The 2027 One Audio IB3 Series subwoofer draws design cues and tech from the award winning Neo IBn3 series. With several new additions to the subwoofer, it has been further tailored towards being as detailed and articulate as possible while still handling excellent power for increased bottom octave output. Great care was taken with inductance mitigation and linearization utilizing three thick aluminum rings as well as an upper pole cap, yielding excellent upper end response and amp friendly inductance levels. A new 3" 4 layer aluminum coil yields 36mm of Xmax while the larger 10" spider increase overall mechanical linearity and excursion to 4" p-p. Kevlar stitched double opposed leads with oversized push terminals and our unique terminal blocks greatly reduce transmission losses to the coil. The new rear open motor topology helps reduce air flow noise as well as aid in cooling the massive aluminum outer heatsink and flow optimized rear exit. The high excursion 6 spoke aluminum frame is ultra rigid and holds the in house machined custom FEA optimized motor structure. Now with the option of a light weight Rohacell cored carbon fiber cone to save a little moving mass, increase overall cone rigidity, and just look on point for those that might want/need this in the SQ build. The 2027 One Audio IB3v3 sets the new standard as to what a higher power sound quality infinte baffle subwoofer should be. From the subtle nuances of a stand up bass, to the bottom octave filling rattling scene in your favorite movie, the IB3 has you covered.
