GOLIATH DIFFUSERS - NATURAL WOOD

Frequency Coefficient Range: 600Hz - 4000Hz  
Weight: 50lbs
Dimensions: 2ft x 2ft x 8in
(Actual - 24.5in x 24.5in x 8in)

QUALITY FABRICATION:

Each diffuser is hand built by our team in North Carolina. We build every diffuser with care, love and attention to every last detail.

Each well (block) is sized & placed methodically, based off of a  primitive root equation for acoustic diffusion - to optimize effectiveness of the panel.  

These colossal skyline diffusion panels are fabricated using Western Red Cedar - Commonly used for acoustic instrument & guitar making. This results in a uniquely beautiful panel with appreciable visual characteristics and distinguished sonic attributes. 

Next Generation's exclusive Goliath Diffusers are designed to be visually beautiful, structurally durable and have the unique objective of scattering (diffusing) low & mid range frequency sounds equally in all directions. 

These diffusers are mathematically designed to diffuse and scatter mid-range / treble frequencies equally in all directions. The acoustic diffusion wells are calculated using a primitive root equation for diffusion. 

APPLICATIONS:

Goliath Diffusers will make a significant improvement acoustically & visually to studio rooms, live music rooms, theater spaces, mastering rooms, restaurants, venue stages, etc.

Goliath diffusers will help in taming muddy mid-range and low end frequencies within your room. They will allow sound to move freely - but will break up & evenly disperse sound reflections throughout the room. This can significantly improve acoustical properties in your space. This is due to the occurrence of direct reflections (sound bouncing back in forth from a wall to the opposite wall over and over again) being what causes decreased sonic intelligibility when it comes to reverberating frequencies inside of a room. 

Goliath Diffusers also help with correcting phase issues caused by the shape of your room and how audio is responding within it. Direct reflections caused by square/rectangular shaped rooms can create "peaks and nulls" in distinctive frequencies at various locations within a room.

These nulls develop when the amplitude of different frequencies significantly decrease in specific areas within the room. This occurs when the phasing of a reverberating audio wave meets an opposing wave formation at the same frequency causing phase cancelation. This means that the audio in your room is not being accurately represented and will have different perceived levels at different locations in the room. Our Goliath diffusers will aid in fixing this issue - especially in mid-range & treble frequencies. 

Peaks and Nulls cause audio within a room to not be accurately and evenly represented everywhere throughout the room. Having different levels of perceived frequencies at certain locations is extremely problematic in any critical listening, recording or mixing environment. Diffusers will aid in reducing/correcting peaks and nulls within your room. Especially when placed or installed at critical reflection points within the room.

 

Installation: 

These panels are heavier than standard acoustic panels and require adequate mounting hardware. Therefore each Sonic Diffuser panel comes with FREE custom mounting cleats. 

A "panel cleat" will be pre mounted onto the back of each panel. A corresponding "wall cleat" will also be included inside of the box with your order. Simply hang the provided "wall cleat" wherever you desire the panel to be placed on the wall.

Secure the wall cleat to a stud when/where possible. Wall anchors will substitute where necessary. Our custom panel cleats are made by hand in our shop & are cut to the exact specs of your Sonic Diffuser panel's framing. Our custom made Panel Cleating is the best method to utilize when hanging heavy acoustic / diffusion panels. Utilizing this method will save you A LOT time when installing your Sonic Diffuser and will insure they're mounted properly & secure.

Soft, Cooling Pillowcase That Smooths Out Chunky Filling
Color: White, Size: King, Color: White, Size: King
I accidentally ordered the king size instead of queen, but it still fits my shredded latex foam pillow fairly well and feels comfortable. The pillow has small but chunky latex shreds, and the added foam layer in this pillowcase not only smooths out those chunks but also adds a bit of extra thick comfort, making the pillow feel more uniform. ​ It seems to help with temperature regulation—if anything, it’s subtly cooler or at least not any warmer than my previous pillowcase. I’ve washed it twice so far, and it shows no wear and seems well built, so it should hold up over time and seems totally washable. Overall, it’s a very functional item, and compared with similar products, the value seems reasonable; I’m happy with the purchase and just wish I had ordered the right size. ​

Good quality cover
Color: White, Size: Queen, Color: White, Size: Queen
First, this pillow cover arrived in a plastic bag (see 4th photo), not a box as the photos online show. Although that does not matter to me, it may matter to other people such as those who intend to give this as a gift. One of the photos I included shows the fabric makeup which is mostly polyester and memory foam with the outer cover having “40% Bamboo Rayon.” It seems like an overstatement to me to market this product as a “quilted bamboo pillow cover” where there’s very little, if any, actual bamboo in it. If you have read up on what “bamboo rayon” actually is, you’ll understand. The material make up aside, the cover is soft and puffier than a cotton pillowcase. Bamboo rayon does have qualities that allow airflow for a cooling type of effect. It washes very nicely. As for the size of the pillar cover, I have tried several pillows inside this case, and the case is at least 2 inches longer than every standard pillow I own (See second photo). Pillowcases with a zipper generally are more fitted in every dimension. This pillow cover fits in all dimensions, except for it is longer than necessary. Not a horrible thing, but worth mentioning. The sewing of this product is good. It has a standard plastic zipper. There’s piping around the entire seam area for touch of class. The gray piping on mine matches the quilting. This is not quilting of the standard sense where threads go through to the other side. It is more of a faux quilting, which you can that on the inside in the photo with the tag. Overall, it seems to be a good product especially for people who sweat when they sleep.

Very easy and convenient
Color: White, Size: Queen
Absolutely in love with this pillow case. I have a tendency to let the kids on the bed with snacks and it’s helpful to just be able to take the case off and put it in the washer when it’s dirty

Nicest Bed Pillow Protectors I have found!
Size: Body
I have ordered these pillow protector cases multiple times for pillows that are extra thick or lofted as these seem to be very comfortable, durable, and really protect the pillow itself! They wash up well if there is any sort of stain. Nice bed pillows can be a real investment…it’s both easier to wash these protectors with my bed linens and more sanitary overall. Thin pillow protectors either wrinkle or fail to actually protect the pillow itself from whatever…dust mites, head lice, sweat, make up, skin care, spit up….be sure to follow the instructions for laundering and drying them and they will last a long time! My experience is these protectors keep my pillows from getting lumpy or bunching up, so promote a better night’s sleep!

This is definitely not your average pillow protector!
You have to see and feel this pillow protector to understand just how good it is (photos and videos just don't do it justice). It looks and feels like some sort of fancy premium luxury pillow case, but it's a zippered pillow protector! I always thought pillow protectors were just a simple white cotton zippered pillow case in order to add another layer in addition to the pillow case, but this pillow protector from COOP Home Goods completely blows me away. I just kept going, "Omg, are you kidding me? This is just a pillow protector?! Wow!" The only negative is, the zippered opening is too small. When I tried to put my brand new COOP pillow into it (I have the pillow that has approximately 15,000 reviews), it was very difficult. This was before I removed any of the filling for customization though, which I still needed to do. I finally got around to doing that and I probably removed about 1/3rd of the filling because I'm mostly a stomach sleeper, so I'm sure the pillow protector will be much easier to put on the next time I remove it, but I'm not going to remove it until I have to wash it because I don't want to be stuck trying to put it back on again! That's how annoying it was to put on. I'm keeping it though because I'm hoping it will mean I'll never have to wash the pillowcase or especially the pillow! That'd be awesome. I recently upgraded from a MyPillow Premium and I hated washing it (it was always a mini project, so I am hoping to be completely done with that). I contacted COOP about the small opening and they said, "We do have plans to change the zipper placement on our pillow protectors, however, production has not started and we do not have a firm date to provide you with at this time." They also reminded me that the pillow can be "bent and manipulated" (their words) into the pillow protector. See next paragraph though to understand why I didn't want to handle the pillow too much, otherwise I would've just done that instinctively. There is one more negative aspect that's worth mentioning, but it's due to a personal issue (there's nothing COOP can do about it). I have rough dry skin on my hands, and the material (40% Bamboo-derived Viscose Rayon, 60% Polyester) is rather 'catchy' on my hands. If you have rough dry skin and if you've ever tried to handle something made out of silk, you know what I'm talking about; you can't enjoy the silky smooth texture. This isn't anywhere near as bad as silk, but it's just bad enough that it's worth mentioning. I think it's due to the Bamboo-derived Viscose Rayon. The pillows are the same way for me due to the pillow case. That's probably what made the pillow case so difficult to put on because I was trying to be very careful not to get my skin flakes all over everything from just "manhandling" it, which is what I should've done and then just vacuumed it clean. heh I won't use lotion though because I don't like the idea of getting lotion on everything I touch every day, and it makes my hands sweat much easier - especially in the summer. So, I prefer to just deal with clean but rough dry hands. I guess another negative thing could be that it's not possible to just buy 1 pillow protector. These are 2-packs. I only needed 1 pillow protector and I only wanted 1. I would've gladly paid $15 for just 1. So anyway, beyond that, these pillow protectors truly have that "wow!" factor. They're exactly as advertised and more (because some things are only possible to know about by experiencing them for yourself).
