guys i have a re sx 15" 1000rms subs... and i already have a ported box built for DD3515.. i want to use this box.. whats ur opinion guys??

here's the enclosure:
box width: 38"
box height: 18"
box depth: 19"
wood thickness: 1"
port width: 4.5"
port length: 3"
box volume(ft3): 4.647
tuned freq: 36.5

can the RE SX handle this box?? the recommendedoptimal enclosure is 4.0 ft3 tuned at 34hertz...
but in DD box calculator it turned out tuned at 40hertz and 4.0 box volume..
