47" Rapid Deep Parabolic Softbox

Beautiful Focused Light

The 47" Rapid Deep Parabolic Octa Softbox has a narrow shape that reduces the spread of light. Compared to a standard softbox, the Rapid Deep delivers a more focused soft light (with the included internal and external diffusers) and sharper shadows and crisp direct light without the diffusers.

Fits Any Brand

Pick your speedring! The 47" Rapid Deep Parabolic Softbox can change speedrings for different brands in a matter of seconds. Profoto, Alien Bee, Elinchrom etc.  We've got you covered.

Easy Fast Setup

The 16 rapid rods attached to the speedring are spring loaded and lock into place with ease.  You can be setup in minutes.  


When it comes time to pack up you don't have to worry about where you're going to store a huge softbox.  The 47" Rapid Deep Parabolic Softbox folds up as one unit and fits in the nice carrying bag.

Pro Grade Construction

Like all Strobepro products, the 47" Rapid Deep Parabolic Softbox is built tough.  High quality fabrics and metal construction.

Best Softbox Ever Tried and Owned.

While I have tried several softboxes out, being regular & deep in shape. I prefer the deep design personally. This softbox is built with very extreme high quality & it shows right away. The light output is fantastic & I find it to be very soft in the manner that I use it. This has to be one if not the top build quality in a softbox that I have seen that does not break the bank yet gives you the best band for your buck. It has grown to be my prefered product to use which is why I had to order some additional ones in other sizes.

Ease of Use is Amazing

Honestly, hands down one of the simplest modifiers I've ever used.

47" Rapid Deep Parabolic Softbox

Much more than I expected in the build quality and the light quality. I will be ordering more of my lighting needs from Strobepro.

Finally, a dream come true

I have wanted a deep octobox for a long, long time, but the strobes that I have would not accommodate the only available deep octobox that was made for Elinchrom strobes. Strobepro made it possible for me to not only have a deep octobox that fits a Bowens mount (or other mounts) but it is also a very mobile modifier and brilliantly designed. The work I've been creating, since buying it, has been a dream come true :)
