Is One Subwoofer Really Not Appropriate For 2-Chnl


I'm asking this question although I've read about this countless of times. I know 2-subs are preferable than 1 in 2-channel listening as they can load the room better for a more even bass response. However, is 1 sub really not appropriate and not recommended? Planning to go with a high-quality monitor + sub.

Anybody used a sub with Dynaudio Confidence C1, Focal Diablo Utopia or Totem The One?

Thanks in advance.

There is a good set of set up instructions on the Sumico site. It is for RELs but works with other subs. I got the soundtrack from SNEAKERS that they recommend and it works well. I think I got it on Amazon.
I'm using a single Rel B3 with my Dyn C1's. The time alignment/phasing is the trickiest part. Took me about a year to get it right. I had thought of adding a second sub but now I personally don't feel the need for it especially now the timing is right. I have my sub setup about 5ft to the right of my right speaker. I could never get the sub to sound right when I tried placing it between the speakers. Nearfield listening is why I guess it just didn't sound right to me.
Consider the trade off; a smallish bookshelf with a set of subs may cost about the same as a larger full range, and the full range, while taking up less room, perhaps, will likely be more coeherent across the entire spectrum.

I tried sub/monitor combos several times over the years and always returned to full range. I found that usually the midrange suffers the most due to the cabinet considerations and size of drivers. However, an exception was the much larger Wharfedale Opus 2-M2 monitor and matching subs. It is a much larger than usual "bookshelf" speaker, which was critical in competing well with its floor standing sibling. You can read it here:

As Jim Smith (Get Better Sound) would say, your budget should be spread over two, not one. Having said that, I have two, it is very difficult to set up two, alone one. Expect to work on it for weeks, maybe months. Both should be driven by a single mono signal. A TRA when used properly will be of immense help. The RatShack meter is useless in setting my subs properly.
I too had this question and found the solution with 2 subs. I use Merlin TSM-mme speakers. The sound is amazing, but pipe organ pedal notes and very low bass were just not going to happen.

I purchased one subwoofer and carefully dialed it in. The payoff was better sound, but the system became somewhat directional. The Merlins did not disappear as well before the subwoofer.

I bought a second sub. I placed one sub next to each speaker stand and carefully dialed them in. Now I get the Merlin magic and low bass. My experience is that 2 subs are better than one. Make sure you use the same model subs and they are very high quality.
