Last night at Overture Audio in Ann Arbor I had the privilege of having Allan Haggar from Sumiko (the REL importer) and the great guys at Overture (JB, TJ, Patrick and Tom) give me a private after hours demo of the REL Stentor III. The Stentor III was used with SF Grand Pianos and VERY good Linn electronics (Linn CD-12, and Klimax amps and preamp) in an 18' X 20' room with no real room treatments I could see (except an acoustical dropped ceiling). The demo was very informative and revealing of what a properly set-up sub-bass system can add to good 2 channel system. I particularly like the flexibility of the inputs and controls. It is also most common that the RELs are crossed over MUCH lower than most people cross over most other subs (this Stentor II was cross over at 23 hz).
My advice to you is that you call Terry at Sumiko or try to get Allan (very knowledgeable and helpful) to help you. It is my understanding that, in most cases you will get the best reults from corner placement as that is how they are designed - to use the corner for proper loading (particularly for 2 channel). Since you are using B&W N804's (e.g., a quality speaker and not a small bass challenged satellite), my guess is that a REL Strata or Storm III, properly set-up, would improve your listening experience. And I can tell you from my experience from last night, the Stentor III even improved (and not so subtly) music, in this case solo classical piano with not much info below 70hz, without low bass by improving the sense of realism and greatly improving the sense of the venue.
I am a believer now in what a properly set-up REL can do and have ordered a Stentor III to augment my Hales T8s and Innersound Eros II. But, as always, this is based on my tastes and preferences but YMMV.
