GOLIATH DIFFUSERS - SPECIAL WALNUT

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. Every single diffuser well (block) is stained by hand with a BEAUTIFUL Special Walnut wood stain to create a stunning finish and a truly unique panel.

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.

Lightweight and True to Size — Best for Casual Use
Size: 9.5, Color: Navy, Size: 9.5, Color: Navy
It is nice to see the Amazon Essentials brand expand from household essentials to apparel and shoes. I ordered the Amazon Essentials Men's Lightweight Knit Running Sneakers. The product is made in Vietnam and comes in a shoe box, which is nice. I've noticed that quite often, inexpensive shoes are delivered just in a plastic bag. The sneakers are ready to use and have no odors from glue, organic solvents, etc., which is common nowadays. I wear a size 9W or 9.5. These sneakers are 9.5 and feel like a typical 9.5 size, without surprises. The product is advertised as lightweight, and it is true. Each shoe weighs below 0.6 lb (265 grams). Inside is soft memory foam; the shoes sit on the foot well, snug enough and comfortable, and are easy to put on and take off. They seem like a good fit for spring and summer as casual footwear or for light gym use. The sole is simple and not designed for performance or high-impact activities. Overall, a solid, reasonably priced, comfortable everyday option, though not intended for serious running or training.

Budget buy while being as comfy and stylish as an expensive brand!
Size: 9.5, Color: Navy, Size: 9.5, Color: Navy
My 14 year old had been running his own business since he was 12. He does lawn care and snow removal. His go to shoes when it's too hot for his work boots has always been off brand hey d*de style ones which are terrible for that kind of work as they just don't have the ankle support. He's also had some Orthopedic arch supports custom made for him through the DR in the last year that he needs to use in whatever shoes he's wearing at the time. So I've been on the search for a simple pair of slip on shoes that he could wear while working long hours around our community. He's sent me this picture tonight before heading out. He said "I didn't feel like putting my arch supports in and these are so comfy that I don't even notice I don't have them!" They are sharp looking shoes that really stand out as of they were A high end pair! It's great that they can be an every day style or could be more of a sport shoe as they have the support and padding for both options. In our case they likely be green with in a day or two and it'll be interesting to see how well they wipe off between his work days. I can update this review once he's worn them a bit more. For now they have been perfect for versatility, size was true to size (I did order 1/2 size up, but only did that because he's growing so fast!) and they are definitely a great fit to a budget!!!!
