Hi everyone, I got these speakers about 4 years ago while I was in Germany, everyone had them and they sounded great! The company is called Ravemaster, as you can see each speaker has 1 tweeter, 2 midrange, and 1 woofer. I made the boxes myself, and are going to prime and paint or carpet them very soon. There are shelves with wool in there to help with the bass. These are all connected to a crossover in the back of each box and would then by speaker wire connect to an amp/receiver. Each speaker is rated @ 250 watts RMS @ 4 ohm, 750 watts max. I used to have them powered by an old Sony home theater receiver that i believe was only 80-100 watts per channel, and these shook the whole house, so now I'm looking for an amp/receiver so I can use these and power these the correct way. What are my options and what kind of companies make something powerful enough? I've spent many hours looking at various integrated amps, stereo receivers ect, but im extremely confused on what would be best for my situation. Thanks for the help!
