The OB1 is the first floorstanding model to employ three precision drivers and a sophisticated hand built 24dB per octave crossover. These factors create a major step up in performance with improved resolution in all areas.
The most noticeable feature of the OB1 is the complement of three precision drive units. Between the new PMC/SEAS® developed SONOLEX™ tweeter and PMC’s unique bass unit sits the dedicated 75mm soft dome mid-range, housed in its own acoustically isolated enclosure. This professionally proven drive unit produces a wholly transparent mid range creating clarity of vocal that is truly tangible. The increase in bass definition derives from the stiffer piston-like woofer and upgraded ATL™. The bass attack is immediate and packs a dynamic punch.
Feeding the three precision drive units of the quality found in the OB1 requires a very sophisticated crossover. Therefore, it features a hugely engineered network with ultra steep roll-off curves (24dB/octave) which guarantees high power handling and a supreme natural in-room response.
To guarantee the optimum function of all the featured components the cabinet has been engineered from 18mm and 25mm ultra high density Medite™. This not only creates a highly stable enclosure, but also eliminates cabinet flex and colouration.
As with all PMC designs the OB1 is efficient and can be driven with modestly powered amplification but will excel with more exotic source equipment and is equally at home in medium, and larger open plan rooms.
