35Hz - 25kHz -- A Partial 'Purist'?

It's amazing how much musical information can be found in the lowest bass regions say 30Hz down to below 20Hz, whether classical, folk, instrumental, pop, etc..

Yet, I'm purplexed to see some to many audiophile 'purists' refuse to even attempt to resolve the obvious deficiency in their systems which simply cannot reproduce any musical information in the lowest regions of the frequecy spectrum.

No matter how musical, how refined, and/or how infinite the configurations a good musical subwoofer can offer, the 'purist' simply will not consider adding a subwoofer to supplement their mains. There's too many good subs (you only need one) ranging from $1k to $30k that can be quite quite musical and allow for near-infinite configurations to adapt to most any system and listening preference. And, yes, I am aware there are many more bad subwoofers, but's that's another thread.

As a self-proclaimed 'fundamentalist', my quest is to ensure my 2-channel system is such that any musical information coming from the source stands an excellent chance of being faithfully reproduced for my listening pleasure.

And by adding a musical 18 inch subwoofer, I don't believe I've given up anything.

I would enjoy hearing what others think.
