  1. Bass trap cover fabric question

    Home Audio Acoustics
    I have seen many posts on many forums suggesting acoustical friendly fabrics to cover traps and while I can understand this for general absorption of the higher frequencies, I cannot understand why it is often also recommended for bass traps. When trying to trap the lower frequencies, people...
  2. Front Wall Trap Design

    Home Theater Design and Construction
    Here is my front wall trap design. By damping any resonances or reflections involving the front wall, making them decay and die down quickly, bass snappiness is improved, and soundstage and imaging (SS&I) detail are improved. With the two layers of absorptive material and a gap between, max LF...

    REW Forum
    Hi all, REW has really shown I need as many bass traps in my room as possible..... the house is getting painted and I've been told I need to tidy up the traps I've already got in place before I build any more! Do you think using an open pattern decorative wall panel as the front of the trap...
  4. Membrane trap resonance

    Home Audio Acoustics
    Hi guys Thinking about building some membrane traps to supplement my rock-wool corner panels. I've been doing some reading on membrane traps and have an idea..... Why not tune the resonance of the membrane to the frequency we need to trap? It should be very easy build a trap with a membrane...
  5. Bass Trap Test... did this fail?

    Home Audio Acoustics
    I heard a while ago about buying insulation and leaving it in the bag to test in out. The cheapest, easy to find rigid fiberglass in my area is Roxul R6 ComfrotBoard IS. I got 5 boxes of the stuff and did some tests. Did this fail as a test or is this stuff too rigid. Boxes have 6 panel at...
  6. Bass trap material confusion

    Home Audio Acoustics
    I have read and searched all types of professional and DIY bass traps. I plan on making my own DIY bass traps approximately 2ft x 4ft using insulation and Burlap to cover the panel. But I also read that Microsuede can also be used. I thought the bass trap material required a breathable...

  9. DIY Bass trap this weekend project - Got a ?

    Home Audio Acoustics
    I'm going to break down and build two bass traps so I can test them out and see how they interact with my room. My plan right now is to build two corner traps 6 feet tall that will basically free stand and fit into the corner. I will build a frame like a windows box using 1x10 on all the sides...
  10. My crazy bass trap design, with waterfalls!

    Home Audio Acoustics
    Hi everyone, first real post. I used REW to measure my bass traps, and picked up a few good construction tips from this site, so I figured I should make at least one post about how they went. So it's a variation on a limp mass absorbers, or membrane absorbers, whatever. The real difference in...
  11. Gik QRD monster trap

    Home Audio Acoustics
    I have read that there was a product that was going to be a Gik monster trap with a QRD Diffusor placed in front of it that was going to be released in 2010 but I can't find it on the site for sale did this item not work out or was it replaced with something else? It sounded like it would be...
  12. Trap wall spacing.

    Home Audio Acoustics
    I thought I would ask this because I have not seen it covered before. At what point when moving a trap away from a wall does it not become more effective but lose some of it's effectiveness? Like if I took my monster traps and mounted them on a stand and moved them a foot off the wall vs say...

    I got a question for you guys. I'm being forced to get a single mattress for my music room so I can sleep in the room when my Wife is sleeping with the new baby (she does not want me to roll over on the baby) or vice versa. Are there any heavy foam single mattress beds that would also work and a...
  14. corner trap question.

    Home Audio Acoustics
    I was thinking about taking a 6" thick 2x4 foot panel and instead of two to straddle a corner using 4 of them and placing them so they go the long way across the corner to space them farther away from the wall adding to how much they can absorb. Would this help sense I only have 2 corners in...

  18. DIY Bass Trap Evolution in Layman's/Simple Terms

    Home Audio Acoustics
    This is Home Theater specific and is in very general terms regarding Bass Traps--not Acoustic Panels for reflection points or higher frequencies. I realize there are many highly sophisticated designs, resonators and frequency specific traps out there commercially; but, in all honesty, the...
