Buggtussel makes a transmission-line sub called the "Tegmentum" that would be an excellent match with the Meadowlarks. The Tegmentum is pretty big, but its quality of bass in my opinion surpasses that of smaller sealed or reflex subs. Rated down to 16 Hz (that's probably a bit optimistic in most rooms), it comes with a very nice crossover/amplifier/equalizer which gives you enormous flexibility in matching sub to speaker: Two independently-variable second order low pass filters; a two-band parametric equalizer; and a continuously-adjustable phase control. You can cascade or stagger the low pass filters, or even bypass one if you need to; and you can use the parametric filters to notch out room peaks or bypass them as well if you prefer.
If you don't want to go with the Buggtussel, then REL also makes some nice subs. But, they're not transmission lines!
Best of luck in your search.
