The SB12 Plus was just gorgeous to look at and so ... easy to handle.
I purchased the sub to set up my second listening room in the garage for 100% music. To my ears, the SB12 didn't have the lower reach that I was hoping for, that I have gotten used to listening with the MFW 15. Maybe it's the smaller size.
I then switched it with the MFW-15 in the primary room to watch a movie. My wife and I both agreed that the MFW 15 was a better sub for our purposes.
I emailed SVS the next morning to request a return authorization and got a prompt reply. But the actual shipping back took 2+ more weeks because the UPS label was never sent. It took 2 or 3 more emails but, nevertheless, I thought that SVS has great customer service and am considering purchasing the PB13 Ultra in the near future from SVS.
