I agree 100% sound absorption panels and room treatments are a hell of a lot cheaper than all of the equipment people put into their rooms with the room being the most important. I'm glad you finally got past your skepticism like I did a few years ago. I think the combination of proper room treatment and Ignite Audio products is a match made in heaven. Couldn't be happier. Ignite-burn! Lol😂😂😂 |

My family room is WAF friendly  Just remember... a good sounding room doesn't mean slamming absorption everywhere... Good rule of thumb is treat only 50% of the wall and of that 50% use 35% diffusion and 15% absorption. I haven't "finished" my panels yet but plan on it this year.  |

Do you hbe any engineering inot those diffusers? Where did you het the math? Id rather make them if they’re not a Huuuggggeeee project. Thanks so much novis |

I cranked those panels out in a few hours. Yes it's designed. Scatter 646hz.. diffuse 1300hz HF cuttoff is 4500. Not a large range but I sit close to them so I cannot go to a lower frequency without getting comb filtering...
uses standard furring strips too... uber cheap to make. I think it's about $15 per 4' in length. The 8' ones at the ceiling/wall only cost about 28 bucks a piece.

They are an inverse design to my needs. I wouldn’t feel right throwing the plans around when not everyone needs this range they could need other range.

I've read that using 2 subs helps to reduce the need for some acoustical panels

I'm completing construction on my year long media room project. I have three metal doors; one midway along the right hand wall, and a double metal door in the back left corner. Someone suggested I use carpet tiles on the doors to help cut down on reflection. I have no problem doing this and think it would probably look good, but I'm also considering acoustic foam or some other options. I do want this to look attractive when complete. Any thoughts on this?

I can't imagine suggesting complete coverage except in a very unusual case. The usual mantra is "do no harm" and "use as little as needed to do the job". That's often a few panels at first reflection points, and some bass traps for particularly nasty rooms (like mine).
Commercial acoustic panels come in a lot of colors and styles (look at places like Kinetics Noise Control in addition to the usual audiophile sites like GiK and RealTraps). You can find places that will print images on acoustic fabric that you can then attach to standard Corning OC-703 or whatever. Or add drapes and place panels behind the drapes. Corner bass traps may work if there is nothing else in the corner.
Diffusers generally cost more but are effective above the bass region, do not deaden the sound as much, and may have higher WAF since they are more art-like (IMO).

I got a heavy, all-wool, hand-knitted Persian rug (brand-new) at a yard sale for $20. I plan to hang it behind my listening couch, about a foot from the wall behind it. Between the rug & the wall, I'll place a diffuser. Best I can devise with the space available...

IME: It's absorption properties are poor relative to other treatments (such as the ubiquitous Corning OC-703) and the foam tends to fade, dry out, and fall apart as it ages.

We're in a new house with a totally enclosed approximately 11x17 room, 9 foot ceilings, thick carpet on the floor. We don't intend to go crazy with room treatment, but absolutely need some stuff. I've temporarily had to do electronic means to tame the room gain (actually quite frightening bass shaking the house!) and put some "interesting" wall treatment, unattached, stacked up, to gauge where I might want to put real treatment. Here's a pic:
So there's some moving boxes and/or Emo shipping boxes to act as sound traps, a slight nod towards design of anechoic chambers - I did say slight, yes? I had more, some on the left cabinet, and some stacked on the sides. I found the ones on the sides took too much away from the "liveliness", so it appears I should concentrate on back and back corners (bass traps for those I believe). It's also possible that "liveliness" is really still excess reverb, we'll see. Even this "minimal" set-up helps considerably in taming treble harshness.
Obviously this is not your typical WAF acceptable design, but we're not complaining for now, but it's still a mess back there ;-) I'm thinking I will still have some minimal simple design sound absorption on the side walls, but I will have to go step by step. My big wonder is how can I test out the "real" sound traps on the walls without actually nailing them up. If I stacked them on closed boxes might that be reasonably safe? I'm not looking for a scientifically intense measurement situation, more seat of the pants ;-)

Just so you know..... Using empty cardboard boxes as "architectural placeholders" is just fine... But an open empty box is not at all like a bass trap... In fact, it's more like an organ pipe,or a resonating chamber, and will tend to both ring and vibrate... Those boxes will definitely color the sound in new, and interesting, but unpredictable, ways. We're in a new house with a totally enclosed approximately 11x17 room, 9 foot ceilings, thick carpet on the floor. We don't intend to go crazy with room treatment, but absolutely need some stuff.

You can't be serious about that stuff behind your couch....can you? 🤦♂️ |

You can't be serious about that stuff behind your couch....can you? 🤦♂️ Just to be clear... the empty room otherwise was an echo chamber and I needed something quick and immediate to tame that. The empty boxes did that - quick and immediate. Of course it's not the ultimate solution ;-) We haven't even unpacked movie discs yet. I've done a small amount of looking on the web for attractive and effective echo/bass trapping but it is/was much lower priority than getting the rest of the house in shape. Etc. I just thought this might be "amusing" to y'all, and quite frankly it IS effective to a large degree - just butt ugly, that's all ;-) |
