    Good for Movies but Lacks Punch for Music

    I purchased the SACS9 subwoofer to compliment my Sony Core tower speakers (SS-CS3). WHAT I LIKED: I liked the build quality, ease of setup, and accurate controls, but returned this subwoofer after testing for a couple days. It did provide good atmospheric bass that I think would complement movie watching. WHY I RETURNED: In my room (15'x20'), the bass lacked the accuracy and punch that I was hoping to achieve for music listening. For example, it did not give kick drums the 'oomph' that I wanted to hear. Moreover, it did not represent low frequencies with equal volume levels. The lower it got, the quieter it became. I concluded that, despite the impressive build quality and features, the 70w RMS (115w Max) amplifier was under-powered. WHAT I DECIDED TO DO: I decided to spend a little more money, and buy the Klipsch R-100SW (on sale for around $175). My Klipsch is 150w RMS (300w Max), and the difference is night-and-day. If you are looking for something for music, I highly recommend getting something with more power.

    These Subs are perfect for my house and for the price point. I am not audiophile status meaning $50,000 and up home theater setup, so I would not recommend these for that person, but for the rest of us they are not only good but they have lasted years. I have a lot of sony products because my other brands didn't last more than a year to a year and a half.

    works fine for me ,after finally getting my new A-V receiver sys. all hooked up together ,as i am still learning about all the new tech. stuff I put together for new entertainment sys,. but I am surprisingly happy w/ outcome so far w/ extra power of wattage, sound is great an getting better as I dial in on the way I can tailor the sound w/ new rec. Still got a lot to learn on new sys. as I had to down load 113 pages of instructions to understand directions for hooking all up, still got a lot to learn w/ all this new stuff. hopefully I,ll get it done cause I still want to hook up more things.

    I was looking to replace our sub at church mainly because of an offensive noise it made when no signal went to it for five minutes and it was shutting down. This one was simply unplug the old on and plug in the new one and it didnt cost too much either. Sounds great .

    Upgraded from a Bose soundbar type system to a full Sony set up. I couldnt be happier with this sub and the rest of my Sony speakers. I paired this sub with an STRDH750 receiver, a pair of SSCS3 speakers, and a SSCS8 center speaker. I am not an "audiophile" by any means, but I think this system sounds amazing. I happened to get all of these components while they were on sale also. Must say it was worth every penny.
