The Acoustic Sciences Tube Traps are Black fabric, 11 inches in diameter, & 3 feet tall. As full rounds, 180 degrees of the Tube Traps provide sound diffusion & the other 180 degrees provide sound absorption down to 90 hertz. Between placement and rotation, there are an infinite number of possibilities for refining the acoustics of your listening environment with Tube Traps. Check out Acoustic Sciences' website for a detailed description of the materials, the engineering involved, and potential uses of Tube Traps. Check Acoustic Sciences, Bass Traps, Stereophile, Sound On Sound, Home Theater Magazine, Positive Feedback, etc. for reviews and more.
The asking price is for all three (3) Tube Traps. Fortunately for the buyer, I've changed my listening environment such that these three Tube Traps (3 Tube Traps) are no longer needed. There are no blemishes or tears in the fabric.
Package details are for one 11 inch x 3 foot Tube Trap. Triple the calculated estimate for a more realistic estimate of total shipping cost. I'll refund excess shipping vs. actual fees.
