The SpectrumPanel is an attractive, professionally upholstered acoustic panel that virtually eliminates mid- and high-frequency reflections while balancing out your audio as low as 125Hz. Placing a SpectrumPanel in a room is the equivalent of opening a window at that exact location: mids and highs that would’ve ricocheted off that spot to create an assortment of acoustic challenges are now converted to heat and eliminated from your listening space.

The SpectrumPanel comes standard with top-of-the-line, acoustically transparent, fire-rated fabric. The back is enclosed in micromesh and the resin-hardened bevel adds to its durability while lending it a rich, professional look. Wall mounting is simple while additional mic stand brackets add mobility for specific placement during tracking.

LowerTrap™

LowerTrap™

● A LowTrap with Wider & Deeper Low Frequency Absorption
● Multifaceted Strategy Against Deep Lows: Membrane, Insulant, and Cavity
● Balances Mids & Highs without Sacrificing Liveliness
● 6” Thick, ‘Green’ Bonded, 6pcf Insulant: Better for the Environment, Acoustically Superior
● Stunning 2” Resin-Hardened Bevel and Pro-Grade, Fire-Rated Fabric

Low frequencies are the hardest to control because they have the longest wavelengths and contain the most energy. By maximizing the thermodynamic transfer that happens when sound waves are converted to heat, a bass trap can effectively drain the energy from troubling reflections and leave you with a clean listening environment.

The LowerTrap employs the same 3-tier design of the LowTrap with one modification: a 50% increase in high-density insulant. The added depth significantly deepens its effectiveness while substantially widening the targeted lower frequency range. When this level of performance is combined with the stylish design and finishes offered on all of Dual Acoustics’ products, it’s hard to justify letting unruly bottom end further rob you of a quality listening experience.

QuantumTrap™

QuantumTrap™

● 7 1/2” Deep, Dual-Membrane Multi-Band Absorption
● Controls Room Modes Down to 50Hz and Mid/High Reflections beyond 5kHz
● Internal, Air-Tight Cavity for Ultra-Low Bass Trapping
● Incorporates a Modified SpectrumPanel™ for Balancing Highs, Mids, and Additional Lows
● 6” Thick, ‘Green’ Bonded, 6pcf Insulant: Better for the Environment, Superior Absorption
● Stunning 2” Resin-Hardened Bevel and Pro-Grade, Fire-Rated Fabric

The QuantumTrap is an astounding acoustic panel and bass trap wrapped into a single product. By incorporating two internal membranes, a sealed air cavity, 6” of ‘green’ bonded insulant and a modified SpectrumPanel™ the QuantumTrap achieves some of the most impressive full-range absorption available today. This 7 1/2” deep, multi-band, multi-purpose trap will dramatically improve any critical listening environment and it is the most efficient and cost effective solution for small to mid-sized rooms with limited wall space. Rather than choosing between a SpectrumPanel or a LowerTrap, a QuantumTrap can be mounted for a better version of both in the same amount of space.

Available in a natural maple frame, it looks as beautiful as it performs.

Product Comparisons


The Dual Acoustics product line was designed to offer a simple set of tools for achieving complete acoustic control. The four core components include a broadband panel targeted at mids and highs, two bass traps that offer varying degrees of bottom end control, and a device that does it all: deep lows through ultra-highs.

In addition to size variations, the LowTrap and Spectrum24 both have optional Cloud Mounting Kits that allow for overhead applications. The LowTrap is also offered with a rear-facing membrane that sacrifices a bit of bass control in exchange for the mid & high absorption power of the SpectrumPanel.

Targeted Frequencies


The frequencies that the panel is most effective at absorbing. All of our panels will have a varying effect across the entire frequency range (e.g. LowTraps are still effective as high as 4000Hz) but they are tuned to be most effective in these provided ranges. The QuantumTrap is the exception in that it is designed to handle the entire frequency spectrum. Please see our Riverbank test results.

Depth


The depth of a fiberglass-based panel has much to do with its low-end absorptive capabilities. Once you know you’re dealing with high-density fiberglass (6lb/ft3 or 6pcf, standard in all Dual Acoustics products), the thicker it is, the more effective it is at controlling powerful low frequency waves. There is a law of diminishing returns at play so the most fiberglass we would build into any of our products in 6″. In addition to fiberglass, acoustic membranes and air cavities also play a large role in the design of bass-targeting devices. The addition of these elements adds to the depth of our products as well.

Sizes


The SpectrumPanel is available in 2’x4’, 2’x2’, 1’x4’, and 1’x1’. Our bass traps are offered at 2′x4′ other than the LowTrap & HMLowTrap which also come 2’x2’.

Membrane


Rigid fiberglass is relatively effective at causing a thermodynamic transfer (converting sound to heat) as sound passes through it. However, a more powerful, non-porous membrane will actually flex as low frequencies pass through and, as an effect, greatly magnify the thermodynamic transfer. However, a front-facing membrane (that faces into a room) will actually reflect some mid-range and high frequencies that aren’t powerful enough to pass through it. This is why the LowTrap is offered with the option for a rear-facing membrane. You get a bit less bass absorption with the membrane in the rear but you maximize mid-range and high frequency absorption. The QuantumTrap is the solution to this bass sacrifice as it is built with two internal membranes that strengthen low-end absorption capabilities without exposing a reflective surface for your mids and highs.

Air Cavity


An air cavity, when used in conjunction with high-density fiberglass and/or a membrane, both lowers the effective frequency range while also deepening the absorption capabilities. The idea is to hit the targeted frequencies the hardest when they’re at their most powerful point. If a panel is hung flush against a wall, this opportunity is wasted as the wave will be almost at a dead stop (the moment it hits a wall) when the absorption is being applied. The QuantumTrap is unique in that it offers a rear-facing air cavity as well as a second, internal cavity sealed by two acoustic membranes. The results of this design can be seen in our Riverbank test results.

Front & Rear Absorption


The front and rear of the panel is exposed to maximize absorption surfaces and limit any barriers that would minimize the panel’s effectiveness. Some well known products make the mistake of encasing the back of a low-end device in wood. This not only unnecessarily adds to the shipping weight of the product, it eliminates the possibility for mid/high absorption through the rear and diminishes the return on any air cavity that’s being put to use.

Fiberglass Density


The density of rigid fiberglass plays a critical role in defining its absorptive capabilities. As sound passes through it, the glass fibers need to flex enough to steal the energy from high energy sound waves (thermodynamic transfer) while not flexing so much that the sound passes through them uninhibited. All of Dual Acoustics products use only the highest density rigid glass fiber available: 6lb/ft3 (6pcf).

Fully Encased Fiberglass


Whether the application is a recording studio, a school auditorium, or a nightclub, there is no reason why fiberglass should ever be exposed by any kind of acoustic treatment. Dual Acoustics encases all fiberglass-based products in both micro-mesh and acoustically transparent, commercial grade fabric.

Professionally Upholstered with Fire-Rated Fabric


Put simply, we are not simply folding over the edges of the fabric to create corners on our panels. Each panel has a sleeve with double stitched corners that was sewn and fitted by a professional upholster.

Cloud Mounting Kit


Suspending acoustic treatment from a ceiling offers many advantages including the ability to cover critical first-reflection points above your head, offer a way to hinder floor to ceiling reflections throughout a listening space, and allow for a less visual location of the treatment. In addition, much larger air-cavities can be created behind the treatment that would not be possible in wall or even corner applications. This fact, combined with the possibility of angled ceiling applications (where a wide, variable air-gap can be created), allows for the capabilities of our products to be greatly expanded.

Absorption Coefficients

During the creation of our product line, we worked with everyone from acousticians to interior designers. Many designs were tested and just about every commercially available low-frequency absorption device was bought, torn apart, and dissected. We incorporated some of the best ideas out there, maximized both aesthetics and performance, and then contacted suppliers around the world in search of the lowest prices on premium materials.

The result is some of the highest quality, most cost-effective treatment you’ll find anywhere near our prices. Most importantly, it exceeds even the most stringent performance expectations.

 

Results

This chart shows test results from Riverbank Acoustical Laboratories for the LowTrap and QuantumTrap (additional test results for the LowerTrap and SpectrumPanel will soon be made available). It also illustrates how some of the industry’s top performers (and more expensive products) measure up against Dual Acoustics. It is important to keep in mind that there are three critical elements when it comes to effective low frequency absorption devices and the absence of any one of them could significantly reduce their effectiveness:

● The use of a membrane greatly increases low-frequency absorption
● Leaving the rear of a device open/exposed improves the effectiveness of any air cavity and/or absorptive material
● Fiberglass density is a critical component; typically, the denser (6pcf) the better

This chart excludes some well-known products that fail to employ these basic principles and, as a result, have either questionable absorption coefficients or lack independent test results altogether.
