With the DIY Bass Absorber – BDA Broadband Diaphragmatic Absorber plans you can actually build enough low frequency absorption units to tame your room modes without breaking the bank. These plans are lab tested to work at high rates and levels of absorption. The BDA is a powerful, low frequency, absorber that absorbs energy from 40 Hz. – 400 Hz. In fact you get 75% of the performance of our production units, which cost over $1,000 each.

This technology is used by professional recording studio builders when they build a recording studio from the ground up and now you have the blueprints to their design. Once and for all you can have the low frequency attack and decay in each and every note of your bass and drums and for the first time you will able to actually treat your room with your own units that bring all of this to life.

Imperial and metric plans included.

DIY Quadratic Diffuser Build Plans Package

Proper room diffusion is not an option, it is a necessity! Poor diffusion is a room distortion that is present in all rooms both small and large. In fact, it is one of four main acoustical distortions found in your room right now. Diffusion technology is a must in all listening, home theater, and professional recording studios. Now, you have the ability to build your own diffusion technologies. Not just any type of diffusion, but quadratic diffusion which is the most time tested and proven method of diffusion used by professional recording studio builders for years the world over.

This All In One DIY Build Plans Bundle includes DIY constructions plans for our QD-7, QD-11, QD-13, QD-17 and QD-23 Quadratic Sound Diffusers!

Frequency Response for each unit:

  • QD 11 Frequency Response = 375 Hz. – 3,400 Hz.
  • QD 13 Frequency Response = 280 Hz. – 3,400 Hz.

DIY Acoustic Panel Build Plans

With our DIY Acoustic Panels you will have a functioning piece of acoustical furniture for your home theater, personal listening room, or professional recording studio. You will have a foam cabinet that will house your sound absorbing needs but will also add to the overall well balanced look of your studio or listening room. You will be able to create a piece of furniture that has a real wood stain to match the wood stain and finish on your speakers. You will enjoy a foam cabinet that has the correct absorption rate and level for your particular rooms needs and not some generic, one size fits all box, which never will.

The DIY acoustic panels are full build drawings for any acoustical foam to be inserted inside the box. The foam of your choice goes into the box and an acoustically transparent fabric goes across the face. Acoustic Fields can provide you with foam pre-cut to fit your box and the acoustically transparent fabric which is available in over 38 different colors.

We have three thicknesses you can choose from depending on your sound absorption requirements. Our foams go from 125 Hz. – 7,500 Hz. Add them to your shopping cart by visiting our Acoustic Foam page here. If you buy our foam as well as our DIY Acoustic Panels you will end up with a component that is equal in acoustic importance to your amplifier and speaker.

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.

    Would totally recommend them to anybody looking to build their own acoustic treatment. Great stuff!!

  2. Daniel

    I built my complete acoustical treatment with this bundle and Dennis helped with positioning and choice of units along the way. Ridiculously good for this price I have to say. Would totally recommend this to anyone!

  3. grinzy levine

    top one percent eh? OK, I guess that’s me ;) and I’m here to tell you that you’re not entirely correct when you suggest that gear or rooms are the secret to success. I’ve run 3 different large studios over 30 years and mixed a million songs (my fair share of #1’s etc) in great rooms with large consoles, bus loads of O/B and “first rate” acoustics, but please don’t give all the credit to the gear and the rooms. Actually 99% of any success comes down to how you hear it, plain and simple.
    People with great rooms can still suck, sorry…

    • Dennis Foley

      G, Everything in a critical listening environment is all about balance. It is a balance between room size and speaker size. It is a balance between room usage and volume. It is a balance between noise floor and usage. It is a balance between talent and room sound. This variable, I find to be the most critical. One tries to achieve this multilayered balance within budget and location. Due to the complexity and numerous variables involved, some succeed, most do not. Well done, if you have mastered this “jungle”. I am certain your journey has been rewarding due to the effort required.

    I purchased the All In One DIY Acoustic package, Since it doesn’t include a ceiling diffuser instructions. Can I use the QD – 7 build plan and use the same depth measurements but using the P – 7 dimensions – 24 × 4.5 × 24 ?

    My ceiling is 9 to 10 feet high. Also would you recommend to build a P – 7 or 11. Since I have a small room. That is around 21 x 12 Feet.

    • Dennis Foley

      S, Yes, the ceiling modules are that size. Alternate the positioning to create two dimensions of diffusion.

  5. Irving Deschamps

    This is the best bought that I made for my studio. The BDA works amazing. Is not too easy to build (probably you need help), but works very well.

    My fully horn-loaded music system resides along the short wall of a 20x15ft multi use room with a high vaulted ceiling, ridgeline parallel with the short wall. Taming rear wall reflections has been a delicate ballet of listening position, speaker placement and toe-in, and tiny changes in either would make or break the soundstage. A little while ago I started binge-watching Dennis’ youtube videos and came to the conclusion the listening experience might benefit from some diffusion.

    Over the last several weeks I completed a trio of QD-13’s in Cherry and mounted them with a french cleat on the rear wall 24″ off the floor as Dennis recommends.

    I listened to a variety of recordings before and the same ones after the installation. At first I thought the difference would be subtle, but that is not the case. My efforts have been rewarded with a soundstage that is WAY more focused and holographic, and instruments and vocals seem more to occupy physical space as opposed to coming from a point source. The sweet spot is also much bigger and there’s no longer a lobing effect if I move around within it. Speaker placement is more forgiving as well, and toe-in has a more predictable behavior. And yeah, the rear will really does seem to vanish…I know it’s physics, but it seems like sorcery to me. I’m planning to build more for the front wall.

    What a bargain!

    • Dennis Foley

      D, Not sorcery, just physics. Most people will never get to hear music in a truly diffused sound field. Once heard you think how did I ever live without this all these years. Thank you for sharing.
