Do you want cleaner recordings and mixes that translate between playback systems? Then don't neglect the ceilings above your console and performers. The Primacoustic Stratus suspends from the ceiling of your mix environment or tracking room to reduce flutter echoes, early reflections, and standing waves. Its high-density glass wool core is effective at treating frequencies from 400Hz to 20kHz, and at reducing reflections between the floor and ceiling. And even better, the Primacoustic Stratus's professional look and modular design allow you to add additional panels as your studio grows. Hardware and supports are included.

Primacoustic Stratus Modular Acoustic Cloud at a Glance:
  • Tames standing waves for an even-sounding room
  • Reduces flutter echo for cleaner recordings and more reliable monitoring
  • Couples with other kits for continuous, attractive coverage
Tames standing waves for an even-sounding room

Smaller rooms - the kind Sweetwater usually sees in home and project studios - are fraught with standing waves. These present themselves as resonant peaks in your recorded tracks and mix environment. Placing one or more Primacoustic Stratus clouds above your console or performers can help tame those standing waves to a manageable level. The Primacoustic Stratus is effective from 20kHz down to 400Hz, where a lot of midrange buildup can occur. Bear in mind that you'll need bass traps to deal with frequencies lower than 400Hz. Your Sweetwater Sales Engineer is happy to help you find the treatment that's right for your room.

Reduces flutter echo for cleaner recordings and more reliable monitoring

When you clap your hands in a room, the "zing" you hear is flutter echo: sound bouncing off the walls, ceiling, and floor. Flutter echo makes it difficult to add the right amount of reverb in a mix and makes it nearly impossible to get a clean vocal or drum recording. The Primacoustic Stratus helps disperse flutter echo from the floor to the ceiling by absorbing some of the sound energy while allowing some to reflect back. This allows for a more natural sound at the monitoring and microphone positions.

Couples with other kits for continuous, attractive coverage

We don't always have control of the rooms we use to record and mix in. And for small and cube-shaped mix areas, a single 24" x 48" cloud may not properly treat a room. Fortunately, the Primacoustic Stratus's modular design lets you connect several kits together to form a large continuous cloud over your console. This is also handy for tracking rooms, where you may need several Stratuses to cover a full drum kit.

What is Certified Open Box Gear?

At Sweetwater, we're so picky that what we call "Certified Open Box" is actually better than what most music retailers sell as "new" gear! Our gear hasn't endured hundreds of people a week plunking away at all the keyboards, fumbling through Stairway to Heaven on every guitar or playing with every fader and knob on a mixer or control surface.

Certified Open Box (also known as a demo) means we’ve had it out of the box for our YouTube channel, displayed at events, tested in our studio, or maybe it was in a customer’s hands for a few days and isn’t ‘factory fresh’ as a result. Every Certified Open Box item we sell has Sweetwater’s 2-year Total Confidence Coverage™ warranty and has been tested and verified up to ‘new’ specs by our factory-authorized technicians to make sure it’s in perfect working order before we ship it to you.

When you buy a Certified Open Box item at Sweetwater, you get:
  • 2-year Total Confidence Coverage Warranty™!
  • Products inspected and tested by our factory-authorized techs, guaranteed to function like new (or better)!
  • FREE shipping on most items
  • Equipment that will MEET or EXCEED your expectations!

The estimated required monthly payment shown which excludes taxes and delivery equals the amount financed divided by the number of months in the promo period, rounded up to the next cent. During the last month(s) of the promo period the required monthly payment may be reduced due to this rounding. These payments apply only with the financing offer shown. If you make these payments by the due date each month, you should pay off this amount financed within the promo period, if it is the only balance you are paying off.
