Have you moved away from full range to standmount speakers + subs?

I went from floorstanders to high performance monitors and sub years ago,  my room was the deciding factor.   Recently I went the other way, large speakers , with and without sub.   I'm glad I did , I now have a room that is well damped , so well that my Velodyne SMS 1 barely applies EQ in auto mode.   No more standing waves.   Compact systems can sound great but lack the weight and body of good floor standers.    I had a serious room mode at 40 Hz in my old house that made any large speaker sound boomy,  which is why I went the sat/sub route.

When you think about it, many speaker stands take up the same real estate as many floor standing speakers.....so if the room allows I'll take floor standers any day

Yes, I have been temporarily forced to either listen full time to headphones or purchase a near field speaker setup because I could no longer access my big stereo system due to construction. I tried listening to headphones only for a while but missed speakers so badly I decided to put together a small stereo system. 

My primary goal was low distortion and secondary was a good balance of remaining characteristics.  I went into this thinking It would be very affordable because everything will be much smaller, but I quickly discovered that this was no easy feat without nearly as much amplifier power as my big system to drive small speakers that cost way more than I had imagined.  I found that I really liked the sound of Wilson Audio Tune Tots but after listening for a week at home the missing low end felt like the loss of a family member.  What I finally ended up with wasn't the affordable system I thought it would be, but fortunately also wasn't the most expensive.  I bought two Wilson Audio Watch Dog subwoofers and I am driving them with a Dan D'agostino Classic amplifier and the Tune Tots are being driven by Dan D'agostino M400 amps.  The lesson I learned was the smaller the stereo system, the harder to achieve great sound without increasingly bigger dollars.  Almost inversely proportional it seems like to me.  

My best advice is to buy at least two subwoofers that are designed for music and not for movie LFE to go with your main speakers.  Best of luck to you and try to enjoy the journey.

   First...I realize that some may see posts from MC as offensive I, however, do not. He has a wealth of experience and usually contributes in a constructive manner. His preferences are his own.
   From my previous post I mentioned the use of stand mounts with a sub(s) and added that bass management is also important. Stand mount speakers come with many features and in many price ranges. Some can rival the performance of some towers. The "deep" bass would probably elude most. That's where bass management comes in when using stand mounts with subs.
   A stand mount speaker is capable of delivering sound in a range of frequencies. The lower frequency (bass) of those speakers have a certain limit. Below that frequency is where the sub(s) come in. Relieving the frequencies below the capability of the mains makes the mains (stand mounts) better at delivering their best performance. Bass management can be achieved different ways...whether built into the amp, HT amps, DSP, active crossovers, and others. The best performance of stand mounts and subs must take this into account.
  

You may be able to use small amps on the main speakers with a sub woofer but only if the sub is powered and if it has a high pass filter to take energy out of the bottom of the main speakers.

But I always recall my friend George Bischoff(Melos electronics that were hundreds of tube triode watts) who believed that a good big one beats a good little one every time.

In my case, I was deciding between B&W 705 and 704 (KEF R3 is also in the mix).  BestBuy has them side by side, so I can compare.  I didn't notice any advantage from 705, however, the base quality from the 704 is quite obvious to me.  Driven by Hegel H120 with the right source, the 704 sound stage can be huge.  I doubt I will ever want a even bigger stage. 
From the physics side, bookshelf share one driver for mid and base.  Floor stander have a dedicated mid range.  I would guess a dedicated one will do the job easier and better than the double duty one.
