Optimized for corner mounting, this 2-pack or locarno cherry Vicoustic Super Bass Extreme Ultra VMT features a white front, and it is designed to provide effective low-frequency absorption between 60 to 125 Hz, delivering maximum effectiveness between 75 and 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: 1. Is this film available in 120 rolls?

A: Yes it is, see the link below for the 120 format option of this film:http://bhpho.to/1n83Dfu

Q: 2. 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.

Q: 3. Is it possible to purchase the case for this item?

A: You may obtain a replacement case from the manufacturer directly. Please see the link to their contact information: http://bit.ly/1g7INv4

Q: 4. Does the Lastolite 5x7 white vinyl train have velcro on both the short side and long side?

A: the velcro is only on the short side

Q: 5. How can i clean the white one

A: i can even clean the black one well. the material slips off the frame and you can wash it, but it is very difficult to put back on the frame. I just bought a new black one after about three years of use with the first one.

Q: 6. What is the current expiration date on XP2 bulk rolls?

A: This film is currently not in stock and takes about 1-2 weeks and so the expiration date is not available at this time.

Q: 7. Are these compatible with a Canon c300 Mark 2?

A: No, we suggest C-fast cards of 256gb for better run times Such as the following cards SanDisk 256GB Extreme PRO CFast 2.0 Memory Card BH #SAEPC256GBB • MFR #SDCFSP-256G-A46D https://www.bhphotovideo.com/c/product/1317914-REG/sandisk_sdcfsp_256g_a46d_extremepro_cfast_256gb_525r.html

Q: 8. When using this film, is a filter recommended?

A: What kind of filter do you think of? This film, like any BW-film, can be used with filters. It is not a question of the film. It is a question of the result you like to achieve. I would always recommend using filters when working with BW-film in the landscape. Yellow, orange, red turn in different degrees blue darker and the own filter-color brighter. By that you get a darker sky (BW-film mostly translates the color blue not dark enough) or you gain contrast, e.g. between green and red/yellow. Depending on your subject this might be useful. I would be careful doing portraits. Red cheeks or lips are getting pale with a red- or orange-filter. Red-filters are the only ones you have to correct even using TTL-metering. Give plus one exposure. Please mind: you cannot achieve these filter-effects digitally afterwards!! Because if you scan the film you have already a black and white negative. Digital filters are only working turning a colored picture into black and white. The fun with XP 2 is that you can shoot it at different ISOs, let's say between 100 and 400. Best use it at 200 ISO (if the scene is bright enough) - this gives you the sharpest results, if the sun goes away change ISO to 400 within the same film roll - the results get more grainy. Then give it to the next color-lab (C-41 process) to develop. (In fact it is a color-film that produces black and white pictures.) Have fun!
