Happy LRS owner. A couple of thoughts for you.
- In order to get LRS to have magic. High pass the input to the amp feeding them and integrate with a sealed sub.I use a 50 HZ high pass filter before my main amp and a Rythmic 15 in sealed sub set at 50 Hz. Little maggies have a difficult time dealing with low frequency input. I think this applies to the .7s as well. My sound is full range in a larger than you would expect room for LRS. Mine are 4 ft from the front wall and 3 feet from the sides.
- Have a nice set of dynamic speakers to swap into your set up. I have a set of old ProAc monitors that provide some variety in my system presentation.
