Aptica MKII SE

Aptica MKII is the result of years of research in the field of transmission line systems. With a new powerful 6.25" midbass driver and the innovative tweeter diffraction trap DSD system, Aptica MKII affirms its elegant and unique design.


The external appearance, which is dictated by the basic principles of acoustics and enriched by a precious finishing, hides a highly innovative project, capable of making the daily listening experience unique and enjoyable. This is not one of the usual odd shaped speakers that invade the space of your home and are tolerated only because of the function they perform, but rather a contributor to make your home space more warm, cosy and suited to your lifestyle.

The latest revision "Second Edition" or simply indicated as "SE", has allowed us to go beyond the limits of this speaker thanks to a targeted optimization of the crossover to increase its electrical efficiency.

"More power, more sensitivity, more dynamics, more extension, more details ... all in less size."

The MKII version has been developed to further increase the original limits of the Aptica thanks to the addition of a cabinet damping mechanism and a new even more powerful midwoofer, with a new oversized magnet and a new oversized titanium voice coil capable of much more electrical power allowing us to quadruple the sound pressure and improve the range of excursion.


The combination of these elements create a speaker with improved transient response while maintaining a low level of distortion.

The "Second Edition" of our Aptica MKII model features a revised crossover and a new silver internal wiring by "Van Den Hul". This revision has allowed us to get the most out of the Mundorf components from our crossovers.


The electrical optimization has helped us to improve the balance of the sound, maximize the acoustic pressure and increase the control capacity  of any type of amplification thanks to a higher load impedance.


"The result is a more balanced sound with greater transparency and more defined focus and improved dynamics, all with a higher level of control."
