The OB1 is a notable addition to the PMC line-up, marking the brand's first foray into 3-way design. This model signifies a substantial enhancement in performance over the 2-way models, providing superior resolution across all frequencies. While it incorporates the same tweeter as the FB1+, the OB1 elevates performance with this familiar component. Central to its design is a dedicated 75mm soft dome mid-range driver, strategically placed in an isolated enclosure, ensuring that critical vocal frequencies are projected beautifully into the listening space, creating an immersive sound experience.

The bass response of the OB1 benefits from a more precise woofer design, delivering cleaner and crisper bass notes and enhancing the initial attack of these frequencies. Transitioning to a 3-way configuration requires a far more intricate crossover network. The OB1 is equipped with a crossover that features steep roll-off curves at 24dB/octave, which not only ensures higher power handling but also achieves a more natural in-room sound response.

To support these advanced components and eliminate unwanted cabinet coloration, the OB1 is constructed with an increased cabinet wall thickness, utilizing a combination of 18mm and 25mm materials. This sturdiness contributes to its versatility, making the OB1 suitable for various environments, from intimate listening rooms to expansive open-plan areas. The OB1 does not restrict high-end upgrades to source equipment; instead, it serves as an optimal conduit, helping the superior quality of components and recordings to be fully expressed.

Purchasing an OB1 is not just about acquiring a speaker but also an investment in long-term quality assurance. By registering the product within 10 days of purchase, owners can secure a 20-year warranty, providing peace of mind and ensuring the OB1 will deliver its exceptional performance for decades.
