Do you have more information on what, more or less exactly, you're looking for? Like how low does it need to go, what do you use on top, how large can it be, how much power do you have for it, style of music could give a hint also.

The 18LW1400 is pretty allround due to it's parameters, so a lot is possible.

Best regards Johan

Well the type of music is reggae and I'm using the crown xti 2000 bridged. The cabinet on the website doesn't seem to give a good thumb. The sound seem to deminsh when u step away from it. I'm open to any design as long as it's not too huge

I would use it in a closed enclosure without a doubt.
Plenty of headroom. But indeed, it depends on your application.

What design are you talking about exactly?

If it's either the front loaded design (basreflex) or the double manifold/band pass, make sure the speakers are "in phase" . When they're not in phase, the sound deminishes very fast as you describe, you can check this by reversing the polarity of one of the speakers, if the bass reduces in strenght after you've done this, they were in phase, if the bass gets more powerfull they were out of phase.
Also the 18LW1400 needs quite a bit of power to get going, don't give up on it too soon.

What crossover frequency do you use between the subs and tops? There are more power full yet quite compact designs out there but these generally need a crossover between 80 and 100 Hz, to sound their best.

Best regards Johan
