Ok im looking to buy some speakers for an amp i use for my vocals, but im not really sure which ones to choose, i know i want somewhere from 10'' to 12'' maybe and in a simple budget (like no more than $50 a piece)so can anybody give me some ideas?

Thanks in advance,

Well PA speakers, the ones for voice and stuff, are a lot different than guitar speakers. Are you talking about JUST speakers without the box?
Explain what you have for a PA system. Because Im really confused as to why you need just the speaker...
I dont know, i guess all i really have is a couple stereo speakers and an amp type thing ive hooked it up to, so i can plug my microphone into (i know its sounds cheap but its all i can afford) and i just want something a little better quality.
