Possibly the Infinity Monitor Jr. An aperiodic port design is basically a leaky sealed cabinet which uses ports filled with foam that allows better bass response from a smaller cabinet compared to a sealed design but without the impedance peaks typical of a ported design. Aperiodic loudspeaker design.
Aperiodic Loudspeaker Design, The aperiodically damped loudspeaker system is described by the parameters used for sealed box loudspeaker systems. Although at very low frequencies it is just leak really. In the first part of the project Ntanavaras details the build of this compact two-way loudspeaker with an aperiodic loading an open vent filled with resistive material on the front baffle of the enclosure. The theory of the aperiodically damped loudspeaker system N is derived and investigated in both the time and frequency domains.

Oct 30 2013 - Information about Aperiodic Loudspeaker Enclosure Design. I think aperiodic vents are much less well understood than they deserve to be and they could be a very useful tool in the designers toolbox. Acoustic suspension was a more viable solution in older eras of loudspeaker design when one-way linear excursion could be around 5mm but modern designs aim for much larger excursions where high compliance suspensions become impractical. Designing Aperiodic Membranes is a difficult task.
Need to re-measure though and was wondering if aperiodic would work.

Sonus Fabers cabinet acoustics are typically based on an aperiodic design which they refer to as Stealth Reflex Para-Aperiodic. The impedance plot tells us what the cone motion is doing because the driver is a reciprocal network and motion on the secondary is reflected back into the primary as a voltage. The aperiodic enclosure vents the inside of the box to the outside air through a damped ported a port stuffed with damping material which is sometimes referred to as an acoustic resistor or resistive portvent.
