Speakers You do not need a speaker system that looks like the touring setup for the Rolling Stones to enjoy theater quality sound.
Modern speakers are far more efficient than their predecessors.
I own modest JBL speakers that blow away much larger speakers so remember, good things can come in little packages. Also, pick speakers appropriate for your receiver or amp. If you have a 100 watt amp, you do not have to get speakers rated for 200 watts or more. A good rule of thumb is mulltiply your amp's power by 1.5. So for a receiver rated 100 watts a 150 watt speaker set will due.
