Hi I recently purchased some Energy Tempest speakers for my patio/backyard. I'm wondering if I should get a seperate amp to run them and if so what should I be looking for ? I have no idea what to look for... Here's my current set-up: Yamaha RXV-650 2 Athena AS-F1's 1 Athena AS-C1 2 Athena AS-R1's Athena Sub8 (soon to be replaced by JBL E250P) I purchased the Energy Tempests just before winter set in here and only had them hooked for a few weeks. I had them connected to the Speaker B terminals. When I had speakers A+B on, I had to have the volume cranked up high inside for the outdoor speakers to get decent volume. I haven't tried hooking them up to the Zone 2 instead of the speaker B so I'm not sure if that would make a difference ? I'm actually confused because I'm sure I read that the Canadian model of this receiver RXV-650 could not do A+B but mine seems to ? Is there a way to tell if my receiver is Canadian or American model ? I bought it from a Canadian retailer. Is there anybody with a similar receiver that can help me out with this ? The speakers are in for the winter so I can't try out the Zone B yet. I also have a volume control installed for the outdoor speakers and I had it at full volume. I'm guessing to get a good sound from them that I should get an external amp. Could anybody recommend a good cheap amp that could run the Energy Tempests ? P.S. Sorry for the long read and I'm a relative newbie with this home theatre stuff, so sorry if this doesn't make sense.
