Flagship product – LS1be – takes the LS1 performance to the next level. Our aim was to improve transparency even further by focussing on “authority, control and flow”. To achieve this we worked on lowering distortion and extending the linear audio band. We added a new Beryllium tweeter, which was co-developed with Seas. It extends the frequency range and has 9 dB less distortion than our original tweeter. Furthermore we lowered jitter, improved the power supplies, employed some exclusive component selection and decided on silver power supply wiring for the finishing touch.
“We improved transparency even further by focussing on “authority, control and flow”.”
At the low end of the frequency spectrum, we obtained an even bigger improvement. Our newly developed Digital Motional Feedback (DMF) subwoofer has an impressive 30 dB lower distortion, which means the bass area is now just as transparent as the mid and treble. More information can be found at the SB1 web page.
Of course, just like with our other LS1’s, the LS1be frequency response is linearized through smart use of DSP via a Computer Aided Calibration process during production.
The LS1be is accompanied by the LS1r controller and the LS1i USB interface, well known from the LS1. The cabinet can be ordered in a stylish ‘Hi-Macs’ artificial stone finish, in our traditional bamboo veneer look or in ‘all black’.
