Center: -4.5 dB
Front Right: +4.5 dB
Rear Left: -2.5 dB
Rear Right: -7.0 dB
That is with just one sample point. I took a roll of paper towels and stuck it into the couch vertically, then put the mic on top of that. (About where my head would sit.)
The Original Carver Amazing Loudspeaker is very inefficient. I don't have the spec sheet in front of me, but I want to say it's about 82 dB @ 1W/1m. Minimum wattage recommended is 300 per channel, maximum of 1,000 watts I believe. I knew when I bought them that I would need an external amp, and my old receiver didn't have a pre-out so that lead to the purchase of the 1900.
I found an older Carver TFM-45 amplifier on eBay and got it for a good price... unfortunately, the people that sold it to me had to go out of town and it won't get shipped for two to three weeks. (Listing said 6-10 days for processing and shipping.)
Thank goodness that patience is a virtue, and that I got the amp at a good price... I realize that "life" happens, but you would think that somone with an eBay rating over 99.7% positive and over 8,000 transactions would have their stuff together better than that.
I can't wait to get the amp hooked up and rerun everything. It sounds great now... I can't imagine how it will sound with the right amount of juice.
