What advantages do Cylinder Traps have over using no room treatment at all?

1. Tighter, faster, controlled bass with less "overhang".
2. Smoother bass response throughout a room (reduced peaks and nulls at varying room locations).
3. Increased image focus (lack of "smearing").
4. Increased intelligibility (clarity/definition).
5. Elevated location cues (ability to pinpoint location of source).
6. More or less bass output (less exaggeration of low frequencies).
7. Ability to control echo and reverberation within a room.
8. Ability to increase the aural perceptive size of a room or height of a ceiling.
9. Ability to create a "decoupled" acoustically tuneable space within a room.
10. Improve mix translation between varying sound systems (relative consistency in reproduced audio).
11. Ability to create a "roomless" environment (relative lack of room sound).
12. Improve crosstalk between selective instruments/performers within a room.
13. Ability to create separate acoustic "zones" within an room of varying qualities. E.g. Live End/Dead End (LEDE) environments.

What advantages do Cylinder Traps have over panel-type broadband absorbers?

1. Built-in tuneable diffusion.
2. Free-standing, portable, and light weight.
3. Stackable.
4. Visibly less treatment for the same performance.
5. Decor-friendly.

For details on these advantages, visit the Cylinder Trap page.

What advantages do Cylinder Traps have over other tube shaped traps?

1. Less expensive.
2. Smoother, more refined look.
3. Lighter in weight.

For details on these advantages, visit the Cylinder Trap page.

What advantages do Cylinder Traps have over trianglular-shaped corner traps?

1. Portable and can quickly and easily be relocated.
2. Provide poly diffusion, which can be "tuned" on the fly.
3. Can effectively control mid-wall/ceiling reflections, slap-back echo, and higher frequency ringing.

For details on these advantages, visit the Cylinder Trap page.

What advantages do Cylinder Traps have over typical foam sheets/panels that are two to six inches in thickness?

1. Control a much wider range of frequencies, while retaining liveliness and brightness within a room.
2. Effectively control the critical low frequency issues that plague most small to medium-sized rooms.
3. Will not increasingly "choke" or muddy up a room as more of them are added.
4. Are free-standing and portable; do not require surface mounting.
5. Employ integrated and tuneable poly diffusion.

For details on these advantages, visit the Cylinder Trap page.

What advantages do Cylinder Traps have over typical foam treatment twelve inches in thickness or larger?

1. Retain liveliness and brightness within a room.
2. Better low-frequency performance/control per dollar.
5. Employ integrated and tuneable poly diffusion.

For details on these advantages, visit the Cylinder Trap page.

Do you sell monitor stand versions of Cylinder Traps?

Our sixteen-inch [16"] and larger-sized Cylinder Traps can double as monitor stands. Please see the Max Load properties on our Cylinder Trap Specs & Warranty Page.

Is a minimum order of Cylinder Traps required?

No. However, we highly recommend, at minimum, referring to our Cylinder Trap Setup Guidelines Page before placing an order. As with any acoustic treatment solution, a fair number of strategically placed absorbers that are the correct sizes are required in order to expect any relevant sonic improvement. The amount and sizes of Cylinder Traps are highly dependant on the user's environment and his or her goals.

What are the typical shipping costs?

Please see our Options & Pricing Page for more info.


Can I "decouple" my room using a ring of Cylinder Traps?

No, not completely! As with any tube shaped trap, the smaller the diameter of the trap, the higher the cutoff frequency will be. For example, inside a ring of 9" traps, the frequency response curve below approximately 150 Hz will remain relatively unchanged from outside the ring of traps, but will typically have a uniform gain increase of around 3 dB. This is a critical frequency range where many rooms suffer the most. Above 150 Hz, the gain increase tends gradually fall off when the absorptive sides of the traps are facing inward. In this scenario, this problem area is often accentuated.

Are more Cylinder Traps needed than panel-type traps to achieve the same performance?

The important question is whether or not more volume of Cylinder Traps are needed? The answer to that question is no, as long as the Ingredients For Effective Low Frequency Control are applied, just as they are with other designs.

More physical Cylinder Traps may be needed depending on the goal, but keep in mind that the bulk of Cylinder Traps within a properly acoustically treated room will typically be much narrower in width than typical panel-style traps. In other words, the room most likely would not be filled with only 20-inch diamter Cylinder Traps; there would be a combination of different sized traps, the smaller sizes having the highest number count.

Our own reference recording room, which is on the small to medium side, typically contains close to forty [40] Cylinder Traps. If we were to achieve "comparable" performance in that room using another type of broadband absorber from another manufacturer, we would most likely have forty or more of their traps in there. If those traps happened to be panel-style traps, they would end up covering more of the room's surfaces.

Is there anything special about the Cylinder Trap's cylindrical/tubular shape?

Yes and no.

Please see our Acoustic Primer Page for more info on this subject.

What other treatment products, if any, outperform Cylinder Traps?

We own (and use) some of our competitor's acoustic treatments, and based on our own extensive measurements, we have not found another acoustic treatment device that "outperforms" our Cylinder Traps. By outperform, we are referring to overall absorption capability in total Sabines. Furthermore, we have found that our Cylinder Traps perform better in some key areas compared to at least one other competitive product. One of these key areas includes higher absorption capability below 100 Hertz.

Note: We are not including the additional feature of tuneable poly diffusion in the above comparison. This particular feature of Cylinder Traps can significantly add to their total performance capability.

Have Cylinder Traps been measured by an impartial third party?

Not yet, but we do intend on eventually paying for this service. We expect the results to fall in line with our measurements, as we have peformed extensive comparative testing and measurements ourselves in various environments and scenarios using high end recording equipment.

Please see our Cylinder TrapsTM Specifications Page to view these measurements.
