Hommage 22 A

 

The loudspeaker system Hommage 22 A is an overall speaker system  using the LM 555 mid-range driver on the 22 A  horn - which was first introduced by Western Electric in the early 1930th -  and the LM 597 tweeter. Each bass cabinet contains two bass drivers of different diameters differing crossover frequencies and adjustable volume. The amplifiers are executed with A/B circuit. The complex field-coil supply unit (with selenium rectifier) with adjustablity as well as the amplifier units were exclusively manufactured for Auditorium 23. The partially active solution  made it possible to power the complete speaker with the best low power eletronics without any negative  interaction  from the activation from the woofer system. 

The positioning of the tweeter can be handled in a flexible manner, e.g. with a mount on top of the horn or with a freely positionable stand element

It´s difficult to verbally communicate the inner qualites and expressive richness  of a system like the Hommage Cinema. To a large extend it defies itself from the well known and internalized HiFi definitions. Because of the tremendously effortlessness way the speaker is able to reproduce sonic occurrences in a perfectly timed manner, music is transmitted into the room with magnificient ease and inner substance, allowing the listener to become deeply involved in the musical event. 

 

 

Facts

 

 

LM 22 A mid-range horn for LM 555 driver. App.105 db efficiency in combination with LM 597 tweeter. Midrange-horn and tweeter use just passive first order crossover. No linearization, no level adjustment, absorption circuit or low pass filter.

 

Woofer: "Two-Way" Dipole with separate transformer-coupled A/B-amplifier for each driver. Just first order low pass filtered in front of each amp, passive, no electrical equalization or linearization. No  absorbing materials. 15" und 10"-woofer. Separately adjustable upper and lower bass level.

The overall system has an efficiency of 105db/1W/1m at 16 Ohm impedance. 3 watt of amplifier power is already sufficient to run the installation. The internal electronics allow separate level adjustment and therefore adaptation on specific room conditions.

 

Workmanship:

All visible wooden parts are manufactured in manual work with solid wood and high-quality textile.The side flanks are available in walnut, cherry, ash or whitewashed (or not) oak.
