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

Take a look at the Wharfedale Linton 85th Anniversary speakers with matching stands for $1499 at Music Direct with a 60 day return policy. I bought a pair just for fun on the recommendation of a couple of friends that own Avantgarde Duos and bought them as a change of pace speaker. I placed them in my Family Room which is about the same size as your room and they fill it with ease. I am augmenting them with a pair of Rythmik F-12G’s that were already in place. The combo sounds and looks great to me and the wife. They replaced a pair of Nola KO’s at 10 times the price and I don’t think I have given up that much. You can buy two Rythmik's for the price of one REL.

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.
