Optimized for corner mounting, this 2-pack of matte white Vicoustic Super Bass Extreme Ultra VMT Bass Trap features a light gray front, and it is designed to provide effective low-frequency absorption between 60 to 125 Hz, delivering maximum effectiveness between 75 to 100 Hz. The VMT front provides sufficient mid-high frequency absorption to control corner reflections. When porous materials such as foam are applied to corners or walls, they become less efficient in dealing with low frequencies, because the particle velocity or air movement associated with long wavelengths is low. However, the sound pressure is at its maximum and Super Bass Extreme's internal membrane transforms these high-pressure fluctuations into air motion. The membrane sympathetically vibrates over a 75 to 100 Hz frequency range, causing the air to pass through a layer of high-density foam that absorbs the low frequencies. Super Bass Extreme Ultra is highly recommended for smaller rooms with low-frequency issues. The panel can be used in different corner positions, and its modular structure allows further units to be added as required.

Q: 5. I bought this 128gb card together with ProGrade Digital CFXB,SDXC,SDHC USB 3.1 GEN 2 READER. Check the speed using the h2testw V 1.4 software and disappointed: Write speed-323 MByte/s, Reed speed - 294 MByte/s. What is wrong?

A: The read and write speeds on the card are theoretical speeds that are valid only in a perfect scenario. Nobody really gets the card to work at those speeds. Now the question why one card can be slower than another, it could be the drivers in your computer are slowing down the card, it could be you are connecting the card reader to a USB hub that is slowing down the card, it could be the USB cable you are using is slow, it could be the card is defective. There are so many variables unfortunately. If ProGrade is working faster for you I would recommend returning the Sandisk and getting ProGrade cards.

Q: 6. Other than having velcro, how is using this different than using a standard white vinyl backdrop?

A: This particular product is to add an additional portion for a subject to be placed on when using the Lastolite HiLite. A vinyl background like the Savage Infinity Vinyl Background (8 x 20', White) B&H # SABGIV820W, would come pre-rolled onto a cardboard core and can be used with any background support more easily.
