    The subwoofer works well with my Bose music amplifier and Klipsch floor soeakers. The bass response is excellent, and there are many songs that have subbase that I didn’t even realize existed in the song tracks. I was able to purchase this at half price and is an excellent investment. You can easily hear down to 28 Hz and can hear all the way down to 20 but at less decibels. I noticed sound of my floor speakers, the mid range and travel is much cleaner since the subwoofer takes over a lot of the base with the floor speakers do not have to work that hard.

    I think, without question, if you aren't a picky audiophile kinda person. This subwoofer gets the job done hands down. Not sure why the price keeps dropping. Buy insurance just in case. The sound projects well and extremely low frequencies.

    This subwoofer is the best out there, thankfully I was able to get it before the sale was off. It has a powerful punch and will shock you by how much bass it has. The best upgrade from my Sony 115W subwoofer. Very Recommended

    Bought this 12" 400w Sub woofer to match my ensemble with Klipsch two tower speakers. Woofer is strong for the entire house, rumble to low bass, on music and watching Top Gun Maverick DVD movie on my surround Klipsch. I am very satisfied with my purchase.

    I really enjoy my Klipsch bookshelf by itself and wanted to add Klipsch Subwoofer to compliment the sound. On my first impression, when i pick it up, it wasnt heavy and its a large box. Then i set up my RCA cables to my Sony receiver STR-DH790. I played music (hip hop) crank the settings and was surprised to hear the subwoofer maxed out. It wasn’t distorted at all. It was clear, loud, filling the room with a big boom, but it wasnt earth shattering loud. I was satisfied with the bass after making some adjustments. My expectations were too high. I was expecting to hit harder because of the size. Maybe i need to upgrade my reciever. Maybe i need more speakers. Overall it sound great.

    What can I say? The title is self explanatory. I purchased this subwoofer when I upgraded our home theater system. Did I consult my wife? Nope. Does she love it? Ehhhhh... its a love hate situation. She loves the wall rattling effect when watching Maverick and it sounds like a Mach 10 test is happening directly over our home. Does she love it when trying to sleep? Absolutely not. Has she questioned her decision to marry me 16 years ago? Probably... but when our children would rather have a movie night at home than hang with their friends on the weekend, all is forgiven. Do yourself a favor and buy the subwoofer. Dont think, just do.

    Very powerful bass with plenty of tweaking to suite your needs. Auto on feature is a tiny bit slow but really nit picking. I do wish it was front ported but that’s a personal preference. Typical of Klipsch it sounds and looks great
