OB1i Signature Limited Edition Celebration Model
20 Year Warranty
Following the hugely successful TB2i, FB1i and
PB1i signature series models PMC have been
inundated with requests for further additions to the
i series signature range. We are therefore proud
to announce the release the OB1i signature. This
limited edition signature model has all the cosmetic
enhancements of the current signatures with ne
adjustments of the already exemplary 24db per
octave crossover network.
The OB1i - SIG displays all the ultra high denition
and nesse of the current i series design with added
renement and transparency in the mid, vocal
range. The key to this improvement is subtle tuning
to the crossover network which has been carried
out Peter Thomas himself - designer and founder of
PMC.
Such is the condence in build quality and
engineering excellence the warranty period has
been doubled to a lengthy 20 year period, which is
something enjoyed by all the signature series.

OB1i Signature Limited Edition Celebration Model
The OB1i signature utilises the meticulously engineered six and half inch bass unit, the professionally proven
75mm soft dome and the precision built SOLONEX™ domed tweeter which results in a vast, vivid audio
picture and deep rich bass which can be experienced throughout the room. The OB1i signature’s substantial
ATL™ (Advanced Transmission Line) provides even greater bass extension and control than its smaller siblings
and therefore has the ability to ll a larger listening room with ease.
