I have a modest listening space - 13' X 13'. I'm putting together a bang-for-the-buck 2.1 system after a LONG hiatus from listening. I've selected Emotiva's BasX for the subwoofer, but there's still a final decision to be made. Having zero actual ownership experience with subwoofers, which one of the following options to choose:
a. 1 BasX S8
b. 2 BasX S8s
c. 1 BasX S10
d. 2 BasX S10s
e. 1 BasX S12
Decisions, decisions, decision...
Thoughts? Opinions? Recommendations? Musings? Ramblings?

And if you later get the urge you can add another S12. What receiver/preamp/processor will you be using? |

Seems to me, due to the length of low freq signals, the smaller the room the greater the need for dual subs to equalize peaks and valleys at the mlp? A 20 Hz signal has a length of 56.5 feet! Per half wavelength theory, we would need a room of at least 30 feet to have a flat room response down to 20Hz. Otherwise we get resonances (axial - between 2 parallel surfaces, tangential - between 4 surfaces, oblique - between 6 or more). So sound in rooms smaller than 30 feet in length is substantially governed by resonances. While adding 2 subs could equalize peaks and valleys, they would need to be strategically placed to cancel out each other. Otherwise nulls and peaks would result. So the room itself, and the contents therein play a huge part in all this. If absolutely needed, placing the second sub diametrically opposed to the first one may be a good choice (e.g. center front wall, center back wall) rather than stacking them. |

Agreed, and not much music occurs at 20hz. How does it all work at 40 to 60hz? |

While it's true that 2 subwoofers give a better response overall, they may not be needed in a room that size. Do not underestimate the effort to integrate them properly for a smooth response. Start with one, work on room acoustics and see if you need another, you can always add it later. What he said. Properly balancing two subs to get a smooth response overall is going to require a mic and REW at the least and a lot of adjusting assuming you have a proper equalizer or room correction system that's up to the task. Just throwing two subs in with no regard for setting them up properly could make it worse than a single sub alone. If this is your first sub, keep it simple and get one S12. |

I believe both Boom and Nick have accomplished this sans REW, something about a veil being lifted😂 YMMV |

I use to think more than one sub was overkill until I got two. I happen to have the floor space to have two subs one on the left and one on the right the dual subs really make a big difference and they balance the sound stage. Before having two I had no idea of all the left right interaction going on in the bass. I actually had two subs stacked when I had my surround sound system back in 2002 that worked good I had no complaints but I prefer them left, and right. So if you're not planning on getting large floor standers speakers then I'd say get two even if they are small.
