I have a fourth order bandpass, and the bass is excellent! It is quite large though, as it has dual 12" subs. These types of enclosures require more powerful speakers and AMPs than a bass cabinet without plexiglass (Meaning, the speakers are not being enclosed, and sound comes directly from the speakers). These BANDPASS enclosures are designed for low frequency. Try listening to anything above 500Mhz in one of these, and it sounds REAL BAD. . .
