Endless debate: monitor + sub vs floorstanding

Forget all the previous suggestions and get a large room with Magico Q5s and Boulder amps. Otherwise a used REL sub...I've had all the above mentioned options (except the Magico/Boulder thing...I only heard that in a shop) and in the last year my little used REL Q150 with some modest but well regarded small towers has made me a believer...in my current room anyway.

A lot of good suggestions and thank you all.

The reason I went the floorstanding monitor route with a sub is I basically downsized my system somewhat. I figured using a nice tubed integrated (Rogue Tempest II) pushing the monitors only would free up the amp and let the sub take care of the bass duties. I have the sub crossed at a little below 50HZ and the monitors are full range down to around 42HZ I think it is. After a lot of tuning the sub or trying to integrate it, I know I am close but the bass is a little different than my previous full range floorstanders. In some ways its better because I am getting those bottom octaves :) The bass now is right in the center or centerstage. "Some music" might be overlapping a tad with the monitors. I am going to turn the volume down on the sub some more to hopefully cure the bass hump. A buddy of mine awhile back brought over a test CD and his IPhone had an app to measure frequency response. My bass response was pretty darn even so I know I am close. I am wondering if another sub would help? I do like the idea of my integrated pushing the monitors and letting subs take care of bass duties but not oppossed to an efficient full range floorstander.

I had a choice between the Coincident Pure Reference (floor standing)and their Extreme version which splits the speaker into a mini monitor and sub seperates.The drivers are identical.I was able to listen to both at the same time on amps identical to my own. The Extremes had ever so slightly better focus and a small improvement in the bass but honestly, the differences between the two were minor.

Not much to debate . Two way monitor , coherence . Floor standing , frequency extension . Lets not even talk about subs .

Wait...I want to talk about subs!
