FOR SALE: Ambience 1800 Ribbon Speakers (Mahogany Finish)
These speakers were purchased in 1998. They are still working flawlessly. Having moved from a warehouse apartment to single level terrace, I need to downsize and have to part with these superb speakers. As described below the 'soundstage is huge. I still have the original Ambience Technical booklet and set up instructions. (See shot in photos). Demos will be considered for genuine buyers. The price includes the speaker cables. Pick-up only.

All our models (except sub woofer) incorporate the Ambience ribbon driver, which has proven to be extremely reliable and robust.
They have a natural tendency to “ramp” off at frequencies above 16KHz, without the use of electronic filter networks, adding coloration and distortion.
The Bass driver has been specifically developed by SEAS of Norway to match the Ambience Ribbon driver, with a useful lower frequency response well below 30Hz.
A complex third order crossover is fitted to all models.
The crossover point is performed at a frequency less sensitive to the human ear; thus cannot be distinguished.
The resulting combination is a speaker system that has incredible REALISM, coupled with CLARITY that only Ribbon or Electrostatic speakers can produce.
The soundstage is extremely large, and being of di-polar type design, they also have great depth.
Because of their gradual ramp downward tendency at the upper most frequencies, listening is very smooth and relaxing, even when operated at high volume levels!
The 1800 model creates a huge “soundstage” and performs at their best in larger rooms.
