So, I'm starting the process of investigating a replacement for my 30-year-old sub. We've been doing some work on the house and now is a good time to consider the options.\n\nThe dual 12" sub is made from 1 1\/4" MDF including the internal bracing. At 32" tall, 20.5" wide, and 21.5" deep it is visually imposing as well as rather weighty, even under a 50" TV. While it has served us well for 30 years, it's just too big and imposing. There are smaller and better-performing subs available today.\n\nWe do watch movies and TV 40 - 50% of the time and listen to music the rest of the time. We do not have an AVR so there is no DSP capability. The Parasound Halo integrated does have subwoofer outputs and an adjustable HP & LP x-over. The budget is about $1k.\n\nI have been looking at three main possibilities. In no particular order:\n\n\nMonoprice M-12 V2\nSVS PB2000 Pro\nArendal 1961 1V\n\nFrom what I've read, the Monoprice appears to be a slightly better performer than the SVS, but I'm also reading their support can be problematic and they apparently require the entire sub be shipped back rather than just a part should there be a problem. I have not heard any such complaints about either SVS or Arendal. Additionally, I recently purchased a set of 1723 S Monitors from Arendal and can vouch for their build quality and performance. The 1961 1V is intriguing as its side-firing and therefore looks smaller from the front. Being from the same company as the main speakers is also a plus. All three subs offer variable phase control, with only SVS offering an app to manage the sub.\n\nAnyway, what are your thoughts on these three subs?
