5. Bass Response and Your Control Room room that s optimized for bass reproduction Ly A lot of factors can conspire to thwart the MRmk3s extended low frequency including room shape room volume and acoustical treatment MRmk8s achieve the best bass response in a This is not a cop out or an apology It s plain old physics in action Luckily we ve armed you with some compensating controls that you can use to optimize the frequency response of the speakers in your particular room Consider the following Low Frequency Response When you put your MRmk3s in a corner or up against walls their bass characteristics change The apparent loudness of the low frequencies increases when the monitors are placed close to a wall and even more so when they are placed in a corner If you have placed the monitors away from the walls and corners and you would like to hear a little more bass try setting the low freq filter 4 switch to the 2 dB position to provide a gentle boost to the woofer If it s still not enough bass try the 4 dB position to provide a little more bass boost High Frequency Response The MRmk3s are designed to provide a smooth frequency response throughout the mid and high range Nevertheless you may decide that you need a little more or a little less high frequencies in your monitors while you are mixing The high freq filter 5 switch provides a gentle boost or cut to the tweeter Remember that boostin
