7. LOW PASS FILTER SETTING - NO LOW PASS THX MODE
Home Theater receivers and processors provide the necessary high-pass and low pass filtering
(bass management) to ensure proper integration of satellite/subwoofer speaker systems. When
using your subwoofer with one of these components – simply set the switch on models X10 and
X12 for
“LOW-PASS FILTER” on the back of the subwoofer to “ No Low Pass” / THX mode.
X8 shall be set to “No Low Pass” position.
This bypasses the subwoofer’s internal low-pass filter so that there is no interaction between the
subwoofer’s filter and your receiver or processor’s filter. This is the recommended setting for your
subwoofer.
8. VARIABLE LOW PASS FILTER CONTROL
If your receiver or processor does not have an internal crossover, there is another way to match
the subwoofer to your main speakers using the variable “LOW-PASS FILTER” control.
This control sets the upper roll-off point of the subwoofer and allows you to integrate your
satellites with your subwoofer to enjoy full audio bandwidth reproduction from 20 Hz to 20 kHz.
The variable low pass control is a means of fine-tuning the transition of sound between your
satellite or main speakers and your subwoofer, providing a roll-off of 24dB up to 125 Hz.
In most systems, including M&K Sound systems, 80 Hz is a recommendable crossover frequency
for the satellites or main speakers to reproduce frequencies from 80 Hz to 20 KHz, while your
subwoofer reproduces frequencies below 80 Hz.
Whether you use the bass management controller in your receiver or processor or the method discussed
here, this is the most efficient method of reproducing full bandwidth multi-channel audio today.
The satellites, or main speakers, which reproduce the upper frequencies, need only a small cabinet and
small drivers to do their job, while the subwoofer, which reproduces the low frequencies, requires a larger
cabinet, a larger driver and sufficient power in order to do its job.
Properly tuned, your M&K Sound satellite/subwoofer system will provide you with the highest quality sound
reproduction available today.
