Or Revel, KEF, Focal (except Grande Utopia which has a built-in 18" sub), Dynaudio, or any other tower that does not have a "built-in sub" (like RBH T2 and above).
A while back after I had auditioned B&W 800D, Salon2, Orion, and owned Definitive BP7000SC (14" built-in sub), I auditioned the RBH T2, which has a real subwoofer as part of their "modular tower". Man, I was utterly enamored by the T2's bass.
No other tower from any other company has the kind of bass that matches the T2 (or great subs) -- not Revel, B&W, KEF, Definitive, etc.
