So honestly, will a 15" LVL 4 really perform its best in 3.25 cubes at 1400w rms? if not what would the best size box for # tuned to 44Hz?

I don't know why you would want to tune that high but yes DC subs are designed and built to perform in smaller enclosures with decent port area......I have a local customer that has a Tahoe...I built him a 6.7 cube net enclosure for a pair of DC Audio lvl 4 15s tuned to 34hz..........We took it to a Meca event in Knoxville and he done a 147 @ the headrest on music with a Soundstream Rubicon 2500 on the pair of subs........

Gonna disagree on the small enclosure thing for dc subs in the many test I did with a dc level 4-18 it got louder and louder the larger the enclosure it loved 6 cubes. And it was doing 49's on music meca style truck off at 42hz box tuned 32hz.

Well this would be a spl-fart box. Id stick with my 12 for daily- tuned about 37Hz

While DC can work in smaller enclosures, they typically do not offer maximum performance in those enclosures.

DC recommends 6ft for an 18...

Yep and they tend to be optimal in the larger enclosures can they work in smaller enclosures sure are they gonna perform as well as they should no.

so in short a 15 would do better on the meter in 4.25 cubes with 18sq."/cube than in 3.25 with same port area.

Yes right around 4 cubes for the 15's
