  • It is powerful

    The good, I use it with a .005% distortion stereo 2 channel amplifier for both old and new music types, and I do not need to use much volume for the amplifier. The control adjustments are on the back of Klipsch 15'' subwoofer. If I play oldies, like the Beatles or just basically older type music from the 60's, 70's, 80's I can adjust the bass at midpoint and it sounds great, if the music playing next has a lot of bass, you have to run to the subwoofer to turn it down fast. My neighbor from the Dominican Republic loves it and the bass, but I panic, I am 66, and when the bass on any song with heavy bass comes on and I have it at mid point, I immediately run to turn down the bass to minimum and it sounds great. I think I am basically not used to the power. To me, I have owned one sony 10'' type subwoofer, 150 watt output and usually have it turned up all the way on all songs, but on this subwoofer, the power is really scary and my wife will not let me bring it from the basement, even when I have it turned down to 1/3. So, it is powerful, you can not be disappointed in the power, or clarity. Bottom line, for me, it seems I have to adjust the bass a lot not to disturb my wife or son, who do not like music or the neighbors, because even in the basement, there is no way they are not going to hear it and I live in a large lot country home in Michigan, and the basement is concrete. It is not a finished basement. If I had carpeting and various sound absorbing materials around, I could enjoy it without worrying about the bass. I have it matched up with 2 jbl tower monitors with 2, 8 inch bass speakers each, plus their other components and sometimes, just those speakers are fine without the subwoofer, but the subwoofer really livens up things. If I had to do it again, I might change to two 12'' klipsch subwoofers, instead of one large 15'' subwoofer. Not sure, if I give it up, and switch, I might be downgrading the system, or buy another 15'' klipsch subwoofer, and just keep both at minimum, so I do not have to adjust them anymore. but turning up the bass to just mid level power, actually... when a song comes on with bass, even Celine Dion type song to get my wife to just come and listen once, as soon as the song comes on at mid level bass, it makes my body jump to action to turn it down, it is clear, but powerful. Maybe a lot better in a non concrete room, outside or in an normal living room. By the way, my wife will not come down into the basement, and is fine listening to her music coming from the basement, while she is on the second floor above the basement. My son does not complain on the third level of the house. I have never turned the base up to maximum and never turned the amplifier up to maximum, I am sure I will get scolded. My wife is the boss, I used to be happy single, just kidding.
