Product Description

Nankarrow QuadraFuse™ QD1 is a two-dimensional diffusion panel that is best applied to walls or ceilings, providing multi-reflection on both vertical and horizontal planes in sound critical spaces. It performs on mid and high frequencies, brightening and clarifying sound.

Don’t risk missing results by simply putting random blocks in a series that are not calculated, as that will not give even acoustic diffusion. Make the room sound bigger with TRUE diffusion of high frequencies with our precision-cut, 23-root, two-dimensional Quadratic Diffusor.

So, let us explain Acoustic Diffusion.

What is diffusion?

While absorption is vital for any room an area that can’t be ignored is diffusion. Diffusion is the even spreading of sound waves from a direct source. So, if you have a small space diffusion can give the idea of a room being larger than it actually is by providing increased natural ambience.  By having no absorption or diffusion installed in a space speech intelligibility is reduced and sound quality is degraded and while absorbent materials will help a great deal in solving that dedicated well designed diffusion such as our Nankarrow QuadraFuse™ acoustic diffusor will be much more effective.

Nankarrow QuadraFuse™ Acoustics diffuser panels gives your recording studio or listening environment a sense of spaciousness in your music by addressing the above issues without deadening the room too much. Sound diffusers scatter sound across two planes: horizontal (left & right) and vertical (up & down), which is called acoustic diffusion. This two-dimensional scattering broadens the soundscape and makes a room sound larger.

Nankarrow QuadraFuse™  diffusers you can be sure that your speakers or monitors don’t have a bommy sound , with an ill-defined mid-range, an aggressive high end and an uneven bass response  where some notes boom out and others seem almost to vanish.

Nankarrow QuadraFuse™ can be used in control rooms, broadcast studios, live rooms, home theatres – anywhere a range of instruments and voices are recorded or heard, rehearsal rooms and other performance spaces.

Nankarrow QuadraFuse™  is made from from high quality Taiga Spruce Wood  form Russian Snow Forest. It’s instantly alluring design results from unique research based on the acoustic properties of the wood. Nankarrow QuadraFuse™  to act as a diffuser, letting you tame reflections without rendering your room dead.

The panel’s elegant design enhances the visual appearance of any room.  Thanks to its unique look and versatility, the Nankarrow QuadraFuse™ is one of our best sellers.

Nankarrow QuadraFuse™ is made from high quality Taiga Spruce Wood from the snow forests of Russia, the QuadraFuse™ is notable not only for its effective performance in solving problems like lack of speech intelligibility or music definition, but also for its premium design, gives interior decorators exciting new possibility for creative acoustic design that fits perfectly in any kind of room.

  1. Excellent!

    Sanath Joshi

    Excellent! I ordered 3 of these diffusers to cure troublesome ‘hot’ reflections on a side wall. The installation of these Nankarrow diffusers has not only fixed the acoustic problem, it has added a welcome sense of timing and space. Affordable, beautifully made and very easy to install. Highly recommended!

    Pranay Jhaveri

    I received the Diffuser in approximately 15 days in perfect condition, as soon as it was installed I could notice the difference of sound in my listening room. Reasonably priced and worth being purchased.

  4. Great Product very effective

    Rajesh Shetty

    Like all Nankarrow products,this item is well made, looks attractive and is reasonably priced.
    I bought several of these diffusers to maintain a good balance of diffusion, as suggested by auralexchange team to compliment the Nankarrow absorbers I also purchased. Collectively, they make a huge improvement to the acoustics in my studio.
    As an added bonus I can hold my car keys in one of the cubby holes..very handy!

Our head-office is in Mumbai; however, we don’t have a showroom or physical stores. We're an online company - we distribute our products online all over India via a distributed warehousing system - we have warehouses in 8 locations. Since our products are technical and used for solving specific acoustic problems, they do not attract walk-in customers. If you want to buy our products, just place your order online or reach out to us via the contact forms.
We do not offer Cash on Delivery. Our products are extremely large and bulky - you can fit a human being into most of our boxes. As a result, one of the highest costs in running this company is the money paid to courier companies like Fedex, XPressBees, etc, which runs into crores of rupees annually. If we allowed COD and the buyer changes their mind and refuses to pay during delivery, we incur double shipping costs (a) for sending the product to the buyer + (b) for shipping the product back to our warehouses. In some cases, this may be more than the value of the product itself. For this reason, we find it impossible to offer Cash on Delivery.
We follow maximum transparency in showing you actual delivery dates at a product level. The exact delivery dates are visible on each product page, cart page, checkout page, as well as your order confirmation emails. Once your order is shipped, regular shipping updates are provided via SMS.
We supply products only. We're an ecommerce company and our focus is on importing, distributing, manufacturing, and supplying a wide range of technical isolation & acoustic products across India. For installation you can engage local contractors / carpenters. Please contact us if you need specific information on installing any product in our catalog.
We accept returns upto 30 days from the date of receipt of product. If you need to return a product, just contact your sales representative and we will arrange a reverse pickup via Fedex. Your refund will be processed within 3 days after we get it back. We charge a 15% fee for restocking the product so this is subtracted from your refund. This is waived off if you have not removed a product from it's original packing and are returning it unused.
Your order could be in several spots... our warehouse, our custom-shop manufacturing units, anticipating dispatch, with the courier on its way, or conveyed. The principal thing to check is have you had your dispatch email? If yes, at that point it's en route. You can track your order by clicking your tracking link from that email. In the event that you haven't got your dispatch email within a week of placing your order, please do contact us.
ONLINE PAYMENTS: Pay us via Netbanking, credit cards, debit cards, wallets, or UPI via our online payment gateway. Over 95% of our customers use this option as it is fast and secure.

    Being a playback singer and wanting to record good vocals and do Voice Overs in a home set up has always been my dream. Decent acoustic treatment is a must. And Aural Exchange have some amazing products in their range. My interaction with Ashutosh started on the phone in Aug 2020 and finally ended up in me ordering their Nankarrow Fabric wrapped readymade Panels in Feb 2021 !!! I needed them on one of my walls which I face while singing. [ I already had a DIY GOBO which I have been using since a couple of years ] . A wide choice of fabric colurs are available. I chose the Olympic Blue Colur Fabric so that it stands out on my yellow wall. Seeing the wall area 600x600mm was the right size, since I already had some red coloured 2x1 ft panels which I had picked up during my visit to the US. And combining with the Nankarrow panels I achieved something very aesthetic plus serving my purpose. The whole process of ordering and delivery was a breeze. In my case there was a small miscommunication in the fabric colur. Ashutosh was extremely nice in replacing the panels with the correct colur This speaks of their commitment to customer satisfaction. Only because of lockdowns there was a delay in getting a carpenter and getting them mounted on the wall. But Once done, it looked amazing and even when I dont open my GOBO the echo in the room is nil. and helps immensely even when I practise my classical music:-) I definitely have plans to do some more treatment in my room especially on the ceiling and lately Aural Exchange have added some new products to their range. !! Thank you Aural Exchange !!

    Couldn't be happier with my purchase (acoustic door seals and door bottoms), and the customer service I received. Products were shipped internationally to Sri Lanka arriving promptly, safely and at a good price, which can't be easy in these current circumstances. Thank you, will definitely be using Aural Exchange in the future

  • Aural Exchange was recommended to me by a friend since I was setting a an audio booth at home. Asutosh whom I contacted has been nothing but helpful from day one. He gave me advice on what I needed, expedited the delivery, and even followed up with me to ensure that I got what I needed. After building the booth he even gave me further advice on placement of acoustic pads etc. Very professional and trustworthy!

    We had a dance hall which we were doubling up to use a place of worship but had bad acoustic issues since the room was filled with mirrors and speech was not clear. Spoke to Aural exchange and they gave excellent advice depending on the budget we had in mind. Great service, sound technical advice and on time delivery. Cant ask for more. Will surely recommend and advice you to connect directly. A small feedback - the website contact numbers need to be updated

  • In my personal experience, Aural Exchange is the best acoustic treatment company out there. A consultant reached out to me immediately after I contacted them for my home studio. I emailed pictures of my room and he responded with excellent advice using only DIY materials. I was able to make nine acoustic panels which have helped eliminate all bass and echo problems without making the room dead. Something that seemed really complicated simply explained and professionally executed.

    Received “Vicoustics Wood Acoustics Panel” from Aural Exchange. Quality of the material, the way the products were packed and delivered exceeded my expectation. Very Professionally managed!! For some time, I was in lookout for Acoustic treatment material. Was trying out Brands available in Amazon. Out of query I ordered “Vicoustics Wood Acoustics Panel” from Aural Exchange. Blown away on the material quality, simply excellent!! All future purchases for acoustics treatment are with Aural Exchange. Just to Add-On. One can have the best gears for music, but unless room is “acoustically right” no gears can sound great

  • When we say knowledge, commitment and professionalism, I think Aural exchange is way better than any of the company in the market. I had a talk with Ashutosh ji 2 month back and he told me to research first about the acoustic treatment and then DIY. He suggested me some articles and videos and I have seen them, they were really impressive and I got to know while talking to him that he has in depth knowledge about his subject. I really appreciate his kindness, efforts and time he has given to me. I strongly suggest if anyone out there wants to have any studio related work.... Please get in touch with Aural exchange and Ashutosh ji. Thank you so much sir.... 🙏

    The experience with AE has been absolutely a great one. From.help in the selection of products to finalising, sorting out my inane queries patiently.Mr Ashutoah definitely deserves a 5 star rating. On the products, they were as mentioned, packaging was high quality, and delivery in these times, well within the given timeline. The products have a great quality feel to them and the taming of sound is great. Have previously tried other sound solutions online. AE's products quality speaks !

For my recording/mixing studio I dealt with Ashutosh Pande and his subject knowledge, communication, passion for acoustics, meticulous attention to detail and all round customer service is first class. He provided exceptional consultancy, recommended and supplied appropriate, high quality treatment solutions and his ability to fully understand my specific environment/requirements ensured a seamless and very successful collaboration. Products were cost effective, delivery was fast and I’m grateful to have discovered this level of care, advice, quality and professionalism. Thanks Ashutosh.

    Superb experience. Professional company. They know their stuff. Ashutosh has been really supportive all through, with e-mails & on call/text. As a professional Voice Artist who wanted to create a home studio set up, I feel pretty satisfied & confident about what all I am getting delivered, both as tangible products as well as the intangible concerned support. Highly suggested. My first small order was for covering up a window in one of the walls. This was honestly also to test waters, since I had never dealt with the company before. I'm glad I made the right choice. Very soon going to place my next bigger order. :)
