This prevents reflections from the floor and ceiling from even coming into existence, which would impair the precise tridimensional imaging of the music.
Outside that main path, a large proportion of the signal is cancelled out by interference. This moderately priced full-range loudspeaker is characterised by its extremely light paper diaphragm and the voice coil carrier made of kraft paper which, together, ensure absolutely natural sound right through to the highest frequencies.Ī key characteristic of line arrays is that they generate a highly focused sound beam in the vertical plane. The bass section, which radiates to both sides, is supplemented by a line array consisting of eight oval SL 713 - 4 Ohm full-range drivers.

One metre is sufficient, but for full power right to the bottom of the bass range, 2 - 3 metres is preferable.īut the effortless and unobtrusive deep bass is not all, by any means. The precondition for this low-range bass imaging, which uses double-sided radiation, is, however, also to ensure the speakers are far enough away from the wall. Since there is, in effect, no enclosure, the resonant frequency of the woofer is not increased, but in this case even decreased, which enables it to emanate clear, non-compressed extremely low frequencies. With eight WS 25 E - 8 Ohm woofers, optimised specifically as a free-air system, mounted in a folded, but open baffle, they are able to reproduce bass down to below 20 Hz in a most natural, unhurried and completely unexaggerated manner and with no sign of weakness. The "Les Orgues" speaker series, in this case the GRAND ORGUE species, represent exactly that capability. To do credit to a double bass in all its glory without sounding fluffy or over-inflated or, even worse, giving up altogether, is the reserve of very few, outstanding loudspeaker constructions. Only very few speakers are at all able to reproduce the lowest register of a church organ and even then only the very best are able to make it sound as if it was coming from an organ pipe. provided all architectural and interior design services for this $1,000,000 project. We also coordinated all work provided by structural, range equipment, plumbing, HVAC and electrical engineering consultants. Services included design, construction document and construction administration services. An existing 30 year old “qualification” firearms range located in the City of Milwaukee Safety Academy Building was completely demolished and replaced with a “tactical” state-of-the-art small arms and rifle range. A multi-phase project was planned in coordination with the City of Milwaukee Department of Public Works and the Milwaukee Police Department.The toughest challenge for a high-end loudspeaker is to reproduce the lowest frequencies of larger instruments, such as an organ or double bass, with appropriate fidelity. Phase Three provided additional firing bay sidewall ballistic rubber and steel armor plating allowing for 180 degree weapons discharge. This facility accommodates the Milwaukee Police Departments requirement that emphasize tactical training.īoer Architects, Inc. Phase Two provided a complete new ventilation and exhaust system. Phase One of the project provided a new 15 lane firearms range. Range equipment included new monorail target deployment/retrieval systems, target carrier systems, running man system, master range control computer with remote controls, inclined granular bullet traps and safety baffles and ceilings. New fire sprinkler, lighting and exhaust filtration systems were designed. New Ready Rooms and Staging Areas were also designed. coordinated all work provided by structural, plumbing, HVAC and electrical engineering consultants, and provided a full range of architectural services, including design, construction documents and construction administration services.Ĭhallenges included demolition of the existing jail cells to allow for new construction, maintaining security within the Safety Building and greater MC Courthouse Complex and not disturbing utility services in a building that had to remain occupied and functional during completion of this project.įIREARMS RANGE ALTERATIONS, Milwaukee, WI The entire space, which once comprised a portion of the original Milwaukee County jail, was gutted and completely renovated. Work included new waiting area and reception, open office landscape, private offices, conference rooms, work/copy room and storage area. A kitchenette and two toilets were also added. Boer Architects, Inc. completed the construction of a 4,000 sf renovation of the 3rd floor of the Milwaukee County Safety Building.
