Subwoofer for classical music listener

Wow those REL G2s are beautiful!  A little (a lot) out of my price range.  

I was thinking of painting my REL Q108 (It's currently grey) in Gulf auto racing colors, or maybe covering it with fake fur. Tiny mirrors like a disco ball, or a faux Louis Vuitton finish so it looks like a hat box. 

God bless some of you who described the short-coming of subwoofers perfectly.  

I have my share of struggles with them for years.  My current preference is I would not consider to own a pair of speakers if they need subwoofers.   The cost of getting outstanding subwoofers far exceed the additional money to spend more on getting full-range main speakers.

My "outstanding" subs were bought used but in perfect working order, and both were inexpensive at around 200 bucks each. I built my own Neutrik Speakon festooned cables which were also inexpensive using Canare Star Quad cable. One of the the most significant benefits of a good, adjustable sub is that it frees up main speaker buying choices…a speaker that doesn't require a sub simply has a sub in it…one that can't be moved around to help tune the bass to the room, and one that requires the speaker it's part of to be larger and possibly a lot more expensive. Subs are things that encourage Freedom and the American way (!), although mine were made in England.

stfoth:  I finally got around to the idea of trying the high-pass filter option.
I called SVS to order the cables and the rep said I needed powered speakers to go that route.  I don't have powered speakers
