Studio Columns are/provide...
Affordability: Studio Columns offer 50% to 75% of savings (and, in some cases, even more!) vs. other arrays.
No Resonant Frequency: Competing devices are most effective at their one tuned (resonant) frequency and give uneven sound fields due to the devices' different diameters. Studio Columns, being passive acoustic devices and constructed of foam specifically fabricated for acoustics, do not have a resonant frequency.
Broadband Absorption: Studio Columns offer superb broad bandwidth control that provides extreme linearity. Acoustical testing shows that Studio Columns across the testing bandwidth differ only +/- 1.9 Sabins. (This is statistically nearly flat and very hard to accomplish.)
Portability: Studio Columns are very light. Because of this, they can be moved, stored, and configured whenever necessary.
Modularity: Studio Columns are sold in singles, so you can make as large or as small an array as necessary. And when the time comes, more Studio Columns can be purchased to create larger and/or new arrays.
Symmetrical Absorption & Refraction: Other arrays use devices of different diameters, which absorb frequencies differently and have different refraction characteristics. These competing arrays create hot spots and nulls in the soundfield (some are only absorbent on 1/2 their circumference). With the common knowledge that room sound is generated by sound waves and their interaction with room boundaries, clearly you need the full 360 degrees of sound-proofing foam that Studio Columns provide for the uniform control of axial, tangential & oblique sound waves for both outside and inside the array.
Foolproof Design: Other devices designed for arrays do not "work" (subjectively & measurably) in some environments. But the Studio Columns, based on the physics of sound control, with their 360-degree design & non-resonant foam, always work in any room!
Bass Absorption: Studio Columns provide a great amount of low frequency absorption at all times. Universally the least understood, difficult to accomplish and most overlooked aspect of acoustic countrol is low frequency control. Mostly all rooms need a lot more bass absorbtion than most people realize. Studio Columns can provide this low frequency absorption, no matter where in the room they are placed.
Added Bonus: Also, as an added bonus, all Studio Columns come with Female Broadband Absorbers - free of charge! After these Absorbers are done protecting the Studio Columns during shippment, they can be used for additional bass trapping as well as broadband absorption. Please make NO mistake: they are NOT just "packaging material" for shipping Studio Columns. They provide about the same amount of sound absorption as the Studio Columns, so you can be sure they can be used to help tame your sound problems.
