Using RG-6 Coax For Audio?

I recently had a problem with my M&K V-125 subwoofer and knucklehead suggested I visit Parts Express for a replacement amp. A subsequent call to them found me inquiring about the audio wires coming from the TV going to the AV receiver. My concern was the distance in my woodshop from where the TV will be mounted from the ceiling to where the A/V equipment rack will be positioned (approx 40 feet).
"Chris" at Parts Express said to use RG-6 coax because the audio out RCA jacks from the TV are line out and that I should also use coax for the subwoofer feed from the receiver to the speaker input.
As of this morning I have all the coax runs completed in the attic.
My questions are:
If coax works in the above situations, why aren't there RCA connectors on speakers instead of the "push the wire in the tiny hole" spring clips?
How does the stiff center wire of the coax get attached to the RCA connector? The connector Parts Express sells says it doesn't require soldering...what keeps the wire from pulling out? Worse, what keeps it from having a loose connection?
Thanks,

Some older speakers do have RCA style speaker jacks on them, Radio Shack brands comes to mind. The problem is the speakers and electric audio components like and need difference specifications in wiring. Coaxial cable works well for low voltage signal transfer because it is a small cable with specifications like low capacitance that works well.
As far as the connector, if it is not a solder connection, it will be a crimp, where usually a center pin is crimped in the center wire, then the rest of the connector snaps over it. They work well.
