Opinion of 10", 12", or 15" woofer

excellent advise Jomari. Another reminder to get a SPL meter in the first place, not sure why I keep putting that off! I'm waiting for an email back from HK to see what they say about the hookup. Since it's really a PC speaker, the only inputs are 1/8", so I'd have to get an RCA to 1/8" adaptor. My question to them was if I should use stereo or mono 1/8", I kind of have the feeling it wouldn't matter, but maybe the sub would only recognize stereo...don't know. Again, this is really all for fun and games as the speaker is just sitting here doing nothing. I might go to walmart to get some cable knowing I can return them later if the outcome isn't good.
