Dear analog and digital lovers: For we can truly enjoy the MUSIC in any home audio system that room/audio system needs to be a FULL range audio room/ system.
That means not only that can goes not only down to 20hz and over 20khz but that in the case of the low bass range any passive speaker designs ( even if by design it shows full range specs: down to 20hz and over 30khz. ) must be mated in true stereo fashion with at least two self powered subwoofers where the main speakers will handled the frequencies from around 80hz and up and the subs 80hz and down .
Any home system with passive stereo speakers can't honor MUSIC ( with any source alternative. ) with out a dedicated designed amplifier that meets exactly the woofer(s) needs for what was designed and the MUSIC needs to puts IMD and THD at minimum.
Subwoofers more that anything are for stereo systems and as a side " line " need it for home theather. Not the other way around.
@sleepwalker65, I can imagine you already know all those and you already have, don't you?
