Warm/Smooth Tone Needed.

Hello!

I'm looking to purchase a pair of speakers from WGS - However, I know very little about speakers and need some suggestions! I have a VoxAC30 with two Wharfedale speakers installed (30watts/8ohms each). However, these speakers sound very harsh/chimey and become muddy at high volume. I hate this sound!! I am looking for a nice warm/mellow sound without the harsh chimey tone(my high end right now sounds so ear peircing and Its just awful!) I usually use a cleaner tone with very slight breakup(I use my pedals for overdrive) What speakers/speaker mix would you suggest for a thick,warm tone that wont become too muddy? I'm going for a Radiohead sounding tone! I play with a fender tele with lace sensor pickups. (looking to spend $100 per speaker) I was thinking about going with the Reaper speaker but i'm not sure which one...Also, would I be able to mix two speakers with two different wattages? For example, a 30watt and a 50watt? Or would this hurt my tone/overall sound/amp? Thanks so much I really appreciate the help!
