The OB1 is the first 3-way design in the PMC line-up.

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.
