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

Thanks @b_limo . Yes the Watkins are pretty good. I've heard them and was shocked at how deep they go and the natural sound they exhibit. I think you have some valid & good ideas. And $1250 for the S% is a steal. Mine are actually Sumiko S-10's which seem to be a clone of the S-5. It has the same specs but different cone material. (Fiberglass) Plus the Neutrik connector. They integrate  very well just like the Rel. I've had Rel before and just happened to run into these. I love what they do with the whole sound not just more bottom end but the mains sound much bigger. They are discontinued now. I suspect Rel would have sued them if they kept producing them. But Sumiko was the USA Rel distributor for many years

Thanks for the link. they look interesting. My biggest problem with some is their inefficient specs IE 84-85db efficiency. There are a couple I could drive though.
@artemus_5 ,
keep us posted as to what you decide!  We may have other speaker suggestions as well.

I like Sumiko’s as well 👍. I made my brother buy 2 s.9’s to complement his LS50W’s.  I’ve heard people say RELs are superior but I did not find that to be true at all.  
Anyhow, do keep us updated!

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
