I'm considering purchasing RB-25 bookshelf speakers and a RW10 subwoofer (total of around $800), but I just found a co-worker that has a pair of KG3 speakers along with a KG SW subwoofer (circa 1990). He's selling this setup for $200 (includes stands for speakers).
Can anyone comment on how the two setups would compare? This is my first entry into the world of audiophile grade speakers, so I don't know much about this stuff.
I've found out that the KG SW subwoofer is not a "powered" subwoofer. Do powered subwoofers put out quite a bit more sound than non-powered subwoofers? Is the wiring different for non-powered subwoofers.
Also, the KG3 speakers are quite a bit larger than the RB-25, but the KG3 is rated at 65 watts, vs 75 watts for the RB-25. Have the advances in technology since 1990 allowed more power in a smaller speaker?
