The 125v4 is like a 500 with the boost switch on. It has this really nice mid-bass touch but it doesn't sacrifice the textured growling I have with my sealed subs. It's not like a one-note mid-bass punch. The sound is very nice. Very engaging.

I really think the 125 would be very good for movie effects as well as music in a smaller room like my living room. A very good double-duty sub. It's such a small size too. With that trapezoidal shape, it's easy to fit it under side tables, etc. I like having them out in the open though where I can take in the cherry chestnut.
