Acoustical Fulfillment Flex-48 Adaptive Treatment System - Birch

One 16" x 48" x 2" high-end absorptive acoustical treatment panel with brushed stainless steel Flex-Tray and Flex-Shield plus ten MLV pads, six threaded drywall anchors, and six screws


Product Description

The Acoustical Fulfillment Flex-48 Adaptive Treatment System is a first-of-its-kind dynamic acoustical treatment product. It comprises three main components, all made in the USA:

  • Brushed stainless steel Flex-Tray
  • Laser radiused Flex-Shield
  • Fabric-wrapped FulFill Acoustical Panel

The interaction of these components provides absorption, diffusion, and low-frequency control, all in one elegant product.

The Flex-Tray has built-in impalers to wall mount the FulFill Panel. It also has side rails that allow you to install or remove the Flex-Shield easily. The Flex behaves like a barrel-type diffuser with the shield in place, dispersing high-frequencies back into the room. The mid and low frequencies continue through to the FulFill panel, where they are absorbed. The five-inch air gap created between the panel and the shield, combined with the shield's sympathetic vibration, significantly increases the system's low-frequency performance: 0.95 NRC at 125 Hz!

Shape the sound of your room as desired as easily as changing a microphone. For more liveliness, leave the shields in place. For a tighter sound, remove some or all of the shields. The Flex-48 allows for many sonic profiles out of just one room, on-demand.

In the box:

  • One (1) 16 x 48 x 2" fabric-wrapped beveled-edge FulFill Acoustical Panel
  • One (1) brushed stainless steel Flex-Tray with built-in impalers
  • One (1) laser radiused Flex-Shield
  • Mounting hardware included
  • Custom soft case for shield storage available

I would like to thank VK for the wonderful sales assistance, service and prices. This was my first purchase with you and it won't be my last. I only wish I'd discovered you years ago!

I had two Grammy wins this year - Ray LaMontagne & Carolina Chocolate Drops. Both made with help from Vintage King!

In almost 20 years in Pro audio buying, never did I receive a unit so well packed and exactly as described. Works flawlessly. The whole process has been so smooth. I will never hesitate to do business with you guys in the future and will recommend you to everyone I know.

This was my first experience buying something from Vintage King (although I surf the "used" categories on the website frequently!), and, despite being on the other side of the world, I had absolutely no trouble and everything went very smoothly.
Phil T.
The speed of delivery exceeded my expectations! I was VERY pleased that my shipment arrived in time for a scheduled vocal tracking session. The packing insured that my order arrived safely. And the sales staff responded quickly to questions regarding the product.

Thank you so much! Vintage King has been so fair and easy to work with. I can't thank you enough. It feels good to trust such a hefty purchase to folks who are so helpful and knowledgeable. Vintage King is a sound designers dream store.

You guys have excellent customer service and I am excited about the next upgrade I complete on my fifth recording facility. I've been in the studio business for forty plus years. The salesman I worked with at Vintage King was the best of the best. You all rock!

My experience with Vintage King was excellent. The order was here fast considering it was out of stock. The sales person had SKB send it to me directly and I couldn't have been more pleased.
Michael D.
From the minute I placed my order I was kept well-informed through each step in your process. Even though I was buying a comparatively modest piece of gear, your attention to detail made me feel like I was purchasing a six-figure mixing desk.
Thomas W.
I am a new customer of yours. You guys provided me the absolute best deals in ordering all the equipment to power my brand new recording studio. Your customer service is amazing and i will always deal with you from here on out.
