Floor Stander or Monitor w/ 2 subs? What does the later give up in a large room?


My listening room is also the Living room. My wife would love to get rid of the floor standing Silverlines. I can deal with that since I've had these for a long time. Change is good. But will it be a good move to go to monitors with 2 S-5 Rel type subs? I am considering Watkins Gen 4 speakers. I've heard them and they sound very good. But will they fill a 5000+ cu ft room?. That is my only reservation...size of imaging. What else...or am I wrong in my thinking they will lack anything? I will try them but I'd like to know what to look out 

Thanks

The upshot may be that I build a room for me. I was going to do that 10 or so years ago. Now, maybe I can do that albeit a little smaller than the one from then. This will expand my office into a nice size music room 11 x 21 (will be the golden ratio) the other one which i had planned comprised another bathroom and a large room plus utility room. I was a builder so maybe I can do this in the summer. Problem is that I am covered up with needed maintenance. Oh well...the golden years.

I think the Rels ability to integrate is their key to success. I've had them for 15 or more years now. Thankfully these [popped up at a killer price. Rythmic was on my radar though
OH, BTW to  everyone else. I have a pair of Infinity RS-1 which I plugged into the system. Since I have the 2 subs, I figured it may give me an idea concerning my question. So I took the Silverline Sonatas our of the path and put the RS-1 in. I was quite surprised at how good they did sound for cheap speakers. They lacked the midrange clarity of the Sonatas. My wife an I listened to them for nearly a week. By that time we knew there was no comparison at all. But it was eye opening as to what such small speakers could do. Then I removed the RS-1 and inserted the Sonatas. As soon as the opening note to the 1st song was heard, I just busted out laughing. The Silverlines were so much bigger and better in every way that it seemed ridiculous now to even try a comparison. 
As I reflect, Two things came to mind. Familiarity breeds contempt. I've had the Silverlines for 15 yrs or so. I knew they were a great speaker when I bought them. But somehow I had forgotten. the second is how easy we are to fool with something new. Even though I had these RS-1 for 10-15 yrs, I was somehow willing to believe they were really better than they were. This is why I usually put a new component in the chain and play it a week or so to acclimate it and me. Then I put the old back in. I've seen it happen where the old was better than the new and it was readily shown when put back in the chain.  Now, onward to my new room.....I hope.

LOL, I can identify! I got my Bolero's about 8 years ago and finally stopped thinking changes in my electronic's etc, would bring my other (older) speakers back to life and have stopped trying. Not even close. :-)
So, does a new room mean you’re no longer looking at monitors?  If you are, what’s your budget?  I didn’t see mention of that or maybe just missed it. 
@artemus_5 , do me a favor and take 10 minutes and look at the Salk Songbird.  

They are $1695 in a standard veneer and offer more choices of woods and dye’s than any other speaker builder I’ve seen.  You can get any wood with any color dye you want. Pictures do not do these speakers justice!  Glossy Automative finishes are available too.  
His speakers are really gorgeous. On top of that, the Songtowers use the Hiquphon OW-1 tweeter which is supposed to be very musical and a fantastic tweeter!  They’re $250 a piece.  The midbass driver is of high quality as well; the Seas ER15 from their prestige line.  It should be a nice organic sounding midbass driver that would complement the musicality of the Hiquphon well.   Add in a transmission line cabinet and gorgeous cabinets and you have a winner!   

If you are sold on a standmount, look at the Salk Ellis 1801b.  It uses the same $250 Hiquphon OW-1 and pairs it to a $260, 7” Seas W18 midwoofer from Seas Excel line.  These drivers are used in many of the best sounding speakers out there.  The Ellis has $1000 worth of high end drivers in a stunning cabinet for $2300.  Pretty remarkable.
