    This unit is of obvious quality, built to last. It's just that I've been spoiled by owning 2 larger subwoofers that delivered a lot more 'punch' (moved a lot more air) than this guy.

    For $99 dollar deal of the day this is an excellent way to dip your toe into the surround sound world. Quality sound, no distortion. Not the loudest but will work fine for small living room environments.

    Nice 10 inch sub. Lows are respectable. The only reservation is Sony, like many others, cheapens their products by using those horrible spring loaded speaker terminals to wire up with instead of binding posts. I've had those break on me before and you have to replace the whole speaker terminal if you can. You have to use lighter gauge speaker wire to hook up your speakers as well. It would hardly cost anymore to put binding posts on their products. Good for the price, though.

    Tight clean sub with solid bass. At 115 watts it's not going to blow your hair back but it will properly fill a mid-sized room quite well.
