Leslie has been the yardstick by which rotary organ speakers have been judged for many years. When buying a Hammond organ, it is almost obligatory that the organist adds a Leslie tone cabinet to produce the true rotating sound that results from the unique combination of Hammond and Leslie.
In recent years, however, Leslie have taken their specialised cabinet knowledge into fresh fields and launched a range of speakers not specifically designed for electronic organs.
The Model 18 is a combination speaker that houses a single 12" extended range driver, phase-shifted by an internal foam rotor. The cabinet is without internal amplification and it weighs around 70 lbs, and measures 29" x 21 3/8" x 15".
The rotary cabinets designed for organs have changed considerably since the huge wooden tone cabinets of a decade ago. Today they are far more portable without the sacrifice of either tone or volume.
For the new range of Hammond portable organs, Leslie suggest the 825, or 760 cabinets. The 825 contains a 70 watt amp unit, and delivers its power through a 12" driver with sound activated by a foam rotor. The 760 offers 90 watts of sound from two channels of amplification and it's delivered through a 15" bass speaker plus a treble driver. Two rotors (horn and wood bass units) are also part of the specifications.
Top of the tone cabinet range is the 910. This is a large double cabinet containing one 15" bass driver, two 6" x 9" mid-range units and a treble driver. 100 watts RMS are available from three separate channels and the weight of the unit is 60 lbs for the upper modale and 106 lbs for the lower cabinet. Two rotors are responsible for sound movement.
The subject of cabinets and speaker enclosures cannot really be disposed of without reference to Lockwood, one of Britain's oldest established loudspeaker manufacturers.
Lockwood speakers are designed and produced for a wide variety of applications, but it can most commonly be found inside recording studios of the highest specification which monitor their sound via Lockwood enclosures which house Tannoy Red or Gold drivers.
Today the Lockwood range is far more comprehensive and commonly available are the Lockwood Major and the Universal Major. The Universal can be supplied with an optional mounting saddle which will solve many installation problems.
The Auralinear ES-212 Loudspeaker from Amcron was developed to match the dynamic range and linear reproduction of the other Amcron components. Midrange and highs are reproduced with virtually no crossovers, and wide range electrostatic radiators give flat response, low distortion and placed so as to offer a wide dispersion pattern. Bass response is delivered by two 10" long throw woofers in an acoustic suspension environment. The unit handles 75 watts.
Martin produces high power professional loudspeaker systems for all applications. These ranges from personal stage monitoring and instrument stacks to comprehensive four way P.A. systems, incorporating Midas cross-over/limiters. The prime objective in designing these systems is to minimize harmonic and intermodulation distortion at high sound pressure levels. A development programme supplemented by anechoic chamber measurements has resulted in a sophisticated four way system with horn loaded 500 watt 2 X 15" bins operating below 500 Hz, compression drivers and ring radiators covering the remainder of the spectrum, with narrow band operation of the mid range drivers.
