I built myself three 4 ft x 6 ft gobos, each made from a framed piece of ¾ inch plywood, a layer of 1/8 inch high-mass vinyl, and three 2x4 batts of acoustical/fire rockwool. Each batt is wrapped first in light tracing paper to keep fibers in, then all the batts are wrapped in theatrical polyester muslin fabric, which is durable and fire-resistant, if not entirely acoustically transparent.

this calculator has a great rep around the www. I find it super useful, and love the way it graphically depicts the hot/cold spots in a given set of dimensions.

hey guys. Ran across this while I was surfing the web. John has a good set of papers, and great acoustic calculators on his site. I made sure to save them in my spreadsheet program. I haven't watched them all yet, but I'm watching a few right now.

Hi folks,

I'm building a drum room in my garden, and we are at the stage of deciding on the windows. We are faced with the choice for the outer window with either standard double glazing but with laminated glass panes, or triple glazing with unlaminated panes. The company have stated that the triple-glazed laminate panes would be too heavy and not practical.

Hi all,

This is my first post, happy to be here.

The measurements of my room are as follows:

4.30m (meters) depth
3.00m width
2.70m hight

Now in my left corner is a small recording room made of plasterboard which is 2 meters in width and about 1.30m in depth.

Any recommendations from the experts?
I posted before regarding some bookshelf speakers that just needed betrer positioning.

Newer setup I just finished...
Will be upgrading monitoring chain in the future(been saying it for years right).

I'm building a live room for my studio. The room is a former bedroom and the dimensions are not ideal. (8'2" H x 12'1" x 12'9 1/2", plus a small alcove that was a closet with bifold doors. Doors have been permanently removed.) I do have the ability to completely rip it apart and rebuild it, but due to budget constraints, that will have to wait. For now, I'm working with what it is.

Hello,

Has anyone checked out this video? I wonder if it's an actual breakthrough or just smart re branding of treatment... I suppose the end result is the most important thing.. If people think it sounds good.. it is.. but it seems like there's some fancy marketing mumbo jumbo going on..

I have my Emu 1820M optical output going into an Onkyo TX-SR500 reciever,
out to two Sony SS-B3000 3-Way bookshelf speakers.
