I appreciate your compliment chrapladm.
These cabinets were featured in a thread on another forum ...http://www.audioheritage.org/vbulletin/showthread.php?31407-Richard-Long-s-Waldorf-restoration
They are a modern spin on the classic Waldorf cabinet design by Richard Long of Richard Long Associates (better known as RLA) in the 70s. He originally built them for the dance club that was in the New York Waldorf Astoria Hotel. The 'Waldorf' loudspeaker as it was called become an instant success and the standard for disco dance clubs. Studio 54 was one of many such clubs featuring the RLA Waldorf System. 'Lee in Montreal' is deeply steeped in the disco dance club lore of the 70's and provided me the drawings that I worked from.
I have since liberated the crossover gear that I used with those loudspeakers but I can tell you that I had them configured as 3 way. My notes from that project tell me that I had the active crossovers set at 620Hz and 6200Hz. All crossover elements were 4rd order Linkwitz-Riley (ie: 24 dB per octave). With EQ the scoop reached 30Hz. The dynamics were overwhelming and were guaranteed to startle you if you were not prepared.
The concern expressed by many when I was building these cabs was that the frequency response would be uneven due to phase cancellation of the wave from the scoop interacting with the wave emitting from the drivers. This is a criticism of all scoop designs. Altho I could readily measure those qualities 1 meter in front of the cabinets they had all but disappeared when measured at my listening position 4 meters from the loudspeakers. The system overall was easily corrected with active EQ.
I really liked them. I cannot think of anything that I can compare them too. There size alone leaves an impression upon you! The BMS 4590s are an exceptionally good CD and perform very well in this application. I especially like these cabs when playing quality live recordings such as is the Crossroads 2010 Blu-Ray disc.
