Very nice write up Pete B. I pretty much agree with your observations. The 6 is fantastic with jazz and classic pieces. Blues are also great providing you don't try to run them in concert levels. I am the original owner of 2 Imperial 6-Gs. In the 70's I work for a quality stereo retailer and have listened to many speakers. The 6-g at the time gave me the best sound value. Comparable to speakers costing 100s more. 6-g was so efficient even the budget receivers can power them very well! The 6-g with the Marantz 4270 and Dual 125 lasted to this day reliably with no distortion. A number of my friends are musicians and enjoy this setup very much. Some may tweak the bass/treble, not too much as everyone's taste is different. Tweaking the L switch did not do much as the tweeter depends on the music selection can be a bit bright. In a fairly large room and the speaker set a couple of feet from the wall. The speaker shines despite its size. In smaller enclosures, the low range can get a bit overpowering as you increase the volume. I find loosely stuffing cotton rags in the ports helps make them brighter. Lately I inherited 4 6-g and a Marantz 4270. They were used in a very large open room. I set up the new system in the cellar. The receiver set up in 4 channel mode and found huge disparity in sound among the speakers. So of course, I tested all 6 speakers by checking polarity, spl and sound of each individual drivers. 2 tweeters and one low range driver was defective. All from the inherited speakers. I suspect maybe the 4270 may be too much power. Swapping the bad for the good, I was able to get 4 good speakers. What is interesting is one pair uses what looks like fiberglass sound deadening. Another pair uses foam padding. The last pair uses sound deadening panels you would use on walls for accoustic! Surprised to see this from the same model speakers. Well, I notice each panels changes the nuance of the sound. I was used to the fiberglass material so naturally I choose that sound. The foam padding sounds too bright, as if the padding is not absorbing the sound much. The padding looks like the pads you would find in furniture. The acoustic padding is much better and makes the sound a bit boomier. I kept the acoustic padding and the fiberglass and gave the last pair with defective drivers to a vintage shop that restores speakers. I expect it be on eBay soon. Now, I'm using the 4270 with the accoustic panels speakers in front and the fiberglass panels in the rear. Seems like an interesting setup in quadraphonic mode. The fiberglass being 'quieter' provides a real nice setup. Now to have the musicians provide insight.
