning on moving to active crossovers. Are there calculations floating around for time delays? Asking as the DSP unit I'm looking at (Minidsp 4x10HD) has a maximum setting of 9ms for time correction. Will this be enough for the big old folded bass bins? If someone has travelled down this path and can share, I'd much appreciate it!
  4. Here's the design for the false corners we've built for our corner horns, using someone's previous projection of the functional endpoint of the bass horn. We used 3/4" plywood and t-nuts and bolts to make it simple to disassemble and move: FalseCorner_Final.pdf
  5. Jazz, disco, funk and tasteful house, etc. Generally, music with positive energy and proven dance floor function!
  6. Great feedback everyone- apologies if the illustration is a bit deceptive- the grey boxes on the left and right sides represent columns that protrude from the walls. The speakers at the top are there for size reference. More detail on the setup- Currently have a passive distribution box that can attenuate speaker pairs. Amplification is provided by DSP-enabled power amps that have crossover, eq and delay capabilities. It's simple to run any of the channels as combined mono. Turntables are very well isolated, but the suggestion of an infrasonic filter is a good one. Again, all the Khorns are tucked in to false corners, with a riser under the tophat to bring treble above the crowd (see attached pic for the original David Mancuso solution using the PWK false corner design). The goal is not for loudness, but for a total surround effect. For reference, the original Loft NYC setup runs a L/C/R set of klipschorns at the back of the room and 2 more left and right pairs in the middle and front, attenuated to run at ~95-100db in the center of the dance floor when everything is working. An appropriate delay was applied to each pair, but in practise, not much of the L/C/R setup could be heard at the front of the room when full of people. Attaching an updated image of the last setup in the same room. The change this time is that i have 6 more klipschorns available. Was intrigued (albeit partly from an "has this ever been done before?!!" angle) if there would be any perceived benefit to more speakers, or if I might just be creating trouble. Thanks again for the warm welcome.
  7. Thanks for the reply! Trying to sort out when it's going to be diminishing returns to add more speakers. It's exciting to have them at my disposal, but I realize that MORE isn't always necessarily BETTER Sounds like you make some kids very happy in Detroit!
  8. Hi All! Looking for advice to build the best possible sound experience for an upcoming event I'm organizing. At my disposal are 6 pairs of Klipschorns, a pair of Industrial split LaScalas, and a pair of "Keystone" 18" folded-horn subwoofers that measure about the height and width of the bass bin of a Klipschorn, and stack nicely under the LSI's. I have false corners for the Khorns and risers for the top hats, to bring the high end above guests' heads. The event is a dance-focused evening inspired by the Mancuso Loft parties in NYC. All vinyl, songs played start to finish and a wide journey of genres. Room dimensions are 40 feet by 60 feet, with 12 foot ceilings, and a main dance floor area of 32' by 32'. The goal is an immersive-as-possible sound field surrounding the dance floor, while trying to avoid major combing issues or conflict between the horns. The attached file shows the scale of the room and the Khorn's and LSI's for reference. My knowledge of live speaker placement is low- would love some suggestions or best practises to make this an incredible experience for our guests.
