The OB1 is the first 3-way design in the PMC line-up. It represents a step-up in performance when compared to any of the 2-way models, offering additional resolution in all areas.
The OB1 employs an identical tweeter to the FB1+, but attains an even higher level of performance and signal resolution. The addition of a dedicated 75mm soft dome mid-range device, housed in an isolated enclosure, projects the critical vocal ranges far into the room, enveloping you in the performance. Bass is better defined, with the more piston-like woofer, which enhances the attack of bass notes, making them cleaner and crisper.
Moving to a 3-way device involves a far more sophisticated crossover network. This crossover has steep roll-off curves (24dB/octave) which guarantees higher power handling and far more natural in-room response.
To ensure the optimum functioning of all these highly specified components and eliminate cabinet colouration, the OB1 cabinet wall thickness has been increased to a combination of 18mm & 25mm.
The OB1 is at home in a multitude of spaces, from small to larger open plan sitting rooms. The OB1 will not inhibit extreme upgrades to source equipment, they simply act as a conduit allowing the quality to flow through.
PMC’s unique (Advanced Transmission Line) enclosures have taken loudspeaker design to the highest level, using sophisticated cabinet construction, proprietary drive units, and patented absorption materials and techniques. The benefits are enormous compared to the relatively simple sealed and ported designs currently available elsewhere. Find out more
