Yes. The 15" lvl3's are really a better sealed box woofer, but put them in larger ported boxes tuned low and they'll give you some quality output while sacrificing mechanical power handling. Maybe lower tuning to 30hz if you want some better low-end, because the higher qts value is going to want to move the bump up the response curve already.
