I currently have some kg4's with a velodyne cht15 sub. I am running them with a cheap kenwood dts reciever that I will be giving the boot shortly. My questions are that my system lacks clarity and mid bass punch. I did plug one of the kg4s in a system run by a 3803 denon and sounded cleaner (which I expected), but still did not have punch. I think the sub may need to go to as it is ported I prefer sealed tight sound. I have really looked hard at the rf-3, but concered that I will have the same problem in blending the 8in woofer speakers with a 15in sub for music 80% of the time. My others include an rc-3, and rs-3 so the rf-3 would be the likely choice, but I need good tight mid range, accurate sound and loud. That si why I am thinking the 10in woofered towers may solve the problem. I listen to a lot of counrty and clean music and I have played guitar for years so me ear hears quality first. Any recommendations on sub replacement, tower choice, receiver choice (I am looking at denon for the 5ch stereo mode)would be appreciated. Thanks
