At the heart of every personal audio project lives someone craving the meaningful experiences only sound and music can provide. The listener deserves an experience unmarred by mechanical imperfections and acoustic inconsistencies of the speaker. That’s why MISCO designed the 93085: A unique full-range loudspeaker that reproduces music as accurately as possible for high-end, single transducer systems without cross-over requirements.

To achieve faithful reproduction, the 93085 has a sensitivity of 93 dB SPL, a hard fiber dual-cone and cotton spider to optimize dispersion and damping capacities for an ideal transient response, and an EBP of 86 to fit within either a sealed or vented enclosure so you can apply your personal listening preferences to this driver’s strong bass reflex. If you’re looking for true audio fidelity, then this is the speaker for you.

Oaktron by MISCO is a premium line of high performance, ready-to-ship transducers and drivers for a wide variety of applications. From elegantly simple to highly specialized designs for unique and demanding applications, there is an Oaktron loudspeaker perfectly suited for your needs.
