2 cubes at 32 hz should be fine for this subwoofer, unless you have flaws in the design or build. Are you sure you’re not actually lacking midbass? A 600 watts 12 paired with 15 watt 5.25 inch coaxials up front will likely sound boomy no matter what box your sub is in. Bass boosts an bad EQing can make it even worse. Unless your box is totally flawed in design or build, i would suspect you just don’t have a good enough front stage.
Great info here.
Front stage does *alot* to ensure the "boomy" (generally low-mid bass range, 80-200hz) tones are produced up front and by smaller/more responsive drivers. Being able to comfortably cross the subwoofer over at 60hz basically means it'll blend seamlessly with your front stage... but if you want lots of output up front into the 60hz range you are looking at 8" drivers - 6.5's may suffice, depends on what you are looking for.
You could try poly-filling the box, this can sometimes help dampen "boomy" internal resonance (think echoes in the box)... also if you are looking for more output and greater extension than a sealed box while retaining much of the "punchy" response of sealed - check out passive radiators. Earthquake makes an excellent passive radiator that will give you the ability to essentially build a small but low tuned ported box - something that becomes impossible with any decent amount of port area (more area = longer port... at some point you end up making a transmission line!). The small/low tuned enclosure resolves alot of issues. It would definitely make your setup more "musical" yet retain much of the output gained by going ported... after 20 years of building enclosures I've come to prefer the passive radiator over all other designs.
As long as you keep working toward your goal, you will achieve it.
