NBP Acoustics Panels - Individual Sales - $30 per panel

Here is the individual sale.

This is a continuation of the thread found here: http://forum.polkaudio.com/discussion/175209/acoustic-panels#latest

Price per panel does not include shipping, but these are light so it shouldn't be too bad. Payment via paypal gift.

If interested, please post up how many you would like. I currently have 109 in stock but haven't figured out how many I'll be keeping for myself. I know I've got about 4-5 locals jumping in on this and they get priority for obvious reasons.

    Haven't absolutely any Idea how acoustic panels could help or even if they are needed and if so how many behind the A9s and would red match with black and gold what you say Derek?

    There are many things you have to consider with panels and room acoustic treatments. The simplest is first reflection points both along the sides and ceiling (not counting floor).

    Then it's not just first reflection points but you have to calculate the secondary and tertiary reflection points that typically cause lower frequency reflections that require a different panel variant than the typically higher frequency first reflection points.

    Then you have to calculate your sbir frequency nodes. Add bass traps there.

    Then you have to calculate standing waves and then compensate for them.

    Plus much more.

    The simplest is to figure out your first reflection points.

    Those panels skip has for sale have minimal bass absorption given the size. What you'll reduce is slap echo and anything above 250hz. Too much of that and the system sounds unbalanced without proper lower frequency control.

    In a regular room if you target the first reflections correctly, you're probably looking at 2 48" panels up front, 2 on each side, 2 in the ceiling, and 2 in the rear (though it depends on seating position, too close to the rear wall and you're better with absorption, too far and you're probably better with diffusion).

    So if the panels skip are selling are 24"x48", then you're looking at approx 10.

    Joey sounds confusing to me I guess there is more to it than slapping up a few and calling it a day, thanks for the explanation.

    Took us a while to figure it out, as good as I am with math, my buddy is somehow better. We read through lots of material and experimented and ran scenarios and sweeps, we developed algorithms that we could calculate 1st 2nd and 3rd reflections points and their corresponding frequencies, then we were able to calculate standing waves and sbir frequencies and then we were able to derive constructive and destructive frequency plots based on speaker location and seat position.

    You would be served well to start by handling first reflection points. You'd be amazed how much better defined your system becomes. But it's nowhere near enough.

    First reflection points are the most critical. If you don't treat those you will never get a quality soundstage with accurate imaging. There are so many ways to treat a room and each one has its own target frequency. Like Joey said, these are not designed for bass absorption.

    Any system can benefit from even basic treatments.
  • adb3daadb3da Posts: 478
    Depending on shipping costs, I would be interested in 4 panels.

    I'm looking into options now and will probably defer to another Polkie for assistance in shipping these.

    I remember years ago there was a very good thread on here on figuring out the first reflection point.....but Im too lazy to look it up. What Im generally trying to recall is if the first point was on the side walls or back wall.....anyone, anyone? I have room on my side walls and front walls for these....the back walls are already spoke for with art work....

    First reflections are where the speaker will reflect first and have a direct line to your ears. This includes all 4 walls and floor and ceiling. The floor usually has carpet or a rug and the ceiling is usually left off as a single first reflection point. All four walls should be treated though.

    If you are keeping count, each speaker has a first reflection on each wall, so just treating the walls can leave a total of 8 treated areas.

    I urge anyone thats looking to snag some its awesome and better than any 4 figure cable upgrade. I took all my panels down from the back theater to move things and my wife came in and said ' you can really hear your voice echo in hear now'

    Normally its on the side wall.

    The easiest way to find reflection points is to sit in your main listening position and have someone else move a mirror a mirror along the side walls of your room. Whenever you can look into the mirror and see the speakers, thats a reflection point.

    To elaborate on this... JimAckley was at my place one night and we were talking in the room. At one point, he just stops talking, looks at me, and starts laughing. I ask him about it and he tells me "I've never been in a room where my voice didn't echo. It's weird not hearing myself talk."

    For those who haven't met Jim, he has a voice as deep as lightman's with more volume.


    I miss that room.

    Bump. Still waiting for addresses from several guys. Expect shipping to be around $25 for a set of 4.
  • DSkipDSkip Posts: 15,894
    Where'd everyone go? Had about a dozen inquiries and one follow through. I'm not upset but I was really hoping this would get some guys into quality panels for less than wholesale cost.
  • adb3daadb3da Posts: 478
    For anyone on the fence, I must give Skip a shout here. These panels are very well made and mine arrived in one day. I have not had a chance to hang them yet but wanted to post some positive feedback.
