The IB1S is an extremely flexible 3-way monitor, which has found its home in the most varied of environments.

Commonly seen in Mastering, Broadcast and Postproduction in either stereo or surround when partnered with its dedicated centre channel and SB100 sub bass system. Its huge popularity in Hollywood film scoring and postproduction is assisted by the option of ‘Film filters’. This gives 2 positions of HF roll off: 1.5dB and 3dB per Oct and Flat position.

The IB1S features wide dispersion soft domed fabric mid and high frequency units and the PMC 10" carbon fibre and Nomex™ flat piston low frequency driver. This flat patented driver increases dynamic handling and eliminates distortion that may occur due to cone break up.

You can find the IB1S in the following studios: BBC Technologies Headquarters.

Customer Reviews

"Rich, balanced, detailed"
Mr S, Longueuil
"The two things I’ve always loved about PMC speakers are the incredible level of detail and the quality and extension of the bass. From the first time I heard PMC at Metropolis Studios in London, I’ve wanted a pair in my own studio. These will quite possibly be the last pair of monitors that I buy."
Mr Matrix (Jamie Quinn) , UK
"These speakers make doing what I love so much easier. "
Troye Lilley Studios, South Africa
"The PMC monitors have proved invaluable because they allow me to understand exactly what I'm hearing and I can therefore make quick, effective decisions that are both musically appropriate and technically sound."
Mr Stephen Marsh, USA
"Thanks to the level of detail and depth you get from PMC, it's much easier to hear exactly what is happening with your mix. They are also very easy on the ears, so you don’t get tired, even when you spend a long time working in the studio. "
Mr Robin Reumers, Belgium
"The IB1S fit perfectly into my studio. A clean, clear, complete spectrum of sound, that feels right. What more could you ask for? "
Mr Mark Maitland, UK
