JkSpinner Posted July 17 Author Share Posted July 17 I sent several photo’s and a plan off to GIK Acoustics, who provided a different POV. They suggested that instead of creating a first reflection point by installing a movable panel in the opening to the entrance, that I should perhaps consider placing a few absorbing panels in the hallway to tame or absorb the sound in the hallway, thereby reducing the sound that can be reflected back into the room. they then suggested that I look at some type of diffusion on the rear wall. i like this approach as it was minimal. GIK suggested that only if I wasn’t happy with this, should I look at next improvement, which would most likely be bass traps on the front wall, or some type of treatment on the front wall. They suggested measuring at this stage as I needed to be careful of over doing it and creating a dead room. They did not go into why, however I am guessing that as I have two large opening in my HT / 2 channel room, that a lot of the sound escapes, so I therefore do not require the 35 to 50% coverage, or maybe that my room is totally unsuitable, and there is not much I can do to fix it anyway. Who knows. i do like their minimal approach, and I still think there a a few things I can try and improve before I measure. 2 Link to comment Share on other sites More sharing options...

I can't see why you think solving your specific issues can be done without measuring your room? I would suggest having a professional take measurements and interpret those measurements and recommend appropriate treatment. Mike Link to comment Share on other sites More sharing options...

Mi Mike I do have a specific scenario, especially when you look at the overall shape and size of my room. That is why I broke it down into specific questions.

I think the answer is something like this, and I am not suggesting you are wrong. Sometimes only you know and understand your room and its characteristics. I am absolutely convinced that I need to make some changes, understand some things a little better, like the effect of windows and blinds, open first reflection points etc, try and create some symmetry, change the layout, speaker position, lounge position, before I go down the measurement path. No need to hire a professional, good chance I will only be in this house for another couple of years. This is something I should have done years ago.

I think many of your comments hit the nail on my head Some kind of symmetry. I looked at placing some nice shelving in front of the door window. As the left speaker is probably 18” further from the left wall then the right wall, this would give me more symmetry in two ways, geometric and Reflective surfaces, however the wife will not have a bar of it, I am considering either one or two moveable acoustic panels on either side, creating first and second reflection points, but also offering some type of symmetry, this would also prevent some of the sound heading out into the highly reflective entrance/hallway. I am considering the soundbox moveable panels https://www.soundseasy.com.au/collections/acoustic-panels/products/soundbox-aq150w-movable-acoustic-baffle or some office type acoustic divides (maybe ikea) with primacoustic 75mm pans attached 1 Link to comment Share on other sites More sharing options...

But measuring after each change would help you to determine if those changes made a difference quantitatively, plus you would have your own qualitative perspective.

When I first moved the stereo into my current listening room 15 years ago, knowing what I know now, I think it would have been money well spent having a professional measure the room and advise appropriate treatment. On 27/07/2024 at 8:37 AM, JkSpinner said: before I go down the measurement path. I get that measuring your room can be a deep rabbit hole, but at least it's quantitative. There's obviously a cost involved in acquiring your own measurement rig (Umike ~$250 + cable ~$50 + mic stand ~$100), plus a laptop you possibly already have after loading free REW software). I've had the same measurement rig for over a decade - it's a good investment if you're interested in quantitative measurements of your room, speakers, etc. cheers, Mike Link to comment Share on other sites More sharing options...
