Almost 3 Years to the day the original Zenith was launched and is still one of the most sort after models we created.

Here at IMR we have learnt a lot since then and can now apply all that hard gained knowledge to a reimagining of the Zenith.

The Zenith II features an all new hybrid driver module which we call the PUC drive (Precision Unified Ceramic). The PUC is made up of our Ultra wide band 14.2mm CNT ADLC dynamic combined with our all new Piezo ceramic tweeter into a single module.

The new Zenith II can drop bass lower than the original but with control that the previous Zenith could only ever dream of. Combined with a new acoustic lens means we have been able to squeeze an amazing sound stage out of this new module and offer a level of staging usually reserved for much more expensive units and is wide as it is deep.

Midrange is exceptional and moves the game on by some magnitude over the original Zenith.

Treble is now ultra precise, crisp, fast and non fatiguing.

The unique IMR porting system allows you to alter staging and isolation. By rotating the dial you can switch from fully open to closed on the go.

Fully customisable via the porting system and the IMR interchangeable acoustics filters allowing you to fine tune to your preferred taste.
