This is just my listener's opinion, but Castles sound a little dark and closed in and Totems (Model 1 and Mites, I've listened to both) sound somewhat flat and uninteresting. I also have a small room (11 x 13.5 x 8) and use a REL Strata III subwoofer. I put off auditioning subs for years, wish I'd done it sooner. The little Spendors are, in my opinion, far more musical and involving than either speaker you mentioned, and will mate just fine with a REL.
Any small monitors that dont sound thin and bright
Love the sound of Spendors...they do that "space thing" so right...especially with vocals...which is one of my most demanding criteria...but they are pricey...and have limited dynamics and bass...any more affordable options that offer same level of transparency? I have a small room...so mega bass is really not needed...I am also considering Castle Richmonds and Totem mites...are these anywhere near the Spendors?
