Remarks[edit]
There were 2 generations of this model:
- Generation 1 with Vifa poly woofers and midrange drivers (13cm) and aluminium dome tweeter (This generation was optically identical also already produced under the company name ART, however, this model apparently had only a "singlewire" connection terminal).
- Generation 2 with Vifa horn silk dome tweeter, Vifa paper/carbon fibre bass/midrange driver specially developed for ALR as well as Vifa metal midrange driver with phase plug.
