21. raid to experiment with speaker placement for best results Positioning the speakers within the room will significantly affect the quality of the bass This is because of standing waves caused by bass modes in the room Hence you should experiment with asymmetric positioning in the room Do not have your speakers the same distance from the side and front walls try putting them closer to the left or the right wall If the speakers are equidistance from side and front wall you may find strange suck outs at some frequencies In some problematic rooms a resonance may develop at one or two frequencies that is unnatural to the music By moving the speakers closer to the front side wall or farther from the front side wall the resonance may be reduced at the listener s position The amount of hard and soft surfaces in your room will also affect the tonal balance of your loudspeakers For example with lots of very hard surfaces such as marble or granite floors large picture windows and concrete walls you may find that the room is very bright and you will have to turn the tweeter control down significantly On the other hand large sofas and arm chairs tend to absorb frequencies in the lower mid range and mid bass When your room is full of furniture you may find that you have to turn down the tweeter midrange and bass gain Ultimately an enjoyable and musical system is all about balance You have a number of controls at hand with whic
22. s settings may need to be higher If you have a sealed room with no bass loss the bass gain may be set as low as 2 or 3 Concentrate on the mid bass regions as opposed to the very low bass in your recording to achieve a natural blend The voice and the Genesis 5 3 Owners Manual Ver 2 2 8 music accompaniment should sound as if it were cut from one cloth not separate If the voice sounds thin or does not have enough chest to its sound turn the woofers amplifier s gain up till it does If you find that turning the volume up creates too much low bass and makes the speakers sound boomy you will then need to work on the low pass filter Low Pass filter This control will lower the upper frequency cut off point of the woofer It does not affect the lower frequency cut off point of the mid bass couplers Turning the low pass filter up to a higher number will extend the upper bass regions at the crossover point between the woofers and the mid bass couplers without affecting the low bass level Some rooms may require you to set the low pass filter up to 130Hz while others will require you to lower it down to 80Hz Do not be afraid to increase this control to give the sound more body or to make the balance warmer There is a balance between the setting of the bass gain control and the low pass control The trick is to find this balance A general rule of the thumb is to turn the low pass filter as far clockwise of the 12 o clo
23. s several limitations First turned up too high you may get some distortion on very low frequencies or you may overdrive the amplifier Secondly you may make the mid bass produced by the top of the woofer out of proportion with the mid bass produced by the bottom of the mid bass coupler This would tend to sound boomy in the mid bass regions Another good rule of thumb is to first set the volume control of the woofer for proper midbass rather than low bass The theory is that if the midbass is correct then the low bass should be very close to correct If the midbass is proper and the low bass is still not right here are some other suggestions Genesis 5 3 Owners Manual Ver 2 2 4 5 E T A good balance between proper low bass extension and a deep and spacious soundstage needs to be established to optimize your speaker s performance In order to achieve what the speaker is capable of we suggest you focus your efforts on a proper balance of soundstage elements that includes information beyond the left and right sides of the speakers front to back depth well behind the speaker excellent focus of instruments and voices with proper vertical information and mid bass fill A Genesis loudspeaker system correctly set up can and should provide a soundstage that melts the walls of your room and with pinpoint focus The speakers disappear completely on a recording that has such quality Room Treatment No room is perfect To op

25. tal cone is extremely light and stiff The driver is hence capable of handling the huge dynamic range demands of live music while maintaining extremely low coloration and excellent transient response The Servo bass Advantage Very few loudspeakers use servo drive either because most designers think that it is too difficult to design too expensive or because of the extraordinary demands a servo system makes on the amplifier and the transducer The concept of the Genesis servo bass system is an easy one to understand It employs an accelerometer as a sensor to constantly monitor the movement of the woofer cone and instantaneously compares it to the input signal This comparison circuit identifies any deviation from the input and instantaneously applies a corrective signal to compensate thus practically eliminating the inherent distortion of the woofer As an example when you have a high impact low bass signal that starts and stops suddenly for example a tympani the inertia of the woofer cone makes it slow to start moving and then after it is moving the momentum of the cone makes it continue moving even after the signal has stopped The sonic result is overhang bloat lack of tautness and definition and a blurring of dynamic impact With the servo system the circuit senses that the woofer is not moving as fast as it should and it instantaneously applies much more current to make it move faster When the signal stops it detect
