Aperiodic designs seek to combine the damping of sealed speakers with the efficiency and extension of ported speakers. You pick up bass extension and efficiency due to making use of the backwave from the driver ( like a vent ) but the impedance remains low ( typically even lower ) at resonance like a sealed design. The high impedance peak of a vented design is part of what contributes to the "bloated" or "uncontrolled" low end response that lacks definition.
While it sounds like a phenomenal trade-off ( best of both worlds type of situation ), aperiodics ( also called "vario-vents" by Dynaudio and some DIYer's ) don't sound like either design. How such a design would work in combination with a TL is anybody's guess. Obviously, one would have to listed and see if it was their cup of tea. Sean
