QDA S-Series


The QDA series of products incorporates the ultimate of everything in one product. We have quadratic diffusion, broadband and frequency specific absorption all wrapped in a furniture grade wood finish. It is our highest performing product and our most expensive.

The QDA S series of product keeps the diffusion and part of the absorption and wraps it all in a MDF cabinet that is clear coated to prevent dirt and moisture impact. You get a prime number 11, 13 or 17 for the diffusion sequence and our ACDA -10 or ACDA-12 technology in the base. You can choose what type works best for your room and usage. You can choose broadband ACDA -10 absorption from 30 – 200 Hz. or more frequency specific absorption from 30 – 50 Hz. All units are on casters for easy positioning.

With the QDA S series, you get your choice of diffusion and absorption type all in one unit in a cabinet that looks good but without the high cost of wood and paint finishes. The alder wood has a smooth and mellow tone quality that is equal to the more higher priced cherry woods.

These units have special handling and shipping requirements, due to their weight and size. Please call us on 520-392-9486 or click HERE to contact us so we can assist you further.

There’s no one size fits all when it comes to room acoustics. Your room is unique to you. If you see acoustic treatment analysis calculators on other sites, that’s all about marketing but no function. You need a live engineer to look at your room because there are too many variables in play to have a one size fits all solution. And any company that provides a one size fits all solution are just selling a bunch of band-aids that aren’t going to solve your problem. We're offering a REAL and FREE acoustic treatment room analysis, conducted by none other than Dennis Foley, our chief acoustics engineer himself.
