Speakers to make even Raffi sound good?

there's no accounting for taste! "one light, one sun" is one of my reference CDs! just kidding, but hey, you can do a lot worse than raffi.

What is your budget? I have been in the same situation with my family room HT system. Luckily my kid's have moved past the Barney and The Wiggles phase to High School Musical and Ice Age (at least Ice Age is relatively humorous). I ended up with a pair of Polk Audio RTi25s for $140 shipped. When the center channel I used (supposedly voice matched to the 25s) was driving me crazy, I ended up buying another pair of RTi25s for $100 shipped and used one as the center. The Polks are pretty amazing for speakers in the $100-$150 range. I use a small subwoofer with them but if you can't, the RTi35s should be available for $200-$250. The Wharfedale Evo 8s or 10s are also very good small speakers available for $200-$300 used.

This is mainly a theater system but I do listen to 2 channel music a couple of times each week on it and I can't imagine being able to find better $100 speakers.

ads 300's or 310's....their fine sounding and kidproof

Thanks all. I realize that I have been out of this so long, I'm having to look up everything. (Once I found my system, I posted for a while and then stopped. I found that it just made me want to keep upgrading, which I could ill afford to do.) So, I'm not sure what my budget should be. The speakers I'm replacing were $400 new when I bought them 5 years ago! (I can't believe I ever spent that on Cambridge Soundworks. But I used to believe that they were the best speakers.) I have the M60s, not the cubes, so I misrepresented. LOL There is no point in spending more money unless I'm going to get significantly better sound. But if I go up to $700, I can just buy my beloved VR-1s from Von Schweikert. (I can't cannibalize my surrounds, can I? No, my husband would kill me. LOL) So, it would have to be significantly under $700.

You probably aren't all that familiar with the CSW offerings. I know specs are meaningless, but here are the specs for the M60s anyway. I have them hooked up with the CSW bass cube subwoofer:

I'd agree with the Polk recommendation, even the smaller Polk R15's sound amazingly good at their usual discounted price of $79 and I've seen them on sale at Fry's for $49 a pair.

A truly kid-proof option that would be a step up from the cubes would be to get a pair of Radio Shack Minimus 7's off ebay and upgrade the capacitors and crossovers with the kit sold by 'litekeys', also on ebay. The all-aluminum enclosure and grills will take a beating and they do sound pretty nice after the upgrade.
