Hello Audio enthusiasts! I have a pair of Woodstock speakers , I am not sure of the model number but it is the one with 5 speakers per enclosure - 12" Woofers, two 4" midranges and two tweeters (a paper tweeter and a dome tweeter), with a rating of 75 watts RMS per channel. I have been using these speakers with a Technics AMP SU -X911. I am not sure if the SU-X911 is able to drive these massive speakers. I was wondering if changing the AMP will make a difference. Are the Woodstock speakers being underutilized ? Your suggestions please. Thanks - Nostalgia.
