Details: Description The Primacoustic Cumulus is a triangular broadband acoustic corner trap that effectively absorbs sound from 125Hz and up. Designed to fit in corners where the walls and ceiling meet, the Cumulus takes advantage of the natural propagation of sound that occurs in all rooms. Sound waves follow the wall and ceiling planes and accumulate in the corners, a well known hot spot in small recording rooms or theater. The Cumulus is amazingly compact. Each side is 24" in length and, when in place, creates a 12" deep air space cavity behind the panel that increases the bass absorption characteristics. Mounting Cumulus traps in a studio will generally yield a significant reduction in the problematic low-mid region while leaving the architectural design of the room virtually intact. Invisible mounting is achieved using spring-tensioned clasps and a single eye-screw. Mounting literally takes minutes and because of the reverse beveled edges Cumulus traps flush mount 'seamlessly' into the room esthetics.This makes the Primacoustic Cumulus the perfect acoustic starting point for rooms such as home theaters or smaller production suits that have limited wall space and suffer from saturation of lower mid-range frequencies (known as 'boomyness'). The strategic placement of the Cumulus in the ceiling corners plus the air cavity it creates there, helps flatten out low-mid room response.Cumulus Details and DevelopmentSound travels through the air in the form of waves. It is well known that walls and ceilings act as waveguides that direct the sound waves into the corners. This is the primary reason why acousticians always start by treating the corners. In essence, you get the most performance with the least material. But even though acousticians have long identified the benefits, the difficulty of mounting acoustic panels in corners and lack of ideal mounting options have discouraged people from taking advantage of this prime room locati

Honestly, the best quality socks for the price. Last a long time and lots of sport and non-sport usage. Trim your toe nails though, this isn't immune to dank toe nail care.

Great Quality Socks!
Number of Items: 6, Color: Black (6-pairs), Size: Large
These Under Armour no-show socks are perfect—comfortable, breathable, and they stay in place all day without slipping. The fabric feels durable yet lightweight, and they wash up nicely without shrinking. Great value for a 6-pack, and they fit true to size. Exactly what I needed!

Good for a few uses
Number of Items: 6, Color: Steel Assorted (6-pairs), Size: Large
Elastic breaks down after a few washes and they become "quitters" and slide down into your sneaker. Very soft and comfortable for maybe a dozen wears

good socks
Number of Items: 6, Color: Red Assorted (6-pairs), Size: Large
I like that they stay on pretty well. also liked the thickness - not too thin / not to thick. also i like that on the inside there are no random threads all over ... i found that to be a problem in similarly priced products from other major brands (and also the cheap options at costco also had that same issue). I've had them a few months and I think they'll last. *** 1 year Update *** Still great! I think they'll easily last me 2-3 yrs! Love how comfy they are. easy to pull on / off. nice colors. highly recommend. I bought some road runner sports socks for almost 5X the price at the same time i got these and while the road runner socks are pretty good for sports (they fit tighter so tend to stay on in active mode), i find these under armour socks much more comfy for daily wear.
