Wright Sound WPA3.5 (2A3) monoblocks. Wonderful amps. I've been listening to a pair of Reimer McCullough speakers (6" woofers in an MTM arrangement with a Morel tweeter) for the last three years. They are rated at 93 dB, and go down pretty damn low for a small monitor, but I'm ready for something different and want to experience some big woofers for more realistic bass.Of course I've read the entire range of thoughts on which woofers are best, and am getting quite confused by it all. Everyone has an opionion, and it's always different than the last one!
