No the term "sub" is VERY abused in the industry. A TRUE subwoofer takes over where the mains leave off. Decent mains should be capable of acoustic reproduction down to 39Hz. Good reference systems don't need a subwoofer in the sense that they will be within 3dB output at 20 Hz. (Laurie Fincham) We do use subwoofers with such systems and they go very very low and take lots of power and the transmission lines are equally big.
This 150Hz bullsh!t is nonsense. This is why I generall don't like three piece systems. The majority of your music CANNOT be accurately handled with a 3.5" driver. No way.
You cannot have too much bass. You can have too much in accurate bass though. True sub bass begins in the single digits or even millihertz. It's a realm that only a handful of systems can touch outside of pyrotechnical helpers which (obviously) are never used in the home!
