Got some of the random, super cheap , industrial glazed tile laid down in the chamber today.
The sound changed, for the better, but not as much as I thought it would. The high gloss paint actually made more of a positive difference to the sound of the space. I guess it was more square footage, but the tile is... um.... tile, so I thought it would sound brighter and slappier right away. It DOES, however, even out the verb tail quite a bit. The overall RT-60 in there is probably about 1.25 useable because of the ambient noise floor of being in NYC at all. The overall RT-60 of the room is probably about 1.5 seconds, which is what I was going for in the first place. If I can, I am going to shoot for closer to 2 seconds, with 1.5 useable. I also put a giant piece of bank security glass that some one gave me to hopefully knock down a little flutter echo in the corner. You can see it leaning in the corner. It weighs a lot, as it is about 5 feet but 1 foot by 3/4" glass. crazy heavy. Anyway, that helped a little, but then the tile really got things to move right. The tile is going to stay as randomized as you see in the picture, but with more tile laid in on top of this layer. So we wind up with a shiny, diffuse, crazy bunch of variation in the floor. The super glazed subway tile will lay on top of this shiny, but textured tile. It should be really surreal in there soon. even more than now. The 15" Mackie speaker is up on its stand firing into one of the walls that is super shiny, and all wired up. Tomorrow morning we will get some sounds happening down there. All the wire is done on the chamber end, just have to crimp a bunch of DL pins onto the other end of the snake and get it on the patch bay... then I can REALLY start to hear what needs to be done in the way of tuning and further construction/painting/tile/stuff....
