Help with box tuning?

[DJSlowfets]

Got a Sundown Audio e12 v2 500 watts rms dont want to build my own box(I know lazy) found a prefab on ebay for cheap have all the dimensions and it comes out to have a total volume of 1.7 cubic feet.. What do you think it would be tuned at most likely with those dimensions hoping for a box with 1.7 cu ft with a tuning from 32-35 hz. Would this be a good buy? Is there a calculator to put those dimensions and estimate the tuning?

it says 1.65 cube.. tuning is gonna be 40.5- 42 hz some where in there. but sub displacement would need to be taken in to account first
