I can't believe how much better these speakers sound after I cut out the whole side walls of the midrange chamber...its a night and day difference! All my friends are amazed too.....
When I did this mod on the DCM's I also took out all the wood bracing in the midrange chamber. I also put memory foil from Peter Belt on each midrange driver's frame. I CAN'T STOP LISTENING TO THESE SPEAKERS NOW!
Update on these speakers...I cut the top and back wood off making this speaker a true open baffle speaker. Now they are only the front baffle with no wood around the midrange. This improved things even more!
