Endless debate: monitor + sub vs floorstanding


Have made a simple system with Peachtree Inova and Proac Sig 8 Tablettes on sand filled stands. Lovely sound I am quite pleased with though I'm considering either supplementing my beloved Tablettes with a sub bass (most likely the new Rel T5) OR grabbing a pair of full range floorstanders (likely used Proac as well).

Any thoughts on the relative merits of the two setups in terms of expression, detail, dynamic spectrum, musicality and also flexibility? Intuitively, it seems I may have more opportunities to play with and fine-tune the experience using Tabletttes plus sub.

I realize there is probably no perfect answer here. Unfortunately, my opportunities for a good side by side listening comparison of the two systems is pretty much nil.

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 .
Me too. Where is yours located and what is x-over set at? Mine is on the left just behind the speakers and about 10" from the side wall and a little over a foot from the front wall. It fires inward. Crossed over around 48Hz.
After trying a few different locations, my REL Q150E (ebay $150 last year...lucky score) ended up in a smallish corner created by a fireplace (fake) firing forward behind my left speaker. I put an angled Speakon plug on the signal cable and use an angled IEC ac cable so it fits back there nicely without cable squashing. The room has a very good sound at my "sweet spot" and the crossover is set at around 50hz or a bit under...my mains are Silverline Preludes that don't do much under 50hz, but their bass is nice and fast (four 3.75" metal mid/woofers) and they integrate amazingly well with the REL. I put a "chicken head" knob on the volume pot of the REL so I can adjust it readily if need be. All it needs is a couple clicks up or down sometimes depending on the source and how I feel about it.
