[IMR] R1 ZENITH - B STOCK - 3.5mm cable only

R1 ZENITH - B STOCK - 3.5mm cable only
Welcome to the next generation R1, the R1 ZENITH.

Building on the last generation R1's spectacular abilities and reworking and perfecting all areas of the R1, the R1 Zenith has been engineered to offer the most emotional and breathtaking sound.

The R1 Zenith's bass has been controlled even further along with an elevated midrange and more precision in the upper registers. All these improvements have lifted the R1 Zenith's abilities to another level.

Tuned to perfection using IMR's Gen II custom 14mm Ceramic hybrid driver unit. Utilising a hi-res piezo ceramic driver combined with a beryllium 14mm dynamic driver with uprated neodymium motors for a huge soundstage and precise instrument placement and with a FR from 14-40000Hz to cover the whole audible range of audio.

The R1 Zenith includes the updated R1 cables in 3.5mm and 2.5mm balanced termination with the IMR reworked material for a ultra supple and non memory cable.

The unique IMR porting system allows you to alter staging and isolation, the sound stage was spectacular on the R1 but in the R1 Zenith its perfection!

Fully customisable via the porting system and 5 interchangeable acoustics filters to give you 10 settings for your perfect sound signature. These audio filters allow you to alter bass levels, treble levels and increase midrange as required.
