Query: boomy mid/low bass

i have owned a pair for two years, driven by outlaw or adcom amps. I now have enough experience with it to say something solid and objective. These speakers have bright tweeters, good for jazz and classical music where the sound does not get too low. When it comes to mid-bass, it is loose, muddy, boomy and often going out of control to create annoying sound. This is a well-known issue discussed on the polk forum. I have tried different placement/padding, to no avail. I have no experience with other higher end system, so i cannot really tell whether this is what you deserve for the money you pay. But, i am very disappointed, and is ready to move on to a pair of Magnepan MMG. With this experience, i will not recommend LSi9 for a mid-fi system.
