Best cabinet for heavy bass music

I made a design around the BMS 18n862. My design goal was to have a compact box that goes low. So obviously effeciency is sacrificed (meaning that you need a big amp to drive it).
The design needs a 6 dB boost at 28,5hz Q2 to play as intended.
The Idea behind this was to have a compact speaker for smallish gigs, till 200 people. And to make double 18 inch 500l cabinets for the same speaker if i need to use the full potential of the drivers.

It's not yet build and tested as funds don't allow it :-)

You say you play dub and reggae, are you therefore intending on putting vocals through those 18's? Just curious as to how well the reflex will cover sub, mid bass n vocals with an 18.

  No. Again this is another benefit of reflex cab, if the drivers can do it there is nothing stopping you from running the 18's up into midrange frequencies if you have to, but you shouldn't have to with the correct mid drivers .

  3 way reflex system can do it all really with the correct drivers, it's a blank canvas that can sound like anything you want with simple EQ adjustments. I have a system with dual 18 subs under dual 15+2" tops, the 15s are proper low/mid drivers with no meaningful output below 70hz and the 2" driver is a nice B&C unit. This system covers the whole spectrum with authority, bass guitar sounds fat yet vocals are clear and it even has good high end.. no probably not quite as much sparkle up there as some super tweeters  would deliver but it's impressive what can be done with the parametric EQs in a processor like the DCX. If the tops were 12's instead the low/mids wouldn't have quite as much weight but it wouldn't be too shabby either, unless you compared it to a system with 15s side by side you wouldn't think you were missing anything and the 12's could be much smaller and easier to move. My dual 15s weigh 150lbs dues to a stack of ceramic magnet drivers inside and 44" tall baltic birch cabs, swap in neo drivers and that would drop to almost half the weight, and the cab can be smaller and lighter if smaller drivers are used too. But if you drop down to 10" mids then you'll likely miss some low/mid and want kick bins, so bottom line is design it as a complete system to start and you won't be disappointed.
