Description
From well-constructed melodies to simple riffs and chords, music has the potential to fuse into your most cherished memories and relationships. You deserve a listening experience faithful to the original recording, without unwanted acoustic distortions or mechanical distractions. For this reason, we designed the 93087, a unique full-range loudspeaker created to reproduce music with accuracy for high-end, single transducer systems without cross-over requirements.
To reach true fidelity, MISCO designed the 93087 with a sensitivity of 94 dB SPL, an exotic banana pulp, dual cone whizzer, a cotton spider for optimized dispersion and damping capacities, and an EBP rating of 98 – making this driver ideal for vented enclosures. With this driver, we guarantee trustworthy, reliable sound for your next home-audio project.
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.
