Power handling and system efficiency have been enhanced as well. Like the original Sequel, all materials in your new Sequel II speakers are of the highest quality to provide years of enduring enjoyment and deepening respect. All trim pieces are constructed from selected hardwoods. -
Page 4: Installation In Brief
Sequel II: take great care to assign the same color to the (+) terminal on both the left and right channels. If bass is nonexistent and you cannot discern a tight, coherent image, you may need to reverse the (+) and (-) leads on one side to bring the system into proper polarity. -
Page 5: The Electrostatic Concept
This technique is known as push-pull operation and is a Sequel II User's Manual major contributor to the sonic purity of the electrostatic concept due to its exceptional linearity and low distortion. Since the diaphragm of an electrostatic speaker is uniformly driven over its entire area, it can be extremely light and flexible. -
Page 6: History
However, Lodge had no intention for his device to repro- duce music, because in 1898 there was no way to amplify an electrical signal! As a result, his speaker had nothing to offer over the acoustical gramophones of the period. It was not until 1906 that Dr. - Page 7 The test instrument needed an extremely accurate speaker, but Janszen found that the cone speakers of the period were too nonlinear in phase and amplitude response to meet his criteria. Janszen believed that...

The Sequel II uses no crossover networks above 250 Hz because they are not needed. The Sequel II consists of a single, seamless electrostatic membrane reproducing all frequencies above 250 Hz simultaneously. How is this... -
Page 9: Vapor Deposited Film
This proprietary coating insulates the stator to 3 times its actual needed working voltage and gives the Sequel II a wide margin of safe operation. In addition to the electrical insulation properties, this coating also provides the Sequel II with a durable, attractive finish that dampens the steel to prevent ringing. -

Connect one set of wires to the HI+ clips clips and HI- HI- binding posts of the Sequel II. Then connect a second set of wires to the LO+ and LO- LO- binding posts. Next, connect both sets of wires to the appropriate terminals on your amplifier. - Page 12 Operation Passive Bi-Amplification Passive Bi-Amplification Passive Bi-Amplification Passive Bi-Amplification Passive Bi-Amplification For those of you that desire ultimate perfor- mance, the Sequel II may be passively bi- amplified using the existing internal passive crossover elements.

Page 15: Rules Of Thumb
The low frequencies can either be enhanced or nulled by the position from the front wall. Your Sequel II's have been designed to be placed 2 to 3 feet from the front wall (the wall in front of the listening position) to obtain the best results, however your room may see things differently. -
Page 16: Controlled Horizontal Dispersion
Sequel II is a four foot line source beginning two feet above floor level (See Figure 2). This vertical dispersion profile minimizes interactions with the floor and the ceiling. Figure 2. Your Sequel II speaker system is a 4 foot line Figure 2 Figure 2 Figure 2 Figure 2 source when viewed vertically. - Page 17 Sequel II User's Manual Historically, most attempts to achieve smooth dispersion from large flat panel transducers resulted in trade-offs. After exhaustive testing of these different solution at- tempts, we found an elegantly simple, yet very difficult to execute solution.
