    The sub has an option to auto start when bass is detected for what you are listening to. It can be good or annoying because it's not perfectly synced. However you can just turn it on as with other subs and it works perfectly. The fact it has a delay doesn't bother me since I rather use the conviniebce of auto on as need and power save when I don't.

      Hello Jtechman,

      Thank you so much for your feedback!

      We are really thrilled to hear you are happy and satisfied with the exceptional bass sound quality of our SA-CS9 115W 10” Active Subwoofer- and that you purchased two for your STR-DH790.

      We greatly appreciate your feedback with the auto power off/on feature of this subwoofer. If there is no signal input for a few minutes, the POWER indicator lights up in red and the subwoofer enters power-saving mode. To turn off this power-saving mode, slide the POWER SAVE switch on the rear panel to OFF.

      You’re going to love the room-filling sound that Mica-Reinforced drivers can deliver. You’ll experience deeper, more precise bass reproduction than ever before and be amazed as your music and movies come alive!

      Thank you so much for purchasing two our SA-CS9 and for choosing Sony!

      Hi MrWoodcock, we're glad you like our product! SA-CS9 gives you deep, rich bass from this powerful active subwoofer, and it includes a built-in amplifier with up to 115 W power output. The unit is powerful and compact, perfect for easy installation in tight spots. Because of the reduced baffle area, the speaker minimizes sound field distortion for optimum clarity and precision. Thank you for choosing Sony. ~Earl Sony_US

    I purchased this to accompany the Onkyo Tuner I purchased as a gift for my husband. I looked at various brands that were more expensive but decided that Sony has always been good to us and was pleasantly surprised that they were one of the least expensive options I was considering. So pleased with this purchase!

    For the price these are great. My only complaint is they are sensitive on the controls. Can go from no bass to too much quickly. Also wish they had an auto off that turned off after 20 min of non-use....the auto setting on them does not work well.

    I bought this to replace a Polk Audio sub that only lasted one year. It works great for me, but I'm no audio snob. I'm sure your higher tier companies will be better for the really particular audio people out there. I just wanted something to add a little base to my setup.

    I would have given more 5 stars if the bass frequency cut off would have more numbers on it. I wanted to place it at 80 but since there is no indicator at that range I had to guess. Some audio experts may do this by ear by playing with the adjustment knob but I am not that good.

    I bought it to add a second subwoofer to my existing Sony sound system. It works well with the old Sony subwoofer on the opposite side of the room. It has a new feature, a frequency filter, which I set to full range to get the best sound.

    This a very good subwoofer for it's price - $200. We got at half price - $100 and that was great deal. It has enough controls to tune it into the room and is a great addition to our home theater audio system.

    Item works well, but lacks the punch required to fill the air in a large room. If you are on a budget, and need punch in a small space, this is a perfect low-cost option.
