I have been using a pair of RT16's as my mains for years and really like them. AT first I had them on the factory spikes in a carpeted room and they sounded great. I then moved and now have them in a larger living room with pergo type floors and glass sliding doors and mirrors. I live in a condo and custom made some speaker platforms out of MDF/concrete block, with sand in between to minimize the bass disturbing my neighbors below. I dont use a sub because I think the 16's go down enough.
My problem is that they now sound too boomy. I have them about 2 ft. from the back wall on the platforms. I have updated the factory spikes to Dayton Audio brass cones. Still too boomy.
I then experimented with putting dacron from an older Polk sub I had in the bass ports. This made the highs and mid-range have incredible tranparency, but lower midrange and bass suffered. I have heard that tipping the speakers back a bit will warm them up somewhat, but I have not tried that yet. Any suggestions on how to integrate the bass in better. I am mainly experimenting with stereo playback, but I can hear it with movies too. Thanks for your help.
P.S. I am using an Outlaw 950 Pre/Pro and Outlaw M200 monoblocks to power them. Using a Sony 200 disc changer.
